Abstract

See full text

Silicon slags, which is a by-product of metallic silicon mill during producing metallurgical grade silicon, solar cell grade silicon and Ferro-silicon alloy. are processed according to the invention to small lumps and briquettes, being excellent deoxidizer for cast iron and steel in order to avoid either costly regeneration for the recovering of the valuable components or the total dumping of said silicon slags. The cost of iron and steelmaking can be reduced significantly. As an additional advantage, the particles of silicon slag in molten steel can absorb the tiny oxides from the deoxidizing reaction and purify the molten steel more quickly.
