Application

Alumina ceramic furnace tubes are widely used in high temperature tube furnaces, the operating temperature can reach 1600 ºC, and the conventional diameter is 60mm-120mm. The corundum furnace tube is an important ceramic part of the tube furnace. It is installed in the middle of the furnace. Both ends are covered with metal flanges for sealing. The material is put into the crucible and placed in the furnace tube.

Advantage

-The porosity is 0,Good tightness,air tight

-High temperature resistance,1600ºC

-Stand wear and tear

-High hardness 

-High strength

-Resistance to electric breakdown
