Hauv cov lag luam kub siab xws li kev ua hlau, kev tsim hluav taws xob arc furnace (EAF), kev ua kom huv, thiab kev smelting hlau uas tsis yog ferrous, cov khoom siv refractory uas muag hauv khw feem ntau ua tsis tau raws li cov xwm txheej ua haujlwm tshwj xeeb.Cov cib magnesia carbontej zaum yuav tsis muaj kev ua tau zoo raws li lub hom phiaj, ua rau muaj kev puas tsuaj ntawm cov ntaub thaiv ntau zaus, lub sijhawm tsis ua haujlwm ntev, cov nqi kho kom zoo dua, thiab kev ua haujlwm tsis zoo. Cov cib magnesia carbon (MgO-C) uas ua raws li kev cai daws cov teeb meem no los ntawm kev xa cov kev daws teeb meem refractory uas tsim los kom phim koj lub cub tawg tsim, qhov kub ua haujlwm, cov khoom sib xyaw slag, cov voj voog thermal shock, thiab qhov hnyav hnav.
Cov cib magnesia carbon yog cov khoom siv refractories zoo tshaj plaws uas sib xyaw ua ke cov magnesia fused lossis sintered (MgO) uas muaj cov graphite flake ntuj, ntxiv dag zog rau cov tshuaj antioxidants tshwj xeeb (aluminium, silicon, lossis boron carbide hmoov) thiab cov khoom siv khi ua haujlwm siab. Qhov kev sib xyaw ua ke no muab kev tiv thaiv zoo rau kev puas tsuaj ntawm cov slag yooj yim, kev poob siab thermal, kev hloov pauv kub siab, thiab oxidation - cov yam ntxwv tseem ceeb rau kev muaj sia nyob hauv cov chaw ua haujlwm hnyav tshaj plaws. Kev kho kom haum rau qhov kev ua tau zoo no ua rau muaj kev ua tau zoo no ib kauj ruam ntxiv, kho txhua qhov sib txawv kom haum rau koj cov kev xav tau ua haujlwm tshwj xeeb, es tsis txhob yuam koj cov txheej txheem kom hloov kho rau ib qho khoom loj-haum-txhua yam.
Cov Kev Xaiv Kho Kom Haum Rau Kev Ua Haujlwm Zoo Tshaj Plaws
Peb cov txheej txheem tsim cov cib magnesia carbon pib nrog kev soj ntsuam ntxaws ntxaws ntawm qhov chaw lossis deb ntawm koj cov khoom siv thiab kev ua haujlwm. Peb kho txhua qhov tseem ceeb kom zoo dua qub kom ruaj khov, siv tau ntev, thiab siv nyiaj tsawg: cov pa roj carbon hloov kho tau (qib carbon qis, tus qauv, lossis qib carbon qis heev) rau kev tswj hwm oxidation thiab kev sib raug zoo ntawm qib hlau; kev kho qhov ceev thiab porosity kom tiv taus kev nkag mus rau hauv slag thiab kev hnav khoom siv; cov duab, qhov loj me, thiab kev tsim qauv sib txuas rau qhov haum zoo meej rau lub qhov cub hluav taws xob, tshem tawm cov qhov sib txawv thiab cov ntsiab lus tsis muaj zog; cov txheej txheem antioxidant tshwj xeeb los txuas lub neej ua haujlwm hauv cov chaw muaj pa oxygen ntau; thiab kev xaiv cov binder (resin lossis pitch-bonded) rau kev txhim kho thermal stability thiab kev ua haujlwm zoo.
Cov kev hloov kho tshwj xeeb no muab cov txiaj ntsig lag luam uas ntsuas tau. Cov cib MgO-C tshwj xeeb ua rau lub neej ua haujlwm ntawm lub cub tawg ntev dua, txo qhov zaus ntawm kev rov ua dua tshiab thiab txiav lub sijhawm tsis ua haujlwm txog li 50% piv rau cov cib txheem. Kev tiv thaiv thermal shock zoo tshaj plaws txo qhov spalling thiab tawg, thaum tiv thaiv slag tsom mus rau kev tiv thaiv kev puas tsuaj ua ntej lub sijhawm, txo cov nqi hloov pauv refractory mus sij hawm ntev. Kev ntsuas qhov loj me tshwj xeeb kuj ua rau kev teeb tsa sai dua, txo lub sijhawm ua haujlwm thiab kev ncua sijhawm ntau lawm - tseem ceeb rau kev ua tiav cov sijhawm tsim khoom nruj.
Cov Ntawv Thov Zoo Tshaj Plaws rau Kev Cai Magnesia Carbon Bricks
Cov cib magnesia carbon uas ua raws li tus neeg xav tau yog tsim los rau cov cheeb tsam uas muaj kev hnav khaub ncaws hnyav thiab kub heev uas cov khoom siv refractories txheem tsis txaus. Cov ntawv thov tseem ceeb suav nrog EAF lub cub tawg phab ntsa thiab ru tsev, cov kab ladle slag thiab cov ntaub ua haujlwm, cov ntaub hloov pauv, cov khoom siv refining cub tawg, thiab cov khoom siv smelting hlau uas tsis yog ferrous. Peb kuj tsim cov qauv tshwj xeeb rau cov xwm txheej ua haujlwm tshwj xeeb, xws li cov cub tawg kev lag luam kub siab, cov cub tawg pov tseg, thiab lwm yam khoom siv thermal hnyav uas xav tau kev tiv thaiv refractory tshwj xeeb.
Vim Li Cas Thiaj Koom Tes Nrog Peb Rau Koj Cov Kev Xav Tau MgO-C Cib
Ua ib lub tuam txhab tsim khoom siv hluav taws xob uas ua raws li kev cai, peb muab ntau xyoo ntawm kev txawj ntse hauv kev lag luam, kev tswj xyuas zoo, thiab thev naus laus zis tsim khoom siab heev los xa cov cib magnesia carbon uas txhim khu kev qha thiab ua tau zoo. Peb tsuas yog siv cov khoom siv raw uas huv si, nrog rau kev sib xyaw ua ke thiab kev tsim khoom siab kom ntseeg tau tias muaj qhov sib xws thiab kev sib xws ntawm cov qauv thoob plaws txhua qhov kev txiav txim. Peb pab neeg ua haujlwm ua haujlwm nrog koj txij li kev sab laj thawj zaug mus txog rau qhov xa khoom kawg, muab kev tsim qauv tus kheej, kev kuaj qauv, thiab kev txhawb nqa tom qab muag kom lav qhov sib xws thiab kev ua tau zoo. Peb ua raws li cov qauv hluav taws xob thoob ntiaj teb, kom ntseeg tau tias txhua lub cib ua tau raws li kev nyab xeeb, kev ruaj khov, thiab kev tiv taus cua sov.
Tsis txhob cia cov khoom siv refractory dav dav txwv koj txoj kev ua haujlwm zoo lossis ua rau koj cov nqi kho dua tshiab ntau dua. Nqis peev rau hauv cov cib magnesia carbon uas tsim tshwj xeeb rau koj cov txheej txheem tshwj xeeb, thiab qhib lub neej cub kom ntev dua, txo lub sijhawm tsis ua haujlwm, txo cov nqi, thiab ruaj khov dua. Txawm hais tias koj xav tau cov cib me me uas zoo li cov duab tshwj xeeb lossis cov tshuaj pleev xim rau hauv lub cub kom tiav, peb xa cov khoom siv refractory uas ua haujlwm tau zoo hauv qab qhov kub thiab siab heev.
Tiv tauj peb hnub no los tham txog koj cov kev xav tau ntawm cov cib magnesia carbon, thov kev sab laj dawb, lossis tau txais kev hais nqe raws li koj xav tau. Cia peb cov kws tshaj lij refractory tsim ib qho kev daws teeb meem uas tsa koj cov haujlwm kub siab mus rau qib tshiab ntawm kev ntseeg siab thiab kev ua lag luam.
