Khoom Description
Nyob rau hauv lub ntiaj teb no ntawm casting, kev siv desulfurization cov neeg ua hauj tau dhau los ua ib qho tseem ceeb nyob rau hauv xyoo tas los no. Qhov no yog qhov twg ferromanganese tuaj rau hauv daim duab, vim nws yog ib qho ntawm cov neeg ua haujlwm zoo tshaj plaws desulfurization muaj nyob hauv khw niaj hnub no.
Ferromanganese yog ib hom hlau alloy uas feem ntau muaj li ntawm 75% manganese thiab 25% hlau. Nws yog feem ntau siv nyob rau hauv steel ua, tab sis nws kuj tau pom ib daim ntawv thov nyob rau hauv lub ntiaj teb no ntawm casting. Nws cov khoom desulfurization ua rau nws muaj txiaj ntsig ntxiv rau cov txheej txheem casting, vim nws tuaj yeem pab tshem tawm cov sulfur los ntawm cov hlau molten thiab txo qhov tsim ntawm cov teeb meem sib txuas.
Ib qho txiaj ntsig tseem ceeb ntawm kev siv ferromanganese ua tus neeg sawv cev desulfurization yog nws lub peev xwm ua haujlwm sai thiab zoo. Thaum ntxiv rau cov hlau molten, ferromanganese reacts nrog sulfur los tsim manganese sulfide, uas tom qab ntawd tshem tawm ntawm cov hlau los ntawm slag. Cov txheej txheem no tuaj yeem tshwm sim hauv ob peb feeb, nyob ntawm qhov kub thiab txias ntawm cov hlau, uas ua rau nws muaj txiaj ntsig zoo thiab txhim khu kev qha ntawm desulfurization.
Lwm qhov zoo ntawm kev siv ferromanganese yog nws tus nqi qis, piv rau lwm cov tshuaj desulfurization. Qhov no ua rau nws yog qhov kev xaiv zoo nkauj rau cov chaw tsim khoom me me thiab kev ua haujlwm casting uas yuav tsis muaj peev txheej los nqis peev hauv cov khoom kim dua.
Tsis tas li ntawd, ferromanganese kuj tuaj yeem hloov kho kom haum rau cov kev xav tau tshwj xeeb. Piv txwv li, qhov sib txawv ntawm cov ntsiab lus ntawm manganese tuaj yeem hloov cov khoom desulfurization ntawm cov hlau, ua kom nws tshem tawm cov sulfur los ntawm ntau hom hlau thiab alloys. Qhov kev ua tau zoo no ua rau ferromanganese yog ib qho cuab yeej tseem ceeb hauv cov txheej txheem casting, tso cai rau kev tswj ntau dua thiab hloov pauv hauv cov txheej txheem ntau lawm.
Zuag qhia tag nrho, kev siv ferromanganese ua tus neeg sawv cev desulfurization hauv cov txheej txheem casting tuaj yeem nqa tau ntau yam txiaj ntsig rau lub rooj. Los ntawm kev tshem tawm cov sulfur los ntawm cov hlau molten, ferromanganese tuaj yeem pab txhim kho qhov zoo ntawm cov khoom kawg, txo qhov kev pheej hmoo ntawm qhov tsis xws luag thiab txhim kho tag nrho cov txheej txheem casting efficiency.
Yog li ntawd, nws tsis yog qhov xav tsis thoob tias ferromanganese tau dhau los ua neeg nyiam hauv kev lag luam casting hauv xyoo tas los no. Nws cov nqi pheej yig, kev ua tau zoo thiab kev yooj yim ua rau nws yog ib qho cuab yeej tseem ceeb rau cov chaw tsim khoom thiab kev ua haujlwm ntawm txhua qhov ntau thiab tsawg, thiab nws zoo li yuav yog qhov tseem ceeb ntawm cov txheej txheem casting rau xyoo tom ntej.
