SLAG-FORMING MIXTURE FOR STEEL CONTINUOUS CASTING Russian patent published in 2010 - IPC B22D11/111 

FIELD: metallurgy.

SUBSTANCE: invention relates to ferrous metallurgy. Mixture contains following components in wt %: carbon-bearing ingredient 5-10, fluorine-containing ingredient 10-20, synthetic fused slag-forming ingredient is the rest. In the capacity of slag-forming oxide basis it is used synthetic fused slag-forming ingredient of system CaO-SiO₂-Na₂O, containing CaO 30-45%, SiO₂ 40-65% and Na₂O 5-15% at ratio CaO/SiO₂ 0.45-0.95.

EFFECT: there is achieved reduction of total content of moisture in mixture, increasing of stream assimilation relative to floating from steel aluminium oxides.
