Refractory Materials, Production

Depending on the product density and shape different sintering, casting method and melting injection method. Sintering firing clinker is part of raw materials, crushing and screening, according to a certain proportion of mixed with raw materials, through shaping, drying and firing. Raw materials burn-which is the purpose of water and organic impurities, decomposition of sulfate gas burning to reduce the shrinkage of fired products, ensure product accuracy of dimensions. After the crushing and grinding of raw materials also have to go through screening, because blank graded by a different particle size powders, can ensure the close packing of dense body.
