Dab tsi yog qhov cuam tshuam corrosion ntawm carbon raws li cov khoom siv refractory siv hauv ladles?
Ladle yog cov cuab yeej tseem ceeb hauv cov txheej txheem steelmaking, thiab nws cov khoom siv hauv ob sab phlu feem ntau yog tsim los ntawm cov khoom siv refractory. Cov ntaub ntawv no tuaj yeem corrode ntawm qhov kub thiab txias, ua rau lub neej luv luv.
Cov txheej txheem corrosion ntawm cov khoom siv refractory feem ntau suav nrog cov hauv qab no:
Tshuaj tua kab mob: Thaum kub kub, carbon raws li refractories react chemically nrog cov khoom nyob rau hauv molten steel los tsim corrosive gases los yog melts, ua rau puas tsuaj rau cov khoom nto.
Lub cev yaig: Thaum qhov kub thiab txias, cov pa roj carbon monoxide hauv cov khoom siv hluav taws xob yuav ua rau cov pa roj carbon monoxide hauv cov hlau molten los tsim cov pa roj carbon monoxide lossis CO₂, ua rau tawg thiab tev ntawm cov khoom siv.
Mechanical erosion: Thaum molten steel ntws nyob rau hauv lub ladle, nws yuav tsim mechanical yaig ntawm cov ntaub ntawv hauv ob sab phlu, ua rau nto hnav thiab tev ntawm cov khoom.
Txhawm rau txhim kho lub neej kev pabcuam ntawm lub ladle, kev tshawb fawb tob txog kev txhim kho corrosion ntawm cov khoom siv refractory yog xav tau. Qhov no tuaj yeem ua tiav los ntawm:
Xaiv cov ntaub ntawv uas muaj kev tiv thaiv corrosion zoo heev: Txhim kho corrosion kuj ntawm carbon raws li refractories los ntawm kev txhim kho cov khoom muaj pes tsawg leeg thiab kev npaj txheej txheem.
Optimize ladle tsim: Los ntawm kev txhim kho cov qauv tsim ntawm lub ladle, cov nyhuv yaig ntawm cov hlau molten ntawm cov khoom siv hauv ob sab phlu yog txo.
Tswj kev khiav hauj lwm tej yam kev mob: Los ntawm kev tswj cov kev khiav hauj lwm tej yam kev mob nyob rau hauv lub steelmaking txheej txheem, cov tshuaj erosion ntawm molten hlau nyob rau hauv ob sab phlu khoom yog txo.
Los ntawm kev xaiv cov khoom siv nrog kev txhim kho corrosion zoo, ua kom zoo dua ntaiv tsim thiab tswj kev ua haujlwm, nws yog tus yuam sij rau kev ua haujlwm zoo ntawm ladles.
