Product Overview
Leadsun high alumina bricks are made from high-quality bauxite chamotte under advanced production techniques and strict quality inspection. With corundum and mullite as the main mineral phases, the bricks offer outstanding high-temperature strength, excellent chemical corrosion resistance, and long service life.
Key Advantages
- Excellent high-temperature resistance for continuous industrial use
- High alumina content ensures superior refractoriness and thermal stability
- High bulk density and low porosity for enhanced strength and durability
- Outstanding resistance to slag, erosion, and chemical corrosion
- Stable performance under severe thermal shock conditions
- Long service life, reducing furnace downtime and maintenance costs
- Suitable for steel, cement, glass, and metallurgical furnaces
- Cost-effective refractory solution with consistent quality
