Flint Clay High Alumina Refractory Bricks For Rotary Kiln
High Refractoriness Under Load Alumina Silicat Standard Brick is widely used in metallurgical industry, like hot blast stove and blast furnace for Iron-making, lime kiln for production of lime, and rotary kiln and reheating stoves.
High Refractoriness Under Load Alumina Silicat Standard Brick can resist 1500 ℃ high temperature as well as keep good state, it also can resist compressive strength of at least 80Mpa, along iwth more than 30 times shock resistance (water cooling).

High Refractoriness Under Load Alumina Silicat Standard Brick 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.
If Al2O3 content is higher than 90%, it is called corundum brick. Due to different resources, national standards are not completely consistent. For example, European countries have stipulated that the lower limit of Al2O3 content for high-alumina refractories is 42%. In China, according to the content of Al2O3 in High Refractoriness Under Load Alumina Silicat Standard Brick, 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 Refractoriness Under Load Alumina Silicat Standard Brick and multi-clinker clay bricks are similar.
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.
Production practice in China has proved that before crushing, high-aluminum clinker is strictly sorted and classified, and stored in tiers.
The use of bauxite clinker and combined clay fine grinding method can improve product quality.
