Dab tsi ua rau muaj kev puas tsuaj rau zirconia nozzles?
Oct 25, 2025
Zirconia NozZlesyog hom hom ntawm tundish nozzle. Ua los ntawm high - kub-resistant zirconia, lawv tuaj yeem tiv taus Molten Steel tsis muaj kev txom nyem yooj yim. Txawm li cas los xij, cov hlau txuas txuas ntxiv yog ib qho txheej txheem nyuaj siab yog qhov kev ua phem zirzaum no yog tias kev ua haujlwm kom raug kom raug. Lub ntsiab ua rau lub ntsej muag zoo ntawm zirconia kev puas tsuaj tuaj yeem muab faib ua kev puas tsuaj ntawm lub cev thiab kev puas tsuaj.
Kev puas tsuaj lub cev
Thermal Shock puas tsuaj:
Thaum lub sij hawm Steel casting txheej txheem, zirconia no raug rau qhov kub thiab txias thiab cua sov sai. Tsis ncaj rau sab hauv qhov kub thiab txias faib cov ntsiab lus nozzle rau hnyav hnyav thermal. Qhov kev tsim kho no txo cov nozzle lub zog thiab kev yaig kuj, ua rau nws yooj yim dua rau cov hlau molten thiab sletring thiab corrode cov khoom.
Mechanical yaig puas:
Cov kev siv tshuab erosion tshwm sim los ntawm Molten Steel Flow kuj yog qhov tseem ceeb tshaj plaws. Txawm hais tias Molten hlau yog viscous, nws qhov siab ntom, kub, thiab nrawm tsim muaj zog thermal thiab mechanical cuam tshuam ntawm phab ntsa nozzle phab ntsa. Lub resulting ntsuas nyob thoob plaws nozzle ntu tsis muaj zog ntawm phab ntsa lub zog uas nws tiv tauj cov hlau.
Tshuaj lom neeg
Zirconia dislecution:
Lub ntsiab siv tshuaj muaj zog tseem ceeb ntawm cov zirconia yog zrozzle yog zrozzle yog zrozzle yog zrozzle yog zrozzle yog zrozzle yog zrozzle yog zrozzle yog zrozzle yog zrozzle yog zrozzle yog cov me me ntawm stabilizers (CAO, Y₂O₃, thiab kab mob impurities. Lub ntsej muag ntshiab zirconia undergoes ib martens theem hloov pauv ntawm monoclinal crystal Cryes ntawm 900-1200 degree, uas ua rau nws tsis tuaj yeem tsim cov khoom ntshiab zirconia.
Ntxiv rau cov neeg ua zirconia, muaj ntau lwm yam ntawm nozzles, xws li ntsuas nozzles thiab nrawm {0} Hloov pauv ntsuas cov ntsuas ntsuas. Txhawm rau txhim kho casting kev ua tau zoo, nrawm- hloov lub nozzle Technology tau kuj tau hais tseg.
Nyob ntawm qhov tshwj xeeb casting cov xwm txheej, cov kev qhia tshwj xeeb thiab hom zirconia no siv yuav sib txawv los xyuas kom meej.
Peb lub tuam txhab khoom siv ntau hom kev zirconia no.
