Yuav ua li cas los txhim kho qhov zoo ntawm high aluminium bricks thaum lub sij hawm tsim khoom?
Qhov kev txhim kho zoo ntawm cov aluminium bricks yog tsis muaj dab tsi ntau tshaj li high-pressure molding thiab high-temperature sintering. Txawm li cas los xij, hauv cov txheej txheem tsim khoom, peb yuav tsum pib los ntawm qhov chaw kom zoo dua kom ruaj khov ntawm cov khoom.
1. High alumina bricks muab faib ua thawj, thib ob thiab thib peb theem
high aluminium bricks muab faib ua qib ib, ob thiab peb. Kev faib tawm zoo ntawm cib yog txiav txim siab raws li kev ntsuas tshuaj lom neeg thiab lub cev. Covsiab alumina refractory cibtam sim no siv nyob rau hauv kev ua lag luam, tshwj tsis yog rau cov thawj-qib sawv daws yuav, yog tsim los ntawm ib tug me me ntawm cov khib nyiab bricks thiab raw cov ntaub ntawv. Txawm hais tias qhov piv yog dab tsi, koj yuav tsum pib nrog cov khoom siv raw matrix.
Hauv cov txheej txheem tsim khoom, xaiv cov khoom siv thiab cov khoom xyaw tseem ceeb heev. Kev xaiv cov khoom siv raw yog thawj kauj ruam. Cov impurities yuav tsum tau txheeb xyuas kom tsis txhob yaj qhov thiab cov pob dub hauv cov cib refractory. Cov kauj ruam tom ntej yog kev tsim cov alumina cib siab. Feem ntau, 90% ntawm siab alumina refractory cib yog tshuab tsim. Tsuas yog ib qho me me ntawm cov cib rau kev siv tshwj xeeb yog tsim los ntawm tes lossis hydraulically.
2. High alumina cib ua txheej txheem
Tus nqi ntawm cov dej ntxiv thaum sib tov lub tshuab-tsim siab aluminium bricks yog tsawg dua li ntawm phau ntawv sib xyaw. Feem ntau, cov khoom siv raw nrog cov proportions zoo yog qhuav-sib xyaw ua ntej, thiab tom qab ntawd dej ntxiv. Cov dej ntxiv rau lub tshuab tsim cov ntaub ntawv raw yog 6-8 %, tus nqi ntawm cov dej ntxiv rau phau ntawv molding yog 9-10%. Txawm hais tias nws yog tes-tsim los yog tshuab-nias, cov ntaub ntawv raw ntawm high-alumina cib yuav tsum tau nplawm tsis pub tsawg tshaj 8 feeb. Nyob rau hauv txoj cai, nws yog qhuav sib tov rau 2 feeb, thiab ces do li 10 feeb tom qab ntxiv dej.
Thaum lub sij hawm molding txheej txheem ntawm siab aluminium bricks, lawv yuav tsum tau lightened ua ntej thiab ces hnyav kom tso pa tawm ntawm cov khoom, kom lub siab alumina bricks yuav tsis tawg thiab ua denser. Yog tias nws yog ib lub cib xuas tes ua, koj yuav tsum siv cov hammers ntsug ntau dua thiab nias ob sab. Cia cov huab cua nyob rau hauv cov ntaub ntawv raw kom tag nrho. Yog tias cov roj tsis tau tso tawm tag nrho, spalling yuav tshwm sim, cuam tshuam rau qhov zoo ntawm high-alumina cib.
3. Cov khoom raug rho tawm haujlwm
Cov kauj ruam tom ntej yog ci cov khoom. Thaum lub sij hawm sintering txheej txheem, yuav tsum tau ceev faj ua hauj lwm pib los ntawm lub kiln installation. Cov khoom lag luam semi-tiav yuav tsum tau muab tso rau hauv qhov cub kom zoo thiab tawm hauv txoj hauv kev tsim hluav taws xob, kom lub siab aluminium cib tuaj yeem ua tiav thiab sib npaug. Xyuas kom lub zog ntawm cov khoom. Thaum lub sij hawm sintering txheej txheem ntawm cov khoom uas tau dhau los ntawm lub tshuab ziab khaub ncaws, sintering kub yuav tsum tau txiav txim siab raws li qib ntawm raw khoom matrix, thiab sintering yuav tsum tau nqa tawm nyob rau hauv ib tug oxidizing cua thiab tsis nyob rau hauv ib tug txo qhov chaw. Cov xim ntawm high alumina cib sintered nyob rau hauv ib tug txo qhov cua yuav tsaus, liab thiab dawb. Tsis zoo ib yam.
4. Kho qhov sib faib ntawm qhov hluav taws kub hauv qhov cub thaum lub sij hawm sintering
Yog hais tias thawj-theem high-temperature bricks yog sintered, vim hais tias cov particle tis thiab matrix yog zoo, lawv yuav tsum tau sintered nyob rau hauv high kub, thiab qhov tso tawm ceev ntawm lub kiln yuav ntev dua li ntawm theem ob los yog thib peb-theem. siab aluminium bricks. Lub sij hawm tawm ntawm lub qhov cub kuj yog ib qho cuab yeej uas yuav tsum tau ua kom zoo nyob rau hauv cov txheej txheem sintering. Tag nrho cov khoom tsis tuaj yeem raug rho tawm haujlwm tib lub sijhawm sintering. Lub sijhawm sintering thiab kiln tawm yog txiav txim siab raws li qib ntawm cov khoom siv raw.
Thaum lub sij hawm sintering txheej txheem, nws yog ib qhov tsim nyog los kho qhov kev faib tawm ntawm qhov hluav taws kub qhov cub thiab kho qhov kub ntawm qhov sib txawv ntawm qhov nruab nrab thiab qis ntawm lub tsheb kiln. Tau kawg, lub kiln kuj tuaj yeem ntsia tau ntom ntom rau saum toj thiab sparsely hauv qab, uas kuj yog ib txoj hauv kev los kho cov sintering.
Nyob rau hauv luv luv, los txhim kho qhov zoo ntawm high aluminium bricks, peb yuav tsum pib nrog raw cov ntaub ntawv, thiab ces mus los ntawm ib tug series ntawm meej kev khiav hauj lwm ntawm kev sib tov, shaping, thiab firing los xyuas kom meej ntau yam qhia ntawm high alumina cib.
