High Thermal Resistance High Alumina Fire Bricks is widely used in lots of industry, such as metallurgical industry, like hot blast stove and blast furnace for Iron-making, lime kiln for production of lime, and rotary kiln and reheating stoves etc.
High Thermal Resistance High Alumina Fire Bricks can work even on1500 ℃ high temperature as well as keep good state, it also can resist compressive strength of more than 80Mpa, along iwth more than 30 times shock resistance (water cooling).

High Thermal Resistance High Alumina Fire Bricks are produced with selected bauxite chamotte by advanced process and strict quality control. The main mineral components are corundum and mullite phases. Its features are excellent high temperature mechanics and chemical corrosion resistance.
It is called corundum brick,if Al2O3 content is higher than 90%, . Due to different resources, national standards are not completely consistent. In China, according to the content of Al2O3 in High Thermal Resistance High Alumina Fire Bricks , it is usually divided into three grades: Grade I──Al2O3 content>75%; Grade II──Al2O3 content is 60～75%; Grade III──Al2O3 content is 48～60%.
The production process of High Thermal Resistance High Alumina Fire Bricks and multi-clinker clay bricks also the same.
The difference is that the proportion of clinker in the ingredients is higher, which can be as high as 90-95%.
The clinker needs to be sorted and sieved to remove iron before crushing, and the firing temperature Higher, such as Ⅰ, Ⅱ high alumina bricks are generally 1500～1600℃ when fired in tunnel kiln.
