1. Cov Khoom Siv Raw Khoom Zoo
Tshuaj lom neeg tshuaj lom neeg: cov ntsiab lus alumina yuav tsum ua kom tau raws li cov kev cai ntawm cov qib refractory. Feem ntau hais lus, ntau dua cov alumina cov ntsiab lus nyob rau hauv cov khoom siv aluminium high-aluminium, qhov zoo dua cov khoom siv refactory ntawm cov khoom siv refactory. Piv txwv li, rau qee qib high-aluminiumRefractor Cib, cov alumina cov ntsiab lus yuav xav tau txog 70% lossis siab dua. Cov ntsiab lus uas impurity cov ntsiab yuav tsum tau nruj me ntsis tswj vim tias cov impurities yuav txo cov khoom siv kub ntawm cov khoom siv hluav taws xob siab. Piv txwv li, ntau dhau alkali hlau oxides (cov poov tshuaj oxides (sodium oxide) yuav ua rau cov khoom siv tsawg dua, ua rau cov khoom siv refactatures thiab deform negularures. Nws tseem tsim nyog yuav tau them sai sai rau cov ntsiab lus thiab cov feem ntawm lwm qhov tseem ceeb xws li silicon dioxide nyob rau hauv cov ntaub ntawv raw. Qhov uas haum kom zoo tshaj plaws silicon-aluminium piv muaj qhov tseem ceeb ntawm theem muaj pes tsawg leeg thiab ua haujlwm ntawm cov khoom siv.
Qhov loj me me thiab qhov ntsuas me me: qhov me me ntawm cov khoom siv high-aluminium yuav tsum ua kom tau raws li cov khoom lag luam kawg, thiab yuav tsum muaj kev sib tw ua kom zoo thiab ua tiav zoo. Yog hais tias cov lus me me dhau heev, qhov ntom ntawm lub cev ntsuab tom qab molding tej zaum yuav tsis zoo, cuam tshuam rau lub zog thiab kev ua haujlwm tsis huv; Yog hais tias cov lus tau zoo heev, lub cev ntsuab tau muaj huab cua tsis zoo thiab tawg thiab tawg thiab lwm yam tsis xws luag tuaj yeem tshwm sim thaum lub tshuab ziab khaub ncaws. Los ntawm Scientific Partlet Mas, xws li siv cov ntaub ntawv txuas ntxiv, uas pab txhim kho qhov kev ua tau zoo tag nrho ntawm cov khoom ua tiav.
2. Moulding cov txheej txheem yuav tsum tau ua
Binder Xaiv: Xaiv cov phau ntawv uas haum raws li cov hom tshwj xeeb ntawm cov khoom siv hluav taws xob siab; kev siv cov xwm txheej. Cov uas muaj cov av nplaum muaj suav nrog cov av nplaum binders thiab phosphate binders. Cov av nplaum tsis tshua muaj nqi thiab tuaj yeem muab lub cev ntsuab ntsuab thiab ua kom muaj zog, uas yog pab rau moulding; Phosphate Binders tuaj yeem ua rau cov khoom muaj zog muaj zog dua thiab lwm yam khoom, haum rau qee lub sijhawm uas yuav tsum tau ua kom muaj qhov kub siab. Tus nqi ntawm binder ntxiv yuav tsum yog precisely tswj. Yog tias tus nqi ntxiv yog tsawg heev, lub cev ntsuab yuav tsis txaus nyob rau hauv lub zog tom qab molding thiab nws yooj yim kom plam; Yog tias tus nqi ntxiv yog ntau dhau, ntau dhau impurities yuav tau qhia, lossis kev ua tau zoo ntawm cov khoom yuav cuam tshuam. Piv txwv li, qee cov binders decompose nyob rau qhov kub thiab txias los tsim cov roj ntau dhau, ua rau muaj teeb meem xws li xoob cov qauv xoob.
Moulding siab tswj: Txawv cov khoom siv hluav taws xob siab dua tshiab yuav tsum raug rau cov tshuaj molding tsim nyog raws li lawv cov qauv, qhov loj me thiab siv cov cai. Piv txwv li, thaum ua cov cib refractory, haum siab tuaj yeem ua kom zoo dua qub, txhim kho qhov tseeb thiab ua kom pom kev zoo ntawm lub cib. Yog tias lub siab yog tsawg dhau, qhov ceev ntawm qhov dawb paug tsis txaus, thiab cov khoom tiav tau nquag muaj teeb meem zoo xws li kaum poob thiab ntug poob; Thaum yog lub siab siab dhau lawm, cov pwm yuav puas tsuaj, thiab rau qee cov kab kos nrog cov qauv tshwj xeeb lossis cov khoom tawg sab hauv thiab lwm yam tsis xws luag.
3. Cov txheej txheem tua hluav taws yuav tsum muaj
Cov yam ntxwv uas tsim nyog hluav taws kub yuav tsum txiav txim siab raws cov yam ntxwv ntawm high-aluminium refractory cib thiab cov khoom ntsuas kev ua haujlwm ntawm lub hom phiaj refractory. Feem ntau hais lus, raws li kev tua hluav taws kub nce ntxiv, cov khoom tawg hauv cov khoom tawg hauv cov khoom siv hluav taws xob uas muaj zog ntxiv, uas yuav pab txhim kho lub zog thiab kev ua kom zoo dua thiab lwm yam khoom. Txawm li cas los xij, kev kub dhau heev yuav ua rau overburning, thiab tej zaum kuj yuav ua rau tsis xav tau qee qhov kev ntxhov siab, cuam tshuam rau cov khoom lag luam hnyav; Yog tias qhov ntsuas kub tsawg dhau, qhov dawb paug tsis yog stericators txaus, thiab cov ntsuas kev ua tau zoo xws li ntom thiab lub zog tsis tuaj yeem ua tau raws li cov cai.
Tus ntsuas cua sov thiab tuav lub sijhawm thaum lub sij hawm tua hluav taws kuj yuav tsum tau ua nruj ua raws li cov txheej txheem kev ua kom muaj zog thiab muaj kev ruaj khov thiab txhim khu kev qha.
