1. Metallurgical
It has stable chemical property and low loss on ignition after physics & chemistry composited, also its component ratio is within the basicity range which metallurgical fluxes needed. It can reduce slag type, simplify production process, make the metallurgical fluxes have good thermal stability, cause the effect of thermal insulation, isolate air, lubricate ingot blank and impove the heat transfer property. Our wollastonite have low contents of Al2O3\S\P, low melting point and low viscosity, so it can enhance the property of absorbing Al2O3 and other impurities. Also, According to the special requirements of customers, we can produce slag-adjustment materials in different alkalinity. 2.
