Properties of alumina corundum tube


Alumina corundum tube has high density, which greatly reduces secondary oxidation of molten steel during pouring and reduces inclusion entering the casting model.

High fire resistance (> 1680*C), erosion resistance, smooth surface of runner after pouring, and no corrosion during pouring. Good chemical stability, no chemical reaction with molten metal (molten iron or molten steel) of castings at high temperature.

High thermal strength and good thermoplasticity can effectively prevent sand washing and sand inclusion and reduce sand hole defects of castings. 

The coefficient of thermal expansion is low and has little influence on the shrinkage of the casting. The tensile cracking phenomenon caused by the pouring system is reduced. 

The surface is fine and smooth, the runner resistance is small and the flow velocity is fast. The invention can effectively reduce the thermal cracking caused by thermal stress generated in the casting due to various resistances of the casting by the gating system, the casting mold, the sand core and the casting structure. 


Industrial Ceramic Tube


We only make high purity alumina ceramics


1. High-purity alumina content 99.3% -99.5%, other alumina ceramics 92% -99%.
2. The color of high purity alumina product is milky white, and other products are pink or white. The higher the purity, the more transparent the color.
3. Alumina is a refractory material, the higher the purity, the better the refractory effect
4. After high-purity alumina ceramics are fired and cooled in a 1800-degree high-temperature kiln, the products are not easy to break when they encounter high temperatures. Other ceramics are fired at 1500 ℃ ~ 1800 ℃.
5. The volume density of high-purity alumina> 3.92 g / cm3 has a smooth surface and is not easily corroded by chemicals. The bulk density of other ceramics is> 3.70 g / cm3 ~> 3.85 g / cm3.

6. High purity alumina has good hardness and good wear resistance.
7. High purity alumina products have a longer service life.
