It can replace ferrosilicon, silicon carbide, recarburizer, reduce the amount of deoxidizer, used in converter smelting deoxidation alloying process, the effect is stable, steel chemical composition, mechanical properties and internal control quality are better than traditional processes. Its characteristics: improve the quality of molten steel, improve product quality, improve product new capabilities, reduce the amount of alloy added, reduce steelmaking costs, and increase economic benefits.
