3rd Grade 55%Al2O3 High Alumina Refractory Bricks Standard SK36 Slag Resistant

3rd grade 55%Al2O3 High Alumina Fire brick Standard SK36 refractory material commonly used

3rd High alumina brick is a commonly used refractory with alumina content not less than 55%. The product takes high grade bauxite as raw materials, molding by high pressure and firing at high temperature. Our factory produces general high-alumina brick SK34, SK36, SK37, SK38, SK40 with high quality, the main features have:

1, High temp performance, thermal stability and little permanent linear change.

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 ℃.

High alumina brick application:

1, Non-ferrous metal industry 

2, Steel industry 

3, Metallurgical industry

4, Power industry

5, Such as blast furnace

6, Hot blast stove,

7, Rotary kiln lining,
