Wollastonite has stable chemical properties and its alkalinity is close to 1. It is the ideal raw material for continuous casting powder, making continuous casting powder has good thermal stability and meeting the thermal insulation, lubricating casting billet and other effects. And at the same time it can reduce the raw material types of continuous casting powder, simplifying the production process, reducing the production cost. It has been widely used in die casting, continuous casting (slab, billet), synthetic slag and stainless steel continuous casting, etc. The Wollastonite product of Xinyu South has the advantage of low content of Al, S, P, low melting point and viscosity, which can enhance the performance of the protective slag to absorb Al2O3 and other inclusions.
