    Melting furnace, especially an arc melting furnace, in which the furnace wall contains at least one water cooling box welded of steel plate and disposed above the melt level, whose surface facing the furnace interior is provided with projections which facilitate the adhesion of a refractory protective layer formed on this surface, wherein the wall of the water cooling box, which faces the furnace interior, has a thickness of at least 15 mm, the projections are formed of profile irons, and a refractory composition applied beforehand serves as the refractory protective layer.

    专利说明:

    The invention relates to metallurgy, in particular to an electric arc melting furnace, in which the walls contain at least one boxed water REFRIGERATOR placed above the level of the melt; A known smelting furnace, in order to prolong the service life of the walls of which, a water-fridge welded from steel sheets is embedded in the furnace wall behind the brick lining, by means of which a brick lining 1 is attached to the wall. However, due to the strong heating of the internal surfaces covered with the water cooler and because of the cooling effect on their outer surfaces, there is a danger that the bricks will deform and burst so that the open surfaces of the water cooler will be exposed to electric radiation. metrically arcs of the furnace. This leads to the fact that cracks appear in the wall of the water cooler, which leads to the release of cooling water and the danger of an explosion if it comes into contact with hot metal. The purpose of the invention is to reliably operate. To achieve the goal, the furnace is provided with a flange installed between the refrigerator and the underlying part of the furnace, the inner edge of which extends beyond the inner surface of the refrigerator towards the space of the furnace. The inner wall of the refrigerator may be located outside the outer surface of the underlying bath furnace. The inner wall of the refrigerator may lie in line with the outer surface of the underlying bath furnace. FIG. 1 shows an electric arc, melting py4, transverse p-cut (section A-A in FIG. 2); in FIG. 2, section BB in FIG. 1 (part of the longitudinal section); in fig. 3 and 4 are parts of the longitudinal sections of two subsequent versions of the melting furnace. The melting furnace contains a bottom-shaped part 1 made of refractory bricks, the edge 2 of which is approximately 30-40 cm higher than the maximum level of the melt 3. A removable wall 4 of the furnace is mounted on the edge of the lower part of the furnace in a slightly displaced position.
    The furnace wall consists of a large number of water coolers 5, which are made in the form of elements having the form of hollow sectors, and are equipped with nozzles 6 and 7, respectively, for separate cooling water supply. ОЕО) Outer surfaces of water coolers, supplied to the internal cavity of the furnace, are provided with protrusions, which, on the one hand, hold the Pre-applied refractory mass 8 and, on the other hand, with local damage to this refractory mass, scatter the scattering slag flying away, thereby form a fireproof protective layer. To prevent water from leaving the coolers in the melt zone, the furnace is provided with a flange 9 installed between the cooler and the underlying portion of the kiln, the inner edge of which extends beyond the inner surface of the cooler in the direction of the kiln space. The furnace furnace is also equipped with three electrodes 10.
    The joint between the water coolers and the bottom edge on the side of the internal cavity of the furnace is sealed with a refractory mass 11 (Fig. 2).
    In the embodiment shown in FIG. In the third embodiment, a hollow annular water cooler 5 is provided, which by means of the flange 9 is shifted further outward than in the exemplary embodiment of FIG. 2, relative to the lower edge 2 of the furnace below. The upper edge of the flange is obliquely upward and encased in a sealing joint of a refractory mass 11.
     The embodiment of FIG. 4 is basically different from the embodiment in FIG. 3 in that the flange 9 is made in the form of a gutter.
    On the annular flange 12 of the lower part 1 of the furnace there is a supporting structure 13 for water coolers 5 made in the form of sectors. The supporting structure consists of an annular flange 15 strengthened by a stiffener 14, which is spaced at certain distances from each other along the periphery on the periphery 16. On the holders there are two hollow profiles 17 and 18, which serve to supply the cooling water to the individual water coolers 5. The water chillers 5 in the form of hollow sectors on the upper edge have an outward-facing direction. a flange 19, with which they rest on the outer structure. The water flowing downward on the inside of the refrigerator is trapped by the annular flange 9 and is directed outwards.
    In the Examples of execution in the axial direction only one water cooler is provided, but there may also be several refrigerators stacked one above the other. In this case, the joints or flanges between water coolers located one above the other can be designed in such a way that they will catch the water flowing down the inner wall and divert it to the outside.
