AZS Cib
AZS fused cib, tseem hu ua fused zirconium corundum cib, yog cov khoom siv refractory ua tau zoo. AZS fused cib feem ntau yog tsim los ntawm cov hmoov alumina ntshiab, zirconium oxide (ZrO2 txog 65%) thiab silicon dioxide (SiO2 txog 34%) thiab lwm yam khoom siv raw. Tom qab yaj ntawm qhov kub siab hauv lub cub hluav taws xob, nws raug txhaj rau hauv pwm thiab txias.
Cov txheej txheem tsim khoom:Cov xuab zeb zircon xaiv thiab hmoov alumina kev lag luam raug sib xyaw ua ke hauv qee qhov sib piv (feem ntau yog 1: 1), thiab me me ntawm Na2O (ntxiv rau hauv daim ntawv ntawm sodium carbonate) thiab B2O3 (ntxiv rau hauv daim ntawv ntawm boric acid lossis borax) raug ntxiv ua flux. Tom qab sib tov sib npaug, nws raug yaj ntawm qhov kub siab (xws li 1800 ~ 2200 ℃) thiab pov rau hauv cov duab. Tom qab txias, nws raug txiav thiab ua tiav los ua AZS fused cib nrog cov duab thiab qhov ntau thiab tsawg tshwj xeeb.
Cov yam ntxwv tseem ceeb ntawm cov khoom:
1. Kev tiv taus kub heev:Tsim los ntawm kev siv hluav taws xob ntawm 1800 ~ 2200 ℃, nws muaj qhov refractoriness siab dua li cov cib refractory ib txwm muaj thiab qhov kub siab ua kom mos. Nws tuaj yeem ua haujlwm ruaj khov rau lub sijhawm ntev hauv qab qhov kub siab ua haujlwm yaj tsis muaj qhov pom tseeb creep deformation.
2. Kev tiv thaiv xeb zoo heev:Nws muaj zog tiv taus kev yaig thiab kev xeb rau cov iav molten, acidic slag, cov pa roj kub siab, thiab lwm yam. Nws tuaj yeem tiv taus kev xeb tshuaj lom neeg thiab kev hnav lub cev ntawm cov khoom molten, ua rau lub neej kev pabcuam ntawm cov khoom siv linings ntev dua.
3. Cov qauv ntom thiab sib xws:Cov txheej txheem electrofusion ua rau muaj cov qauv sab hauv thiab cov khoom sib xws ntawm lub cib, tsis muaj qhov tsis zoo xws li qhov hws thiab tawg. Nws muaj qhov ceev ceev, nqus dej tsawg thiab ua kom sov tau ruaj khov, txo qhov kev pheej hmoo ntawm cov qauv tawg ntawm qhov kub siab.
4. Kev ntsuas qhov tseeb ntawm qhov ntev:Kev txiav kom raug yog ua tom qab txias thiab tsim, nrog rau cov qauv txheem thiab cov qauv tshwj xeeb uas tuaj yeem hloov kho tau. Lub cib muaj qhov tiaj tiaj thiab qhov yuam kev me me, hloov kho rau qhov xav tau ntawm ntau lub qhov cub thiab txo qhov nyuaj ntawm kev tsim kho.
5. Kev ruaj khov zoo ntawm thermal:Nws tuaj yeem hloov kho rau qhov hloov pauv ntawm qhov txias thiab cua sov hauv qab qhov kub siab ua haujlwm nrog cov coefficient thermal nthuav dav tsim nyog. Nws tsis yooj yim tawg lossis tawg vim muaj kev hloov pauv kub sai, ua kom ntseeg tau tias cov qauv ntawm lub qhov cub.

AZS-33:Qhov microstructure ntom ntom ntawm AZS33 ua rau cov cib muaj kev tiv thaiv zoo rau kev yaig ntawm cov kua iav, thiab nws tsis yooj yim los tsim cov pob zeb lossis lwm yam tsis zoo hauv lub qhov cub iav. Nws yog cov khoom siv dav hauv cov cub tawg iav, thiab feem ntau yog qhov tsim nyog rau cov qauv sab saud ntawm lub pas dej yaj, lub pas dej phab ntsa cib thiab cov cib paving ntawm lub pas dej ua haujlwm, thiab pem hauv ntej, thiab lwm yam.
AZS-36:Ntxiv rau qhov muaj tib lub eutectic li AZS33, AZS36 cib muaj ntau cov siv lead ua zirconia zoo li saw hlau thiab cov ntsiab lus iav qis dua, yog li qhov kev tiv thaiv corrosion ntawm AZS36 cib tau txhim kho ntxiv, yog li nws tsim nyog rau cov kua iav nrog cov nqi ntws sai dua lossis thaj chaw kub dua.
AZS-41:Ntxiv rau eutectics ntawm silica thiab alumina, nws kuj muaj cov zirconia crystals uas faib sib npaug ntau dua. Hauv lub zirconium corundum brick system, nws muaj kev tiv thaiv corrosion zoo. Yog li ntawd, cov khoom tseem ceeb ntawm lub qhov cub iav raug xaiv los sib npaug lub neej ntawm cov khoom no nrog lwm qhov.
