compact-MATERIAL FOR ladle treatment of cast iron

摘要

The invention relates to the ferrous metallurgy. The compact material for ladle treatment of cast iron is claimed, which consists of powder core-filler placed in a steel casing, which includes fining slag mixture containing burned dolomite (BDM), iron-graphite waste (IGW) of the blast-furnace production – "refining foam" and aluminosilicate phase of screening chamotte refractory (SCR) at the following ratio of components: BDM:IGW:SCR=1:(1-3):(1-2). The mixture should correspond to the stoichiometric composition of eutectic aluminum silicate 3CaOMgOAlO3SiO. Technical result is high efficiency of liquid cast iron processing and a low value of the new material.
