Customized Fused Corundum Brick Kiln Fire Brick Wear-resistant Corundum Refractory Bricks For Industrial Furnace
Fused corundum bricks are highly sought-after due to their exceptional properties and are primarily composed of corundum as the main crystalline phase. The Alumina content of Fused Corundum Brick is greater than 90%, are the hot selling product of Rongsheng Group.
Applicaiton of Fused Corundum Brick
Fused corundum bricks are used in industries where extreme temperatures and corrosive environments are prevalent. Key applications include lining steelmaking furnaces, glass melting furnaces, ceramics kilns, chemical reactors, cement rotary kilns, non-ferrous metal furnaces, and power generation systems, among others. Their high compressive strength, resistance to acidic or alkaline substances, and ability to withstand temperatures over 1700°C make them indispensable in high-temperature industrial processes.
