Product Description

High Alumina Bricks manufacturing process is similar to much grog clay brick, the different is there are higher proportion of grog in ingredients that can reach 90~95%. Select and screening deironing before the grog crushed. Firing temperature is higher, as of Grade I &II high alumina bricks fired in the tunnel kiln is 1500~1600 ℃.Chinese production practice shows that select, grading and keep in storage high alumina grog before crushed. Adopt fine grinding methods calcined bauxite and mixed clay to improve products’ quality.

According to the different resource situation and production requirement, adopt below several raw materials: high-alumina bauxite, sillimanite mineral and synthetic raw materials. There are abundant resources of high-alumina bauxite with fine quality in China.RS Company purchases raw materials only from our trusted suppliers that we have cooperated with for long term. All the raw materials shall be checked strictly upon they reached the factory. Each production process will be controlled strictly to ensure the quality and consistency so that providing customers with the best quality high alumina bricks.

Features
1.Excellent strength at ambient and elevated temperatures.
2.High compressive strength.
3.Very low levels of iron and other impurities.
