CCEFIRE ® DEHA Series High Alumina Refractory Brick

Product description

High alumina refractory brick is a kind of neutral refractory material with aluminum content more than 48%. High alumina refractory brick is made through calcination and molding from bauxite and other raw materials with high content of alumina. According to different content of alumina in high alumina brick, its fire resistance, refractoriness under load, compressive strength and other indicators are varied.
