Magnesia bricks nthuav tawm cov khoom sib txawv ntawm kev yaig tsis kam, feem ntau nyob ntawm lawv cov tshuaj muaj pes tsawg leeg thiab microstructure. Cov hauv qab no yog kev sib piv ntawm kev yaig tsis kam ntawm ntau magnesium raws li bricks:
1. Magnesia chrome cib
Magnesia chromium bricks yog tsim los ntawm sintering sib tov ntawm magnesia xuab zeb thiab chromite, thiab muaj siab refractoriness thiab muaj zog tiv thaiv alkaline slag yaig. Nws muaj kev ruaj ntseg zoo thiab tsis tshua muaj porosity ntawm qhov kub thiab txias, yog li nws muaj kev tiv thaiv zoo rau slag yaig. Txawm li cas los xij, vim muaj cov tshuaj lom ntawm hexavalent chromium, tus naj npawb ntawm cov teb chaws tsim thiab siv magnesia chrome bricks tau maj mam txo.
2. Magnesium aluminium spinel cib
Magnesium aluminium spinel bricks muaj qhov zoo seismic thiab txo qhov ua haujlwm, tab sis ua haujlwm tsis zoo ntawm cov hluav taws kub. Hom cib no muaj zog tiv thaiv alkali yaig thaum siv nyob rau hauv ib qho chaw alkaline. Nws thermal conductivity yog tsawg, thermal expansion coefficient yog me me, lub zog yog siab, thiab hardness yog loj, yog li nws kuj muaj kev ua tau zoo nyob rau hauv corrosion kuj.
3. Magnesium calcium cib
Magnesia calcium cib yog tsim los ntawm magnesia xuab zeb thiab calcium xuab zeb, thiab muaj kev tiv thaiv zoo rau alkaline slag yaig. Kev tshawb fawb tau pom tias rau CaO-SiO2 slag, slag corrosion kuj ntawm cib nce nrog nce CaO cov ntsiab lus hauv cov cib; Rau CaO-Al2O3 slag, qhov xwm txheej yog qhov txawv. Txawm hais tias hom slag, qhov tob tob ntawm cov slag txo qis nrog qhov nce ntawm CaO cov ntsiab lus hauv cib.
4. Magnesium insulated lub teeb yuag refractory cib
Magnesium insulated lub teeb yuag refractory bricks muaj cov yam ntxwv ntawm qhov kub thiab txias tsis kam, siab zog, thiab tseem ceeb zog txuag cov nyhuv. Nws tuaj yeem siv los tsim cov txheej txheem rwb thaiv tsev thiab thaj chaw uas tsis muaj zog yaig thiab cuam tshuam los ntawm cov ntaub ntawv kub kub. Thaum nyob rau hauv kev sib cuag nrog cov nplaim taws, qhov kub ntawm qhov kub ntawm alumina insulated refractory bricks yuav tsum tsis pub tshaj 1350 degree.
Cov ntsiab lus
Hauv cov ntsiab lus, ntau hom magnesia bricks muaj lawv tus kheej qhov zoo thiab qhov tsis zoo ntawm kev yaig kuj. Txawm hais tias magnesia chrome bricks muaj zog corrosion kuj, lawv siv tsuas yog vim muaj teeb meem ib puag ncig. Magnesium aluminium spinel bricks thiab magnesium calcium bricks pom zoo corrosion kuj nyob rau hauv tej yam kev mob, thaum magnesium raws li lub teeb yuag refractory bricks yog haum rau rwb thaiv tsev txheej nyob rau hauv high-temperature ib puag ncig. Thaum xaiv cov pob zeb refractory tshwj xeeb, kev txiav txim siab yuav tsum tau muab raws li kev siv tiag tiag thiab kev xav tau ib puag ncig.
