    (54) DEVICE FOR HEATING MELT
    one
    The invention relates to devices for heating a melt with an inert gas, for example, in zinc baths, tinning, for enamel coating. In this case, the inert gas used for heating s is introduced into the bath melt through vertical shafts located on the longitudinal and / or transverse sides of the bath or vat, is bubbled through the heated melt and is discharged through the outlet channel over the shafts.
    A device for heating a melt is known, comprising a bath for placing the melt, a gas circulation system of 1 d gas, gas supply pipes, and a wall located above the pipes along the edges of the bath and forming a shaft having a portion perpendicular to the inner space of the bath C . 20
    Most of the melts, for example, to coat products with zinc, with increasing heating temperature increases its aggressiveness with respect to the metal-immersed 25 INERTNSH GAS
    parts, which reduces their service life. In this case, if the pipes in the side shafts are made of metal, then their service life is very short. The ceramic tubes immersed in the bath must have a considerable wall thickness in order to provide the required strength, since the high specific gravity melt is in constant motion due to the inert gas passing through it. Thick pipes reduce the free cross-section in the side shafts, so that the circulation that occurs in the vertical parallel planes is disturbed. This leads to a limitation of heat transfer between the hot inert gas and the melt.
    The purpose of the invention is to increase the durability of the device.

    Claims (3)
    [1]
    This goal is achieved by the fact that in a device for heating a melt with an inert gas containing a bath for melt, a gas circulation system, gas supply pipes, a side wall located above the pipes and forming a shaft with bath walls, a hole is made in the side wall ), the upper end of which is connected to the gas supply pipes, the spline separating the wall into two parts, one of which, facing the center of the bath, has an extension. The exit hole in the side wall is directed to the middle of the mine. Partitions are installed at the lower end of the slot to separate the gas flow. On the part of the wall, which is turned to the middle of the mine, there is a rib or a run. The rib or protrusion is open at the bottom of the wall. On the part of the wall facing the center of the bath, there is a rib or a protrusion for deflecting the gas flow. Figure 1 shows a bath with side longitudinal shafts, a perspective view; figure 2 - section of figure 1 ;. in FIG. 3, the wall of the shaft between the middle of the bath and the shaft, an embodiment; in fig. and 5 is the same cross section. Bath 1 serves to galvanize a ribbon-like metal product. The bath is made of the bottom 2 and two side machines 3 and 4 with the lining 5 of a ceramic material. The flanges 6 of the walls 3 and the metal part 7 are mounted with a ceramic facing 8 of the nozzle 9. The bottom 2, as well as the walls 3 and part 7, form an open top of the container in which the product is processed. The upper section of the walls 3 and with their facings 5i as well as the metal parts 7 with their facings 8 form the outer wall of the vertical shaft 10 on each side of the tank, which is limited to the middle of the bath by the vertical ceramic wall 11 of the nozzle 9 and open up, the vertical wall 11 passes at the top of the inclined wall 12, the continuation of which forms the horizontal wall 13 of the nozzle 9. This wall, together with the horizontal internal wall 1, forms the restriction of the outlet channel 15, into which the exhaust pipe 16 enters, through which Inert gas is withdrawn from the device and supplied to a heater (not shown), from which 4 heated inert gas is supplied to pipeline 17. This pipeline enters distribution chamber 18, and inert gas from pipe 15 is fed through vertical opening 20 in the wall 11 of the shaft 10. Through the hole 20 into which the pipeline 17 can directly enter, the ceramic wall 11 of the shaft 10 is divided into a portion 21 of the cross section facing the middle of the bath and part 22 distant from the middle of the bath. The part 21 of the wall 11 distant from the middle of the bath is made down longer than the section 22 of the cross section of the wall facing the middle of the shaft. As a result, the gas flow from the hole 20 is directed in the direction of the arrow 23 (Fig. 2) to the middle of the shaft 10, where the gas flow rises up and enters the discharge channel 15 and the pipe 16. The heat exchange and the action of the mammut pump are greatly increased due to that the gas stream is divided into bubbles. For this, a section 22 of the cross section at its lower section, which is turned towards the middle of the shaft. The end has a rib or protrusion directed inside the shaft, by which the gas flow is cut off at the free edge 2k of the rib or bulge 25 and divided into separate small bubbles to provide increased circulation intensity of the melt in the shaft 10 and heat exchange between the inert gas and the melt in the mine. The interior of the shaft 10 remains free to circulate the melt. To ensure gas flow to the middle of the shaft, the portion 21 of the cross section of the bath wall at its lower end remote from the center of the shaft can be provided with an edge 26 directed toward the middle of the shaft. To increase the stability of the wall 11 relative to the melt circulating in the mines 10, instead of one hole 20 a row of holes 27 is provided (Fig. 5), and this row at its lower end has the same embodiment as. cross-sectional wall sections 21 and 22. Instead of a row of holes 27, the slot can be divided by ribs 28, which as separate parts 58 can be connected to parts 21 and 22 or made in one piece with part 21 and 22 of the cross section of the wall. Additionally, or in contrast to having a hole 20 or a row of holes 27, a slot or a row of holes may be provided in the wall 11 in the ceramic linings 5 and 8 of the side walls 3, respectively, of the metal parts 7. At the same time, the pipes 17 and 19 are connected with this slot or a series of holes, while the branch duct 15 is configured as shown in FIG. Claim 1. Device for heating the melt with an inert gas, containing a bath for melting gas circulation system, gas supply pipes, a side wall located above the pipes and forming a shaft with bath walls, characterized in that in order to increase the service life elements of the device, which are located in aggressive melts, have a hole (slot) in the side wall, the upper end of which is connected to gas supply pipes, and the slot divides the seal into two parts, one of which, facing the center of the bath, has dlinenie.
