METALLURGICAL VESSEL WITH METALLIC ELECTRODE HAVING READILY REPLACEABLE WEAR PART

摘要

A metallurgical vessel (10) includes at least one metallic electrode (20) fastened thereto having a chamber within the vessel (10) for holding a melt (19) and having a bottom surface, a shell (14) abutting the bottom surface, and a flanged tube (31) arranged on the shell (14) with the flanged tube (31) having a flanged surface (32). The electrode (20) is disposed coaxially with respect to the flanged tube (31) and is formed by first and second bars (21, 22) connectable to one another. The first bar (21) has the top face positioned proximate to the bottom surface of the chamber and penetrates the vessel (10) for contact with the melt. The second bar (22) is positioned against the bottom face of the first bar (21) and extends out from the vessel (10), the first bar having a should region (23) positioned annularly thereabout adapted to contact and lean against the flanged surface (32) of the flanged tube (31). A coolant provision and discharge device provide coolant to the second bar (22) through a coolant feed line (51) and a discharge line (53) and a current feed device provides current to the electrode. A hold-down mechanism (33) attaches the current feed device, the coolant feed line (51) and the discharge line (53) to the flanged tube (31).
