Hauv cov chaw ua lag luam uas muaj qhov kub siab—txij li cov cub tawg hlau mus rau cov cub tawg cement—cov cib refractoryyog cov khoom tseem ceeb uas ua kom muaj kev nyab xeeb thiab ruaj khov ntawm cov ntaub hauv lub cub tawg. Raws li "lub hauv paus" ntawm cov qauv cub tawg hauv kev lag luam, cov cib tshwj xeeb no ua lub luag haujlwm tseem ceeb hauv kev khi thiab txhawb nqa cov ntaub hauv cov khoom siv refractory, tiv thaiv kev sib cais thiab kev tawg hauv qab qhov kub thiab kev ntxhov siab ntawm lub tshuab. Kev xaiv cov cib refractory zoo tsis yog tsuas yog ua kom lub cub tawg ntev dua xwb tab sis kuj txo cov nqi kho thiab txhim kho kev ua haujlwm zoo.
Cov cib ntsa refractory tau tsim los kom tiv taus qhov kub thiab txias ntawm 1200 ℃ txog 1800 ℃ nyob ntawm cov khoom siv. Ua los ntawm cov khoom siv raw zoo xws li high-alumina, corundum, thiab silicon carbide, lawv muaj kev tiv taus thermal shock zoo heev, muaj zog kho tshuab siab, thiab muaj zog tiv taus corrosion tiv thaiv lub cub tawg slag thiab cov pa flue. Lawv cov qauv tsim tshwj xeeb - nrog rau qhov kawg dai rau kev txuas rau lub plhaub hlau cub tawg thiab qhov kawg anchoring embedded hauv refractory linings - tsim kev sib txuas ruaj khov uas faib cov thermal stress sib npaug, zam kev tawg thiab tev tawm.
Qhov ua tau ntau yam ntawm cov cib refractory anchor ua rau lawv haum rau ntau yam kev siv hauv kev lag luam. Lawv siv dav hauv metallurgy (blast furnaces, hot stoves), cov ntaub ntawv tsim kho (cement rotary kilns, glass furnaces), petrochemicals (cracking furnaces, gasifiers), thiab fais fab (boilers, incinerators). Txawm hais tias rau lub qhov cub, phab ntsa, lossis lwm qhov chaw kub siab, cov cib no muab kev txhawb nqa txhim khu kev qha, ua kom ntseeg tau tias cov ntaub ntawv refractory zoo txawm tias nyob hauv kev kub ntxhov ntau zaus.
Piv rau cov khoom siv refractory ib txwm muaj, peb cov cib refractory anchor muaj cov txiaj ntsig sib txawv: kev ua kom sov tsawg los txo qhov poob cua sov, cov duab thiab qhov loj me tuaj yeem hloov kho kom haum rau ntau hom kev tsim cub tawg, thiab kev teeb tsa yooj yim thiab hloov pauv kom txo qhov tsis ua haujlwm. Peb ua raws li cov qauv tswj hwm zoo nruj, xyuas kom meej tias txhua lub cib ua tau raws li cov kev cai ntawm kev lag luam rau lub zog, kev ruaj khov, thiab kev siv tau ntev. Peb cov khoom tsis yog tsuas yog txhim kho kev nyab xeeb ntawm cub tawg xwb tab sis kuj pab txhawb kev txuag hluav taws xob los ntawm kev txo cov cua sov pov tseg.
Nyob rau hauv kev lag luam niaj hnub no uas muaj kev sib tw heev, kev nqis peev rau cov cib ntsa uas ua los ntawm cov khoom siv refractory zoo yog qhov kev xaiv zoo rau cov tuam txhab uas tab tom nrhiav kev ruaj khov rau kev ua haujlwm mus sij hawm ntev. Txawm hais tias koj xav tau cov cib ntsa uas yog tus qauv lossis tus qauv, peb muab cov kev daws teeb meem uas tsim tshwj xeeb los ua kom tau raws li koj cov kev xav tau tshwj xeeb rau kev siv rau qhov kub siab. Ntseeg peb cov cib ntsa uas ua los ntawm cov khoom siv refractory los tiv thaiv koj lub cub tawg thiab tsav kev tsim khoom zoo thiab muaj kev nyab xeeb.
