PROCESS FOR PRODUCING FOUNDRY IRON.

摘要

A submerged arc furnace (10) produces foundry iron from scrap iron and steel sources where little or no slag is produced. Scrap iron or steel is fed into the submerged arc furnace (10) with a source of silica and a carbonaceous reducing agent. The scrap iron and steel is melted while simultaneously smelting the silica in the presence of the carbonaceous reducing agent. The amount of the silica source and carbonaceous reducing agent are added in an amount to selectively control the silicon and carbon content of the resulting foundry iron.
