Lub teeb yuag thermal rwb thaiv tsev cov ntaub ntawv muaj qhov porosity siab, tsis tshua muaj qhov ntom ntom thiab tsis tshua muaj thermal conductivity. Ntawm qhov tod tes, nws muaj qhov zoo thermal tsis kam rau kev hloov pauv ntawm qhov kub thiab txias, yog li txo qhov kub ntawm cov khoom siv thermal; Ntawm qhov tod tes, nws lub peev xwm kub yog me me, Tsawg tshav kub cia txhim kho tus nqi siv thiab thermal zog efficiency ntawm cov khoom siv thermal rau lub sij hawm luv luv thiab tsis sib xws. Tsis tas li ntawd, nws tuaj yeem tsim tau tib yam li lwm cov castables, thiab tuaj yeem cam khwb cia tag nrho lossis ua rau hauv prefabricated qhov chaw, uas yooj yim heev rau siv.
Raw cov ntaub ntawv rau lub teeb yuag mullite rwb thaiv tsev castable yog ntxeem tau mullite li grain hais, hmoov thiab additives ntxiv. Qhov loj tshaj particle loj ntawm grain mullite yog 12 hli, kev pabcuam kub tuaj yeem ncav cuag 1350 degree.
Muaj ob lub ntsiab tseem ceeb rau kev xaiv lub teeb yuag castables: ib qho yog qhov ua haujlwm ntawm lub teeb yuag aggregate, thiab lwm yam yog txoj kev khi thiab hom kev khi tus neeg sawv cev. Thaum lub teeb yuag aggregate raug xaiv los tsim lub teeb yuag castable, txoj haujlwm ntawm lub teeb castable nyob ntawm seb hom binder thiab tus nqi ntxiv. Cov tsoos castable castable yog ntxiv 20 mus rau 30 feem pua ntawm cov cement, los yog ntxiv 10 mus rau 15 feem pua ntawm cov iav dej ua cov ntawv khi. Cement thiab dej iav yog siv los ua binders, kom lub zog ntawm cov castable txo qis thaum lub sij hawm cua sov txheej txheem, uas cuam tshuam rau kev siv.
Mullite yog Al2O3-SiO2 theem nrog kev ua tau zoo tshaj plaws nyob rau hauv ntau sab, tshwj xeeb tshaj yog nws cov ci ntsa iab kub uas tsis tshua muaj creep, pab cov mullite tau dav siv nyob rau hauv industrial furnace.
Mullite refractory castable muaj kev thov nruj rau cov neeg sawv cev khi, tus neeg sawv cev yuav tsum tsis txhob cuam tshuam cov khoom zoo ntawm mullite, yog li feem ntau siab alumina hmoov, silica-Alumina gel thiab siab alumina cement yog siv los ua tus neeg sawv cev, kom tau zoo heev mullite refractory castable.
Lub teeb yuag mullite refractory castable yog tsim los ntawm high-strength mullite li aggregate, superfine hmoov thiab compound additives ntxiv. Nws muaj cov yam ntxwv ntawm siab refractoriness, siab zog, tsis tshua muaj thermal conductivity thiab tsawg bulk ceev, uas yuav txo tau lub thermal zog noj ntawm industrial furnaces thiab txo qhov hnyav ntawm lub cub tawg. Ntawm cov khoom siv hluav taws xob kub kub, cov khoom siv raw hauv qab no tuaj yeem siv los ua cov khoom siv rau cov khoom siv kub kub uas siv tau siab tshaj 1200 degree: ntxeem tau clinker los yog cov pob zeb porous xws li mullite, corundum, siab alumina, silica thiab magnesia khoom. Xws li castables tuaj yeem siv ncaj qha rau hauv ob sab ntawm cov cua sov ua haujlwm ntawm 1350 degree.
Siv raws li cov khoom siv hluav taws xob hluav taws xob, xws li rwb thaiv tsev txheej ntawm cov cua sov rauv, annealing rauv, kub moj tej tawg rauv thiab lwm yam .; Lub ntsej muag rwb thaiv tsev txheej ntawm cov raj xa hluav taws xob rau qhov cub tawg, qhov cub kub kub thiab lwm yam .; tsis sib cuag melting qhov chaw ntawm melting rauv thiab yaj thawv khoom, xws li txhuas melting rauv cover thiab lub qhov cub rauv qhov rooj, hluav taws saib xyuas lub qhov rooj hauv ob sab phlu; pa taws chimney thiab pipeline rwb thaiv tsev txheej, xws li cua kub duct hauv ob sab phlu, flue hauv ob sab phlu, thiab lwm yam.
