FOUNDRY CRUCIBLE Russian patent published in 2002 - IPC

FIELD: metallurgy. SUBSTANCE: invention is related to melting and casting of refractory reaction metals in lining furnaces with plasma or electron beam heating. In foundry crucible discharge unit is separable and has shape of discharge spout made of same metal as melted metal, it includes split attachment devices and mounting holes. Temperature of discharge spout is controlled by plasma or electron beam heater. Foundry crucible with separable discharge unit makes it feasible to simplify considerably metal discharge operations, to raise productivity of furnaces, to exclude technological operations for removal of metal skull from discharge units, to simplify process of removal of slag hardened on walls of foundry crucible. EFFECT: higher productivity of melting furnaces. 2 cl, 1 dwg
