Oxidation resistant refractory high strength SiSiC Silicon carbide beam
1. Sintering Theory
Silicon carbide beam 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.
Oxidation resistant SiSiC silicon carbide ceramic beam with low price are used for the loading structure systems of tunnel kilns, shuttle kilns and many other industrial kilns. RBSIC ceramic cross beams have higher strength and there are no deformations even at high emperatures, and also the beams display ver long service life. They are the most suitable kiln furnature for sanitarywear and electrical porcelain applications.Besides, RBSIC beams have excellent thermal conductivity, so it is available to save energy with less weight of the kiln car.

The reaction bonded silicion carbide ceramic is an ideal wear resistant material, which is especially suitable for the strong abrasive, coarse particles, classification, concentration, dehydration and other operations. Due to the above properties, the reaction bonded silicon carbide wear resistant ceramic tubes can effectively protect the part from high wear so as to prolong the service life of the equipment.
3. Main Application
