Ladle Nozzle Upper Alumina Zro2 Nozzle
Ladle qaum nozzles yog ib qho tseem ceeb ntawm cov txheej txheem steelmaking, pab kom ntseeg tau tias cov khoom kawg ua tau raws li cov qauv zoo uas yuav tsum tau ua los ntawm cov tuam txhab thiab cov neeg siv khoom.

Kev piav qhia
Ladle qaum nozzles yog ib hom refractory tivthaiv siv nyob rau hauv cov txheej txheem steelmaking. Lawv feem ntau ntsia rau saum lub ladle, uas yog lub thawv loj siv rau kev thauj thiab nchuav hlau molten.
Lub ladle qaum nozzle ua haujlwm rau ntau yam haujlwm tseem ceeb. Ua ntej, nws pab tswj cov dej ntws ntawm cov hlau molten raws li nws tau nchuav tawm ntawm lub ladle, kom ntseeg tau tias nws tau xa mus zoo thiab tsis tu ncua. Qhov thib ob, nws pab tiv thaiv kev tsim ntawm slag, uas yog ib qho khoom siv los ntawm cov txheej txheem steelmaking uas tuaj yeem txo qhov zoo ntawm cov khoom kawg. Thaum kawg, lub nozzle pab tiv thaiv oxidation ntawm cov hlau molten, uas tuaj yeem cuam tshuam qhov zoo ntawm cov hlau.
Ladle sab saum toj nozzles feem ntau yog tsim los ntawm cov khoom siv hluav taws xob zoo xws li alumina, magnesia, lossis zirconia. Cov ntaub ntawv no muaj cov thermal poob siab zoo heev, uas txhais tau hais tias lawv tuaj yeem tiv taus qhov kub thiab txias hloov ceev uas tshwm sim thaum lub sij hawm steelmaking txheej txheem. Lawv kuj yog cov tshuaj inert, uas pab tiv thaiv kom txhob muaj kab mob ntawm cov hlau molten.
