PROCESS AND BRIQUETTE FOR HOMOGENIZING MOLTEN CAST IRON

A method of producing homogeneous cast-iron melts from a heterogeneous charge containing a proportion of steel scrap of up to very high amount as well as other ordinary charge components, such as pig iron, broken castings, recycle material and furnace additives, characterized by the fact that by the addition of compacts of silicon carbide or other alloying substances and/or ordinary charge components containing slag-forming admixtures from the ternary system 8-18% CaO-10-40% SiO2-2-16% Al2O3 which contain additions of hydrocarbon and/or hydrocarbon-nitrogen compounds, a reductive furnace atmosphere and a limiting of suboxide-containing primary slags, a practically loss-free carburization and silicification as well as a favorable condition of nucleation of the homogenized melt is brought about, as well as compacts for carrying out the said method, are disclosed.
