The basic requirements of mold casting for protective slag are low density, low melting point, alkalinity (CaO/SiO2) ratio less than 1, appropriate melting speed and better spreadability. Wollastonite has the characteristics of low temperature melting, stable chemical composition, high purity, alkalinity (CaO/SiO2) tends to be neutral. This excellent characteristic provides an ideal raw material for the protective casting material of metallurgical steelmaking, especially the wollastonite contains very little Al2O3, so the metallurgical protective slag made has a strong ability to adsorb the harmful inclusion Al2O3 in the molten steel, so it is widely used in the metallurgical industry. Metallurgical auxiliary raw materials require wollastonite ≥50%, calcite ≤50%, quartz ≤5%, S≤0.01%, P≤0.01%. 12% to 15% of the world's wollastonite is consumed in this field every year. Now from common carbon steel, manganese steel to stainless steel continuous casting, slag type from small billet, large square billet, slab to furnace refining, etc., are widely used to wollite as the base material protection slag, quickly replaced the expensive imported protection slag, has played a role in promoting the development of metallurgical steelmaking industry.
