METHOD OF CONTINUOUS CASTING OF INGOTS Russian patent published in 1995 - IPC

FIELD: foundry engineering. SUBSTANCE: metal is fed into crystallizer from auxiliary ladle through immersion casting nozzle. Excessive pressure chamber on metal meniscus in crystallizer is equal to ferrostatic pressure of liquid metal column in a space from metal meniscus in crystallizer to its meniscus in auxiliary ladle. Ingot is drawn out of crystallizer and crystallizer is set in reciprocating motion. Slag mixture of unchanged thickness is fed into excessive pressure chamber in the process of casting. Metal is fed into crystallizer at linear velocity of 2,0-25,0 of volume of ingot drawing linear velocity. Slag mixture is fed into excessive pressure chamber under pressure not less than ferrostatic pressure of metal column over its meniscus in crystallizer. Volume of excessive pressure chamber is changed in the process of casting proportionally to crystallizer swing. EFFECT: enhanced quality.
