Cib Corundum / Cib Corundum Mullite
Cov Ntaub Ntawv Khoom
Pob zeb Corundums yog cov khoom refractory nrog corundum ua lub ntsiab crystalline theem, thiab alumina cov ntsiab lus tshaj 90%.
Kev faib tawm:Cov cib corundum feem ntau yog muab faib ua cov cib corundum sintered thiab cov cib fused corundum. Cov thawj yog ua los ntawm sintered alumina, thaum qhov kawg yog ua los ntawm fused corundum. Cov cib corundum tsis tau hlawv kuj tuaj yeem ua tau siv phosphoric acid lossis lwm yam binders.
Cov yam ntxwv ntawm kev ua tau zoo:
Cov Khoom Siv Refractory Zoo Kawg Nkaus:Qhov kub ntawm cov cib corundum uas mos thaum thauj khoom ntau tshaj 1700 ° C, thiab qee cov cib chrome corundum tuaj yeem ncav cuag qhov kub tshaj 1790 ° C. Lawv nyob ruaj khov hauv qhov chaw kub siab thiab tsis yooj yim rau kev hloov pauv lossis kev puas tsuaj.
Muaj Zog Siab:Lub zog compressive ntawm cov cib corundum siab-purity ntawm chav tsev kub feem ntau yog 70MPa-100MPa, thaum cov cib chrome corundum ua tau zoo tshaj 150MPa thiab tuaj yeem ncav cuag txog 340MPa.
Kev Ruaj Ntseg Tshuaj Zoo:Cov cib corundum muaj zog heev rau cov kua qaub lossis alkaline slags, hlau, thiab iav molten, thiab tsis yooj yim rau cov tshuaj lom neeg.
Muaj zog tiv taus slag erosion:Piv txwv li, cov ntsiab lus Cr₂O₃ hauv cov cib chrome corundum zoo tiv thaiv cov slag molten los ntawm kev nkag mus rau hauv lub cev cib los ntawm cov qhov capillary, ua rau muaj kev tiv thaiv slag zoo dua li cov cib corundum ib txwm muaj.
Cov Khoom Xyaw Tseem Ceeb thiab Cov Khoom Siv Raw:
Cov khoom tseem ceeb ntawm cov cib corundum yog alumina (Al₂O₃), feem ntau tshaj 90%, nrog rau qee qhov muaj txog li 99%. Cov ntaub ntawv raw suav nrog sintered alumina thiab fused corundum. Lwm cov ntaub ntawv minerals kuj tuaj yeem ntxiv rau cov ntaub ntawv sib xyaw, xws li Cr₂O₃ rau chrome corundum cib thiab ZrO₂ rau zirconium corundum cib.
Cov cib corundum-mulliteyog cov cib refractory sib xyaw ua ke uas muaj ob theem kub thiab ruaj khov: corundum (Al₂O₃) thiab mullite (3Al₂O₃・2SiO₂). Lawv muab lub zog siab ntawm corundum nrog rau kev tiv thaiv thermal zoo heev ntawm mullite, ua rau lawv yog cov khoom siv kub thiab txias uas sib npaug kev ua tau zoo thiab kev siv nyiaj tsim nyog.
Cov Cheebtsam Tseem Ceeb thiab Cov Qauv
Cov Khoom Siv Crystalline Tseem Ceeb:Corundum thiab mullite yog ob lub ntsiab crystal theem, nrog rau cov ntsiab lus alumina feem ntau yog li ntawm 70% txog 90%, thiab cov seem feem ntau yog silicon dioxide (SiO₂). Qhov kev sib koom ua ke ntawm ob theem ua rau kev ua tau zoo sib npaug.
Cov qauv me me:Cov theem Mullite raug faib tawm ntawm cov noob corundum hauv daim ntawv ntawm cov koob zoo li rab koob lossis cov pob zeb columnar, tsim cov qauv "corundum skeleton + mullite connection". Qhov no tsis yog tsuas yog ua kom lub cib muaj zog xwb tab sis kuj tseem tiv thaiv kev ntxhov siab thermal los ntawm cov qhov sib txawv me me.
Cov txiaj ntsig tseem ceeb ntawm kev ua tau zoo
Kev tiv thaiv thermal 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.
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.
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.
