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

Product Description

Fused-cast corundum brick is produced using fused corundum as the primary raw material and manufactured through high-temperature melting and casting processes.

Features

• Extremely high density and very low porosity

• Excellent high-temperature strength and creep resistance

• Outstanding resistance to corrosion, erosion, and abrasion

• Excellent chemical stability against molten slag and glass

• Moderate thermal shock resistance, slightly lower than that of sintered corundum bricks

• Excellent volume stability at high temperatures with low spalling tendency

Typical Applications

• Glass Industry: Glass melting furnaces, float glass furnaces, tank throats, breast walls, end walls, and forehearths

• Metallurgical Industry: Ladles, refining furnaces, slide gate plates, and high-temperature furnace linings

• Petrochemical Industry: High-temperature cracking furnaces and gasifier linings

• Other Applications: Various high-temperature furnaces requiring excellent corrosion and erosion resistance
