Raw Materials of High Alumina Dense Brick Resist 1300℃
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.
One of the important working properties of High Alumina Dense Brick is the structural strength at high temperatures. The high-temperature creep properties are also measured to reflect the high-temperature structural strength. From the test, we knew that, with the increase of the Al2O3 content, the structural strength also become higher.
When the content of Al2O3 less than 70%, the load softening temperature depends on the quantity ratio between the mullite crystal phase and liquid phase. With the increase in the quantity of mullite, It also increased. Therefore, reducing the content of impurities in the raw materials is beneficial to improve the quality of the High alumina refractory bricks.
Feature
1. Good Cold Crushing Strength
2. High Refractoriness Under Load
3. Good Thermal Shock Resistance
4. Low Reheating Linear Rate
Applications:
Generally suitable for thermal surface refractory lining or other refractory back lining insulation layer.
Refractory lining or thermal insulation for industrial furnaces in petroleum or chemical industries, such as ethylene cracking furnaces, tubular furnaces, reforming furnaces for synthetic ammonia, gas generators and high temperature shuttle kilns.
Tunnel kiln, push board kiln, roller kiln, wood kiln refractory lining material for industrial and household ceramics.
