Lus Cim: Cov pa oxygen hauv cov hlau molten muaj qhov cuam tshuam tseem ceeb rau qhov zoo ntawm cov hlau molten, yield, thiab noj tus nqi thiab ferroalloy.Raws li cov txheej txheem ntawm rimmed steel, sib npaug hlau, tsis tu ncua cam khwb cia hlau nrog aluminium deoxidation thiab sab nraud refining thev naus laus zis ntawm molten steel tau dav siv, nws yog qhov ceev kom xam cov ntsiab lus oxygen hauv cov hlau molten hauv txoj kev nrawm, raug thiab ncaj qha, yog li raws li kev tswj hwm steelmaking kev ua haujlwm, txhim kho kom zoo, thiab txo kev siv.
Txhawm rau ua kom tau raws li qhov xav tau ntawm cov khoom siv saum toj no, oxygen sojntsuam yog tsim los ua ib hom kev tshawb nrhiav metallurgy ntawm kev ntsuas cov pa oxygen hauv cov hlau molten thiab qhov kub ntawm cov hlau molten.
1, Kev siv:
Siv rau LF, RH thiab lwm qhov chaw kho kom zoo nkauj, cov pa oxygen sojntsuam ntsuas cov pa oxygen tuaj txog ntawm cov chaw nres tsheb thiab hauv cov txheej txheem kho, uas tuaj yeem lav qhov deoxidizer ntxiv, txo lub sijhawm ua kom zoo dua qub, pab tsim ntau yam tshiab, txhim kho thev naus laus zis, thiab txhawb nqa steel purity.
2, Lub ntsiab nta thiab ntau yam ntawm daim ntawv thov
Oxygen sojntsuam muaj ob hom: siab oxygen sojntsuam thiab qis oxygen sojntsuam.Tus qub yog
siv los ntsuas qhov kub thiab txias cov ntsiab lus ntawm molten steel hauv converter, hluav taws xob rauv, refining rauv.Tom qab ntawd yog siv los ntsuas qhov kub thiab txias cov ntsiab lus ntawm cov hlau molten hauv LF, RH, DH, tundish, thiab lwm yam.
3, Qauv
4, Txoj Cai:
"Solid dielectric concentration cell oxygen-cov ntsiab lus kuaj thev naus laus zis" tau siv rau hauv oxygen sojntsuam, uas tso cai rau ntsuas qhov kub thiab txias cov ntsiab lus ntawm cov hlau molten tib lub sijhawm.Oxygen sojntsuam muaj ib nrab-cell thiab thermocouple.
Khoom dielectric concentration cell oxygen-cov ntsiab lus kuaj yog tsim los ntawm ob ib nrab ntawm tes.nyob rau hauv ib qho yog paub siv cell ntawm oxygen ib nrab siab, thiab lwm yam yog cov hlau molten.Ob lub hlwb ib nrab txuas nrog cov pa oxygen ions khoom electrolyte, tsim kom muaj oxygen concentration cell.Cov ntsiab lus oxygen tuaj yeem xam los ntawm kev ntsuas cov pa oxygen thiab qhov kub thiab txias.
5, Feature:
1) Kev ua haujlwm ntawm cov pa oxygen ntawm cov hlau molten tuaj yeem ntsuas ncaj qha thiab nrawm, uas yuav pab tau txiav txim siab tus nqi ntawm deoxidizing tus neeg sawv cev, thiab hloov pauv kev ua haujlwm ntawm deoxygenation.
2) Cov pa oxygen sojntsuam yog yooj yim rau kev khiav lag luam.Kev ntsuas cov txiaj ntsig tuaj yeem tau txais tsuas yog 5-10s tom qab muab tso rau hauv cov hlau molten.
