Kodi mitundu ya njerwa zomangira ndi chiyani?
Mitundu ya njerwa zaumbali?
Njerwa zokana ndi zamitundu yosiyanasiyana komanso nthawi zogwiritsira ntchito. Njerwa za Refractory ndi mtundu wazinthu zokanira zomwe zimakhala zotsika mtengo. Ogwiritsa ntchito amatha kusankha njerwa zoyenera zokanira molingana ndi kukula kwake ndi mawonekedwe a chinthucho ndi zida zosiyanasiyana. Kodi machitidwe amitundu yosiyanasiyana ndi ati, ndikuloleni ndikudziwitseni pansipa.
Kampani yathu ili ndi njerwa zomangira, njerwa zopepuka za mullite, njerwa zowotcha kaboni, njerwa za silicon-moon refractory, njerwa zopepuka, ndi njerwa za magnesia carbon refractory.
Mullite lightweight refractory njerwa ndi mkulu-alumina refractory zipangizo ndi mullite monga kristalo gawo lalikulu. Nthawi zambiri, zokhala ndi aluminiyamu zimakhala pakati pa 65% ndi 75%. Kuphatikiza pa mullite, kapangidwe ka mchere wokhala ndi aluminiyamu yotsika imakhala ndi gawo laling’ono la galasi ndi cristobalite; zinthu zapamwamba za alumina zimakhalanso ndi corundum yaying’ono
Kupanga zinthu za kaboni makamaka kumagwiritsa ntchito ng’anjo zowotcha zoyambirira ndi zachiwiri ndi ng’anjo za graphitization, zomwe zimatchedwa ng’anjo zowotcha za kaboni. Zopangira kaboni zowotcha ng’anjo zitha kugawidwa m’ng’anjo zamagulu, ng’anjo zopitilira, ng’anjo zachipinda, ng’anjo za mphete, ng’anjo zamphepo, ng’anjo zozungulira kapena ng’anjo zotsutsa malinga ndi kapangidwe kake ndi njira zogwirira ntchito.
Njerwa za nkhungu za silika zidapangidwa bwino koyambirira kwa zaka za m’ma 1990. Poyamba ankatchedwa HMS high wear-resist njerwa, ndipo mphamvu yawo yokana kuvala ndi yoposa kasanu kuposa ya njerwa za phosphate-bond high-alumina. Pankhani ya gawo lake, ziyenera kukhala zopangidwa ndi silicon carbide-mullite, zomwe zimatchedwa njerwa za silicon mortar.
Njerwa zopepuka zopepuka zimatanthawuza njerwa zosasunthika zomwe zimakhala zosachepera 1.3x103kg/m3. Chifukwa cha mawonekedwe a kachulukidwe kakang’ono, kutsika kwambiri, kutsika kwamafuta, kutsekemera kwabwino kwamafuta ndi mphamvu zina zopondereza, njerwa zopepuka zopepuka zakhala zikugwiritsidwa ntchito kwambiri pazida zochizira kutentha.
Monga chinthu chophatikizika chokanira, njerwa za magnesia-carbon refractory zimagwiritsa ntchito kukana kwamphamvu kwa slag corrosion ya magnesia ndi kutenthetsa kwapamwamba komanso kukulitsa pang’ono kwa kaboni kuti zithandizire kulephera kwa spalling kwa magnesia. Amagwiritsidwa ntchito makamaka pazitsulo zamagetsi zamagetsi.
Njerwa zotsutsa zomwe zatchulidwa pamwambapa zamitundu yosiyanasiyana ndi zida zosiyanasiyana zimakhala ndi mitengo yosiyana. The serviceability wa njerwa refractory akadali yaitali kwambiri. Imalimbana ndi kutentha kwambiri komanso kuyabwa. Njerwa zabwino zokana zimatha kugwiritsidwa ntchito kwa nthawi yayitali. Kamodzi, mtundu wa njerwa zowumbidwa ndi kampani yathu Ndiwotsimikizika, nkhani zamitengo zatsatanetsatane zitha kufunsidwa pa intaneti, mayankho opangira makonda anu, ndikudzipereka kuti akutumikireni.
