- Brand Name:-
ferro silicon nitride powder is applicable to stainless steel smelting, special alloy steel smelting, oriented silicon steel smelting
and other casting industries.
As a new type of
refractory material, it is applied in the metallurgical field, such as metallurgical furnace body, furnace mouth seal, ironmaking furnace outlet, iron hook amorphous material and nitrogen
additive in the steelmaking industry.
Silicon nitride
material can be used as abrasive material for abrasive tool manufacturing, and can also be used in chemical fields such as acid resistance, alkali resistance and corrosion resistance.
In terms of steelmaking, granular ferro silicon nitride is mainly used in the production of oriented silicon steel at the initial stage, and it can stably supplement a
certain amount of nitrogen for molten steel.
