Silicon nitride heater protection tube

Heater protection tube apply in aluminum holding furnace or melting furnace casting industry furnace.

Material: Silicon nitride

Because of its excellent high temperature performance, silicon nitride ceramic has become the first choice material of the electric or gas heater’s protective tube.

Due to its excellent high temperature resistance and strong thermal shock resistance, silicon nitride ceramic product can withstand the heat load of a high temperature heating element or burner for a long time, and the service life is up to more than one year;

Silicon nitride ceramics hardly react with the aluminum liquid, so it will not pollute the aluminum liquid, which is conducive to improve the purity of aluminum liquid under high temperature;

Compared with the traditional upper radiant heating method, its energy efficiency can achieve 20%-30%, and it effectively avoids the aluminum liquid at the upper side to be excessive oxidation.

Zhejiang Shangguijuli Special Material Technology Co., Ltd. is a leading manufacturer specializing in R&D and production of high-performance silicon nitride ceramic material in China. With the advanced production process of silicon nitride ceramic and precision machining technology, we provide professional and most suitable solution of silicon nitride material for customers in the field of advanced equipment,new energy, electric vehicles, aerospace etc.
