The refractory bricks for the furnace wall should consider factors such as the temperature inside the furnace, chemical environment, pressure, etc. Usually, it is necessary to select suitable refractory brick products based on specific working conditions and material properties, which are suitable for different furnace wall working environments.
Clay bricks: commonly used in general furnace wall applications, with relatively low prices, but limited durability in high temperature and chemically corrosive environments.
Phosphate refractory bricks: used in phosphate smelting furnaces and other equipment with acidic environments, with good corrosion resistance.
Mullite refractory brick: It has good thermal stability and mechanical strength at high temperatures and is suitable for high-temperature industrial furnaces.
Corundum brick: made of alumina, it has good corrosion resistance and fire resistance at high temperatures, and is suitable for iron smelting furnaces, steel industry furnaces, etc.
Chromium corundum brick: containing chromium oxide, used in environments that are resistant to high temperature and strong acid alkali corrosion, such as glass kilns and metallurgical furnaces.
Silicon carbide refractory bricks: suitable for high temperature environments, such as electric arc furnaces, silicon alloy furnaces, etc., with good thermal shock resistance.
Nitride silicon bricks: used in high temperature and highly corrosive environments, such as high-temperature molten metal processing furnaces.
