Refractory Tundish Nozzle Lower Nozzle
Lub refractory tundish nozzle qis nozzle yog ib qho tseem ceeb tivthaiv siv nyob rau hauv nruam casting txheej txheem ntawm steel ntau lawm. Nws yog tsim los tswj cov ndlwg ntawm molten hlau los ntawm lub ladle rau hauv pwm, kom muaj kev tswj thiab du casting ua haujlwm. Ua los ntawm cov ntaub ntawv zoo refractory, lub hauv qab nozzle yog tsim los tiv taus kub thiab tiv taus hnav thiab yaig los ntawm cov hlau molten.
Khoom Description
Lub refractory tundish nozzle, tseem hu ua lub qis nozzle, yog ib qho tseem ceeb tivthaiv siv nyob rau hauv lub nruam casting txheej txheem ntawm steel ntau lawm. Nws yog nyob rau hauv qab ntawm lub tundish, uas yog ib tug nruab nrab ntawm lub nkoj ntawm lub ladle thiab pwm nyob rau hauv lub casting txheej txheem.
Lub hom phiaj tseem ceeb ntawm refractory tundish nozzle yog los tswj cov dej ntws ntawm cov hlau los ntawm lub ladle rau hauv pwm. Nws ua raws li lub valve, tswj cov hlau ntws tus nqi thiab ua kom muaj kev ua haujlwm du thiab tswj tau. Qhov qis nozzle raug kub siab thiab molten hlau, yog li nws yog tsim los ntawm cov khoom zoo refractory uas tuaj yeem tiv taus cov mob hnyav no.
Lub refractory tundish nozzle raug hnav thiab yaig vim qhov ntws ntawm cov hlau molten. Yog li ntawd, nws yog ib qho khoom siv uas yuav tsum tau hloov lub sijhawm. Qhov zaus ntawm kev hloov pauv nyob ntawm ntau yam xws li qib steel raug cam khwb cia, casting ceev, thiab tundish kev coj ua.

Khoom Zoo
Txhim kho Flow Control: Lub tundish qis nozzle tso cai rau kev khiav dej num ntawm cov hlau molten thaum lub sij hawm nruam casting txheej txheem. Qhov no ua rau muaj kev tswj xyuas zoo dua ntawm qhov nrawm nrawm thiab ua kom muaj qhov sib xws thiab sib xws, ua rau kev txhim kho cov khoom zoo.
Enhanced Steel Quality: Los ntawm kev tswj cov dej ntws ntawm cov hlau molten, lub tundish qis nozzle pab txo qis kev kub ntxhov thiab tswj cov ntsiab lus suav nrog hauv cov hlau. Qhov no ua rau cov khoom siv hlau zoo dua nrog kev ua kom huv huv thiab txo qhov tsis xws luag.
Kub thiab Tshuaj Tiv Thaiv: Tundish qis nozzles yog tsim los tiv thaiv qhov kub thiab txias thiab tiv thaiv cov tshuaj lom neeg nrog cov hlau molten thiab slag. Qhov no ua kom lawv ruaj khov thiab ua tau zoo txawm tias nyob rau hauv kev ua haujlwm nyuaj.
Kev ua tau zoo ib yam: Tundish qis nozzles, tsim ua raws li cov qauv kev lag luam thiab cov txheej txheem tswj kom zoo, muaj kev ua tau zoo thiab txhim khu kev qha. Lawv cov kev tsim kho zoo thiab kev tswj xyuas meej ua rau muaj txiaj ntsig zoo sib xws thiab txhim kho cov txheej txheem tag nrho.
Kev Tsim Nyog Muaj Peev Xwm: Nrog kev tswj xyuas zoo dua thiab txhim kho cov hlau zoo, kev siv lub tshuab qis qis tuaj yeem ua rau muaj txiaj ntsig ntau ntxiv hauv cov txheej txheem nruam casting. Nws tso cai rau ntau dua casting speeds, txo downtime rau kev txij nkawm, thiab txhim kho yield.
Cov khoom siv
Lub refractory tundish nozzle qis nozzle yog siv nyob rau hauv steel kev lag luam rau nruam casting txheej txheem. Nws pom cov ntawv thov hauv:
Steel Mills: Siv nyob rau hauv tundish ntawm nruam casting tshuab los tswj cov ndlwg ntawm molten hlau thaum lub sij hawm casting txheej txheem, kom ntseeg tau cov khoom zoo steel.
Foundries: Ua hauj lwm hauv kev lag luam uas yuav tsum tau nruam nruam cov hlau los tsim ntau yam khoom hlau xws li billets, slabs, thiab paj.
Hlau Fabrication: Siv nyob rau hauv cov txheej txheem hlau fabrication qhov twg nruam casting steel yog tsim nyog rau zus tau tej cov tshwj xeeb Cheebtsam thiab cov qauv.
Steel Recycling: Siv nyob rau hauv cov chaw uas rov ua dua cov hlau thiab tsim cov khoom hlau tshiab los ntawm txoj kev nruam nruam.
