Metallurgical protection slag, covering agent
It is mainly used as the base material for the production of pellet slab continuous casting, die casting protection slag and carbon-free protection slag. Because the composition of wollastonite is stable, the casting blank has no defect and the surface is smooth. Because the CaO and SiO2 in wollastonite exist in the combined state, the ratio is just in the alkalinity range required by continuous casting, which can reduce the types of base material, simplify the process, and make the protective slag have good thermal stability. Because the wollastonite contains very low Al2O3, it can enhance the performance of the protection slag to absorb Al2O3.
Slag adjusting agent for steelmaking, low aluminum prefusion slag
Due to the stable chemical properties of wollastonite and the appropriate alkalinity, small pieces of wollastonite can be used as slag adjusting agent, low aluminum pre-fusion slag directly used for deoxidation of molten steel, increase the fluidity of molten steel, remove non-metallic inclusions in molten steel, and is an ideal metallurgical auxiliary material for smelting special steel and pure steel
Welding materials and flux
Wollastonite is used for welding rod coating to accelerate the melting speed and improve the fluidity of molten slag. It has been applied abroad for many years. Wollastonite is used for welding rod coating, which has the advantages of energy saving, anti-porosity, enhancing weld strength, making weld surface smooth, improving melt drop transition, accelerating coating melting rate and so on. In particular, our company wollastonite contains low impurity, good quality, suitable for special welding rod, buried flux
