Refractory Brick
High-alumina bricks are aluminium-silicon refractory products made of bauxite clinker with a certain amount of combined clay with an Al2O3 content greater than 48%. The Chinese standard (GB/T2988-1987) divides high-alumina bricks into four grades according to physical and chemical indicators: LZ75, LZ-65, LZ-55 and LZ-48.

Clay brick is a refractory product with AL2O3 content of 30%~48% produced from refractory clay. Clay bricks are widely used in many thermal equipment such as blast furnaces, hot blast furnaces, steel drum linings and steel pouring systems. Its production accounts for more than half of the total production of refractory materials. Clay bricks are divided into varieties such as ordinary clay bricks, multi-clinker clay bricks, whole raw clay bricks, and high-siliceous clay bricks.
