Hauv kev lag luam kub siab, kev ua tau zoo ntawm cov ntaub ntawv hauv qhov cub tawg cuam tshuam ncaj qha rau kev ua haujlwm zoo thiab cov khoom zoo. Ua tus sawv cev ntawm cov ntaub ntawv refractory ua tau zoo, magnesia-alumina spinel cib, nrog lawv cov khoom zoo heev, tau dhau los ua qhov kev xaiv zoo tshaj plaws rau kev lag luam xws li hlau, iav, thiab cement kom tiv taus kev kub siab thiab txuas ntxiv lub neej ntawm cov khoom siv, muab kev txhawb nqa txhim khu kev qha rau kev tsim khoom lag luam kub siab.
Ua Tus Thawj Coj Hauv Kev Lag Luam Nrog Kev Ua Tau Zoo Tshaj Plaws
Cov cib magnesia-alumina spinel yog ua los ntawm magnesia thiab aluminium oxide los ntawm cov txheej txheem tshwj xeeb. Lawv cov qauv siv lead ua tshwj xeeb ua rau lawv muaj txiaj ntsig zoo. Cov cib no ua rau muaj kev tiv taus kub siab heev, muaj peev xwm tiv taus kub txog li 1800 ° C. Txawm tias nyob hauv qhov chaw kub ntev, lawv tseem muaj cov khoom siv lub cev thiab tshuaj lom neeg ruaj khov, tiv thaiv kev puas tsuaj rau cov ntaub hauv qhov cub los ntawm qhov kub siab.
Kev tiv thaiv kev poob siab ntawm cov cib magnesia-alumina spinel yog ib qho tshwj xeeb ntawm kev ua kom sov thiab txias ntawm cov qhov cub, cov khoom siv refractory ib txwm muaj feem tawg thiab tawg vim muaj kev ntxhov siab ntawm thermal. Txawm li cas los xij, nrog lawv cov coefficient qis ntawm kev nthuav dav thermal thiab kev tawv zoo, cov cib magnesia-alumina spinel tuaj yeem txo cov kev cuam tshuam ntawm kev ntxhov siab ntawm thermal, txo qhov kev pheej hmoo ntawm kev puas tsuaj ntawm thermal, ntev lub neej ua haujlwm, thiab txo qis lub sijhawm tsis ua haujlwm ntawm qhov cub rau kev saib xyuas.
Cov cib Magnesia-alumina spinel kuj ua tau zoo heev hauv kev tiv thaiv kev yaig tshuaj. Lawv muaj kev tiv thaiv zoo rau alkaline thiab acidic slag, nrog rau cov pa roj kub siab, tiv thaiv kev nkag mus ntawm cov tshuaj lom neeg thiab tiv thaiv kev nyab xeeb ntawm cov qauv ntawm lub cub tawg. Txawm hais tias nyob rau hauv ib puag ncig alkaline siab ntawm kev smelting hlau lossis qhov kub siab acidic ntawm kev tsim iav, lawv tuaj yeem ua tiav lawv cov haujlwm tiv thaiv.
Cov Ntawv Thov tob tob thoob plaws ntau yam lag luam
Hauv kev lag luam hlau, cov cib magnesia-alumina spinel siv dav hauv cov chaw tseem ceeb ntawm cov khoom siv hloov pauv, cov tais diav, thiab cov khoom siv tundishes. Thaum lub sijhawm ua cov hlau hloov pauv, lawv tuaj yeem tiv taus qhov khawb thiab kev yaig ntawm cov hlau molten kub thiab slag, ua kom ntseeg tau tias cov ntaub thaiv ntawm cov khoom siv hloov pauv muaj kev ncaj ncees. Thaum siv rau hauv cov tais diav thiab cov khoom siv tundishes, lawv tuaj yeem txo qhov kev sib xyaw ntawm cov hlau molten thiab cov ntaub thaiv, txhim kho qhov huv ntawm cov hlau molten, thiab txhim kho qhov zoo ntawm cov hlau. Tom qab lub tuam txhab hlau loj tau txais cov cib magnesia-alumina spinel, lub neej ua haujlwm ntawm nws cov tais diav tau nce ntxiv los ntawm qhov nruab nrab ntawm 60 qhov kub mus rau 120 qhov kub, txo cov nqi tsim khoom.
Hauv kev lag luam tsim iav, cov cib magnesia-alumina spinel yog cov khoom siv zoo tshaj plaws rau cov khoom tseem ceeb ntawm cov qhov cub iav. Hauv cov chaw kub thiab cov khoom siv rov ua dua tshiab ntawm cov qhov cub iav yaj, lawv tuaj yeem tiv taus kev yaig ntawm cov iav yaj kub thiab cov pa roj kub, tswj kev ruaj khov ntawm lub qhov cub, txo qhov zaus saib xyuas qhov cub, thiab txhim kho kev sib txuas thiab kev ruaj khov ntawm kev tsim iav. Tom qab siv cov cib magnesia-alumina spinel, lub voj voog kho dua tshiab ntawm cov qhov cub iav tuaj yeem ntev dua 2 - 3 xyoos, ua kom zoo dua cov txiaj ntsig kev lag luam ntawm cov lag luam.
Thaum lub sijhawm tsim cov cement, qhov chaw kub siab ntawm lub qhov cub rotary tso cov kev cai nruj rau cov khoom siv refractory. Nrog lawv cov kev tiv taus kub siab, kev tiv taus kev sib txhuam, thiab kev ruaj khov tshuaj lom neeg zoo, magnesia-alumina spinel cib ua lub luag haujlwm tseem ceeb hauv thaj chaw hloov pauv thiab thaj chaw hlawv ntawm lub qhov cub rotary, ua kom lub cev lub qhov cub ua haujlwm ruaj khov hauv qhov kub siab thiab cov xwm txheej siab thiab pab txhawb rau kev tsim cov cement ntau ntxiv thiab txhim kho qhov zoo.
Phau Ntawv Qhia Txog Kev Yuav Khoom
Thaum xaiv cov cib magnesia-alumina spinel, cov ntsiab lus tseem ceeb hauv qab no yuav tsum tau hais txog: Ua ntej, them sai sai rau cov tshuaj lom neeg thiab cov khoom siv hauv cov khoom siv. Cov khoom siv raw magnesia thiab aluminium oxide uas muaj cov khoom siv siab tuaj yeem ua kom cov cib ua haujlwm ruaj khov. Qhov thib ob, tsom mus rau cov ntsuas kev ua haujlwm ntawm cov khoom, xws li qhov ceev ntawm cov khoom, qhov pom tseeb porosity, thiab lub zog sib tsoo txias ntawm chav tsev kub. Cov ntsuas no qhia ncaj qha rau qhov zoo thiab kev ua haujlwm ntev ntawm cov cib. Qhov thib peb, ntsuas cov txheej txheem tsim khoom thiab cov txheej txheem tswj xyuas zoo ntawm cov neeg muab khoom. Xaiv cov neeg muab khoom nrog cov khoom siv tsim khoom siab heev, cov txheej txheem tshuaj xyuas tiav, thiab kev paub txog kev lag luam nplua nuj kom ntseeg tau tias cov khoom zoo. Tsis tas li ntawd, raws li cov xwm txheej ua haujlwm tshwj xeeb, qhov tseeb ntawm qhov ntev thiab kev hloov pauv ntawm cov cib kuj tseem yuav tsum tau txiav txim siab kom ntseeg tau tias kev tsim kho thiab kev teeb tsa du.
Nrog lawv cov kev ua tau zoo tshaj plaws thiab kev siv dav dav, cov cib magnesia-alumina spinel tau dhau los ua cov khoom siv refractory ua tau zoo hauv kev lag luam kub siab. Txawm hais tias nws yog kev txhim kho kev tsim khoom zoo, txo cov nqi, lossis kev ua kom cov khoom zoo, lawv tuaj yeem muab cov kev daws teeb meem txhim khu kev qha rau cov tuam txhab. Tiv tauj peb tam sim no kom tau txais cov ntaub ntawv khoom tshaj lij thiab cov kev pabcuam tshwj xeeb, thiab cia peb tiv thaiv koj cov khoom lag luam kub siab!
