Light burned magnesium ball It is the basic material in the field of high-temperature technology. The application department is very extensive. Among them, the most common application is as structural materials and linings resistant to high temperature in various thermal equipment and high temperature vessels. In iron and steel metallurgy industry, coke ovens are mainly made of refractory materials. The blast furnace and hot blast furnace for iron making, various steelmaking furnaces, soaking pits, heating furnaces, etc. must have various refractory materials that meet the requirements. Not only die casting of molten steel consumes a lot of refractory materials, but also continuous casting needs some high-quality refractory materials. There is no way to realize secondary refining without high-quality refractory materials. The statistical results show that the steel industry needs the most refractory materials, accounting for about the total output of refractory materials. Refractory materials are also indispensable for pyrometallurgy and thermal processing of non-ferrous metals. All high temperature furnaces or their linings in building materials industry and other high temperature operation departments producing silicate products, such as glass industry, cement industry and ceramic industry, must be constructed with refractory materials. Refractory materials are required for all kinds of baking furnaces, sintering furnaces, heating furnaces, boilers and their attached flue, chimney, protective layer, etc. in industrial high-temperature operation departments such as chemical industry, power, machinery manufacturing, etc.
In a word, when a certain structure, device, equipment or container is used and operated at a high temperature of about above, the deformation, softening, melting, erosion, erosion, collapse and damage of materials may occur due to physical, chemical, mechanical and other effects, which may not only make the operation impossible, interrupt the service life of materials, and affect production, Moreover, the processing object is polluted and the product quality is affected, so this refractory material with high temperature resistance must be used
