It can reduce slag type, simplify production process, make the metallurgical fluxes have good thermal stability, to 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.<BR>In the electrode coating, wollastonite can accelerate the melting rate with the advantage of energy-saving, porosity, increase seam strength, promote smooth surface, improve droplet excessive, accelerating the melting speed of coating. Our wollastonite have low content of impurities, so it is suitable for special electrode and flux.<BR> <BR>2009-7-6 10:14:14
