High alumina brick is kind of alumina silicate refractory material, made of superior bauxite and other additives at high temperature, with Al2O3 content above 48%. With unique advanced technology, the normally max service temperature is above 1420~1550°C. Xinmi City is China’ largest high alumina bricks manufacturing base.
Classification by Al2O3 content: SK38, SK37, SK36, SK35, the shapes include standard bricks, irregular bricks, specific bricks.
High alumina brick can be widely used in blast furnace, EAF, steel ladle, boiler, lime & cement kiln, glass kiln etc.
Specification should be different according to different furnaces/kilns, standard shapes and customized drawings are acceptable.
