In the steelmaking industry for Deoxidizer and alloying agent. In order to obtain chemical composition of qualified steel and steel guarantee the quality, steel-making in the final stages of the need for deoxy, silicon and oxygen chemical affinity between the large, steel-making is thus ferrosilicon Deoxidizer for more precipitation and proliferation Deoxy. Add in a certain amount of steel in silicon, can significantly increase the strength of steel, hardness and elasticity, thus the structural steel smelting (Hanbaoyufang Silicon 0.40-1.75%), tool steel (including SiO. 30-1.8%), spring Steel (including SiO. 40-2.8%) and transformers with silicon steel (Silicon 2.81-4.8 per cent), also as a ferrosilicon alloys agents.

In addition, the steel-making industry, use of ferrosilicon powder en-burning at a high temperature heat that can emit large number of characteristics, often as the fever for the use of steel ingot apparatus to improve the quality and recovery of steel ingot.
