APPARATUS FOR VACUUM TREATMENT OF LIQUID METAL Russian patent published in 2001 - IPC

FIELD: ferrous metallurgy, namely out-of-furnace vacuum refining of melt metal. SUBSTANCE: all aggregates necessary for realizing process of steel vacuumizing are combined in single technological module mounted on portal having mechanism for vertical and horizontal motions. Common sluice chamber is in the form of cylinder or polygonal prism divided by mutually insulated sections whose number is equal to that of separate technological aggregates. Each section is provided with sealed door; inside section aggregate is arranged in such a way that it is possible to remove it through door port of section. Sealing device is placed in upper portion of cover of vacuum chamber in such a way that portal rests upon it. It provides vacuum sealing without additional mounting attachments. EFFECT: enhanced operational reliability, simplified maintenance and operation, reduced size and metal consumption, enlarged manufacturing possibilities of apparatus. 5 dwg
