Silicon Slag Iron
Products Description
Silicon Slag Iron is an industrial by-product generated during the smelting of ferro silicon alloys, combining residual silicon (45%-65%) with iron (5%-17%) in a dark gray to black granular/block form. It delivers reliable deoxidation and alloying performance in steelmaking and foundry at 30-50% lower cost than pure FeSi 75%.
