![]() Water-cooled hood cover for electric furnace with three electrodes
专利摘要:
A cover for a metallurgical vessel has a top part formed as a flat, generally circular, and normally horizontal array of tubes having an outer edge and forming a plurality of vertically throughgoing passages. These tubes extend mainly angularly of the center of the array. Respective pluralities of annular tubes at and extending around the passages are connected with each other at the center and with the tubes of the flat array. This top part has a skirt formed as an annular array of generally vertical tubes extending downwardly from the outer edge and connected with the tubes of the flat array. Respective partially circularly annular collars at the passages on the flat array have inwardly directed closely juxtaposed ends. The collars and tubes are connected together as a rigid assembly. A coolant is circulated through the tubes. 公开号:SU1194294A3 申请号:SU823516221 申请日:1982-11-26 公开日:1985-11-23 发明作者:Кульманн Герберт 申请人:Сидепал Са Сосьете Эндюстриель Де Партисипасьон Люксембуржуаз (Фирма); IPC主号:
专利说明:
V. one This invention relates to ferrous metallurgy, in particular, to the design of water-cooled lids for electric furnaces. The aim of the invention is to increase the service life of the cover, simplifying its design. FIG. 1 shows the proposed cover, top view; in fig. 2 is a section A-A in FIG. one. The cover contains an outer support ring 1, an inner support ring 2, three round holes 3 and a bottom 4.. . The bottom 4 has cooling pipes 5 located adjacent to each other in the direction of the circumference. They can be located in areas instead of (1O the whole circumference. The outer support ring 1 consists of cooling pipes 6 vertically located next to each other. All cooling pipes 5 and 6 are combined by means of caps 7 into a meander cooling system. Three holes 3 are offset relative to each other by 120. In addition, the proposed cap may have holes 8, serving as 94294 loading the charge or release of finished products. The inner support ring .2 is made of intercooled pipes 9 arranged one above the other in the direction of the circumference of the openings 3 directly around each opening. The cooling tubes 9 are combined in the center of the 10 bottom 4 and at the same time 10 form the carrier star 11, which increases the strength of the structure. . . To the inner bearing ring 2, upper flanges 12 are welded on the outside, fitted with axes 13, which are 5 between the holes 3. Inner support ring 2, cooling pipes 5 of the bottom 4 and the outer supports (loe ring are interconnected and form a self-supporting cap. 20 This can be accomplished with fasteners 14. The cooling tubes 5, 6 and 9 of all the nodes of the bell cover are integrated with each other using spacers 25 and leaf strips 15. The invention makes it possible to increase the service life of a roof while at the same time simplifying its construction. /} -BUT FIG. 2
