METAL CONTINUOUS CASTING METHOD Russian patent published in 2000 - IPC

FIELD: foundry, namely casting alloys containing scab forming elements, for example aluminium bronze. SUBSTANCE: in dead-bottom immersible sleeve with lateral lower and upper openings metal is subjected to refining by flux then fed in mold under bath level. Before immersing sleeve into bath, protective coat is applied onto bath surface, flux is supplied to sleeve for diluting slag and then it is removed through lower openings of sleeve. After immersing sleeve on surface of metal column in it refining flux is applied until level of upper openings. According to casting process openings are periodically cleaned by mechanical way; slag collected at level higher than said openings is removed and flux layer in sleeve is partially modified. Best conditions are achieved at ratio of mass of metal column in sleeve to mass casting rate in range 2-10 and at relation of thickness of flux layer to height of metal column in sleeve in range 0.2-0.8. EFFECT: enhanced metal purification from scab, less loss of metal yield. 6 cl, 1 tbl, 13 ex
