High Alumina Refractory Brick: Premium Solution for Industrial High-Temperature Furnaces

1. What Are High Alumina Refractory Bricks?
High alumina refractory bricks are premium high-temperature refractory materials crafted from high-purity calcined bauxite. Featuring Al₂O₃ content from 60% to 85%, these high alumina fire bricks outperform ordinary clay bricks in thermal stability and durability. Adopting a 100% pure no-mixing formula, our bricks maintain stable chemical properties and low porosity, perfectly suited for heavy-duty industrial furnace lining and thermal insulation projects across various industries.

2. Core Performance Advantages
High alumina refractory bricks stand out for their excellent comprehensive performance. With a refractoriness of over 1770°C, high compressive strength and load softening resistance, they resist deformation in long-term high-temperature working environments. They also deliver strong tolerance against thermal shock, slag corrosion and molten metal erosion. Their low creep characteristic effectively stabilizes furnace structures, lowers maintenance costs, and greatly prolongs the service life of industrial kilns and furnaces.

3. Common Industrial Applications
Versatile and practical, high alumina bricks are widely applied in high-temperature industrial facilities. Typical scenarios include cement rotary kilns, industrial boilers, steel smelting furnaces, non-ferrous metal furnaces, glass kilns and thermal power equipment. We provide multiple mainstream grades including 70%, 75%, and 80-85% Al₂O₃ high alumina bricks to match different working temperatures and project requirements.
