Khoom Description
Ferromanganese yog ib qho tseem ceeb alloy hauv kev lag luam steelmaking. Nws yog siv los ua deoxidizer thiab tus neeg sawv cev alloying hauv kev tsim cov hlau. Kev siv ferromanganese hauv steelmaking pab txhim kho cov hlau zoo, ua rau nws muaj zog thiab ruaj khov. Deoxidizer ferromanganese yog ib qho tseem ceeb tshwj xeeb hauv kev tsim cov hlau, vim nws pab tshem tawm pliaj impurities los ntawm cov hlau molten.
Deoxidizer ferromanganese yog tsim los ntawm kev sib txuas ntawm manganese ore, coke, thiab hlau ore hauv qhov cub tawg. Cov txheej txheem suav nrog cua sov cov ntaub ntawv raw mus rau qhov kub thiab txias thiab tom qab ntawd tso cai rau lawv sib cuam tshuam nrog ib leeg los tsim ferromanganese. Lub resulting alloy muaj ntau theem ntawm manganese thiab hlau, nyob ntawm seb cov kev cai tshwj xeeb ntawm cov txheej txheem steelmaking.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm deoxidizer ferromanganese yog nws lub peev xwm tshem tawm cov pa oxygen los ntawm cov hlau molten. Qhov no yog qhov tseem ceeb vim tias cov pa oxygen tuaj yeem cuam tshuam nrog lwm cov ntsiab lus hauv cov hlau los tsim cov khoom tsis zoo. Cov impurities no tuaj yeem ua rau cov hlau tsis muaj zog thiab ua kom tsis muaj zog. Deoxidizer ferromanganese ua haujlwm los ntawm kev sib txuas nrog cov pa oxygen hauv cov hlau los tsim manganese oxide. Cov oxide no ces muab tshem tawm los ntawm cov hlau, tawm hauv qab cov khoom zoo, tsis muaj impurity.
Lwm qhov txiaj ntsig ntawm deoxidizer ferromanganese yog nws lub peev xwm los ua kom lub zog thiab hardness ntawm hlau. Qhov sib ntxiv ntawm manganese rau hlau yuav pab txhim kho nws cov tawv nqaij thiab tsis kam hnav thiab tsim kua muag. Qhov no ua rau nws zoo tagnrho rau kev siv hauv kev lag luam uas muaj zog thiab kav ntev yog qhov tseem ceeb. Qhov tseeb ntawm ferromanganese ntxiv rau cov hlau yog nyob ntawm cov kev cai tshwj xeeb ntawm cov khoom tsim, tab sis feem ntau yog li ntawm 1% mus rau 15% ntawm tag nrho qhov hnyav.
Deoxidizer ferromanganese muaj ntau daim ntawv thov hauv kev lag luam steel. Nws yog feem ntau siv los ua tus neeg sawv cev alloying hauv kev tsim cov hlau muaj zog, xws li cov khoom siv hauv tsheb thiab cov khoom siv. Nws kuj tseem siv rau hauv kev tsim cov hlau tsis muaj steel, uas yuav tsum tau muaj cov manganese siab los tiv thaiv corrosion. Deoxidizer ferromanganese kuj tseem siv rau hauv kev tsim cov hlau tshwj xeeb, xws li cov khoom siv hauv kev lag luam aerospace, qhov uas yuav tsum tau muaj kev ua haujlwm siab.
Ntxiv rau nws siv hauv steelmaking, deoxidizer ferromanganese kuj muaj lwm yam kev siv. Nws yog siv los ua chiv hauv kev ua liaj ua teb, vim tias manganese yog ib qho tseem ceeb ntawm cov nroj tsuag kev loj hlob. Nws kuj yog siv rau hauv kev tsim cov roj teeb, qhov twg nws yog siv los ua ib feem ntawm cov cathode. Deoxidizer ferromanganese kuj tseem siv rau hauv kev tsim cov vuam rods, qhov uas nws pab tsim kom muaj zog, ruaj welds.
Zuag qhia tag nrho, deoxidizer ferromanganese yog ib qho tseem ceeb hauv kev lag luam steelmaking. Nws muaj peev xwm tshem tawm impurities los ntawm cov hlau molten thiab ua kom lub zog thiab kav ntev ntawm cov hlau ua rau nws yog ib feem tseem ceeb ntawm cov txheej txheem tsim khoom. Nrog nws ntau daim ntawv thov, deoxidizer ferromanganese plays lub luag haujlwm tseem ceeb hauv ntau qhov kev lag luam sib txawv. Raws li qhov kev thov rau cov hlau zoo txuas ntxiv mus ntxiv, yog li yuav qhov kev thov rau qhov tseem ceeb ntawm cov hlau no.
