Beschrijving

Silicon carbide pipes are also known as silicon ceramic pipes, which belong to the refractory pipe family.It is crystallized from silicon nitride and silicon carbide,which has good wear resistance, heat resistance, corrosion resistance and high temperature performance. Silicon carbide pipe is the ideal lining material of smelting steel industry, because it has the advantages of high temperature resistance, good slag erosion resistance, high strength and long service life.
 

Material	Component %	Temperature in common use °C	Characteristic
Recrystallized SiC	SiC 98	1400	Good gas tightness,heat-resisting,strong concussion,excellent wear-resistantance.in the atmosphere of oxidation and reducing property,can be used to 1600°C.

 

Application

 

Silicon carbide tubes are mainly used in medium frequency forging, various heat treatment electric furnaces, metallurgy, chemical industry, non-ferrous metal smelting and other industries. Widely used in metallurgical sintering furnace and intermediate frequency heating forging furnace. Length can be designed.



 

Feature

SiC thermal couple protection tube is oxidation resistance, high thermal conductivity, corrosion resistance, low coefficient of thermal expansion. They can be used in metallurgy industry, chemical industry and ceramics industry. They can be used as temperature-checking protection tubes.
