    High temperature tolerance Si3N4 Thermocouple Components Protection Silicon Nitride tube

     

    Description:

     

    1) Si3N4bondedd by adding industrial silicon paste into artificial aggregate.

     

    2) Si3N4-SiC Thermocouple Protection tube Silicon nitride (Si3N4) bonded silicon carbide (SiC) material is produced by adding industrial silicon paste into artificial aggregate. Under high temperature, Si and N2 reacts with the formula of 2N2+3Si=Si3N4, Si3N4 bonded Sic material is formed by bonding SiC particles tightly.

     

    3) Si3N4 bonded SiC material is an excellent refractory with the original properties of SiC. The material has quite high strength even under the temperature of 1700.C has properties of creep deformation resistance and anti-chemical erosion, and has excellent thermal conductivity and wear-resistance. Comparing with other several bonded SiC materials, Si3N4 bonded SiC material has attracted more and more attention.

     

    Specification:

     

    1) Si3N4 Bonded SiC material 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.

     

    2) 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.

     

    3) 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.

    Application

     

    1) With the circulating fluidized bed (CFB) boiler in the popularity of electric power industry, the ideal of high temperature resistant, corrosion resistant, wear resistant silicon nitride thermocouple protection tube to monitor furnace temperatureis the top priority.

     

    2) Silicon nitride thermocouple protection tube is for cement dryprocess winding kiln production line with the relevant tertiary cylinder, four cylinder, five cylinder cone temperature, and central, preheater smoke of decomposing furnace, kiln hood temperature measuring characteristics to applicate, for ordinary wear-resistant silicon nitride thermocouple protection tube material has bad quality problem, can meet the special high temperature resistant to erosion in temperature conditions, leading to shorter service life of thermocouple,high product value and need has frequent replacement and transmission signal is not guaranteed, instrument is in the alert status for a long time, at the same time adds a lot od workload to instrument maintenance, silicon nitride thermocouple protection tube can better solve the universal problems existing in the cement industry;
