10-100mm Si3n4 Ferrosilicon Nitride
Ferro silicon nitride is a ferroalloy material mainly composed of Si3N4,accompanied by free iron,non-silicon nitride,and a small number of other components.Commercial ferrosilicon nitride for refractory is an off-white or brown powder,while steel-making ferrosilicon nitride is off-white granular. Powdered ferrosilicon nitride is mainly used in the tap hole of large blast furnaces,and a small amount is used in iron runner materials or other unshaped refractory materials. Granular ferrosilicon nitride is mainly used in silicon-oriented steel or other steels (Such as HRB400 rebar) that use nitrides to improve strength.
Description
Description
Ferrosilicon nitride is a mixture of Si3N4 as the main component, with free iron, unferrosilicon nitride and a small amount of other components. Commercial ferrosilicon nitride for refractory use is a grayish white (or tawny) powder, and ferrosilicon nitride for steelmaking is a grayish white granular substance.
