First of all, refractory material is a kind of inorganic nonmetallic material with the refractoriness no less than 1580℃. Refractory generally refers to the refractory cone sample in the case of no load, resistance to high temperature without softening the melting Celsius temperature. As a necessity of industrial basic materials. Refractory has been widely used in steel, metallurgy, chemical industry, petroleum, machinery manufacturing, electricity, power and other industrial fields.
The current refractory technology is in accordance with the development needs of modern industry and industrial intelligent manufacturing, through physical research, chemical analysis, material design, material processing, test and a series of research process, to create a new refractory technology to meet the needs of various industries.
The production process of refractory materials is different according to the density and shape of the products, including sintering method, melting casting method and melting spray blowing method. However, with the continuous innovation and implementation of new refractory production, there will be more and more suitable for the new refractory production process in the production process. But pay more attention to energy saving, low carbon and environmental protection.
Refractory products mainly refer to refractory materials with high strength, high hardness, high temperature resistance, wear resistance, corrosion resistance and other performance requirements. It is used in steel, nonferrous metal, glass, cement, ceramics, petrochemical, machinery, boiler, light industry, electric power and other fields, and also plays an irreplaceable important role in the development of high-temperature industrial production.
At present, with the continuous development of high and new technology as the basis of high and new technology and the forerunner of refractory material and application range is gradually becomes more extensive, besides should outside the industry, refractory materials has been gradually extended to the electronic information, new energy, ecological environment, biological medicine, waste treatment, new buildings and military industry and other major fields.
