Si3N4 Silicon Nitride protection tubes/pipes  

Application:1.the production of aluminum, copper and zinc.

                     2.the lining material of the molten pool and electrolytic bath (reduction bath).

                     3.The side lining of the reduction is eroding by aluminumand cryolite (used as additive )

                     4. the lining bricks of the electrolytic bath.

Advantage:  Silicon Nitride protection tubes have the advantages of 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. At the same time, the Si3N4 bonded SiC bricks have lower thermal conductivity than silicon bricks, so they can reduce the thickness of the side wall or input higher power to expanse the loading capacity of the electrolytic bath, and to increase the output. Because of the high resistivity of the material, it can reduce the power consumption of the side -wall about 15%, saving energy and protecting environment .
