Nyob rau hauv xyoo tas los no, daim ntawv thov ntawmcov kav dej ceramic uas tsis yooj yim hnavtau dhau los ua ntau dua thiab ntau dua, tshwj xeeb tshaj yog nyob rau hauv kev lag luam niaj hnub no. Cov kav dej ceramic uas tsis yooj yim hnav muaj cov yam ntxwv zoo heev ntawm kev tiv taus cua sov, kev tiv taus corrosion thiab kev tiv taus hnav, thiab tau siv dav hauv metallurgy, thermal fais fab, hlau, cement thiab lwm yam teb ntawm kev thauj mus los ntawm cov thee pulverized thiab lwm yam kev thauj mus los hauv xov xwm. Feem ntau, cov txheej txheem vuam sab hauv thiab sab nraud ob txheej siv, thiab qhov zoo ntawm qhov vuam kuj tau lees paub. Hauv cov txheej txheem vuam, txhua yam tsis zoo, xws li kab nrib pleb, qhov hws thiab cov qhov txhab tsis tuaj yeem tshwm sim. Tom qab vuam tiav, lub zog ntawm qhov vuam yuav tsum muaj peev xwm txuas ntxiv ua haujlwm yam tsis muaj kev xau.
Yuav kom txhim kho kev thauj mus los ntawm cov kav dej, cov lauj kaub ceramic uas tsis yooj yim hnav thiab cov nozzles tuaj yeem siv rau hauv cov kav dej thee uas raug tsoo. Cov coefficient ntawm kev nthuav dav thermal ntawm cov lauj kaub ceramic thiab cov kav dej no zoo ib yam li cov kav dej hmoov, thiab yuav tsis raug kev txom nyem los ntawm kev nthuav dav thiab kev tawg vim qhov kub thiab txias ntxuav. Tsis tas li ntawd, kev teeb tsa cov ceramics uas tsis yooj yim hnav yuav tsum tau nruj nreem rau ntawm phab ntsa tuab kom txhim kho kev hnav tsis yooj yim hnav. Qhov chaw du ntawm cov ceramic tuaj yeem txo qhov kev tiv thaiv ntawm cov kav dej thiab txhim kho lub peev xwm thauj khoom.
Rau cov kav dej loj, cov nplaum ceramic liner feem ntau yog siv los txhim kho cov kav dej ceramic uas tsis yooj yim hnav, thiab cov duab ntawm cov ceramic lining tuaj yeem xaiv tau raws li qhov chaw ua haujlwm tiag tiag, xws li xaiv cov nplaum ceramic uas tsis yooj yim hnav lossis vuam cov ceramic uas tsis yooj yim hnav raws li qhov kub, kom ntseeg tau tias qhov kub yuav tsis muaj kev cuam tshuam ntau dhau rau cov kav dej. Rau cov kav dej me me, cov nplhaib ceramic kuj tseem tuaj yeem xaiv ua cov kav dej liners rau kev txhim kho yooj yim.
Hauv kev siv tiag tiag, cov kav dej ceramic uas tiv taus hnav feem ntau yog siv rau hauv metallurgy, thermal fais fab, hlau, cement thiab lwm yam khoom siv, tshwj xeeb tshaj yog cov khoom siv uas raug ntxuav hmoov av lossis cov khoom siv hnyav. Piv txwv li, cov kav dej ceramic uas tiv taus hnav tuaj yeem xaiv rau cov kav dej xa tawm ntawm lub Hoobkas thee, cov khoom siv tshem tawm plua plav ntawm lub Hoobkas smelter, cov kav dej cua, kev thauj mus los ntawm thee thiab cov tshuab thauj tshauv. Rau cov khoom siv hauv qhov kub siab, cov kav dej ceramic uas tiv taus hnav kuj tseem siv tau ua cov kav dej kub siab zoo.
Cov yeeb nkab ceramic uas tsis hnav-resistant yog qhov tshwm sim ntau dua thiab ntau dua hauv kev lag luam niaj hnub no, nws muaj cov yam ntxwv ntawm kev hnav-resistant, corrosion-resistant thiab kub-resistant, uas tuaj yeem ua rau lub neej ua haujlwm ntawm cov khoom siv ntev dua thiab txhim kho kev ua haujlwm ntawm kev thauj khoom siv. Nrog rau kev txhim kho thev naus laus zis, kev tshawb fawb thiab kev siv cov yeeb nkab ceramic uas tsis hnav-resistant tseem muaj kev cia siab zoo rau kev txhim kho, thiab tseem coj kev yooj yim dua thiab kev lag luam zoo dua rau kev lag luam.
