It uses coke, steel scrap and silica as raw materials, refined in a furnace to produce ferro silicon. Ferro silicon sometimes can be more used in some low alloy structural steel, spring steel and bearing steel as an alloying element addition agent, or also used as reductant in some chemical industry and ferroalloy production industry.People make them to the silicon iron ball because of the extensive use of ferro silicon, which can make their particle size more uniform mesh.It can save a lot of fuel in use, make the burning time more long, speed up the melting speed and uniform distribution. Ferro silicon is widely used in some pig iron smelting industry production and common casting which is one of the best materials. Silicon iron is mainly used in steel slag.It improve Output , speeding up the production speed and also more used in common casting industry.
