    Description [0001] The invention relates to a method and a device for the targeted component zone-specific heat treatment of a steel component.
    In the art, in many applications in different industries, the desire for high strength sheet metal parts with low part weight. For example, in the automotive industry, efforts are being made to reduce the fuel consumption of automobiles and to reduce CO 2 emissions, while at the same time increasing occupant safety. There is therefore a rapidly increasing demand for body components with a favorable strength to weight ratio. These components include, in particular, A and B pillars, side impact beams in doors, sills, frame members, bumper, cross members for floor and roof, front and rear side members. In modern motor vehicles, the body shell with a safety cage usually consists of a hardened steel sheet with about 1,500 MPa strength. In many cases Al-Si-coated steel sheets are used. For the production of a component from hardened steel sheet the process of the so-called press hardening was developed. In this process, steel sheets are first heated to austenitic temperature, then placed in a press tool, rapidly formed and rapidly quenched by the water cooled tool to less than martensite start temperature. This results in hard, firm martensite with about 1,500 MPa strength. However, such a hardened steel sheet has only a small elongation at break. The kinetic energy of an impact can therefore not be sufficiently converted into deformation heat.
    For the automotive industry, it is therefore desirable to be able to produce body parts that have several different strain and strength zones in the component, so that more solid areas (hereinafter, first areas) on the one hand and more stretchable areas (hereinafter, second areas) on the other present in a component. On the one hand, components with high strength are basically desirable in order to obtain components of high mechanical strength with low weight. On the other hand, even high-strength components should be able to have partially soft areas. This brings 1 the desired, partially increased deformability in the event of a crash. This is the only way to reduce the kinetic energy of an impact and minimize the acceleration forces on the occupants and the rest of the vehicle. In addition, modern joining methods require de-consolidated points, which allow the joining of identical or different materials. Often, for example, crimping, crimping or riveting must be used, which require deformable areas in the component.
    The general demands on a production plant should continue to be respected: so there should be no cycle time loss at the press hardening plant, the entire system should be universally used unrestricted and can be quickly converted product-specific. The process should be robust and economical and the production plant need only minimal space. The shape and edge accuracy of the component should be high.
    In all known methods, the targeted heat treatment of the component takes place in a time-consuming treatment step, which has a significant influence on the cycle time of the entire heat treatment device.
    The object of the invention is therefore to provide a method and apparatus for targeted component zone-specific heat treatment of a steel component, wherein areas of different hardness and ductility can be achieved, in which the influence on the cycle time of the entire heat treatment apparatus is minimized.
    According to the invention this object is achieved by a method having the features of independent claim 1. Advantageous developments of the method will become apparent from the dependent claims 2 to 7. The object is further achieved by a device according to claim 8. Advantageous embodiments of the device will become apparent from the dependent claims 9 to 16.
    A steel component is first heated to below the austenizing temperature AC3 he.
    Subsequently, the steel component is transferred to a treatment station. Here, the second or the second regions are cooled as quickly as possible within a treatment time tB. In a preferred embodiment of the heat treatment apparatus, the treatment station has a positioning device, with the aid of which the exact positioning of the individual areas is ensured. The rapid cooling of the second or the second regions takes place in a preferred embodiment of the method by blowing with a gaseous fluid, for example air or an inert gas. In an advantageous embodiment, the treatment station has a device for blowing on the second region (s). This device may, for example, have one or more nozzles. In an advantageous embodiment of the method, the blowing of the second or the second regions is carried out by blowing with a gaseous fluid, wherein the gaseous fluid water, for example in nebulized form, is attached. For this purpose, in an advantageous embodiment, the device has one or more nebulizing nozzles. By blowing with the gaseous fluid mixed with water, the heat removal from or from the second regions is increased. After the treatment time tB has expired, the second region or the second regions have reached a cooling stop temperature E s. The treatment time tB usually moves in the range of a few seconds. In this case, the second or the second regions can also be cooled to well below the martensite start temperature Ms. The martensite start temperature Ms is for example for the frequently used body steel 22MnB5 at about 410 ° C. The first area (s) are not subjected to any special treatment in the treatment station, i. they are neither blown nor heated or cooled by other special measures. The first or the first areas cool slowly in the treatment station, for example, via natural convection. It has proven to be advantageous if measures are taken in the treatment station for reducing the temperature losses of the first or the first regions. Such measures can be, for example, the attachment of a heat radiation reflector and / or the isolation of surfaces of the treatment station in the region of the first or the first regions.
    Subsequently, i. E. after the treatment time tB, the steel component is transferred to a second furnace. In this second furnace, the entire steel component is heated. The heating can be done for example by thermal radiation. In the process, the steel component remains in the second furnace during a residence time ti30, which is dimensioned so that the temperature of the first or the first regions rises above the AC3 temperature. Since the second or the second regions from the preceding process steps at the beginning of the residence time ti30 have a significantly lower temperature than the first or the first regions, they did not reach the AC3 temperature at the end of the residence time ti30 in the second furnace. Thereafter, the steel member may be transferred to a press-hardening tool, wherein the first and first portions are fully austenitized while the second and second portions are not austenitized, such that quenching during subsequent press-hardening causes the first or first portions to become martensitic Form structure with high strength values. Since the second or the second regions were not austenitized in the process at any time, they exhibit, after the press-hardening step, a ferritic-pearlitic structure with only low strength values at high ductility.
    According to the invention, the components after a few seconds in the treatment station, which may also have a positioning device to ensure the accurate positioning of the different areas, transported in a second oven, which preferably has no special devices for different treatment of the different areas , In one embodiment, only one furnace temperature θ4, i. a substantially homogeneous temperature in the entire furnace chamber, which is above the Austenitisierungstemperatur AC3. Clearly contoured boundaries of the individual areas can be realized, and the low temperature difference between the two areas minimizes distortion of the components. Small spreads in the temperature level of the component have an advantageous effect on further processing in the press.
    Advantageously, in one embodiment, a continuous furnace is provided as the first furnace. Continuous furnaces usually have a large capacity and are particularly well suited for mass production, since they can be fed and operated without much effort. But even a batch oven, such as a chamber oven, can be used as the first oven.
    Advantageously, in one embodiment, the second furnace is a continuous furnace.
    If both first and second furnace designed as a continuous furnace, the necessary residence times for the one or more first and second areas depending on the component length on the setting of the conveying speed and the interpretation of the respective kiln length can be realized. An influencing of the cycle time of the entire production line with heat treatment device and press for a subsequent press hardening is thus avoidable.
    In an alternative embodiment, the second furnace is a batch furnace, for example a chamber furnace.
    In a preferred embodiment, the treatment station has a device for rapid cooling of one or more second regions of the steel component. In an advantageous embodiment, the device has a nozzle for blowing the second part or regions of the steel component with a gaseous fluid, for example air or an inert gas, for example nitrogen. For this purpose, in an advantageous embodiment, the device has one or more nebulizing nozzles. By blowing with the gaseous fluid mixed with water, the heat removal from or from the second regions is increased.
    In a further embodiment, the second or the second regions are cooled via heat conduction, for example by contacting with a stamp or a plurality of punches, which has or have a significantly lower temperature than the steel component or. For this purpose, the stamp can be made of a good heat-conducting material and / or be cooled directly or indirectly. A combination of the types of cooling is conceivable.
    With the method according to the invention and the heat treatment apparatus according to the invention steel components with one or more first and / or second areas, which can also be complex formed, economically a corresponding temperature profile can be impressed as the different areas contour sharp very quickly to the necessary process temperatures can be brought.
    According to the invention it is possible with the method shown and with the heat treatment device according to the invention to set almost any number of second areas. The second or the second areas were never austenitized during the course of the process and, even after being pressed off, have low strength values similar to the original strengths of the untreated steel component. Also, the selected geometry of the sections is freely selectable. Dot or line areas are as well as e.g. large areas representable. The location of the areas is irrelevant. The second regions may be completely enclosed by first regions or located at the edge of the steel component. Even a full-surface treatment is conceivable. A special orientation of the steel component to the passage direction is not required for the purpose of the method according to the invention for the targeted component zone-specific heat treatment of a steel component. A limitation of the number of simultaneously treated steel components is possibly given by the press hardening tool or the conveying technique of the entire heat treatment apparatus. The application of the method to already preformed steel components is also possible. Due to the three-dimensionally shaped surfaces of already preformed steel components, there is only a greater constructive effort for the representation of the opposing surfaces.
    Furthermore, it is advantageous that even existing heat treatment systems can be adapted to the inventive method. For this purpose, in a conventional heat treatment device with only one oven behind this only the treatment station and the second oven must be installed. Depending on the design of the existing furnace, it is also possible to divide this, so that from the original one furnace, the first and the second furnace arise.
    Further advantages, features and expedient developments of the invention will become apparent from the dependent claims and the following description of preferred embodiments with reference to the figures.
    FIG. 1 shows a typical temperature curve during the heat treatment of a steel component with a first and a second area. FIG. 2 shows a thermal heat treatment apparatus according to the invention in one. FIG

    FIG. 1 shows a typical temperature curve during the heat treatment of a steel component 200 having a first region 210 and a second region 220 according to the inventive method. [0029] FIG. The steel component 200 is heated to a temperature below the AC3 temperature in the first furnace 110 during the residence time tn0 in the first furnace 110 according to the schematically indicated temperature run θ200, -ιιο. Subsequently, the steel component 200 is transferred to the treatment station 150 with a transfer time ti20. The steel component loses heat. In the treatment station, a second region 220 of the steel component 200 is rapidly cooled, wherein the second region 220 loses heat in accordance with the indicated curve θ22ο, ΐ5ο. The blowing ends after the treatment time tB has elapsed, which is only a few seconds, depending on the thickness of the steel component 200 and the size of the second region 220. In a first approximation, the treatment time tB is equal to the residence time t150 in the treatment station 150. The second area 220 has now reached the cooling stop temperature £ s. At the same time, the temperature of the first region 210 in the treatment station 150 has fallen in accordance with the plotted temperature profile θ210, ΐ5ο, wherein the first region 210 is not located in the region of the cooling device. After the lapse of the treatment time tB, the steel member 200 is transferred to the second furnace 130 during the transfer time t12i, further losing heat. In the second furnace 130, the temperature of the first region 210 of the steel component 200 changes according to the schematically drawn temperature profile θ2ιο, ΐ3ο during the residence time t130, i. the temperature of the first region 210 of the steel member 200 is heated to a temperature above the AC3 temperature. The temperature of the second region 220 of the steel component 200 increases according to the plotted temperature profile θ220, -ι30 during the dwell time t130, without reaching the AC3 temperature. The second furnace 130 has no special devices for different treatment of the various regions 210, 220. Only one furnace temperature, i. an essentially homoge- neous temerature in the entire interior of the second
    Furnace 130, which is above the Austenitisierungstemperatur AC3. Since the second region or regions have a significantly lower temperature than the first region (s) at the beginning of the residence time t130 in the second furnace 130 and both regions are heated in the same way in the second furnace 130, they also have a different temperature at the end of the residence time ti3o. The residence time ti30 of the steel component 200 in the second furnace 130 is dimensioned so that the first region or the first regions at the end of the residence time t130 have a temperature above the AC3 temperature, while the second and the second regions at this time the AC3 temperature not yet reached.
    Subsequently, the steel component can be transferred during a transfer time ti3i into a press-hardening tool 160, which is installed in a press, not shown. During the transfer time ti3i, the steel member 200 loses heat again, so that the temperature of the first region (s) may also fall below the AC3 temperature. However, this or these areas are essentially completely austenitized when they leave the second furnace 130, so that they undergo a transformation into hard martensitic structure by quenching for a residence time t16o in the press hardening train 160.
    Clearly contoured delimitations of the individual regions 210, 220 can be realized between the two regions 210, 220, and the distortion of the steel component 200 is minimized by the small temperature difference. Small spreads in the temperature level of the steel component 200 have an advantageous effect on further processing in the press-hardening tool 160. The necessary residence time ti30 of the steel component 200 in the second furnace 130 can be realized depending on the length of the steel component 200 via the adjustment of the conveying speed and the design of the length of the second furnace 130. Influencing the cycle time of the heat treatment device 100 is thus minimized, it can even be avoided altogether.
    FIG. 2 shows a heat treatment device 100 according to the invention in a 90 ° arrangement. The heat treatment device 100 has a loading station 101, via which steel components are fed to the first furnace 110. Furthermore, the heat treatment device 100, the treatment station 150 and arranged in the main flow direction D behind the second furnace 130. Next in the main flow direction D arranged behind it is a removal station 131, which is equipped with a positioning device (not shown). The main flow direction now bends substantially 90 ° to allow a press hardening tool 160 to follow in a press (not shown) in which the steel component 200 is press hardened. In the axial direction of the first furnace 110 and the second furnace 130, a container 161 is arranged, can be spent in the rejects. The first furnace 110 and the second furnace 120 are preferably designed in this arrangement as continuous furnaces, for example roller hearth furnaces.
    Fig. 3 shows a heat treatment apparatus 100 according to the invention in a straight arrangement. The heat treatment device 100 has a loading station 101, via which steel components are fed to the first furnace 110. Furthermore, the heat treatment device 100, the treatment station 150 and arranged in the main flow direction D behind the second furnace 130. Next in the main flow direction D arranged behind it is a removal station 131, which is equipped with a positioning device (not shown). Further, in a further straight main flow direction, a press hardening tool 160 follows in a press (not shown) in which the steel component 200 is press-hardened. At substantially 90 ° to the removal station 131, a container 161 is arranged, can be spent in the rejects. The first furnace 110 and the second furnace 120 are also preferably designed as continuous furnaces, for example roller hearth furnaces, in this arrangement.
    FIG. 4 shows a further variant of a heat treatment apparatus 100 according to the invention. The heat treatment apparatus 100 again has a loading station 101, via which steel components are supplied to the first furnace 110. The first oven 110 is at this
    Execution again preferably designed as a continuous furnace. Furthermore, the heat treatment apparatus 100 has the treatment station 150, which in this embodiment is combined with a removal station 131. The removal device 131 may, for example, have a gripping device (not shown). The removal station 131 removes the steel components 200 from the first furnace 110, for example, by means of the gripping device. The heat treatment with the cooling of the second or the second regions 220 is carried out and the steel components or the steel components 200 become substantially at 90 ° to the axis of the first Furnace 110 arranged second oven 130 inserts. This second furnace 130 is preferably provided in this embodiment as a chamber furnace, for example with a plurality of chambers. After expiration of the residence time t130 of the steel components 200 in the second furnace 130, the steel components 200 are removed from the second furnace 130 via the removal station 131 and inserted into an opposed press-hardening tool 160 installed in a press (not shown). For this purpose, the removal station 131 may have a positioning device (not shown). In the axial direction of the first furnace 110, a container 161 is arranged behind the removal station 131, can be spent in the rejects. The main flow direction D describes in this embodiment, a deflection of substantially 90 °. In this embodiment, no second positioning system for the treatment station 150 is required. Moreover, this embodiment is advantageous if there is insufficient space in the axial direction of the first furnace 110, for example in a production hall. The cooling of the second regions 220 of the steel component 200 in this embodiment can also take place between the removal station 131 and the second furnace 130, so that no stationary treatment station 150 is required. For example, a cooling device, for example a blowing nozzle, can be integrated into the gripping device. The removal device 131 ensures the transfer of the steel component 200 from the first furnace 110 into the second furnace 130 and into the press-hardening tool 160 or into the container 161.
    Also in this embodiment, the position of the press-hardening tool 160 and container 161 can be reversed, as seen in FIG. The main flow direction D in this embodiment describes two deflections of substantially 90 °.
    If the space for the installation of the heat treatment device is limited, offers a heat treatment apparatus according to FIG. 6: Compared to the embodiment shown in Fig. 4, the second furnace 130 is displaced in a second plane above the first furnace 110. Also in this embodiment, the cooling of the second regions 220 of the steel component 200 can also take place between the removal station 131 and the second furnace 130, so that no stationary treatment station 150 is required. Again, it is advantageous to run the first furnace 110 as a continuous furnace and the second furnace 120 as a chamber furnace, possibly with multiple chambers.
    Finally, in Fig. 7, a final embodiment of the heat treatment apparatus according to the invention is shown schematically. Compared to the embodiment shown in FIG. 6, the positions of the press-hardening tool 160 and the container 161 are reversed.
    The embodiments shown here are only examples of the present invention and therefore should not be understood as limiting.
