Njerwa za Sillimanite ndi mtundu wa njerwa zapamwamba kwambiri zokanira zokhala ndi refractoriness yapamwamba ya 1770 ~ 1830 ℃ komanso kukana kwakukulu pansi pa katundu wa 1500 ~ 1650 ℃, omwe katundu wake wakuthupi ndi mankhwala ndi wabwino kuposa njerwa zapamwamba za alumina. Sillimanite imasandulika kukhala mullite ndi silicon dioxide yaulere pambuyo pa kutentha kwakukulu. Njerwa za Sillimanite refractory nthawi zambiri zimagwiritsa ntchito njira yopangira kutentha kwambiri komanso kusakaniza matope.
Njerwa yamoto ya Sillimanite ndi ya osalowerera ndale. Njerwa ya Sillimanite imapangidwa ndi mchere wa sillimante, womwe umatha kusintha kukhala mullite ndi silika waulere pambuyo pa kutentha kwakukulu. njerwa ya sillimanite refractory imapangidwa ndi njira zowotcha ndi kuponyera kutentha kwambiri.
Njerwa za Sillimanite zimapangidwa ndi zinthu zazikulu za sillimanite, sillimanite ndi mtundu wa zida zopangira zopangira zopangira ndipo zimagwiritsidwa ntchito popanga njerwa zapamwamba za alumina zotsika pang'ono, kukana kwakukulu pansi pa katundu, kugwedezeka kwakukulu kwa kutentha komanso kukula pang'ono, ndi ng'anjo yamoto. sillimanite imatha kusinthidwa kukhala mullite ndi silicon dioxide yaulere kudzera mukuwombera kutentha kwambiri. Njerwa za sillimanite zomangira zinthu zakuthupi ndi zamankhwala ndizabwino kuposa njerwa zazitali za alumina. Sillimanite moto njerwa refractoriness ndi 1770 ~ 1830 ℃ ndi zikuoneka koyamba kufewetsa kutentha ndi 1500 ~ 1650 ℃.

Njerwa za Sillimanite zimagwiritsidwa ntchito makamaka poyatsa ng'anjo, ng'anjo yamoto, chitsulo notch ndi tuyere ya ng'anjo yophulika, ndikumangirira pakhosi kwa ng'anjo yamagalasi. komanso njerwa ya sillimanite refractory imagwiritsidwa ntchito monyanyira m'makampani opanga magalasi, mafakitale a simenti, mafakitale azitsulo ndi zitsulo zosakhala ndi ferrous ndikutenthetsa ndi kukana bwino kwa katundu wotenthetsera kutentha.
Fakitale ya Rongsheng refractory yakhala ikuumirira kuti pakhale njerwa zapamwamba za sillimanite kwazaka zambiri. Kampani ya RS ili ndi chidziwitso chokwanira chopanga komanso ukadaulo wapamwamba wopanga. alinso ndi injiniya waluso kuti akupatseni upangiri waukadaulo pakugwiritsa ntchito kwanu kwenikweni. Ngati muli ndi funso lokhudza njerwa ya sillimanite refractory, chonde titumizireni kuti mudziwe zambiri zaukadaulo, malonda athu adzakuyankhani nthawi yoyamba.
