YUAV UA LI CAS YUAV TSUM PAUB TXOG QHOV CHAW UA HAUJ LWM NTAWM HIGH ALUMINA BRICKS

Paub txog qhov zoo thiab qib siab ntawm alumina cib tuaj yeem txheeb xyuas los ntawm peb yam: zoo li, lub cev ntom ntom, thiab kev sim kuaj.
Ua ntej, txheeb xyuas los ntawm cov xim xim: yog xim daj, nws yog qib thib peb siab alumina cib, yog tias xim daj-dawb, nws ua pov thawj tias yog qib thib ob siab alumina cib, yog tias nws yog xim dawb, tau ua pov thawj tias yog thawj chav kawm siab alumina cib. Yog hais tias cov tsos ntawm peb cov xim no tsis du los yog tsis muaj lub sij hawm siv lead ua, nws txhais tau hais tias sintering kub yog tsawg thiab lub zog tsis zoo thaum siv.
Tsis tas li ntawd, nws nyob ntawm seb puas muaj cov pob dub ntawm qhov chaw lossis thaj chaw loj ntawm cov khoom molten. Yog tias muaj cov pob dub, nws yog vim cov ntsiab lus hlau ntawm cov khoom siv raw yog siab dhau, thiab cov qhov tsua karst yuav tshwm sim thaum siv, uas yuav cuam tshuam rau lub neej kev pabcuam. Nws kuj nyob ntawm seb qhov chaw tiaj tus. Yog tias qhov chaw tsis tiaj tus, nws yog vim tias ob txhais ceg raug kub hnyiab thaum sintering, thiab muaj cov cib loj nias rau ntawm nws, thiab qhov chaw tsis sib xws. Qhov no tseem yuav cuam tshuam rau txheej staggered thaum lub sij hawm masonry thiab tseem yuav cuam tshuam rau lub neej kev pab cuam tom qab siv.
Cov kauj ruam tom ntej yog saib qhov loj. Qhov loj yog ntsuas nrog tus pas ntsuas. Yog hais tias qhov ntev, dav thiab thickness ntawm lub siab alumina cib yog ntau tshaj 2 hli, nws txhais tau hais tias qhov loj ntawm pwm yog loj. Nws kuj yuav yog vim li cas rau cov khoom siv raw. Tus pas ntsuas yuav nce ntxiv tom qab sintering. Yog tias qhov loj me yog sib npaug ntau dua 3 hli saum toj no. High alumina cib ntawm qhov loj me no tsis tuaj yeem siv.
Qhov zoo kuj tuaj yeem pom los ntawm cov khoom loj. Txoj kev xeem yog siv lub ntsuas hluav taws xob los ntsuas ib qho cib, tom qab ntawd ntsuas qhov ntev, qhov dav, qhov siab lossis qhov loj ntawm lub taub hau, thiab tom qab ntawd xam qhov ntim. Faib qhov hnyav los ntawm qhov ntim kom tau qhov siab. Yog tias qhov tshwj xeeb lub ntiajteb txawj nqus ntawm aluminium cib qis dua 2.3, nws tau ua pov thawj tias yog qib peb qib siab alumina cib. Yog tias qhov ntom ntom ntau dua 2.3, nws yog qib thib ob qib high-alumina cib. Yog hais tias qhov ntau ntom yog siab dua 2.45, nws yog thawj qib high-alumina cib.
Cov ntsiab lus ntawm aluminium refractory cib, yog tias cov ntsiab lus txhuas yog 55 feem pua, nws yog qib peb qib high-alumina cib, yog tias nws yog 65 feem pua, nws yog qib thib ob qib high-alumina cib, yog tias nws yog 75 feem pua, nws yog thawj qib high-alumina cib, tab sis cov ntsiab lus aluminium yog Nws tsuas yog paub los ntawm kev kuaj tshuaj. Intuitively tsis pom.
Tsis tas li ntawd, lub zog, thermal shock, thiab reburning kab hloov ntawm refractory bricks yog tag nrho cov paub los ntawm lub cev chemistry, uas yog pom tsis tau ntawm qhov muag liab qab.
Lub load softening kub ntawm refractory bricks kuj yog cov khoom tseem ceeb tshaj plaws nyob rau hauv txoj kev siv. Muaj ob txoj hauv kev los txheeb xyuas qhov no. Ib qho yog saib qhov kub ntawm sintering. Yog hais tias lub sintering kub yog 1380, ces lub load yog hais txog 1400. Yog hais tias lub sintering kub yog 1450, ces lub load kub yog nyob ib ncig ntawm 1480. Txawm li cas los, yog hais tias lub load softening kub yuav tsum tau ntau tshaj, nws yuav tsum tau kuaj.
Nyob rau hauv ib txwm muaj, qhov zoo ntawm alumina bricks yog txiav txim los ntawm peb txoj kev intuitive: xim, loj shrinkage, thiab lub cev ceev. Tau kawg, yog tias cov neeg siv thov lwm qhov ntsuas, lawv yuav tsum tau kuaj xyuas ua ntej lawv tuaj yeem paub.
Raws li lub teb chaws tus qauv, nws muab faib ua ib, ob, thiab peb theem, uas yog muab faib ua 55 feem pua, 65 feem pua, thiab 75 feem pua ​​ntawm txhuas cov ntsiab lus.
Tam sim no nyob rau hauv kev ua lag luam, vim hais tias ntawm qhov sib txawv ntawm lub cub tawg hom thiab kub, muaj ntau ntau yam khoom raws li qhov sib txawv rauv kub, 55 feem pua, 65 feem pua, 68 feem pua, 70 feem pua, 72 feem pua, 75 feem pua, qhov diversification ntawm 80 feem pua. aluminium cov ntsiab lus yog vim qhov tseeb tias tus nqi kuj tau muab faib ua ntau theem.
Nyob rau hauv txoj kev no, ntau thiab ntau cov khoom yog haum rau kub thiab pheej yig. Qhov no kuj yog vim qhov tseeb. Kev sib kis ntawm xyoo 2020 thiab dej nyab xyoo 2021 tau ua rau ntau lub tuam txhab raug kev txom nyem hnyav, thiab cov nqi sib txawv ntawm peb hom cib ntawm qib thawj, qib thib ob thiab qib thib peb txawv heev. Qee lub cub tawg raug xaiv rau qhov kub nruab nrab. Cov khoom siv kub yog siv los ua cov ntaub hauv cov ntaub, yog li txawm tias nws siv, tus nqi yuav raug txo. Qhov no kuj yog qhov xwm txheej uas high-alumina bricks tau siv ntau qib vim qhov xwm txheej tiag tiag.
Ntau tshaj li kaum xyoo dhau los, 48 ​​feem pua ​​​​cov ntsiab lus txhuas tuaj yeem hu ua qib peb qib high-alumina cib. Hauv kev tsim khoom tam sim no, cov ntsiab lus txhuas ntawm cov av nplaum yog li 58 feem pua. Yog li ntawd, 48 feem pua ​​​​cov ntsiab lus ntawm txhuas tsuas yog av nplaum cib. Yeej, yog tias cov ntsiab lus txhuas tsawg dua 65 feem pua ​​​​thiab cov ntsiab lus txhuas nyob rau hauv thaj tsam ntawm 60 feem pua, nws yog ntuj thib peb qib high-alumina cib uas tau pom zoo pom zoo. Cov ntsiab lus ntawm aluminium tau nce ntau heev.
Txawm li cas los xij, txawm li cas los xij cov ntsiab lus zoo li cas yog, qhov ntom ntom thiab thauj khoom softity thiab thauj softening kub yog tus yuam sij los tswj cov khoom lag luam zoo. Yog tias qhov ntom ntom tsis ncav cuag, nws ua pov thawj tias qhov zoo ntawm cov khoom tsis zoo, thiab cov khoom siv softening kub yog qhov txwv uas tuaj yeem ua pov thawj zoo tshaj plaws ntawm cov cib, vim tias qhov load ntawm softening kub yog qhov nyuaj tshaj plaws kom ua tiav. . Qhov laj thawj yog vim li cas cov khoom siv raw yog cov khoom siv. Tib neeg tswj tsis tau lawv yog tias lawv raug tshem tawm hauv av lossis mines.
Thaum yuav cov khoom siv raw, tus nqi txiav txim siab raws li cov ntsiab lus ntawm txhuas thiab qhov ntom ntom ntawm cov khoom siv raw. Thaum lub softening kub nyob rau hauv load tsis tuaj yeem ncav cuag, ib feem ntawm cov khoom siv sab nraud yuav tsum tau ntxiv kom ua tiav nws. Yog li ntawd, qhov siab dua qhov softening kub nyob rau hauv load, qhov kev ua tau zoo dua. Qhov no kuj yog vim li cas rau kev sib txawv ntawm nws cov ntsiab lus txhuas.
