Corundum-Mullite refractory refractory brick High-Alumina Brick High temperature high refractoriness refractory materials

Product Description

Corundum mullite brick is a high-performance refractory material mainly produced from fused corundum and mullite. It combines the excellent high-temperature strength of corundum with the good thermal shock resistance of mullite, making it suitable for demanding high-temperature environments.

Feature

High Al₂O₃ content with excellent high-temperature strength.
Good thermal shock resistance and minimal permanent linear change at high temperatures.
Excellent resistance to slag corrosion and erosion.
High density and low porosity, providing good volume stability.
Suitable for severe high-temperature environments with strong corrosion and erosion.

Typical Application

Metallurgical Industry: Ladles, refining furnaces, heating furnaces, heat-treatment furnaces, and high-temperature sections of hot-blast stoves.
Glass Industry: Regenerators of glass furnaces, furnace bottoms, and high-temperature furnace linings.
Ceramic and Building Materials Industry: Linings for tunnel kilns, roller kilns, and shuttle kilns.
Petrochemical Industry: Linings for high-temperature cracking furnaces and gasifiers.
Other Industrial Furnaces: Components exposed to severe erosion, corrosion, and high-temperature loads.
