Product Description

Ferro silicon

Product description

(1) Used as deoxidizer and alloying agents in the steel industry. In order to obtain qualified chemical composition and guarantee the quality of steel, in the last stage of the steel must be deoxi- dized. The chemical affinity between silicon and oxygen is very large,Thus ferrosilicon is strong deoxi- dizer used in sedimentation and diffusion deoxidation of steel-making. Add a certain amount of silicon in the steel, can significantly improve the strength, hardness and elasticity of steel.

(2) Used as a nucleating agent and spheroidizing agent in the iron industry. Cast iron is a kind of important modern industrial metal materials, It is much cheaper than steel, easily to melt refining, with excellent casting performance and seismic capacity is much better than steel. Especially the nodular cast iron,Its mechanical properties at or near the mechanical properties of steel. Add a certain amount of silicon in cast iron can prevent iron in formation, promote the precipitation of graphite and carbide spheroidizing. Thus in nodular iron production, ferrosilicon is a kind of important inoculants ( Help separate out graphite)and spheroidizing agent.
