High alumina arc brick is a kind of special refractory brick, mainly designed for steel ladle linings in metallurgy industry. Today arc brick is made of bauxite as the raw material, high alumina content with 48%~75%, and being calcined at high temperature in tunnel kiln. It has replaced the past years’ chamotte or clay material, and highly improved refractoriness up to 1790℃, and refractoriness under load up to 1500℃, and with superior resistance to slag.
STOCK SIZE: 280*100*100mm 220*100*100mm
Classification by alumina content: LZ-55, LZ-65, LZ-75
Mainly applied in steel ladle linings, hot blast furnace, electric furnace, boilers, cement rotary kiln and casting steel bricks, etc.
