Rongsheng Refractories Group
Powdered ferrosilicon nitride is mainly used in cement slurry of large blast furnaces, and a small amount is used in iron channel materials or other shapeless refractory materials; granular ferrosilicon nitride is mainly used in oriented silicon steel or other materials, which use nitrides to increase the strength of steel.
