48% High Alumina Brick | Refractory Brick for Industrial Furnace Lining

Product Description:
48% high alumina brick is a medium-duty refractory brick designed for industrial furnace applications. It provides stable thermal performance, good mechanical strength, and reliable resistance to moderate high temperatures. This product is widely used as lining material in various industrial kilns and furnaces where cost efficiency and durability are required.

Key Features:

Good Thermal Resistance：Suitable for continuous operation in medium-temperature industrial furnaces up to 1350°C.

Stable Mechanical Strength：High cold crushing strength ensures structural stability under load-bearing conditions.

Cost-Effective Solution：Optimized alumina content provides a balance between performance and material cost.

Reliable Furnace Performance：Reduces lining failure risk and improves overall furnace service life.

Application:
Industrial Furnace Lining：Used in general industrial furnaces where stable thermal resistance and structural strength are required for long-term operation.

Ceramic Kiln：Applied in firing zones and insulation layers of ceramic kilns to ensure stable heat performance and energy efficiency.

Cement Kiln (Low to Medium Temperature Zones)：Suitable for preheating and transition zones in cement rotary kilns with moderate thermal load and abrasion conditions.

Heat Treatment Furnaces：Used in heat treatment systems to provide reliable lining performance under continuous heating and cooling cycles.

Standard Sizes:
We supply international standard refractory brick sizes suitable for furnace construction and industrial applications.
