Depending on the degree of compactness and shape of the product, there are sintering methods, melt casting methods, and melt blowing methods. The sintering method is to pre-fire the raw materials of the department, crush and sift, and then mix with the raw materials according to a certain ratio, through molding, drying and firing. The smelting method is a process in which a raw material is mixed and finely ground through a batch, and is melted at a high temperature, directly cast, cooled and crystallized, and annealed to form a product. Their bodies are dense, with high mechanical strength, high structural strength, good slag resistance, and the use range is constantly expanding. The melt blowing method is a method in which the ingredients are melted and then sprayed with high-pressure air or superheated steam to disperse them into fibers or hollow spheres. The product is mainly used as a light refractory and heat-insulating material, and can also be made into a powdery or granular unshaped refractory material. When it is used, it is cemented with a binder such as tar, asphalt, cement, phosphate, sulfate or chloride. It is directly used for molding and sintering.
