Corundum protection tube

Corundum tube are suitable for all kinds of metal, non-metallic sample analysis and the molten material. Corundum tube is mainly used in high temperature vacuum tube furnace, vacuum furnace atmosphere, float glass industry in tin bath tube, solar glass in protecting tube, electric stove wire supporting tube, aluminium trichloride industry chlorine pipe, muffle furnace furnace tube, etc. , products using temperature is 1200 - 1800 degrees, the product density, good thermal shock resistance, acid and alkali resistance, scouring resistance, long life and other characteristics favored by the majority high-tech colleges and electric industry and the use of units of praise. Vacuum furnace tube in 1800 according to the customer feedback within 100 times service life, the service life of the tin bath tube used for up to six years.

:

1, high purity: Al2O3 & gt; 99%, good resistance to chemical corrosion

2, good temperature resistance, use for a long time at 1600 ℃ and 1800 ℃ short term
