Refractory kiln furniture SiSiC Silicon carbide tube for sanitary ceramic
1. Description
Silicon carbide tube is mainly used in the production of aluminum, copper and zinc , as the lining material of the molten pool and electrolytic bath (reduction bath).The side lining of the reduction bath is eroding by aluminum and cryolite (used as additive), but Si3N4 bonded SiC material could not be eroded by aluminum, and do not have chemical reaction with cryolite.So this kind of material is ideal for the lining bricks of the electrolytic bath.In particular this kind of bricks have the excellent properties of high strength, abrasive resistance and nonconductive, so the copolymer (Al2O3 and Cryolite). The copolymer likes protective film to protect the working lining and improve the service life of electrolytic bath of silicon carbide pipe.
2. Characteristics
SiSic tube is also called Reaction bonded Silicon carbide tubem, it can work under 1380℃, why it is widely used in ceramic kiln ?
Because it has very good oxidation and corrosion resistance.And it also has high thermal conductivity and shock resistance, it is very important features. Ceramic kiln need such material for firing.
Besides, it has high mechanical strength and abrasion resistance. Many customer use it in ceramic kiln, it is proved to be the best material for the application.

4. Application
Reaction sintered Silicon carbide tube are used for the loading structure systems of tunnel kiln, shuttle kiln and many other industrial kiln of bearing bracket. Under the condition of high bearing strength, long-term use of deformation, it will not bend and has long using life. It is widely used in ceramic kiln.
5. Package
Packaging of silicon carbide tube: PE bag inside outer carton,finally make the wooden pallet or according to your requirement
Shipping of silicon carbide tube : delivery within 25 days after confirm the order.
