China Chinese wholesale Types Of Refractory Bricks - High Quality 70% Fire High Alumina Brick For Hot-Blast Stove Gas Burner – Rongsheng factory and manufacturers | Rongsheng Detail:

High alumina brick is produced with select bauxite chamotte as main raw material, fired at 1450-1470°C by advanced process with strict quality control. High Alumina Fire Bricks are manufactured with alumina or other raw materials containing higher alumina content through molding and firing. because of its neutral refractory property alumina refractory can resist acid slag erosion resistance.

High Alumina Brick Process

Get through Select and sieve chamotte for deironing before breaking, which can improve high alumina bricks quality. Because there are higher proportion of grog in ingredients that can reach 90~95%. Select and screening deironing before the grog crushed.

Three Grades of High Alumina Brick

According to different Al2O3 content, High alumina bricks can be classified into Three Grades in China.

Grade I High Alumina Bricks have more than 75% Al2O3 content.

Grade II High Alumina Bricks have 60~75% Al2O3 content.

Grade III High Alumina Bricks have 48~60% Al2O3 content.

Features of High Alumina Brick

High alumina brick has great features like high temperature performance, great corrosion and wear resistance, high bulk density, low iron content, etc.
