    The invention relates to a device for continuous heat treatment of a long metal product, in particular wire or steel strips. 5
    A known installation for heat treatment of long metal material containing an unwinding device; heating chamber, cooling bath and winding drums. The heating of the Yu wire to the patenting temperature in this installation occurs through radiation til.
    The disadvantage of this installation is that, for large wire diameters, relatively high
    long metal material, in particular wire, containing successively arranged heating and quenching baths with liquid metal, connected to a transformer [2 3. A disadvantage of the known installation is that it requires a significant amount of energy to heat a preheating bath. In addition, the thermal energy introduced by the strongly heated wire into the quenching bath must be diverted all the time, which entails the need for further energy and technical costs. Electric patenting uses more energy for operating bathtubs than for self-heating by wire resistance.
    The purpose of the invention is the reduction of energy costs. .
    This goal is achieved by the fact that in the known installation for continuous heat treatment, containing successively arranged heating and quenching baths with liquid metal, connected to a transformer, the heating bath is installed partially20 essence to the proposed is the installation for continuous heat treatment but immersed in the quenching, while its body is made electrically insulated from a material having a large heat conductive 1b with respect to liquid metal.
    In FIG. 1 shows the proposed installation with a symmetrical arrangement in relation to each other pre-heating and quenching baths;
    in FIG. 2 - the same with quenching! long tub.
    Installation (FIG. I) contains installation 993826 4
    450-500 ° C, then this wire passes through the high-heating section 10, where it quickly reaches a temperature of 1000 ° C. During subsequent passage through the quenching bath 2, the wire is cooled to 500 ° C and maintained at this temperature for about 20 seconds to form the desired sorbitol structure,
    The quenching bath 2 is equipped with a pump 13 which can be a conventional apparatus, which is suitable for pre-heating 1 and quenching 2 baths. The shell 3 of the pre-heating bath is mounted on supports 4 and is provided with internal insulation 5, which electrically isolates the pre-heating bath 1 from the quenching 2 and allows only the transfer of thermal energy.
    The sheath 3 of the preheating bath, as well as the sheath 6 of the quenching bath, is connected to the secondary winding 7 of the transformer 8. The metal baths 1 and 2 thereby act as electric contact baths for the wire 9 drawn in the direction of the arrow. The dashed section of the wire Yu corresponds to the jg section high heating, on which the wire quickly heats up to approximately 10.00 ° C.
    Inside the quenching bath 2 there is a combined heating - cooling device II, which is activated when the unit is started, as well as when removing excessive amounts of energy.
    After passing through the pre-heater 40 but the heating bath I and the high heating section 10, the wire passes the quenching bath 2 in the opposite direction and the cooling section 12 cooled by the flowing air.
    In the second embodiment of the proposed installation (Fig. 2), a pump 13 is provided for transferring thermal energy to the immediately adjacent region to the preheating bath. The supply of wires is carried out continuously in the same direction, as a result of which the pump unit 13 acts here in the direction opposite to the movement of the wire.
    Installation works as follows.
    The pre-heating bath I heats the passing wire until the liquid metal circulates in the metal baths. The continuous circulation of liquid metal in the quenching bath 2 serves, on the one hand, to transfer thermal energy to the immediately adjacent region to the bottom of the preheating bath 1 and, on the other hand, to prevent overheating phenomena in the aeon of the inlet and wire.
    The energy required for strong heating and austenitization of the wire, which 25 during the subsequent sorbitization is almost completely transferred to the quenching bath 2, is used to heat the preheating bath I, since the latter is almost completely washed by the liquid metal in the quenching bath.
    The quenching bath 2 is equipped with a combined heating-cooling device II to create the necessary temperature ratios at the start of the installation, and, accordingly, to divert possible excessive amounts of thermal energy.
    Using the proposed installation, it is possible to continuously maintain a pre-heating bath 1 without a significant additional supply of energy at a satisfactory high temperature. In this case, it is achieved that the conditions necessary for the formation of the desired sorbitol structure are maintained in the quenching bath 2, namely, a homogeneous temperature of 500-550 ° C. In addition, the thermal energy transferred to the quenching bath 2 by a highly heated wire is used expediently. In the proposed installation, compared with the known energy savings reaches up to 5O% "
    If the dimensions of the quenching bath 2 are twice as large as those of the preheating bath 1, then it is possible to provide for the quenching bath to be made in the form that is as long as possible. In the consistent development of this design principle, it is also possible to provide for the separation, on the one hand, of the quenching bath into 5 two sections with a jumper or, on the other hand, the installation of two separated exchange baths, one of which contains a pre-heating bath and connected to the other by proton 10 channels. The shells of the baths are made of steel, as appropriate. It is possible when installing the shell of the preheating bath to install an insulating layer in the form of a binder 15. The construction in the form of SENVIG is also possible, in which an insulating layer predominantly made of ceramic material is included between two steel shells. 20
