Application

High aluminum insulation bricks are mainly used as insulation materials in various industrial kilns that do not contact molten materials and have no corrosive gas effects. The use temperature is 1200-1400℃. Mainly used in thermal boilers, glass kilns, cement kilns, fertilizer gasification furnaces, blast furnaces, hot air furnaces, coking furnaces, electric furnaces, casting and steel pouring bricks, etc.

High aluminum insulation bricks can also be used as hot surface refractory materials or other refractory materials to support insulation layers, used in melting furnaces, ignition kilns, flues, refining devices, heating devices, regeneration devices, gas furnaces and pipelines, soaking furnaces, annealing furnaces, reaction chambers and other industrial thermal equipment.
