Shaped refractory materials, as the traditional core category of refractory materials, can be divided into various types such as fire clay bricks, high-alumina bricks, and magnesia bricks according to their compositions, which are suitable for different working conditions. Fire clay bricks have wide raw material resources and good thermal stability, and are often used in furnace flues and linings with temperatures below 1250℃; high-alumina bricks have excellent high-temperature strength and can be applied to high-temperature zones of furnaces and masonries with large loads, with a service temperature of 1300-1650℃. Shaped refractory materials, with the characteristics of stable structure and convenient construction, still occupy an important position in large thermal equipment such as coke ovens, glass kilns, and blast furnaces, and are the basic protective materials for high-temperature industries.
