Refractory castable yog cov khoom siv hauv tsev tsom rau qhov chaw kub kub. Nws cov khoom tshwj xeeb tso cai rau nws tiv taus qhov kub thiab txias, thaum lwm yam khoom tshwj xeeb ua rau nws zoo rau kev siv hauv ntau daim ntawv thov kev lag luam.
Cov yam ntxwv ntawm castables
Ua ntej, refractory castables muaj qhov kub thiab txias ua haujlwm zoo heev thiab feem ntau tuaj yeem tiv taus qhov kub thiab txias tshaj 3000 degree F. Nws yog cov khoom siv hauv tsev uas tsim nyog rau txhua qhov chaw kub kub, txawm tias nws yog nyob rau hauv lub cub tawg lossis lwm yam kub kub. xws li lub qhov cub. Nyob rau tib lub sijhawm, castables refractory kuj tseem muaj cov tshuaj tiv thaiv thiab tuaj yeem tiv thaiv kev yaig ntawm cov tshuaj lom neeg, xws li acids, alkalis, cov kuab tshuaj, thiab lwm yam. Thaum kawg, castables muaj cov khoom zoo xws li kev sib txhuam thiab hnav tsis kam, ua rau lawv siv dav hauv kev lag luam.
Kev siv cov castables
Refractory castables tuaj yeem siv rau hauv ntau qhov chaw kub kub, xws li metallurgy, steel, aluminium, cement, hluav taws xob, petrochemicals, kev tsim kho, thiab lwm yam. Nws yog dav siv hauv qhov cub, boilers, kub moj tej tawg furnaces, hluav taws xob furnaces, converters, dej kub. furnaces, iav furnaces, ceramic furnaces, thiab lwm yam nyob rau hauv kub kub ib puag ncig. Txawm hais tias siv nyob rau hauv ib puag ncig corrosive ntawm qhov kub thiab txias los yog lwm yam kev siv nyuaj, cov khoom siv tshwj xeeb no muaj peev xwm loj rau kev loj hlob hauv ntau qhov chaw.
Kev tsim cov castables
Refractory castables yog tsim los ntawm kev sib xyaw ntau yam ntawm cov khoom siv raw nrog cov dej kom raug. Cov ntaub ntawv nyoos no muaj xws li ntuj quartz xuab zeb, ntau hom alumina, chromium, iav hlaws, magnesium oxide, thiab lwm yam. Cov ntaub ntawv raw yog tov rau hauv slurry, stirred ntawm kev kub ceev, thiab ces poured rau hauv pwm. Lub slurry hardens nyob rau hauv pwm, thaum lub sij hawm uas nws tsim ib tug heev nyuaj thiab check refractory castable.
Hauv cov ntsiab lus, refractory castables yog dav siv nyob rau hauv ntau qhov chaw kub. Nws cov khoom zoo heev ua rau nws yog thawj qhov kev xaiv rau cov khoom siv hauv tsev kub. Nws cov khoom tshwj xeeb muaj pes tsawg leeg thiab kev tsim khoom zoo kuj tau ua rau nws daim ntawv thov kev lag luam txuas ntxiv mus ntxiv. Peb muaj kev ntseeg siab rau yav tom ntej ntawm cov khoom siv hauv tsev no.
