Cov txheej txheem ntawm kev tua hluav tawsRefractor CibXws li peb qhov kev ua tiav: ntsaws cov kiln, tua cov kiln thiab unloading lub Kiln.
1: Thauj cov Kiln
Qhov thiaj li -}}}} hu ua chaw thau khoom ntawm cov txheej txheem kev ua haujlwm ntawm lub kiln thiab cov kev xav tau ntawm lub zog thermal thaum cov khoom raug rho tawm haujlwm. Rau qhov cub bilns, nws tseem hu ua Chaw thau khoom (Kiln) tsheb.
1) txiav txim rau KILN thauj qhov siab thiab cov kev thauj khoom raws li kev sib txawv cib. Feem ntau, lub Kiln loading qhov siab ntawm Magnesia cib thiab ua ntej-} al} Ale} Cov Cib Zoo yog 1 ~ 1.1m; Silica Cib yog 1 ~ 1.7m; Cov xuab zeb av nplaum yog nruab nrab ntawm ob. Feem ntau ntawm cov kev thauj khoom cib thauj khoom ncaj qha txais tiaj loading, Silica Cib yuav tsum ntsug loading thiab av nplaum cib cib chaw thau khoom.
2) Raws li cov hom sib txawv sib txawv cov hom, txiav txim siab lub KILN thauj cov sib piv ntawm cov cib dav dav thiab tshwj xeeb {1} zoo li cov cib. Feem ntau, cov piv ntawm tshwj xeeb {{3} Zoo li cib rau General Bricks ntawm tib lubil lub tsheb yog li 4: 6. Nyob rau tib lub sijhawm, nws tseem tsim nyog los txiav txim rau KILN thauj txoj haujlwm ntawm ntau hom sib txawv raws li kev sib txawv cib. Feem ntau, cov qauv sib zog thiab cov pob zeb dav dav tau nruab rau hauv qab, thiab tshwj xeeb {{{} zoo li cov thwv cib nruab rau sab saum toj. Qee qhov tshwj xeeb - zoo li cov cib lossis cov pob zeb uas yooj yim rau tawg thaum tua hluav taws tau ntim (cib qhwv hauv cov thwv cib).
3) Raws li qhov ua ntej ntawm kev ua kom zoo nkauj, nce cov cib loading ntom ntom (piv txwv li tus naj npawb ntawm cov cib thauj tog ib lub tsheb) kom nce roj. Tsim ib daim duab thauj khoom zoo tsim nyog Yog li ntawd, hauv kev tsim cov ntaub ntawv refractory, qhov yooj yim yuav tsum tau ua kom muaj kev sib tsoo, ruaj khov, kom txo cov distortion ntawm cov khoom siv rho tawm haujlwm. Txhawm rau kom tau raws li cov txheej txheem sau saum toj no, ib txheej ntawm cov xuab zeb nrog cov me me ntawm 0.5 rau ib qho me me sprinkled ntawm txhua txheej ntawm kev thauj khoom thaum thauj khoom KILN. Cov khoom lag luam ntawm cov khoom sib txawv muaj qhov sib txawv rau hauv cov xuab zeb. Feem ntau, av nplaum cib thiab siab {{alumina cib siv chips silica xuab zeb, bauxite, mov husks lossis mov husk tshauv; Silica bricks siv pov tseg silica cib xuab zeb lossis silica xuab zeb; Thiab Magnesia cib siv cov xuab zeb los yog chomium ore xuab zeb.
2: tua hluav taws
Thaum lub sij hawm tua hluav taws, lub cib tsis muaj kev sib tw ntawm lub cev thiab tshuaj tsw qab, ua rau nws lub zog, ua rau nws lub zog, ruaj khov rau sab nraud sab nraud. Tag nrho cov txheej txheem tua hluav taws tuaj yeem faib ua peb theem:
(1) Cov cua sov, uas yog los ntawm lub sijhawm nkag mus rau hauv kiln lossis raug rau lub sijhawm thaum cov khoom lag luam nce siab kub tshaj plaws. Raws li qhov kub nce ntxiv, cov theem ua kua tsim kub thiab lub cev theem hluav taws xob hluavtaws kub tau mus txog. Vim tias qhov diffusion, ntws, kev sib txawv, nag lossis daus thiab cov khoom siv ua ke, nce nws lub zog, txo nws cov porosity, thiab seem yog sintereded.
(2) Cov theem rwb thaiv tsev ntawm qhov kub tshaj plaws kub tshaj plaws. Ntau yam kev tawm tsam hauv lub cev ntsuab zoo li ua tiav thiab txaus ntawm theem ua kua nce ntxiv, cov Crystal theem hlob ntxiv, thiab lub cev ntsuab nce mus txog Densification. Thaum lub sij hawm tua hluav taws, tsis yog tsuas yog saum npoo ntawm cov khoom yuav tsum tau tua hluav taws kub, tab sis sab hauv cov khoom yuav tsum tau tua hluav taws kub. Cov txheej txheem cua sov no tau ua tiav los ntawm kev hloov pauv tshav kub, uas yuav tsum muaj qee lub sijhawm. Nws tuaj yeem pom tau tias cov khoom loj dua thiab ntau dua lub Kiln ntom, lub sijhawm ntev dua. Tsis tas li ntawd, vim qhov ntsuas kub tsis sib xws ntawm ntau qhov chaw hauv cov kiln, qee qhov nyiaj ntawm cov sijhawm rwb thaiv tsev tseem yuav tsum tau ua.
(3) Cov theem cua txias yog hais txog lub sijhawm los ntawm qhov kub tshaj plaws kub tshaj rau KILN tawm qhov kub. Nyob rau hauv theem no, cov qauv hloov qauv thiab tshuaj hloov ntawm cov khoom ntawm qhov kub kub yog qhov pib. Nyob rau theem pib ntawm qib no, qee qhov kev hloov pauv ntawm lub cev thiab tshuaj lom neeg ntawm cov khoom muaju, solidification ntawm cov iav theem, thiab tiam ntawm microcracks. Lub kaw lus txias yuav cuam tshuam rau cov khoom siv lub cev ntawm cov khoom lag luam, xws li lub zog thiab thermal poob siab kuj.
Txhawm rau tsim tawm cov khoom hluav taws xob ntawm ntau cov khoom siv hluav taws xob ntawm txhua cov khoom yuav tsum tau txiav txim siab ua ntej, suav nrog: qhov kev kub siab tshaj plaws; cov cua kub nyob hauv txhua theem; lub sijhawm rwb thaiv tsev nyob ntawm qhov kub siab tshaj plaws; Tus nqi txias thaum cov khoom txias; Cov Khoom Cua Cua nyob hauv Kiln hauv cov theem saum toj no. Cov txheej txheem tua hluav taws ntawm cov khoom siv hluav taws xob tuaj yeem ua tiav los ntawm ob lub zog cua sov, uas yog, cov khoom raug rho tawm haujlwm ntawm qis dua, lossis ntawm qhov kub siab dua rau lub sijhawm luv. Tab sis qhov tseeb, vim kev hloov cua sov qeeb hauv cov khoom hauv cov khoom hauv cov khoom hauv lub Kiln, muaj qhov txwv tsis pub siv cov khoom siv ceev ceev. Lub cev tua hluav taws xob ntawm cov khoom lag luam refractory tsis yog tsuas muaj feem nrog ntau yam, cov qauv thiab qhov loj me uas cuam tshuam nrog cov khoom tua hluav taws. Piv txwv li, ib qho dej ntws loj yuav tsum tau txo cov cua sov npaum li cas thiab lub sijhawm rwb thaiv tsev ntev kom ntseeg tau tias qhov kub ntawm lub refractory cib. Lub cev tua hluav taws tsis tsim nyog yuav nce cov nqi ntawm cov khoom seem thiab txo cov khoom lag luam zoo. Kev tua hluav taws uas tsim hluav taws uas tsim nyog raws li kev taw qhia thiab cov kev paub dhau los.
3. Kiln tawm
Kiln tawm yog cov txheej txheem ntawm kev coj cov khoom tua hluav taws tawm ntawm cov kiln tom qab txias, lossis thim rov qab los ntawm lub tsheb mev. Qhov zoo ntawm KILN kev ua haujlwm tawm tau muaj qhov cuam tshuam ncaj qha rau cov tsos zoo ntawm cov khoom tiav ntawm cov khoom tiav. Hauv cov ntaub ntawv refractory, cov ntsiab lus hauv qab no yuav tsum tau them nyiaj rau hauv Kiln Daws Kev Ua Haujlwm: (1) Thaum noj cov khoom noj kom tsis txhob muaj qhov tshwm sim los ntawm kev ua haujlwm tsis ncaj ncees. (2) cov khoom lag luam nrog cov lej sib txawv yuav tsum tau sib cais, qhov ntawd yog qhov ua rau muaj kev sib txawv thaum lub sijhawm kuaj xyuas thiab xaiv cov khoom tiav. Vim tias cov khoom ntawm qee cov khoom lag luam nrog cov lej cib sib txawv tuaj yeem yog qhov zoo ib yam, tab sis muaj qhov sib txawv me me hauv qhov loj me (ob peb hli lossis ib lub hli los yog ib lub hli twg). Yog tias lawv tau sib xyaw rau ntawm lub rooj zaum cib, nws yog ib qho yooj yim rau kev ua yuam kev ntawm ib tus lej cib rau cov pov tseg thaum xaiv, uas yuav tsis tsuas yog ua rau kev nkim, tab sis kuj cuam tshuam rau kev siv. (3) Cov cuab yeej siv cib (Cib Racks, cib, thiab lwm yam) yuav tsum tau txheeb thiab muab tso rau txuas ntxiv thaum thauj khoom KILN. (4) Ua tib zoo saib xyuas kom muaj kev nyab xeeb thiab kev tiv thaiv kev ua haujlwm thaum noj tawm lub Kiln thiab thauj cov cib recractical.
