Nrog rau kev hloov pauv tas mus li hauv kev lag luam ntawm cov ripples, DC melting furnace nrog nws cov txiaj ntsig tshwj xeeb thiab kev cia siab dav dav rau kev txhim kho, maj mam tshwm sim ua lub hnub qub ci ntsa iab los coj kev lag luam kev nce qib hauv kev siv tshuab.
Tam sim no hauv kev lag luam metallurgical hauv daim ntawv thov DC cua sov pob zeb yog txij li xyoo 1970 pib tsim cov thev naus laus zis tshiab. DC cua sov arc stabilization, lub zog concentration, thermal efficiency siab, nrog rau kev siv hluav taws xob tsawg, kev siv hluav taws xob tsawg dua, suab nrov ua haujlwm tsawg, kev tsim khoom siab.
Nyob rau txawv teb chaws, xyoo 1984 hauv South Africa tau tsim lub cub tawg tam sim no 40MVA uas muaj cov pa roj carbon siab ferrochrome. Tuam Tshoj tau tsim 1800-8000kvA ferrosilicon, industrial silicon, silicomanganese, ferrochrome, thiab cov khoom pov tseg kho DC cua sov (ib qho electrode hauv qab) thiab DC steelmaking cub tawg tau ua tiav qee qhov kev paub zoo, nyob rau xyoo tas los no, Tuam Tshoj tau tsim thiab muab tso rau hauv kev tsim khoom DC cub tawg yog:
12500-33000kvA Silicon-Manganese DC Mineral Kub Rauv (4 electrodes)
12500-16500kvA High Silicon DC Mineral Kub Rauv (4 electrodes)
12500kvA Silicon Barium DC Cov Khoom Siv Hluav Taws Xob Kub (4 lub electrodes)
12500kvA Silicon Zirconium DC Cov Khoom Siv Hluav Taws Xob Kub (4 lub electrodes)
10000-16000kw Industrial Silicon DC Mineral Kub Rauv (4 electrodes)
9000kw Ferrochrome DC Cov Khoom Siv Hluav Taws Xob Kub (4 lub electrodes)
30000kw Titanium Slag DC Cov Khoom Siv Hluav Taws Xob Kub (1 lub hauv paus electrode)
Kev tsim cov DC melting furnaces sawv cev rau qhov kev dhia loj hauv kev nce qib hauv kev siv tshuab. Piv nrog rau cov AC mineral heat furnaces ib txwm muaj, nws cov txiaj ntsig yog qhov pom tseeb. Hais txog kev siv hluav taws xob zoo, DC melting furnaces yuav raug hloov mus ua thermal energy efficiency zoo dua. Cov ntaub ntawv tseeb qhia tau tias nws cov nqi siv hluav taws xob yog li 20% siab dua li cov furnaces ib txwm muaj, uas txo qis kev poob hluav taws xob thiab txhaj tshuaj muaj zog los txo cov nqi tsim khoom thiab txhim kho kev lag luam zoo. Tib lub sijhawm, DC mineral heat furnaces qhia tau tias muaj kev ruaj khov zoo thiab kev tswj hwm thaum lub sijhawm ua haujlwm, thiab muaj peev xwm tswj tau qhov xwm txheej ntawm cov tshuaj tiv thaiv hauv lub cub tawg, yog li ua kom ntseeg tau tias muaj kev txhim kho zoo ntawm cov khoom zoo thiab kev nce ntxiv ntawm cov khoom.
Raws li cov ntaub ntawv uas twb muaj lawm, kev sib piv tag nrho ntawm cov ntsuas kev tsim khoom ntawm DC cub tawg thiab AC cub tawg, DC cub tawg tso zis, kev siv hluav taws xob thiab lwm yam ntsuas tau zoo dua li AC cub tawg, qhov nce ntxiv ntawm cov zis yog vim qhov txo qis ntawm kev siv hluav taws xob smelting thiab kev txhim kho ntawm lub zog fais fab ntawm cov txiaj ntsig sib koom ua ke.
Tam sim no DC lub cub tawg 4 electrode, 6 electrodes thiab lwm yam kev tsim kho thev naus laus zis ntau-electrode, ntau dua qhov cuam tshuam qhov zoo ntawm DC lub cub tawg mineral smelting ferroalloys, yog qhov tsis zam ntawm kev txuag hluav taws xob thiab lub cub tawg mineral loj. Tsis tas li ntawd, kev koom ua ke ntawm cov thev naus laus zis ntse ua rau DC smelting lub cub tawg automation degree zoo dua, kev ua haujlwm yooj yim dua thiab ua haujlwm tau zoo, rau kev tsim khoom lag luam tau coj kev yooj yim heev.
Tib lub sijhawm uas lub tswv yim ntawm kev tiv thaiv ib puag ncig tob tob, DC melting furnace kuj tseem niaj hnub txais tos qhov sib txawv ntsuab ntawm lub sijhawm. Cov ntaub ntawv cuam tshuam qhia tau tias DC melting furnace hauv kev txuag hluav taws xob thiab kev txo qis kev ua haujlwm zoo heev, cov pa phem tau raug txo qis, rau kev txhim kho ruaj khov tau pab txhawb rau lub zog.
Los ntawm kev tshuaj xyuas keeb kwm kev loj hlob ntawm DC melting furnace, peb tsis tuaj yeem pab tab sis xav tsis thoob rau kev ua haujlwm nyuaj thiab kev txawj ntse ntawm cov kws tshawb fawb thiab cov engineers. Txij li thaum pib ntawm lub tswv yim, mus rau kev txhim kho tas mus li thiab kev ua kom zoo dua ntawm thev naus laus zis, txhua kauj ruam ntawm lawv cov hws thiab kev txawj ntse. Piv txwv li, thaum tsim DC melting furnace, ib lub tuam txhab tau ua tiav qhov kev ua kom zoo dua ntawm cov khoom siv hluav taws xob thiab cov khoom siv hauv lub cub tawg thiab cov qauv tom qab ntau qhov kev sim thiab kev txhim kho, yog li lub cev cub tawg tuaj yeem tiv taus cov xwm txheej hnyav xws li kub thiab siab, thiab tib lub sijhawm, kev ua tau zoo ntawm cov electrodes thiab lwm yam khoom tseem ceeb kuj tau txhim kho zoo heev.
Saib mus tom ntej, DC lub cub tawg cua sov yuav tsum ua tiav kev tshawb pom thiab kev txhim kho ntau dua:
Ua ntej tshaj plaws, kev tsim kho tshiab hauv kev siv tshuab yuav txhawb nqa kev siv hluav taws xob thiab kev ruaj khov ntawm DC melting furnace kom txhim kho ntxiv, pab cov tuam txhab kom txo cov nqi tsim khoom thiab txhim kho kev sib tw ua lag luam.
Qhov thib ob, kev tsim cov cua sov DC hauv av yuav siv qhov zoo ntawm kev txawj ntse, cov ntaub ntawv loj thiab lwm yam thev naus laus zis ntse los paub txog kev saib xyuas lub sijhawm tiag tiag thiab kev tswj hwm tsis siv neeg ntawm cov xwm txheej ntawm lub cub tawg, ua kom nrawm dua kev siv cov khoom siv pabcuam ntse, suav nrog AI ntse refining, qhib lub qhov muag neeg hlau, txuas electrode neeg hlau, tshuab ntaus tsis siv neeg, neeg hlau tshuaj xyuas, cov cuab yeej ntsuas kub siab hauv lub cub tawg, cov cuab yeej tshem tawm tsis siv neeg, lub kaw lus casting tas mus li, thiab lwm yam khoom siv pabcuam siab heev, txhawm rau txhim kho kev ua haujlwm ntau lawm, txo kev siv hluav taws xob, txhim kho cov khoom zoo, thiab paub txog kev txawj ntse thiab ntsuab ntawm lub kaw lus ntau lawm.
Tsis tas li ntawd xwb, cov teb thov ntawm DC melting furnace kuj tseem yuav nthuav dav, ntxiv rau kev ua lub luag haujlwm tseem ceeb hauv kev lag luam metallurgical, nws xav tias yuav siv dav hauv kev lag luam tshuaj lom neeg, cov ntaub ntawv thiab lwm yam teb, pab txhawb rau kev nce qib thiab kev txhim kho ntawm ntau yam kev lag luam.
Kev siv DC zoo hauv cov cua sov ua los ntawm cov pob zeb tau coj cov txiaj ntsig zoo thiab kev txhim kho rau kev lag luam smelting. Los ntawm kev tsim kho tshiab tas mus li thiab kev nce qib ntawm thev naus laus zis, peb muaj laj thawj ntseeg tias DC yuav txuas ntxiv ua lub luag haujlwm tseem ceeb yav tom ntej, los txhawb kev txhim kho tas mus li thiab kev nce qib ntawm cov thev naus laus zis cua sov ua los ntawm cov pob zeb, kev siv tshuab smelting los txhim kho thiab muab qhov chaw tsis muaj kev txwv rau kev tsim cov khoom tshiab, rau kev lag luam kom coj kev pom dav dua thiab kev txhim kho ruaj khov ntawm yav tom ntej.
Hauv ntej, DC lub cub tawg cua sov nrog nws cov txiaj ntsig tshwj xeeb thiab kev cia siab dav dav rau kev txhim kho, yuav txuas ntxiv ua lub luag haujlwm tseem ceeb hauv kev lag luam yav tom ntej, thiab ua rau muaj kev pab ntau dua rau kev nce qib ntawm kev lag luam thiab kev txhim kho ruaj khov. Peb tab tom tos ntsoov rau ntau qhov kev tsim kho tshiab thiab kev tawg ua kom txhawb nqa DC lub cub tawg cua sov thev naus laus zis mus rau qhov siab tshaj plaws tshiab!
