Electroslag furnace

#The present invention relates to equipment to be used in the electric metallurgy, and more particularly, to electroslag furnaces.

#The invention may be used for remelting consumable electrodes under a layer of liquid slag and for producing high-grade metal ingots and alloys in ferrous and non-ferrous metallurgy.

#Widely known in the art are electroslag furnaces comprising a column in the form of an all-welded vertical box-shaped rectangular structure having internal ridges and a shaft for accommodating a balance weight of an electrode holder carriage.

#The invention will now be described with reference to a specific embodiment thereof illustrated in the accompanying drawings, in which:

#FIG. 1 diagrammatically shows a side-elevational view, partly in cross-section, of the electroslag furnace according to the invention, wherein the column is provided with an even number of supports and current supply cables and cooling system hoses extend in the space therebetween.

#FIG. 2 is a sectional view taken along the line II--II in FIG. 1;

#The electroslag furnace according to the invention (FIGS. 1,2) comprises a column 1 which is made in the form of a all-welded rectangular section box-shaped structure with or without internal ridges. At the bottom portion, the end of the column 1 terminates in a bottom flange 2.

#A flange 3 (similar to the bottom flange 2) is bolted or welded to the bottom flange 2 of the column 1, and four supports 4 (FIG. 3), e.g., of tubular shape are rigidly secured to the flange 3. Depending on the size and weight of the electroslag furnace, the flange 3 (FIGS. 1,2) may be provided with two supports 5 (FIG. 4) or with a different even number of supports.

#Each support 4 (FIGS. 1, 2 and 3) has a base 6 comprising a flange or a welded frame and having holes 7 for fastening to a foundatin.
