Description

Technical Field

[0002] Refractory materials generally refer to a class of inorganic non-metallic materials with a refractoriness of not less than 1580 degrees Celsius. Refractoriness refers to the Celsius temperature at which a conical specimen of a refractory material can resist high temperature without softening and melting under no load. However, defining it only by its refractoriness can no longer fully describe refractory materials. 1580 degrees Celsius is not absolute. It is now defined as any material whose physical and chemical properties allow it to be used in a high temperature environment is called a refractory material. Refractory materials are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicates, power and other industrial fields, and are used in the metallurgical industry in the largest amount. At present, in the process of refractory product production, dust mixed in refractory materials greatly affects the production quality of refractory products, so dust removal must be carried out before this. The existing dust removal device only removes larger impurities in the refractory materials, and lighter impurities such as floating ash still remain in the refractory materials, which will also affect the production of refractory products.
