1. In the metallurgical industry, the production of shaped refractory materials (various specifications of bricks) and amorphous refractory materials accounts for about 70% of all refractory materials. The hard clay in clay bricks is used to manufacture blast furnace refractory materials, ironmaking furnaces, hot blast furnaces, steel barrel lining bricks, plug bricks, and high alumina clay bricks are used to manufacture electric furnaces, blast furnace lining bricks, and high alumina refractory slurries, However, hard clay and high alumina refractory mud are usually used to calcine mature materials at high temperatures (1400-1800 ℃).
2. In the grinding industry, chemical industry, and ceramic industry, clay bricks also have important applications. High alumina clay is melted in an electric arc furnace to produce grinding materials. Among them, fused corundum abrasive is one of the widely used abrasives, accounting for two-thirds of all abrasive products. High alumina clay can be used to manufacture various aluminum compounds, such as aluminum sulfate, aluminum hydroxide, aluminum chloride, potassium aluminum sulfate, and other chemical products. In the ceramic industry, Hard clay and semi hard clay can be used as raw materials for manufacturing daily ceramics, architectural ceramics, and industrial ceramics.
In the building materials industry, high alumina bricks, phosphate high alumina refractory bricks, and high alumina fused cast high alumina clay are used to manufacture cement kilns and glass furnaces using clay bricks. After being calcined, they are mixed with limestone to produce aluminum cement, which has the characteristics of rapid setting, corrosion resistance, and thermal energy erosion resistance.
