Nrog rau kev hloov pauv tas mus li hauv kev lag luam kev lag luam ntawm cov ripples, DC melting rauv nrog nws qhov tshwj xeeb zoo thiab kev cia siab rau kev loj hlob, yog maj mam tshwm sim los ua lub hnub qub ci ntsa iab los ua kev lag luam kev lag luam.
Tam sim no nyob rau hauv metallurgical kev lag luam nyob rau hauv daim ntawv thov ntawm DC ntxhia tshav kub rauv yog txij li thaum 1970s pib tsim ib tug tshiab technology. DC furnace arc stabilization, lub zog concentration, siab thermal efficiency, nrog tsawg zog noj, tsawg electrode noj, tsis tshua muaj suab nrov, productivity siab.
Txawv teb chaws, xyoo 1984 hauv South Africa tau tsim muaj peev xwm 40MVA siab carbon ferrochrome direct tam sim no rauv. Tuam Tshoj 70-80 xyoo 1800-8000kvA ferrosilicon, muaj silicon, silicomanganese, ferrochrome, khoom khib nyiab kho DC ntxhia tshav kub rauv (ib qho hauv qab electrode) thiab DC steelmaking rauv tau ua tiav qee qhov kev paub dhau los, hauv xyoo tas los no, Tuam Tshoj tau tsim thiab muab tso rau hauv ntau lawm DC rauv yog feem ntau:
12500-33000kvA Silicon-Manganese DC Mineral Thaum tshav kub kub rauv (4 electrodes)
12500-16500kvA High Silicon DC Mineral Kub Rauv (4 electrodes)
12500kvA Silicon Barium DC Mineral Thaum tshav kub kub rauv (4 electrodes)
12500kvA Silicon Zirconium DC Mineral Thaum tshav kub kub rauv (4 electrodes)
10000-16000kw Muaj Silicon DC Mineral Thaum tshav kub kub rauv (4 electrodes)
9000kw Ferrochrome DC Mineral Thaum tshav kub kub rauv (4 electrodes)
30000kw Titanium Slag DC Mineral Kub Rauv (1 lub hauv paus electrode)
Txoj kev loj hlob ntawm DC melting furnaces sawv cev rau ib tug loj leap rau pem hauv ntej nyob rau hauv technological kev vam meej. Piv nrog rau cov tsoos AC ntxhia tshav kub rauv, nws qhov zoo yog pom tseeb. Nyob rau hauv cov nqe lus ntawm lub zog efficiency, DC melting rauv yuav hloov mus rau hauv tshav kub zog efficiency ho txhim kho. Cov ntaub ntawv tseeb qhia tau hais tias nws qhov kev siv hluav taws xob yog li 20% siab dua li cov tshuab hluav taws xob ib txwm siv, uas txo cov hluav taws xob poob zoo heev thiab ua rau lub zog muaj zog los txo cov nqi tsim khoom thiab txhim kho kev lag luam. Nyob rau tib lub sijhawm, DC ntxhia hluav taws kub rauv qhia tau zoo heev ruaj khov thiab tswj tau thaum lub sijhawm ua haujlwm, thiab muaj peev xwm tswj tau cov tshuaj tiv thaiv hauv lub cub tawg kom raug, yog li ua kom muaj kev txhim kho ruaj khov ntawm cov khoom zoo thiab kev tsim khoom ruaj khov.
Raws li cov ntaub ntawv uas twb muaj lawm, kev sib piv ntawm cov khoom ntsuas ntawm DC rauv thiab AC rauv, DC lub qhov cub tso zis, kev siv hluav taws xob thiab lwm yam ntsuas tau zoo dua li AC rauv, qhov nce hauv cov zis yog vim qhov txo qis ntawm smelting fais fab noj. thiab kev txhim kho lub zog ntawm qhov sib koom ua ke ntawm cov txiaj ntsig.
Tam sim no DC rauv 4 electrode, 6 electrodes thiab lwm yam kev siv tshuab hluav taws xob ntau, ntau qhov kev xav tau zoo ntawm DC ntxhia rauv hluav taws xob smelting ferroalloys, yog qhov sib txawv ntawm kev txuag hluav taws xob thiab cov khoom siv hluav taws xob loj. Tsis tas li ntawd, kev sib koom ua ke ntawm cov cuab yeej ntse ua rau DC smelting furnace automation degree zoo heev, kev ua haujlwm yooj yim dua thiab ua haujlwm tau zoo, rau kev tsim khoom lag luam tau coj kev yooj yim dua.
Nyob rau tib lub sijhawm raws li lub tswv yim ntawm kev tiv thaiv ib puag ncig hauv qhov tob, DC melting rauv kuj tseem ua haujlwm zoo rau cov qauv ntsuab ntawm lub sijhawm. Cov ntaub ntawv cuam tshuam qhia tau hais tias DC melting rauv nyob rau hauv lub zog txuag thiab emission txo kev ua tau zoo, cov pa phem emissions tau txo qis, rau kev txhim kho kom ruaj khov tau ua rau muaj zog.
Kev tshuaj xyuas keeb kwm kev txhim kho ntawm DC melting rauv, peb tsis tuaj yeem pab tab sis xav tsis thoob ntawm kev ua haujlwm nyuaj thiab kev txawj ntse ntawm cov kws tshawb fawb thiab cov kws tsim khoom. Los ntawm cov kab mob ntawm thawj lub tswv yim, mus rau kev txhim kho txuas ntxiv thiab kev ua kom zoo ntawm kev siv tshuab, txhua kauj ruam ntawm lawv hws thiab kev txawj ntse. Piv txwv li, thaum tsim lub DC melting rauv, ib lub lag luam tau ua tiav qhov zoo ntawm cov hluav taws xob tsis zoo thiab cov khoom siv hluav taws xob thiab cov qauv tom qab ntau qhov kev sim thiab kev txhim kho, kom lub cev lub cev muaj zog tuaj yeem tiv taus huab cua zoo xws li qhov kub thiab txias, thiab ntawm qhov tib lub sijhawm, kev ua haujlwm ntawm cov electrodes thiab lwm yam tseem ceeb kuj tau txhim kho zoo heev.
Saib tom ntej, DC ntxhia hluav taws xob cua sov yuav tsum ua kom tiav ntau dua thiab kev txhim kho:
Ua ntej tshaj plaws, kev tsim kho thev naus laus zis yuav txhawb nqa lub zog ua haujlwm thiab ruaj khov ntawm DC melting rauv kom txhim kho ntxiv, pab cov lag luam kom txo cov nqi tsim khoom thiab txhim kho kev lag luam kev sib tw.
Qhov thib ob, kev txhim kho ntawm DC ntxhia cua sov rauv yuav ua kom zoo dua ntawm kev txawj ntse, cov ntaub ntawv loj thiab lwm yam kev txawj ntse txhais tau tias kom paub txog lub sijhawm saib xyuas thiab kev tswj tsis siv neeg ntawm lub qhov cub tawg, ua kom nrawm rau daim ntawv thov cov cuab yeej ntse ntse, suav nrog AI ntse. refining, qhib plug qhov muag neeg hlau, txuas electrode neeg hlau, tsis siv neeg pounding tshuab, tshuaj xyuas neeg hlau, kub imaging ntaus ntawv nyob rau hauv lub cub tawg, tsis siv neeg clearing ntaus ntawv, nruam casting system, thiab lwm yam advanced auxiliary khoom daim ntawv thov, nyob rau hauv thiaj li yuav txhim kho ntau lawm efficiency, txo lub zog. noj, txhim kho cov khoom zoo, thiab paub txog kev txawj ntse thiab ntsuab ntawm kev tsim khoom.
Tsis tas li ntawd, daim ntawv thov kev lag luam ntawm DC melting rauv yuav nthuav dav ntxiv, ntxiv rau kev ua lub luag haujlwm tseem ceeb hauv kev lag luam metallurgical, nws yuav tsum tau siv dav hauv kev lag luam tshuaj, cov khoom siv thiab lwm yam kev lag luam, pab txhawb kev loj hlob thiab kev loj hlob. ntawm ntau kev lag luam.
Kev ua tiav ntawm DC hauv cov hluav taws xob hluav taws xob hluav taws xob tau coj cov txiaj ntsig tseem ceeb thiab txoj hauv kev txhim kho rau kev lag luam smelting. Los ntawm kev nruam ntej thiab kev ua haujlwm thev naus laus zis, peb muaj laj thawj ntseeg tias DC yuav ua lub luag haujlwm tseem ceeb hauv lub neej yav tom ntej, los txhawb kev txhim kho txuas ntxiv thiab kev vam meej ntawm cov tshuab hluav taws xob hluav taws xob hluav taws xob, smelting thev naus laus zis los txhim kho thiab muab qhov chaw tsis txwv rau kev txhim kho. ntawm cov khoom tshiab, rau kev lag luam teb kom coj tau qhov kev pom dav dav thiab kev txhim kho nyob rau yav tom ntej.
Nyob rau hauv luv luv, DC ntxhia tshav kub rauv nrog nws tshwj xeeb zoo thiab dav prospects rau txoj kev loj hlob, yuav mus txuas ntxiv mus ua lub luag hauj lwm tseem ceeb nyob rau hauv lub neej yav tom ntej kev lag luam teb, thiab ua kom muaj kev koom tes ntau dua rau kev vam meej ntawm kev lag luam thiab kev loj hlob. Peb tab tom nrhiav rau pem hauv ntej rau ntau qhov kev tsim kho tshiab thiab kev ua tiav los txhawb DC ntxhia hluav taws xob cua sov tshuab rau lub ncov tshiab!
