HEAT-INSULATING SLAG-FORMING MIXTURE Russian patent published in 2017 - IPC B22D7/10 B22D11/111 

FIELD: metallurgy.

SUBSTANCE: heat-insulating slag-forming mixture contains, wt %: ladle white slag produced by rail electric steel - 45-65 and organic additive - 35-55. Use of a mixture of husks of cereal crops - 50-60 and sawdust of hardwood species - 40-50 as organic additive results in an increase of the thickness of the layer of the heat-insulating mixture and formation of a liquid slag on the surface of the slag-forming material from the slag-forming material with a high heat-insulating capacity.

EFFECT: reduction of rejects associated with temperature changes and solidification of steel in the ladle, reduction of heat losses during casting of steel and increase in the seriality of the cast steel.
