High Alumina Brick Suppliers

High alumina brick CHINA Suppliers

High alumina brick using raw bauxite or other high alumina content,
Refractory bricks Abrasives by press forming different shapes, and finally calcined finished products

Refractory temperature

Refractoriness alumina bricks are higher than Fireclay Bricks, Silica Brick refractoriness, reaching 1750 ℃ ~ 1790 ℃, is an advanced refractories.

Load softening temperature

• Because high aluminum products high Al2O3, less impurities, forming little fusible vitreous, so load softening temperature higher than the Fireclay Bricks
• Because mullite crystallization did not form a network organization, so the load is still no brick high softening temperature.

Slag resistance

• Alumina bricks of Al2O3 more,Close to neutral refractories, can resist the erosion of acid and alkaline slag slag
• Because it contains SiO2, so the anti-alkaline weaker than the acid resistance capabilities
