Hauv kev ua lag luam refractory, cov nqi tswj xyuas tuaj yeem cuam tshuam kev ua haujlwm tau zoo thiab tag nrho cov peev txheej. Ib txoj hauv kev kom txo cov nqi no yog los ntawm kev siv siab - zooMagnesite hmoovHauv kev tsim khoom thiab tu cov tshuab refractory. Magnesia hmoov, tseem hu ua tuag hlawv cov magnesite lossis magnesia (mgo), muaj ob peb qhov zoo uas pab txhawb kev saib xyuas qis dua thiab kev pabcuam kev ncua ntawm kev ua haujlwm refractory.
1. Nkag siab txog magnesia
Magnesia hmoov yog cov khoom siv tseem ceeb hauv kev tsim cov khoom lag luam refractory. Nws yog tus cwj pwm los ntawm nws cov siab magnesium oxide (Mgo) cov ntsiab lus, uas ib yam nkaus li tau dhau 90%. Qhov kev ua siab loj no muab cov khoom siv hluav taws xob zoo dua thiab tshuaj lom neeg, ua rau nws zoo tagnrho rau kev siv high {} kev siv kub xws li cov khoom siv kub, thiab cov iav ntau lawm, thiab ceramics.
2. Kev ua kom tiav siab thiab thermal stability
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm kev siv cov hmoov magnesite yog nws qhov kev ua haujlwm siab dua. Magnes cov xuab zeb muaj qhov tseem ceeb yaj, uas tso cai rau cov ntaub ntawv refractory los tiv thaiv huab tsis muaj kev txwv lossis tsis ua haujlwm. Qhov hluav taws xob hluav taws xob no txo qhov xav tau kev hloov kho nquag thiab kho tau ntau zaus, yog li cov nqi kho me me.
3. Tshuaj Lom Zem thiab Corrosion Kuj
Magnesia hmoov yog tshuaj inert thiab muaj kev tiv taus corrosion los ntawm slag thiab molten cov hlau. Cov cuab yeej no yog qhov tseem ceeb nyob rau ib puag ncig uas cov khoom siv regractory raug rau kev siv tshuaj ua tau zoo thiab muaj cua sov. Los ntawm kev siv cov magnesage, kho kom tsis txhob muaj kev ncaj ncees rau lub sijhawm ntev dua, txo qhov ntau ntawm kev saib xyuas thiab kho mus.
4. Txhim Kho Thermal Condivity
Magnesite hmoov muaj cov thermal zoo heev thermal, uas pab ua kom muaj kev sib tw kub nyob rau hauv refractory. Qhov kev sib txuam no txo cov cua sov thiab tiv thaiv kev tsim cov kub me, uas yog cov ua rau refactory tsis ua haujlwm. Los ntawm kev txo cov xuab zeb thermal, cov xuab zeb magnesite, magesite xuab zeb ua rau lub neej pabcuam txuas ntxiv, yog li txo cov nqi txij nkawm.
5. Txhim Kho Cov Neeg Kho Tshuab Zog
Refractory cov khoom ua nrog cov ntawv pov thawj siab ntawm cov tshuab muaj zog thiab tiv thaiv kom hnav thiab kev yaig. Lub zog no ua kom ntseeg tau tias lub suab refractory tseem muaj lub suab zoo txawm tias muaj kev ua haujlwm hnyav thiab ua haujlwm hnyav. Lub durability ntawm magnesite hmoov-} Raws cov ntaub ntawv refractory txo tau ntau zaus thiab hloov tus nqi kev txuag nyiaj tau dhau sijhawm.
6. Nqi -}} daws teeb meem zoo
Using magnesia sand in refractory systems not only improves performance but also offers cost-effective solutions. Siab -} price magnesia yog dav muaj thiab sib tw luv, ua rau nws xaiv kev lag luam kom txo tus nqi kho. Ib qho ntxiv, cov kev pabcuam txuas ntxiv lub neej ntawm cov ntaub ntawv refractory txhais ua cov khoom dua thiab cov nqi zog tau cuam tshuam nrog kev saib xyuas thiab kho vaj tse.
Kev siv cov hmoov magnesite hauv cov tshuab refractory muaj ntau cov txiaj ntsig uas ua rau cov nqi txij nkawm. Nws qhov kev ua haujlwm siab dua, kev txhim kho thermal, thiab txhim kho kev xaiv hluav taws xob ua rau nws muaj kev xaiv zoo tshaj plaws rau kev siv kub. Los ntawm kev nqis peev hauv high- zoo magnesite xuab zeb, cov tuam txhab tuaj yeem txuas kev ua haujlwm zoo, thiab ua tiav cov nqi ua haujlwm.
