Basic Refractory Bricks are a type of refractory material. They mainly consist of alkaline oxides like magnesia and calcium oxide. They have good resistance to high temperatures and basic slag corrosion. Widely used in steel – making furnaces, glass kilns, etc., they play a crucial role in high – temperature industrial applications. The following are several common KERUI Basic Refractory Bricks.
