Description

description: 　　Ferro Silicon Nitride is an alloy additive in smelting of cold-rolling orientated silicon steel. Its addition increases the steel strength of ambient low temperature and improves corrosion-resistance , thermal shock resistance and abrasion resistance abilities of steels. 　　Ferro Silicon Nitride is new excellent refractory materials, which can instead of expensive Silicon Nitride, used for no water gunning materials in steel plant.
