Txawm hais tias muaj qee cov kev cai rau lub ci ntawm refractory castables, tab sis tsis muaj tus nqi ruaj khov rau lub sijhawm ci. Nws yog ua tib zoo tswj hwm raws li qhov xwm txheej tiag tiag, thiab lub sijhawm ci yuav tsum txiav txim siab nkag siab ntau yam xws li ntau hom kev hloov pauv, siv cov tuab ntawm cov khoom tuab.
Yam Refractory Castables, Refractory Cib, lossis Furraces sib xyaw nrog ntau cov ntaub ntawv: muaj cov pa hluav taws xob, thiab coj mus ua silt. Lub hom phiaj tseem ceeb yog ua kom muaj kev tso dej khov kho thiab zam cov khoom tawg thaum siv.
Refractory Castables kuj yuav tsum tau kho tag nrho thiab ib txwm qhuav ua ntej ci, feem ntau yog rau 3 hnub tom qab kev tsim kho kom ua tau kom muaj zog txaus tom qab hais tias yuav ua rau pom tseeb. Thaum lub sij hawm ci txheej txheem cas los ntawm Refractory castables, qhov ntsuas kub yuav tsum cia kom loj ntshis rau rwb thaiv tsev, thiab yuav tsis muaj kev hloov pauv lossis qhov kub thiab txias poob. Yog tias qhov ntsuas kub thiab txias, nws yuav ua rau kev puas tsuaj rau cov txheej txheem refractory castaber.
Feem ntau, lub sijhawm ci rau cov refractory castables yog 5 {}}}}}}}}}}} Txheem Castabe nws tuaj yeem ua nyob rau hauv 1 hnub. Cov yas castables tuaj yeem ua kom sov thiab siv nrog lub cub tawg thiab cov khoom ua kom zoo dua qub thaum lub sijhawm tsim kho, nws yuav tsum ua hauv 7-10 hnub.
Txawm li cas los xij, tsis hais txog ntawm cov hnub ntawm ci, lub sijhawm tseem ceeb tshaj plaws yog nyob rau ntawm cov refinatory ntawm kev tawg thiab tusyees, zam kev tawg ntawm lub siab sai.
Thaum qhov kub thiab txias nyob nruab nrab ntawm 150-3 degree, dej dawb ntawm Refractory Castables yuav tsum tau decomposed thiab lub cev qhuav dej, thiab rwb thaiv tsev rau 24-48 teev. Thaum qhov kub thiab txias yog nyob nruab nrab ntawm 350-400 degree, rwb thaiv tsev rau 24 teev yog xav tau. Thaum qhov ntsuas kub ntawm 400-600 degree, rwb thaiv tsev rau 24-48 teev yog tau. 600} Cov sij hawm thaum lub sij hawm siv lead ua yog muab pov tseg thiab pib tsim lub zog. Tom qab 600 degree, cov cua sov tus nqi yuav ua tau zoo ua ntej muab coj mus siv.
Ntxiv rau kev ua kom tiav qhov kev nkhaus cua sov, nws tseem tsim nyog tau saib ib puag ncig 300 degree. Yog tias tseem muaj ntau qhov ntau ntawm cov pa roj nyob rau lub sijhawm no, lub sijhawm rwb thaiv tsev yuav tsum txuas ntxiv. Yuav siv cov ntawv huv si los xyuas seb puas tseem muaj dej vapor ua kom cov pa dej hauv cov pa taws ntawm lub manhole lossis qhov rooj los txiav txim.
Qhov kub sib txawv ntawm refractory castables nyob rau lub caij ntuj no thiab lub caij ntuj sov yog qhov tseem ceeb, thiab kev kho kom haum yuav tsum ua raws li qhov tseeb.
