Ladle Nozzles (Ladle swb rooj vag) tuaj yeem faib ua ntau hom raws li lawv cov qauv, muaj nuj nqi thiab kev ua haujlwm thiab kev siv cov xwm txheej.
1. Kev faib tawm los ntawm cov qauv thiab ua haujlwm ntawm cov ntsiab cai
(1) Cov rooj vag poob lawm
Composition:Nws muaj cov ntaub qhwv sab saud thiab qis dua (cov khoom siv regractory) thiab kev tsav tsheb (hydraulic / tshuab). Tus ntws ntws ntawm Molten Steel raug kho lossis txiav tawm los ntawm tus txheeb ze zawv zawg ntawm cov kab ntawv swb.
Nta:
Tib Xaub Phaj: tswj tau los ntawm ib daim ntaub npog ib daim npog, cov qauv yooj yim, siv rau cov qib steel.
Ob Chav Swb Phaj: Ob khub ntawm cov phiaj slide yog superimposed rau kev sib khi zoo dua, haum rau cov hlau gasygen lossis cov hlau loj.
Daim ntawv thov: Lub ntsiab siv Flow Control txoj kev rau txuas ntxiv casting thiab tuag casting.
(2) Qeeb Muzzle
Lub ntsiab lus: Cov ntws ntawm cov hlau Molten tau hloov kho los ntawm kev sib hloov ntawm cov cib regractory nrog qhov (rotor).
Nta:
Txawm tias hnav, lub neej ntev, tab sis cov qauv sib txawv thiab kev txij nkawm siab.
Daim Ntawv Thov:Qee qhov me me thiab nruab nrab ntawm cov tiaj nyom lossis hom hlau tshwj xeeb.
(3) Qiv Qiv Quav
Lub hauv paus ntsiab lus:Qhov qhib thiab kaw ntawm lub nozzle yog tswj los ntawm kev nqa thiab txo qis tus pas dej nres ua los ntawm cov khoom siv refractory.
Cov yam ntxwv:
Kev hloov kho siab yog qhov tseeb, tab sis tus pas dej nres yog yooj yim tawg los ntawm Molten Steel thiab feem ntau siv rau kev tswj hwm tundish.
Daim Ntawv Thov:Tsoos tuag casting lossis billet casting.
2. Kev cais los ntawm kev ua haujlwm
(1) ib txwm muaj nozzle
Khoom siv: Aluminium-Carbon, High-Aluminium
Muaj nuj nqi: tswj kev ntws yooj yim, haum rau cov cim hlau dav dav
(2) ntev nozzle (ntev-caj dab)
Nta:txuas ntxiv hauv qab qib ntawm tundish kua saum npoo kom tiv thaiv kev tawg thiab nqus ntawm cov hlau molten.
Daim Ntawv Thov:Nruam Casting kev tiv thaiv pouring.
(3) Submerged nkag nozzle (Sen, submerged nkag nozzle)
Cov yam ntxwv:Tso rau hauv cov hlau molten nyob rau hauv lub tundish lossis pwm kom tiav cais tawm cov huab cua.
Hom:
Ncaj-los ntawm hom: Yooj yim nchuav.
Ntau hom(sab qhov / hauv qab): Ua kom zoo rau Mancen Steel ntws teb thiab txo qis slag untrainment.
Daim Ntawv Thov:Slab thiab billet txuas ntxiv txuas.
(4) roj-ntxuav tawm nozzle
Nta:Argon thiab lwm cov roj hauv plab yog qhia rau kev tiv thaiv kom tsis txhob muaj nozzle thaiv (piv txwv li, al₂o₃ outition) thiab hlau oxidation.
Daim Ntawv Thov:High-oxygen-rhiab hlau qib (piv txwv li aluminium tempered steel).
(5) tiv thaiv kev tiv thaiv nozzle
Tsim:Sab hauv phab ntsa yog coated nrog cov ntaub ntawv xws li Cao-Zro₂, lossis cov qauv tshwj xeeb (xws li cov nyom-hom-hom channel) yog siv.
Daim Ntawv Thov:High-aluminium hlau, silicon steel thiab lwm cov qib hlau uas nquag ua rau oxidation.
