The refractory temperature range of refractory bricks is usually between 1000 ℃ and 2000 ℃, depending on their material and manufacturing process. For example, the refractory temperature of ordinary refractory bricks is generally between 1580 ℃ and 1770 ℃, while refractory bricks made of special materials such as corundum, mullite, and silicon carbide can even reach a refractory temperature of over 2000 ℃. In addition, the use temperature of refractory bricks containing carbon and zirconium is above 1900 ℃, the use temperature of silicon aluminum refractory bricks is between 1500 ℃ and 1750 ℃, and the use temperature of thermal insulation refractory bricks is usually between 1200 ℃ and 1500 ℃.
