High Alumina Anchor Brick Description
High Alumina Anchor Brick is a type of refractory brick made from high alumina materials. It is designed specifically to anchor or secure refractory linings in high-temperature furnaces, kilns, and other heat-intensive equipment. These bricks are known for their high alumina content, which typically ranges from 50% to 90%, giving them excellent resistance to high temperatures, mechanical wear, and chemical corrosion.
