Silicon iron nitride stands out as an indispensable additive in the production of cold rolled unidirectional silicon steel sheets. This remarkable product enhances normal temperature and low temperature strength, and significantly boosts corrosion resistance. When added to metal melts, it offers unparalleled thermal shock resistance and corrosion protection. Iron silicon nitride emerges as a new-generation, high-quality refractory raw material, ideal for anhydrous mud in large blast furnaces. It features excellent opening, sintering aid, superior corrosion resistance, and cost-effectiveness.
