Qhov kev txhim kho zoo ntawm cov alumina bricks yog tsis muaj dab tsi ntau tshaj li kev ua haujlwm siab thiab kub sintering. Txawm li cas los xij, nyob rau hauv cov txheej txheem ntau lawm, peb yuav tsum pib los ntawm qhov chaw thiaj li ua kom zoo dua qhov ruaj khov ntawm cov khoom.
High-alumina bricks tau muab faib ua ib, ob thiab peb qib, thiab qhov zoo ntawm cov cib yog txiav txim siab los ntawm kev ntsuas tshuaj lom neeg thiab lub cev. Tsuas yog thawj qib siab alumina bricks tam sim no siv nyob rau hauv kev ua lag luam, lawv tau pib ua nrog me me ntawm cov khib nyiab cib thiab cov ntaub ntawv raw. Txawm li cas los xij, nws yuav tsum pib nrog cov khoom siv raw matrix.
Hauv kev tsim khoom, kev xaiv cov khoom siv thiab cov khoom xyaw tseem ceeb heev. Kev xaiv cov khoom siv raw yog qhov txuas tseem ceeb. Cov impurities yuav tsum raug xaiv kom tsis txhob molten qhov thiab cov pob dub nyob rau hauv refractory cib. Tom ntej no yog tsim ntawm high-alumina cib. Feem ntau, 90 feem pua ntawm high-alumina bricks yog nias-tsim, thiab tsuas yog ib tug me me ntawm bricks rau tshwj xeeb siv qhov chaw yog manually los yog hydraulically tsim.
Tus nqi ntawm cov dej ntxiv thaum lub sij hawm sib xyaw ntawm lub tshuab compression molding yog tsawg dua li ntawm phau ntawv qhia dej ntxiv. Feem ntau, cov khoom siv raw nrog qhov sib piv zoo yog thawj zaug qhuav sib xyaw, thiab tom qab ntawd dej ntxiv. Cov ntaub ntawv raw ntawm lub tshuab compression molding yog ntxiv nrog 6-8 feem pua dej. Cov dej ntxiv rau molding yog 9-10 feem pua . Cov ntaub ntawv raw rau phau ntawv lossis tshuab compression molding yuav tsum tau nplawm tsis pub tsawg tshaj 8 feeb. Nyob rau hauv txoj cai, nws yog qhuav blended rau 2 feeb, thiab stirred li 10 feeb tom qab ntxiv dej.
Thaum lub sij hawm molding txheej txheem, nws yog ib qho tsim nyog yuav tsum ua kom pom cov khoom ua ntej thiab tom qab ntawd tso tawm cov roj ntawm cov khoom, kom tsis muaj delamination tshwm sim thiab cov compactness muaj zog dua. Yog tias nws yog ib lub cib ua los ntawm tes, koj yuav tsum ntaus ntau ntsug rauj thiab nias rau ntawm ob sab. Tag nrho cov pa tawm hauv cov khoom siv raw. Yog tias cov roj tsis tau tso tawm tag nrho, spallation yuav tshwm sim, uas yuav cuam tshuam rau qhov zoo.
Tom ntej no yog cov khoom sintered. Hauv cov txheej txheem sintering, lub kiln yuav tsum ua tib zoo ua ntej. Lub semi-tiav billets rau lub kiln yuav tsum tau muab ntsia zoo nyob rau hauv lub kiln thiab ib tug tsim nyog qhov hluav taws kub channel yuav muab tso rau ib sab kom tag nrho sinter thiab hlawv tusyees kom cov khoom muaj zog. 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 cov khoom raw matrix, thiab sintering yuav tsum tau nqa tawm nyob rau hauv ib tug oxidizing cua. Cov cua uas txo qis tsis tuaj yeem sintered. Cov xim ntawm lub siab alumina cib sintered nyob rau hauv qhov txo qhov cua yog tsaus, liab thiab dawb. txawv.
Yog hais tias nws yog sinter thawj chav kawm high-alumina bricks, vim hais tias cov particle tis thiab matrix yog zoo, high-temperature sintering yog tsim nyog, thiab lub qhov cub tawm ceev yuav ntev dua lub thib ob los yog thib peb-class high-alumina bricks. Lub sij hawm tawm hauv lub kiln kuj yog ib qho cuab yeej technology uas yuav tsum tau ua tiav hauv cov txheej txheem sintering. Nws tsis tuaj yeem hlawv tag nrho cov khoom hauv 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 lub sab sauv thiab qis lub laub. Tau kawg, lub kiln kuj tuaj yeem ntim tau ntom ntom thiab cov txheej txheem sintering tuaj yeem hloov kho.
Nyob rau hauv luv luv, los txhim kho qhov zoo ntawm siab alumina cib, nws yog ib qhov tsim nyog yuav tau pib nrog cov ntaub ntawv raw thiab mus los ntawm ib tug series ntawm kev ua hauj lwm zoo xws li kev sib tov, sib sau thiab firing los xyuas kom meej ntau yam kev taw qhia ntawm siab alumina cib.
