ABSTRACT:
A metallurgical container for the inductive treatment of metals comprises an inner lining of refractory material and a generally tubular enclosure comprising an upper annular casing surrounding the upper open end of the inner lining, a lower annular casing surrounding the bottom of said container, and a plurality of circumferentially spaced metallic tie rods extend parallel to each other through a median heating zone of the container. A plurality of connecting elements respectively extending through openings in the bottom wall of the upper casing and the top wall of the lower casing, electrically insulated from those walls, tightly connect opposite ends of the tie rods to each wall. The tie rods and the connecting elements are formed with coaxial channels for the passage of cooling fluid therethrough which is fed into one of the casings and discharged from the other.
The container according to the present invention permits powerful inductive treatment of metal and metal alloys, especially steel.
