Applications of Refractory Bricks


In the glass industry, high-temperature refractory bricks are used for lining of glass kilns, bottoms of glass melting furnace, insulation layers, flues, and so on. Bricks can withstand high temperatures and maintain a stable structure. This can help improve the safety and durability of equipment.

Chemical Industry

In the chemical industry, refractory bricks also have a wide range of applications. They are mainly used in the construction of reactors, furnaces, and chemical equipment, such as fertilizer plants, sulfuric acid plants, phosphate plants, hydrogen plants, ethanol plants, calcination plants, ceramic plants, and so on. They can protect these equipment from the effects of high temperatures and chemical corrosion.

Environmental Protection Industry

The high temp refractory bricks can be used for the linings of the following furnaces in the energy, petroleum, and environmental protection industries, such as waste incinerators, waste-to-energy plant combustion furnaces, gasifiers, petroleum refining cracking furnaces, distillation towers, coke ovens, carbon roasters, circulating fluidized bed, and so on. Refractory bricks can help these equipment resist high temperatures and chemical corrosion.

Nonferrous Metals

In the non-ferrous metal industry, refractory blocks are used in the smelting of non-ferrous metals to make linings for furnaces and casting molds, such as smelting furnaces, heat treatment furnaces, electrolytic cells, and so on. Bricks are typically applied in industries involved in the smelting of copper, aluminum, nickel, zinc, lead, and tin.

Steel Smelting Industry

Refractory materials can be used for refractory brick lining and insulation layers in some furnaces, such as high-temperature kilns, steelmaking furnaces, ladles, tundishes, converters, electric furnaces, hot blast stoves, refining furnaces, and so on. These refractory materials can ensure that equipment operates normally in high-temperature chemical environments.

Cement & Lime

Refractory bricks can be used in cement kilns, lime kilns, and other applications. They can be used for the construction of linings, furnace walls, furnace roofs, furnace bottoms, flues, insulation layers, insulation layers, and so on. This can help equipment operate well in high temperature and corrosive conditions.
