Cov yam ntxwv ntawm kev ua tau zoo:
Ua ib yam khoom siv refractory ua tau zoo, cov cib corundum muaj cov yam ntxwv zoo heev, thiab ntau hom cib corundum ntxiv txhim kho kev ua tau zoo raws li cov yam ntxwv saum toj no:
1. Kev kub hnyiab siab:Qhov refractoriness tuaj yeem ncav cuag siab dua 1750 ℃, thiab qee cov khoom muaj cov khoom huv si (xws li cov cib corundum dawb) tuaj yeem tiv taus qhov kub siab ntev tshaj 1800 ℃, tswj kev ruaj khov hauv qhov chaw kub siab yam tsis muaj kev hloov pauv lossis kev puas tsuaj.
2. Muaj Zog:Nws muaj lub zog compressive siab hauv chav tsev kub, txog li 340MPa, thiab tuaj yeem dais cov khoom siv kho tshuab ntawm qhov kub siab. Ntawm lawv, cov cib corundum dawb muaj lub zog kho tshuab zoo heev hauv qhov kub siab.
3. Kev Ruaj Ntseg Tshuaj Zoo:Nws muaj zog tiv taus cov kua qaub lossis alkaline slag, hlau, iav yaj, thiab lwm yam, thiab tsis yooj yim rau kev hloov pauv tshuaj lom neeg. Dawb corundum cib muaj qhov ruaj khov tshuaj zoo tshaj plaws vim nws qhov huv siab.
4. Kev Tiv Thaiv Slag Zoo Thiab Kev Tiv Thaiv Kev Yaig:Tshwj xeeb tshaj yog muaj zog heev tiv taus cov kua qaub, nruab nrab thiab qee cov alkaline molten slags. Chrome corundum cib yog qhov tshwj xeeb tshaj yog zoo hauv qhov kev ua tau zoo no, uas tuaj yeem ua kom lub neej ua haujlwm ntev dua.
5. Kev Ruaj Ntseg Zoo ntawm Thermal Shock:Txawm hais tias tsis zoo li qee cov ntaub ntawv uas muaj silicon lossis magnesia, nws tuaj yeem txhim kho tau zoo los ntawm kev ntxiv zircon (xws li zirconia corundum cib) lossis kho qhov sib txawv ntawm cov khoom me me. Zirconia corundum cib muaj kev ruaj khov thermal zoo dua.
Pob zeb corundum-mulliteyog cov khoom siv hluav taws xob zoo tshaj plaws nrog corundum thiab mullite ua cov theem crystalline tseem ceeb. Los ntawm qhov ua haujlwm synergistic ntawm ob theem tseem ceeb, nws koom ua ke qhov kub siab tiv taus thiab corrosion tsis kam ntawm corundum nrog qhov zoo heev thermal shock stability ntawm mullite. Cov khoom no tau lees paub dav hauv kev lag luam kub thoob ntiaj teb xws li metallurgy, iav, petrochemicals, thiab carbon dub ntau lawm, muab cov kev daws teeb meem txhim khu kev qha rau cov khoom tseem ceeb ntawm lub kiln thiab txhim kho cov khoom siv ua haujlwm zoo thiab lub neej ua haujlwm.
Cov Kev Zoo Tseem Ceeb ntawm Kev Ua Haujlwm:
1. Kev tiv thaiv kev poob siab zoo heev:Qhov no yog nws qhov zoo tshaj plaws. Mullite muaj cov coefficient qis ntawm kev nthuav dav thermal, thiab nws cov qauv siv lead ua zoo li koob nqus cov kev ntxhov siab los ntawm kev hloov pauv kub, txo qhov tawg los ntawm kev txias thiab cua sov sai ntawm qhov kub siab. Nws cov kev ua tau zoo tshaj qhov ntawm cov cib corundum ntshiab.
2. Lub zog sib npaug thiab kev tiv thaiv corrosion:Qhov muaj cov theem corundum ua kom muaj zog ntawm ob qho tib si chav tsev thiab qhov kub siab, thaum tseem muab kev tiv thaiv zoo rau cov kua qaub slag, iav molten, thiab lwm yam xov xwm. Txawm hais tias nws qhov kev tiv thaiv alkali qis dua me ntsis ntawm chrome corundum cib, nws muaj ntau yam kev siv.
3. Kev ua kom sov nruab nrab:Piv rau cov cib corundum uas muaj cov khoom siv siab, nws muaj cov thermal conductivity qis dua thaum tswj hwm qee qib ntawm kev rwb thaiv tsev, txo cov cua sov poob hauv cov khoom siv kub siab thiab ua rau nws tsim nyog rau cov ntawv thov uas xav tau kev rwb thaiv tsev thermal.
