A. Alumina ceramic tubes are mainly used for protection tubes and insulating tubes of thermocouple thermometers of temperature measuring instruments.
B. It can also be used in furnace tubes of industrial resistance furnaces, experimental electric furnaces, and heat treatment furnaces.
C.99.5%-99.7% alumina ceramic tube is the main product of our factory. Conventional alumina ceramic tubes are available from stock all year round.
Alumina Furnace Pipe
My factory looking for distributors.
Alumina ceramic belongs to the addition of special ceramics, our factory mainly produces aluminum oxide content is between 99.3% and 99.7% of high purity alumina alumina ceramic piece, its main composition is AL2O3 as raw material, finished product after sintering hardness can reach mohs hardness grade 9, because it's super abrasion resistance, impact resistance and strong corrosion resistance, high hardness, mechanical performance is remarkable.
Has been widely used in cement, steel, thermal power, coal, smelting, chemical, port, mining and other industries in the easy to wear equipment, become to extend the life of mechanical equipment, protect equipment is not easy to be damaged, reduce the enterprise operating costs of the umbrella.
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.
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.
