NONMETALLICS AND QUALITY OF ELECTRIC STEEL 20 ГЛ, SMELTED WITH USE OF CSiC-BRIQUETTES INSTEAD OF PIG-IRON

摘要

Materials of nonmetallics makeup exploration in steel 20ГЛ, smelted in 25-tons arc electric furnaces on freshen mix material with use carbon-silicon carbide briquettes on a cement binding (CSiC-briquettes) instead of an expensive steel-making iron are submitted
