Refractory bricks are materials designed to withstand high temperatures, chemical corrosion, and thermal shock. They are widely used in high-temperature industries such as metallurgy, chemical engineering, construction, and ceramics. Made from raw materials like bauxite, silica, and magnesite, refractory bricks offer excellent compressive strength, heat resistance, and thermal stability. They effectively insulate heat, improve energy efficiency, and extend the service life of equipment. Depending on the application, there are various types of refractory bricks, including high alumina, silica, and magnesite bricks, which are essential for furnaces, boilers, and other high-temperature devices.
