Lwm qhov zoo dua ntawm refractory ladle nozzles yog lawv qhov kev tawm tsam los ntawm cov hlau molten. Thaum lub sij hawm steelmaking txheej txheem, molten steel yog corrosive heev, thiab cov ntaub ntawv zoo tib yam tsis tuaj yeem tiv taus cov xwm txheej hnyav. Tab sis kev sib xyaw ua ke ntawm cov ntaub ntawv nozzle yog resistant rau corrosion, ua rau lawv xaiv zoo heev rau steel mills.
Sab saum toj thiab hauv qab ladle nozzles yog ib feem tseem ceeb ntawm steelworks. Cov nozzles yog tsim los xyuas kom meej tias cov hlau molten yog nchuav yooj yim rau hauv cov pwm sib txawv, tsis muaj kab mob. Sab saum toj ladle nozzle yog siv los ncuav cov hlau los ntawm lub ladle, thaum lub hauv qab nozzle yog siv los tswj cov ntws ntawm cov hlau molten. Nov yog qee qhov kev siv rau saum thiab hauv qab ladle nozzles:
1. Sab saum toj ladle nozzle
Sab saum toj ladle nozzles ua lub luag haujlwm tseem ceeb hauv cov txheej txheem steelmaking, kom ntseeg tau tias cov yaj yog nchuav tawm yam tsis muaj paug. Nws yog siv los tswj tus nqi ntws ntawm cov hlau molten thiab tiv thaiv kom tsis txhob kub thaum lub sij hawm nchuav. Tsis tas li ntawd, lub nozzle pab tswj qhov kub ntawm cov hlau, kom ntseeg tau tias nws yog poured ntawm qhov kub thiab txias. Qhov no yog qhov tseem ceeb kom ua tiav cov khoom zoo steel.
2. Hauv qab ladle nozzle
Hauv qab ladle nozzles yog siv los tswj qhov ntws ntawm cov hlau molten rau hauv cov pwm sib txawv. Nws yog siv los tswj tus nqi ntws ntawm cov hlau molten thiab xyuas kom meej tias cov hlau yog nchuav nrog tsawg lossis tsis muaj pov tseg. Hauv qab ladle nozzles kuj tseem ceeb heev rau kev tswj xyuas qhov zoo thiab sib xws ntawm cov qib tsim.
Cov lus qhia ntxaws ntxaws ntawm refractory ladle nozzle
Refractory ladle nozzles yog tsim los ntawm kev sib xyaw ntawm cov ntaub ntawv xws li alumina, av nplaum thiab silicon carbide. Qhov kev xaiv ntawm cov khoom yog nyob ntawm qhov tshwj xeeb daim ntawv thov thiab cov kev cai ntawm cov txheej txheem steelmaking. Ladle nozzles yog tsim los tiv taus kub txog 1700 degree lossis ntau dua, nyob ntawm cov khoom siv hauv lawv cov kev tsim kho.
Refractory ladle nozzles yog thermal shock resistant, txhais tau hais tias lawv tuaj yeem tiv taus qhov kub thiab txias hloov tsis tau tawg lossis tawg. Qhov no yog ua tiav los ntawm kev ua tib zoo xaiv cov ntaub ntawv thiab cov txheej txheem tsim khoom los tsim cov khoom lag luam uas tuaj yeem tiv taus cov kev ntxhov siab thaum siv.
Hauv kev xaus
Hauv kev xaus, refractory ladle nozzles ua lub luag haujlwm tseem ceeb hauv cov txheej txheem steelmaking. Lawv qhov zoo muaj xws li kub tsis kam, tsis kam rau molten steel nres thiab siab mechanical zog. Lawv yog ib qho tseem ceeb ntawm steelworks, nrog rau sab saum toj thiab hauv qab variants siv los nchuav tawm hlau tsis muaj paug thiab tswj cov ntws mus rau hauv cov pwm sib txawv. Nkag siab txog qhov tseem ceeb ntawm refractory ladle nozzles yog qhov tseem ceeb los xyuas kom meej tias cov khoom siv hlau zoo.
