Description of Ferrosilicon Nitride:
Ferro Silicon Nitride is a mixture of Si3N4 as the main component, accompanied by free iron, non-nitride ferrosilicon and a small amount of other components. Ferrosilicon nitride is divided into two types according to its use: ferrosilicon nitride for refractory materials and ferrosilicon nitride for steelmaking. Ferro-silicon nitride for refractory materials is an off-white or dark brown powder, and ferro-silicon nitride for steel-making is an off-white granular material.
Ferrosilicon nitride is mainly used in the plugging mud of large blast furnaces, and a small amount is used in iron trench materials or other amorphous refractory materials; Granular ferrosilicon nitride is mainly used for oriented silicon steel or other steel grades that use nitrides to improve strength.
Technical Parameter of Ferrosilicon Nitride:
|Ordinary ferrosilicon nitride||NPFeSiN-A||75~80||49~51||30~32||13~15||≤1.5||≤1.0||≤0.1|
|Stable ferrosilicon nitride||NWFeSiN||68~75||45~48||27~30||11~14|
|Specification: the particle size of ordinary ferrosilicon nitride is 200 mesh, that of stable ferrosilicon nitride is 325 mesh, and the passing rate is 90%|
