High refractoriness 230*114*65mm High Alumina Fire Proof brick for Industrial furnace 65% Al2O3
High alumina brick is a neutral refractory with alumina content not less than 48%. The product takes high grade bauxite as raw materials, molding by high pressure. General high-alumina brick SK34, SK36, SK37, SK38, SK40 produced by us with high quality, mainly used in steel industry, non-ferrou metal industry, metallurgical industry, power industry and other industies. Such as blast furnace, hot blast stove, rotary kiln lining, electric furnace top and have exported to all over the world.
High alumina brick produced by our factory with features of:
1, High temp performance, thermal stability
2, Good slag resistance, high alumina brick is neutral refractory material, can resist the acid slag and alkaline slag erosion.
3, High refractoriness, compared with clay and semi-silica brick, high alumina brick refractoriness can be 1750 ℃-1790 ℃.
