Refractory Alumina Sib koom ua si lub cev pob txha pob txha hauv cov khoom loj me ntawm cov khoom siv refractory. Lawv yog cov ntaub ntawv granular nrog ib qho me me loj dua 0.088mm, ua los ntawm ntau cov khoom raw cais los ntawm kev ua haujlwm ref refractination, crushing ua, lossis khoom cuav. Kev tso siab yog cov khoom tseem ceeb hauv amorpholus refractory, feem ntau cov nyiaj txiag rau 60% rau 75% ntawm tag nrho cov pes tsawg leeg. Yog li ntawd, cov khoom siv ntawm amorphous refractory cov ntaub ntawv feem ntau yog muaj npe tom qab cov txiv hmab txiv ntoo ua kom muaj zog los yog cov khoom siv refractory, uas tau hu ua high alumina ramming cov ntaub ntawv.

3.Qhov kev thov Bauxite ntawm cov khoom xa rov qab hauv thaj teb refractory muaj qhov tseem ceeb heev nrog cov tseem ceeb- kub kev lag luam rau refractory kev lag luam. Cov txiaj ntsig tshwj xeeb tuaj yeem tsim los ntawm cov hauv qab no:
1, Zoo heev - kub kom tau raws li cov kev xav tau ib puag ncig
-High refractoriness: The alumina in calcined bauxite exists as stable crystal phases such as corundum (Al ₂ O Ⅲ) or mullite (3Al ₂ O Ⅲ · 2SiO ₂), with a refractoriness generally above 1770 ℃. Some high alumina grades (Al ₂ O Ⅲ>85%) kuj tseem tuaj yeem tiv thaiv kom kub siab tshaj 2000 degree, deb tshaj cov ntaub ntawv av nplaum refractory saud (1580 {{{}} 1770 degree). Nws tuaj yeem siv ncaj qha raws li cov khoom siv sab hauv rau cov khoom siv kub ultra
-}} muaj zog sintering sinter resistance: nws tsis yooj yim heev rau lwm yam kev kub siab, thiab tuaj yeem tswj hwm lub neej kev ua haujlwm ntawm cov ntaub ntawv refractory.
2, zoo meej heev cov kws kho tshuab txhim kho cov txheej txheem lub zog ntawm cov ntaub ntawv
{{0- Lub zog siab thiab ntom ntom, cov Alumina hais los ntawm Sintering, ua rau muaj kev txo qis hauv porosity (feem ntau<10%). The compressive strength can reach several hundred MPa, which is much higher than that of uncalcined alumina or ordinary refractory materials. The refractory bricks, castables and other products prepared with it can withstand mechanical impacts (such as material erosion, equipment vibration) and self weight pressure during kiln operation, reducing the risk of damage.
{{0-} * * Zoo hnav Tsis kam * *: Mohs hardness ncav 7 {}}} 8, ze rau corundum. Cov khoom siv refractory ua tau los ntawm cov khoom siv no muaj cov khoom siv uas muaj kev sib txhuam xws li cov cua sov thiab cov chaw siab hloov pauv thiab cov chaw hloov pauv hauv cov cub.
3, Zoo heev tshuaj muaj peev xwm, tiv taus rau corrosion thiab yaig
{{0- kua qaub thiab alkali corrosion resistance: cullite muaj cov pa roj acidic (xws li ₂, xws li Cao, Mgo) ntawm qhov kub. Lawv tuaj yeem tiv thaiv cov corrosion ntawm corrosive media hauv metallurgical thiab tshuajilms.
{{0- Tsis kam mus rau cov khoom siv hlau oxide, tsis txhob txo cov ntaub ntawv ntawm cov tsiaj hlau, tsis txhob muaj cov qauv siv roj av. Cov xeeb ceem no ua rau nws yog cov khoom siv tseem ceeb rau cov tshuab hluav taws xob ua kom sov huv si, txhaws lub tank thiab lwm yam khoom siv.
