When steel is added to manganese iron alloy, it can be better reduced, and it can also enhance the toughness, hardness, strength, and elasticity of steel. Silicon is also an effective graphitizing medium, which can turn the carbon in cast iron into free graphitic carbon. Standard gray cast iron and ductile cast iron need to add at least 4% silicon. Most of the manganese and silicon elements are added to the molten steel in the form of ferromanganese, silicomanganese, and ferrosilicon.

Silicon calcium manganese deoxygenation has strong ability to deoxygenate and remove inclusions, low melting point, fast melting speed, good fluidity, and can effectively shorten refining time and reduce refining power consumption. No smoke or flames during use, with good safety and environmental friendliness.  With strong deoxidation and desulfurization capabilities, it effectively improves the fluidity of molten steel, purifies it, reduces impurities in steel, significantly reduces steelmaking costs, and improves economic benefits.
