Yuav tiv thaiv nozzle thaiv li cas thaum nruam casting?
Apr 20, 2026
Hauv kev nruam casting ntau lawm,nozzle thaivtseem yog ib qho kev sib tw tseem ceeb cuam tshuam rau kev tsim khoom txuas ntxiv, kev ua haujlwm zoo, thiab cov nqi ua haujlwm. Tshwj xeeb tshaj yog nyob rau hauv lub casting ntawm txhuas-tua hlau, stainless hlau, thiab siab- qib tshwj xeeb steels, siab- melting- taw tes inclusions xws li Al₂O₃ yooj yim adhere thiab accumulate nyob rau hauv lub puab phab ntsa ntawm nozzles. Qhov no ua rau cov dej ntws qis, tsis ruaj khov molten steel ntws, thiab txawm tias cuam tshuam rau casting, online nozzle hloov, thiab txo cov khoom tsim tau.
Nrog ntau xyoo ntawm kev txawj ntse nyob rau hauv kev tsim nruam casting refractories, Changtai Zirconia muab kev daws teeb meem los tiv thaiv nozzle blockages los ntawm qhov chaw. Los ntawm kev sib xyawkev txhim kho cov khoom siv, kev ua kom zoo dua qub, thiab cov txheej txheem sib txuam, peb xa cov khoom txhim khu kev qha suav nrogzirconia metering nozzles, submerged nkag nozzles (SEN), thiab ceev - hloov tundish nozzleslos txhawb kev ruaj khov, ntev - voj voog ua haujlwm nruam casting.
Qhov Tseem Ceeb Ntawm Nozzle Thaiv
- Adhesion ntawm siab - melting -point inclusionsAl₂O₃ thiab calcium aluminate inclusions yooj yim tso thiab tsim deposits ntawm nozzle phab ntsa.
- Secondary oxidation thiab slag entrapmentKev sib cuag nrog huab cua thiab kev nkag ntawm pwm hmoov ua kom muaj kev sib txuas ntxiv thiab ua kom nrawm nrawm.
- Cov ntaub ntawv tsis ruaj tsis khov nozzleIb txwm siv alumina-graphite nozzles zoo li ua rau cov hlau molten thiab muaj qhov ntxhib hauv sab hauv, ua rau cov khoom sib txuas ntau dua.
- Tsis zoo flow field designCov chaw tuag, eddies, thiab tsis ruaj tsis khov tshaj tawm txhawb kev sib sau ua ke.
- Kub hloov pauv thiab tsis txaus preheatingTsawg superheat thiab tsis txaus nozzle ci ua rau cov hlau tsis muaj zog los tsim cov blockages.
Changtai's Anti-Clogging Solutions
1. High-Stability Anti-Clogging Materials
Peb cov nruam casting nozzles sivsiab -purity stabilized zirconia (ZrO₂)raws li cov khoom tseem ceeb, tsim los ntawm kev tsim tshwj xeeb thiab siab -kub sintering. Cov txiaj ntsig tseem ceeb muaj xws li:
- Muaj zog tshuaj inertness- tsis muaj cov tshuaj tiv thaiv nrog cov hlau molten lossis slag, zam cov tshuaj tiv thaiv -raws li blockages.
- Nthuav thiab du sab hauv phab ntsa- zoo heev txo adhesion ntawm inclusions.
- Zoo heev erosion thiab corrosion kuj- tuav txoj hauv kev zoo tshaj qhov kev sib tw ua yeeb yam ntev.
Rau kev txhaws- cov qib hlau tsis zoo, peb muabZrO₂-CaO composite nozzlesuas hnov mob nrog deposited Al₂O₃ kom tsim tsawg- melting theem, uas yog ib txwm ntxuav tawm los ntawm molten steel, ua tiav ibtus kheej - ntxuav nyhuv.
2. Optimized Structure rau Stable Flow
Peb cov nozzles muaj cov qauv tsim tsim los tshem tawm cov chaw tuag thiab txo cov deposition:
- Isostatic pressing tshuab- Cov qauv zoo ib yam, tsis muaj delamination, tsis muaj pob qij txha, du sab hauv phab ntsa.
- Smooth transitional flow channels- txo qhov kub thiab txias qhov chaw.
- Integrated composite qauv- tsis muaj refractory mortar pob qij txha, tiv thaiv kom xau thiab deposit tsub zuj zuj.
- Argon tshuab tau tshaj tsim- Txhawb nqa cov ntsaws ntsaws los yog slit argon txhaj tshuaj los tsim cov yeeb yaj kiab tiv thaiv roj.
3. Txheej txheem-Matched Product Range
- Zirconia metering nozzles- siab qhov tseeb, tsis tshua muaj hnav tus nqi, ruaj khov txaus tswj, zoo tagnrho rau me me billet qhib casting.
- Ceev- hloov tundish nozzles- Kev hloov ceev ceev, kev sib dhos meej, txo qis qis thiab kub poob.
- Zirconia submerged nkag nozzles- zoo heev slag kab kuj, txhim khu kev qha tiv thaiv casting, txo oxidation theem nrab.
Ntawm -Qhov Kev Coj Zoo Tshaj Plaws rau Kev Tiv Thaiv Thaiv
- Uapuv -kev tiv thaiv castingnrog ntev nozzles thiab argon sealing kom cais tawm cua.
- Xyuas kom txausnozzle preheatingkom tsis txhob thermal shock thiab txias steel tsim.
- Khaws ruaj khovmolten steel superheatlos tiv thaiv kev ua kom muaj zog- cuam tshuam txog kev thaiv.
- Xaiv tushom nozzle tsim nyograws li qib steel, seem loj, thiab casting ceev.
- Ua raws li lub sijhawm tu thiab hloov pauv tsis tu ncua kom tsis txhob siv ntau dhau.
Yog tias koj nquag ntsib teeb meem xws li nozzle blockages, scaling, flow deviation, short service life, thiab nquag hloov hauv online thaum lub sij hawm nruam casting, thov koj xav tiv tauj. Anyang Changtai Silicon Kev Lag Luam.
