Muab faib los ntawm cov xim, muaj ob hom silicon carbide:dub silicon carbidethiab ntsuab silicon carbide. Hauv kev lag luam refractory, dub silicon carbide feem ntau siv. Tus editor hauv qab no yuav qhia rau koj txog kev siv cov dub silicon carbide hauv kev lag luam refractory.
1. High-qib refractory khoom dub silicon carbide micropowder, kuj yog thawj-chav kawm silicon carbide. Cov kev cai ntawm silicon carbide muaj pes tsawg leeg ntawm pawg no yog tib yam li cov siv rau abrasives. Feem ntau, thawj silicon carbide feem ntau yog siv los tsim cov khoom lag luam qib siab silicon carbide, xws li recrystallized silicon carbide khoom, roj turbine Cheebtsam, nozzles, hauv ob sab phlu cov ntaub ntawv rau high-temperature blast furnaces, thiab high-temperature kilns. Cheebtsam, refractory saggers, thiab lwm yam., cov ntsiab lus ntawm thawj silicon carbide yog siab, thiab qhov zoo ntawm cov khoom tsim yog zoo.
2. Secondary refractory khoom dub silicon carbide hmoov. Hom silicon carbide no muaj ntau dua 90 feem pua silicon. Nws feem ntau yog siv rau hauv kev tsim cov khoom siv hluav taws xob uas tiv taus qhov nruab nrab thiab siab kub. Silicon carbide muaj cov cua kub zoo, thermal conductivity thiab zoo tshuaj stability.
3. Tsawg-qib refractory khoom dub silicon carbide micropowder, kuj tertiary silicon carbide. Cov pawg no yuav tsum muaj cov ntsiab lus ntawm silicon carbide tsis tsawg dua 83 feem pua, thiab feem ntau yog siv rau hauv ob sab phlu ntawm tapping troughs, ladles, zinc smelting thiab sponge hlau manufacturing industries.
Silicon carbide yog siv los npaj cov khoom cib refractory. Muaj plaub lub thev naus laus zis tseem ceeb rau silicon carbide siv rau hauv cov khoom siv refractory:
1. Oxide bonding: aluminium silicate, silicon dioxide, thiab lwm yam yog siv los ua cov khoom sib txuas.
2. Nitride ua ke: ua ke ntawm silicon nitride, silicon oxynitride thiab sialon.
3. Kev sib xyaw ua ke ntawm tus kheej: ntxiv ib qho kev faib ua feem ntawm graphite thiab hlau silicon, thiab silicon carbide yuav raug tsim los ntawm cov tshuaj tiv thaiv ntawm qhov kub thiab txias.
4. Recrystallization: los ntawm lub hauv paus ntsiab lus ntawm evaporation thiab condensation, silicon carbide hais yog sintered ntawm ultra-siab kub.
