Product Description

What's High Alumina Bricks?

High aluminum refractory brick is a common refractory material, usually made of high bauxite as the main raw material, through high temperature calcination. It has excellent fire resistance and high temperature resistance, and is often used in a variety of industrial furnaces, melting furnaces, glass kilns and other high-temperature equipment lining and masonry. High aluminum refractory bricks usually have a high refractoriness and can withstand high temperatures of more than 1700 ºC Celsius, so they are widely used in industrial production.

 

KERUI high aluminum bricks have excellent high temperature resistance, can be used at 1400 to 1700ºC, and have good chemical stability,Low apparent porosity of 19%-21%, alumina content between 55%-80%, can be used for a long time.
