Standard high grade 80% Al2O3 White High Alumina Fire brick for Industrial furnace Slag resistant
Superior high grade High alumina brick is a neutral refractory with alumina content more than 80%. The product takes superior bauxite as raw materials formed by molding and calcination.
High alumina brick produced by our factory with features of:
1, Good slag resistance, high alumina brick is neutral refractory material, can resist the acid slag and alkaline slag erosion.
2, High temp performance, thermal stability
3, High refractoriness, compared with clay and semi-silica brick, high alumina brick refractoriness can be 1750 ℃-1790 ℃.
Our main products are general high-alumina brick SK34, SK36, SK37, SK38, SK40 that with high quality, mainly used for blast furnace, hot blast stove, rotary kiln lining, electric furnace top and have exported to all over the world.
