Lub qhov hluav taws xob dej ntawm lub refractory ladle yog ib qho tseem ceeb hauv kev tsim metallurgical. Lub qhov hluav taws xob ruaj khov ntawm lub qhov hluav taws xob pab ua kom zoo ntawm cov khoom siv hlau. Tom ntej no, peb yuav qhia kom meej cov yam ntxwv ntawm zirconia nozzle rau lub ladle nozzle.
1. Zoo heev kub ua hauj
Ib qho txiaj ntsig zoo ntawm kev siv zirconia nozzles rau refractory ladle nozzles yog nws qhov kub thiab txias tsis kam. Cov khoom siv zirconia nozzle yuav tsis nthuav dav ntawm qhov kub thiab txias, yog li nws yuav tsis cuam tshuam rau kev sib khi ntawm lub ladle dej inlet. Nws cov ntsiab lus melting yog siab thiab ruaj khov, yog li cov khoom siv zirconia nozzle yuav tsis yaj lossis deform ntawm qhov kub thiab txias.
2. Muaj zog corrosion kuj
Cov khoom siv zirconia nozzle muaj kev tiv thaiv corrosion zoo heev thiab yuav tsis raug puas tsuaj txawm tias yaig los ntawm cov pa roj, kua qaub lossis alkaline. Qhov no yog ib qho tseem ceeb tshwj xeeb tshaj yog thaum siv lub ladle nozzle, vim hais tias lub ladle nozzle feem ntau nyob rau hauv kev sib cuag nrog kub, acidic los yog alkaline tshuaj. Kev tiv thaiv corrosion ntawm zirconia nozzle tuaj yeem ua haujlwm ruaj khov ntawm lub taub hau ntev ntev.
3. Kev ua haujlwm zoo sealing
Nyob rau hauv cov nqe lus ntawm sealing lub ladle nozzle, lub zirconia nozzle muaj kev ua tau zoo heev. Lub zirconia nozzle sib koom ua ke nrog kev sib koom ua ke ntawm lub ladle dej inlet nws tus kheej los xyuas kom meej lub sealing ntawm lub ladle dej inlet, yog li yuav tsis muaj teeb meem xws li to. Tsis tas li ntawd, lub zirconia nozzle tuaj yeem hloov kho rau qhov deformation ntawm lub ladle nozzle, tso cai rau lub ladle nozzle tuav lub foob zoo rau lub sijhawm ntev.
4. Zoo thermal shock tsis kam
Cov khoom siv zirconia nozzle muaj qhov zoo thermal poob siab thiab yuav tsis ua rau tawg lossis tawg txawm tias tom qab txias ntawm qhov kub thiab txias. Lub ladle nozzle feem ntau dhau los ua cov txheej txheem ntawm kev hloov kub thiab txias thaum lub sijhawm tsim khoom. Qhov zoo thermal poob siab tsis kam ntawm zirconia nozzle tuaj yeem ua kom lub sijhawm ntev - siv cov ladle nozzle.
5. Cov txheej txheem tsim khoom yooj yim
Cov txheej txheem ntawm cov khoom siv zirconia nozzle yog yooj yim heev. Txoj kev zoo tshaj plaws yog siv graphite pwm nias lossis zoo li qub siab molding, thiab tom qab ntawd tawg nws kom tau txais cov khoom zoo li zirconia nozzle. Cov txheej txheem tsim khoom yooj yim tuaj yeem tsis tsuas yog ua kom cov khoom sib xws thiab ruaj khov, tab sis kuj txo cov nqi tsim khoom thiab txhim kho cov khoom sib tw.
6. Muaj kev nyab xeeb, ruaj khov thiab txhim khu kev qha
Txij li cov khoom siv zirconia nozzle yuav tsis hnov mob rau qhov kub thiab txias, acidic lossis alkaline tshuaj nyob rau hauv lub ladle nozzle, nws yuav tsis tsim teeb meem gases thiab yaj cov khoom, kom muaj kev ruaj ntseg, stability thiab kev ntseeg siab ntawm cov txheej txheem ntau lawm.
Piv txwv li, cov yam ntxwv ntawm zirconia nozzle rau ladle nozzle yog qhov zoo heev. Nws qhov kub thiab txias tsis kam, corrosion kuj, zoo sealing, muaj zog thermal poob siab tsis kam, yooj yim txheej txheem ntau lawm, kev nyab xeeb, ruaj khov thiab kev ntseeg tau ua rau zirconia nozzle ua cov khoom nrov tshaj plaws rau ladle nozzle. ib tug ntawm cov neeg sawv cev tseem ceeb. Nyob rau yav tom ntej, nrog kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis tsis tu ncua, daim ntawv thov kev lag luam thiab kev cia siab ua lag luam ntawm zirconia nozzle cov ntaub ntawv yuav dhau los ua dav. Peb tau cog lus los muab cov neeg siv khoom nrog cov khoom zoo tshaj plaws refractory, zirconia core thiab lwm yam ntaub ntawv refractory. Yog tias tsim nyog, tiv tauj peb hnub no thiab cia peb pab koj nrhiav kev daws teeb meem zoo rau koj cov kev xav tau!
