High Temperature Refractory Fire Brick is a specialized refractory brick made from high alumina materials. Designed for extreme environments, these bricks are ideal for use in high-temperature furnaces, kilns, and other heat-intensive equipment. With alumina content ranging from 50% to 90%, they offer superior resistance to high temperatures, mechanical wear, and chemical corrosion, making them essential for securing and anchoring refractory linings.
