Product Introduction:
High alumina brick refers to refractory products with Al2O3 content higher than 48%.It is made of bauxite or other raw materials of high alumina content .The refractoriness of high alumina brick can be more than 1770 C .
According to the content of Al2O3, high alumina bricks are usually divided into three grades: Grade I Al2O3 content 75%; Grade II Al2O3 content is 60 75%; Grade III Al2O3 content is 48~60%.
Application:
High alumina bricks are mainly used for lining blast furnaces, hot blast furnace, electric furnace roofs, blast furnaces,reverberatory furnaces, and rotary kilns.
Features:
1.Low creep.
2.Good slag resistance.
3.Strong thermal shock stability.
4.Good erosion resistance.
