Qhov hluav taws kub kub ntawm cib thiab pobzeb tiaj tiaj-sab saum toj qhov cub yog qis dua 1200 degree, thiab qhov kub siab tshaj plaws hauv qhov hluav taws xob dav dav yog nyob ib puag ncig 1100 degree. Raws li kev tua hluav taws, lub kiln feem ntau muab faib ua peb thaj chaw: thaj chaw ua ntej cua sov, thaj chaw tua hluav taws, thiab thaj chaw txias. Qhov kub ntawm txhua cheeb tsam kuj txawv, yog li qhov yuav tsum tau ua rau cov ntsiab lus ntawm aluminium thiab refractoriness ntawmrefractory brickskuj txawv.
Txhawm rau txo cov cua sov xa mus rau sab nraud los ntawm phab ntsa, qhov pom meej porosity ntawm cov ntaub ntawv refractory kuj tau hais meej meej raws li qhov taw qhia tseem ceeb. Qhov pom meej porosity yog qhov taw qhia tseem ceeb rau kev ntsuas qhov zoo ntawm cov khoom siv refractory lossis cov khoom. Nws tsis tsuas yog qhia txog qhov ntom ntawm cov khoom siv refractory, tab sis kuj qhia txog seb nws txoj kev tsim khoom tsim nyog. Ntxiv nrog rau cov khoom siv hluav taws xob sib sib zog nqus, cov khoom siv tsis tshua muaj porosity los yog cov khoom lag luam muaj txiaj ntsig zoo rau kev txhim kho cov khoom zoo, txhim kho lub zog ntawm cov khoom, txo qhov chaw ntawm qhov chaw nyob rau hauv kev sib cuag nrog slag, thiab ncua kev pab cuam lub neej.
Lub zog compressive ntawm cov ntaub ntawv refractory nyob rau hauv chav tsev kub yog siab heev, thiab lawv yuav deform thaum raug siab thaum kub nce. Rau lub qhov cub, qhov degree ntawm deformation ntawm cov ntaub ntawv refractory yuav tsum tau ua kom tau raws li cov kev xav tau ntau lawm thaum qhov kub ntawm qhov hluav taws kub yog siab tshaj, uas yog, lub load softening point ntawm refractory cov ntaub ntawv yuav tsum tau raws li cov kev xav tau tsim.
Txhawm rau txo cov cua sov ntawm lub thawv ntim phab ntsa, cov phab ntsa sab hauv thiab sab nrauv ntawm cov phab ntsa kiln yog tsim nrog cov khoom siv hluav taws xob sib xws xws li rwb thaiv tsev cib, ntxhia wool interlayers, thiab perlite pob zeb thiab lwm yam khoom siv rwb thaiv tsev. Hom thiab thickness ntawm txhua txheej ntawm txhua seem ntawm ib lub kiln yog txiav txim raws li qhov kub thiab txias ntawm seem.
Kev ntsuas ntsuas ntawm refractory cib hauv cib thiab pobzeb qhov cub. Feem ntau cov qauv tsim thiab kev tsim kho tseem siv cov ntsuas saum toj no raws li tus qauv rau kev sim seb puas muaj hluav taws kub refractory cib ua tau raws li cov kev cai rau kev siv qhov cub. Tam sim no, cov ntsuas ntsuas ntawm refractories bricks tau hloov kho rau ntau yam ntsuas xws li compressive zog thiab load softening point.
Tam sim no, kev tsim kho ntawm qhov av kilns tau pib siv lub ru tsev tiaj tus. Tam sim no, lub qhov cub nrog cov txheej txheem qab nthab tau muab faib ua ob lub qauv, ib qho yog cov qauv paj rwb tag nrho; lwm qhov yog ib qho kev sib xyaw ua ke ntawm suspended qab nthab cib thiab paj rwb. Ntawm no peb feem ntau piav qhia txog cov kev cai yooj yim rau kev tshem tawm qab nthab cib raws li hauv qab no:
Kev sib koom ua ke ntawm lub qab nthab refractories cib: Kev sib koom ua ke ntawm lub qab nthab cib yog qhov nyuaj, thiab kev sib koom ua ke ntawm cov npoo thiab cov ces kaum ua rau lub ru tsev kiln ruaj khov thiab tiaj tus thiab tsim ib lub foob, uas yog yooj yim dua rau kev siv los ua ib lub ru tsev rwb thaiv tsev txheej. Tam sim no, ntau lub tsev tsim qauv muaj ntau hom kev sib txawv thiab kev txheeb xyuas cov cib qab nthab, thiab cov cib tshwj xeeb yuav tsum tau txiav txim siab raws li hom kiln.
Lub zog ntawm cov pob zeb refractory raug tshem tawm: Lub zog yuav tsum muaj ntawm cov pob zeb uas raug tshem tawm ntawm cov kab hlau steel yog nruj heev. Suspended bricks yeej dais lub load ntawm tag nrho cov ntaub ntawv rwb thaiv tsev ntawm lub ru tsev kiln.
Precision yuav tsum tau rau kev tsim kho ntawm suspended qab nthab refractory hluav taws cib: Lub suspended qab nthab yog ib tug tseem ceeb project ntawm lub roasting kiln. Qhov zoo ntawm lub qab nthab tshem tawm ncaj qha cuam tshuam qhov zoo ntawm tag nrho cov kiln thiab koom nrog tag nrho cov kab ntau lawm. Ua ntej ntawm tag nrho cov, tshem tawm lub qab nthab cib thiab tshem tawm lub qab nthab panels yuav tsum tau soj ntsuam tam sim ntawd tom qab nkag mus rau hauv lub site, thiab lub suspended qab nthab ua hauj lwm yuav ua tau tsuas yog tom qab dhau qhov kev tshuaj ntsuam. Sab saum toj tuaj yeem muaj micro-arc ntawm 20mm ~ 30mm. Lub flatness ntawm sab saum toj cib phaj, qhov luaj li cas ntawm seam ntawm lub cib daim hlau, thiab lub sab saum toj qhov siab yuav tsum tau nruj me ntsis guaranteed. Lub seam nruab nrab ntawm lub cib daim hlau yuav tsum tau sau nrog high-purity high-aluminium wool, uas muaj peev xwm xyuas kom meej lub free expansion thiab contraction ntawm txhua lub qab nthab phaj thiab qab nthab cib, thiab kuj zam lub taub hau hluav taws los ntawm strung ua ke thaum lub sij hawm ci ci. Nyob rau tib lub sijhawm, nws tseem yuav tsum tau ua kom ntseeg tau tias thermal expansion ntawm lub qab nthab cib nyob rau hauv high-temperature cheeb tsam muaj txaus qhov chaw kom tsis txhob puas lub qab nthab qauv.
Cov txheej txheem kev ntsuas qhov yuav tsum tau ua rau qab nthab refractory cib: Cov ntsiab lus txhuas ntawm qab nthab cib feem ntau xaiv li 42% h; N-: 1 qib, thiab refractoriness yog 1760 degree. Qhov zoo ntawm qhov chaw tiaj tiaj yog qhov tso zis loj, ua haujlwm yooj yim, me me preheating cheeb tsam roj stratification, thiab cov qauv ruaj khov. Tam sim no nws tau dhau los ua cov khoom lag luam hauv kev lag luam. Flat-top tunnel kilns muaj cov kev cai nruj dua rau cov kiln ru tsev refractories cib. Qhov zoo ntawm lub qhov cub yog nyob ntawm cov khoom siv refractory thiab kev tsim kho raug. Kev xaiv ntawm refractories bricks plays lub luag hauj lwm txiav txim siab nyob rau hauv kev tsim kho zoo ntawm cib kilns, thiab txhim khu kev qha kilns yog lub guarantee ntawm high-zoo khoom tiav. Yog li ntawd, kev xaiv cov khoom siv hluav taws xob zoo refractory cib yog qhov tsim nyog ntawm kev ua kom lub neej ntawm cov kiln thiab cov xwm txheej tsim nyog los xyuas kom meej cov khoom qub ntawm tag nrho cov kab ntau lawm.
