Cov khoom siv raw siv hauv txoj kev oxygen tshuab decarburization yog cov pa roj carbon ntau ferromanganese. Txhawm rau tsim cov ferromanganese uas ua tau raws li tus qauv yuav tsum tau ua thiab ua tiav cov txiaj ntsig zoo thiab kev lag luam, tag nrho cov khoom siv raw yuav tsum ua kom tau raws li cov kev cai zoo.
Cov txheej txheem tseem ceeb ntawm ferromanganese muaj xws li electrosilicothermal txoj kev, co rauv txheej txheem ntau lawm, oxygen tshuab ntau lawm txoj kev, Bolan txoj kev thiab Udakan converter txoj kev. Cov khoom siv raw: Kev tsim cov khoom nruab nrab ntawm ferromanganese, uas yog raws li txoj kev electrosilicothermal thiab co rauv txoj kev, yuav tsum tau manganese-silicon alloy; cov kev cai rau manganese ore thiab ferromanganese ntau lawm yog siab manganese-hlau piv, tsawg phosphorus-manganese piv, thiab cov ntsiab lus silica tsawg; Txiv qaub thiab txiv qaub siv rau smelting ferromanganese xav tau cov ntsiab lus calcium oxide yuav tsum siab tshaj 85%, qhov loj me me nkag mus rau hauv lub cub tawg yuav tsum yog 10-60mm, thiab cov ntsiab lus me me ntawm cov ntsiab lus yuav tsum siab tshaj 80%.
Lub qhov cub induction rau kev tsim ferromanganese yog cov khoom siv cua sov induction nrog cov cua sov ua kom sov, ceev ceev, txuag hluav taws xob thiab kev tiv thaiv ib puag ncig rau cov ntaub ntawv hlau. High-frequency high-frequency tam sim no ntws mus rau lub cua sov coil qhov txhab rau hauv lub nplhaib lossis lwm yam duab. Yog li ntawd, thaum hlau thiab lwm yam khoom rhuab muab tso rau hauv lub kauj, ib tug muaj zog sib nqus beam uas ua instantaneous hloov nyob rau hauv polarity yuav nkag mus rau tag nrho cov khoom rhuab, tsim ib tug sib xws loj eddy tam sim no nyob rau hauv lub rhuab khoom nyob rau hauv lub opposite direction mus rau lub cua sov tam sim no. Vim yog qhov tsis kam ntawm cov khoom cua sov, qhov loj ntawm Joule cov cua sov yuav raug tsim, ua rau qhov kub ntawm cov khoom nws tus kheej nce siab, ua tiav lub hom phiaj ntawm cua sov tag nrho cov ntaub ntawv hlau.
Cov txheej txheem ntawm kev tsim cov pa roj carbon monoxide high-carbon ferromanganese siv lub qhov cub induction suav nrog cov kauj ruam hauv qab no: ntxiv cov khoom siv raw manganese-silicon alloy thiab manganese ore rau hauv qhov cub induction, energizing induction rauv, cua sov induction rauv, thiab melting manganese-silicon alloy. thiab manganese ore nyob rau hauv qhov cub induction; Tom qab melting, raws li induction Tus nqi ntawm manganese-silicon alloy thiab manganese ore nyob rau hauv lub cub hluav taws xob yog ntxiv rau induction hluav taws xob rauv, thiab cov alkalinity ntawm slag nyob rau hauv induction hluav taws xob rauv yog kho rau 1.4 ~ 1.6. Lub qhov cub hluav taws xob induction tseem ua kom sov thiab ua kom zoo, thiab lub zog ntawm qhov cub hluav taws xob induction yog 1500 ~ 6000kV; Tom qab ua kom tiav tiav, ncuav tawm lub slag rau ntawm qhov chaw; Tom qab dhau qhov kev kuaj sim, cov hlau nyob hauv qhov cub induction yog nchuav rau hauv cov khoom tiav.
Qhov kub ntawm qhov cub induction yog nruab nrab ntawm 1400 degree -1700 degree .
Induction hluav taws xob rauv yog cov khoom siv cua sov induction nrog cov cua sov ua kom sov, ceev ceev, txuag hluav taws xob thiab kev tiv thaiv ib puag ncig rau cov khoom siv hlau, uas txo cov nqi tsim khoom. Los ntawm kev kho thiab tswj lub zog lub sij hawm thiab lub zog, qhov kub thiab txias ua haujlwm tuaj yeem ua tiav rau kev hloov kho thiab tswj tau yooj yim. Induction furnaces hloov hluav taws xob hluav taws xob rau hauv thermal zog los ntawm electromagnetic induction rau cua sov, yaj thiab cov ntaub ntawv kub. Cov khoom tsim los ntawm cov khoom siv melted yog stirred zoo nyob rau hauv qhov kev txiav txim ntawm electromagnetic quab yuam, cov khoom melts sai sai, cov ntsiab lus alloy raug hlawv tsawg dua, thiab cov stirring muaj zog, uas yog tseem conducive rau deoxidation, degassing, thiab tshem tawm impurities. Cov khoom muaj purity siab, cov tshuaj muaj pes tsawg leeg yog yooj yim los kho thiab tswj, thiab muaj pes tsawg leeg muaj zoo uniformity.
Lub induction hluav taws xob rauv tsis ua kom cov pa roj carbon thiab sulfur thaum lub sij hawm smelting. Nws tuaj yeem npog cov hlau molten thaum cov txheej txheem smelting, uas tuaj yeem tiv thaiv oxidation ntawm silicon, manganese thiab alloy ntsiab nyob rau hauv cov hlau molten rau qee qhov, txo qhov nqus ntawm cov pa roj los ntawm lub cub tawg los ntawm cov hlau molten, thiab ua rau cov hlau. Cov kua yog purer, thiab qhov ntsuas kub tswj tau raug tswj qhov kub thiab txias, txhim kho qhov zoo thiab tsim nyog tus nqi ntawm high-carbon ferromanganese.
