99.5% alumina ceramic pipe is the main product of the factory. Conventional alumina ceramic pipes are available from stock all year round; Special alumina tube and groove tube are accepted.


Alumina Furnace Pipe

The alumina ceramic tube has high purity; the color is milky white; the outside is smooth and translucent.
The production and supply of alumina ceramic pipes are divided into extrusion molding and grouting molding.

Our alumina ceramic tubes are exported to more than 30 countries. The quality of our products is deeply liked by customers. Crucible products are also purchased by many university laboratories and mining laboratories. Parts products are also ordered by many large machine companies.


Alumina Furnace 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.

Instructions for use

When using alumina furnace tubes, it is best to control the heating and cooling rate to 5 degrees / minute, the slower the better.
Rapid cooling and rapid heating are one of the main reasons for the rupture of the alumina furnace tube. Our products have good resistance to quenching and heating.

Please keep the alumina furnace tube clean at all times, do not leave some samples in the alumina furnace tube, one side chemical reaction and cracking of the alumina furnace tube. It is recommended to   put the test sample into the crucible and alumina furnace tube.
During lofting and sampling, it is best to be within 200 degrees and slowly push from the edge to the middle. High temperature sample delivery and sampling is also the main reason for corundum tube  rupture.
Make sure to place mullite plugs on both sides of the alumina furnace tube to prevent heat radiation from damaging the silicone ring in the flange. The crucible should be placed in the middle of the alumina furnace tube.


Our factory

Jinzhou Yunxing Industrial Ceramics Co., Ltd. was established in 2000, mainly producing various types of tubular ceramic products and various industrial parts with alumina content above 99.3%. The factory covers an area of 4000 square meters.
