METHOD OF STEEL CONTINUOUS CASTING Russian patent published in 2009 - IPC B22D11/00 

FIELD: metallurgy.

SUBSTANCE: into tundish ladle it is fed steel from sequentially supplied casting ladles. On steel reflector in tundish ladle it is add slagging mixture with consumption 5.2-6.1 kg/t of steel in tundish ladle and organic heat insulating mixture with consumption 1.8-2.1 kg/t of steel in tundish ladle. Slagging mixture includes (wt %): dust from ferrosilicon production (36.0-38.0), dust from aluminium production (20.0-22.0), dust from lime production (41.0-43.0). Heat insulating mixture includes (wt %): grain crops husks (80.0-98.9), saw dust (1.0-15), mineral constituents (0.1-5.0). With casting ladle changing into tundish ladle it is add slagging mixture with consumption till 2.4 kg/t of steel in tundish ladle and organic heat insulating mixture with consumption till 1.1 kg/t of steel in tundish ladle.

EFFECT: efficient use of slagging mixture, heat loss enhancement with steel teeming, improvement of casted steel.
