We are a refractory material manufacturer, with four major factories: heavy brick factory, light brick factory, monolithic refractory factory and fused-cast brick factory.
We promise to provide you with high-quality refractory materials.
Product description of high Alumina Brick
High alumina bricks are made of highly sintered selected bauxite at 1420-1530 ℃ through advanced technology and strict quality control. We can provide you with the ex factory prices of SK36, SK37, SK38 and SK40 refractory alumina bricks. The indicators of these products are shown in the following table.
Characters of high Alumina Brick
- High temperature resistance.
- Resistance to chemical attack.
- Thermal stability.
- Anti dross.
