General High Alumina rafactory brick SK36 SK37 SK38 230*114*65mm Industrial furnace
refractory material
General High alumina brick is a commonly used refractory with alumina content not less than 48%. Our factory produces general high-alumina brick SK34, SK36, SK37, SK38, SK40 takes high grade bauxite as raw materials, molding by high pressure and firing at high temperature.
High alumina brick three significant features are:
1, High refractoriness, compared with clay and semi-silica brick, high alumina brick refractoriness can be 1750 ℃-1790 ℃.
2, High temp performance, thermal stability and little permanent linear change.
3, Good slag resistance, high alumina brick is neutral refractory material, can resist the acid slag and alkaline slag erosion.
High alumina brick is widely used:
1, Steel industry: Blast furnace, Hot blast stove
2, Power industry: Electric furnace top
3, Metallurgical industry: Rotary kiln lining
4, Non-ferrous metal industry
