Ob peb hnub dhau los, xov xwm zoo tau muab tso tawm los ntawm lub rooj sib tham txog kev tshawb fawb thiab thev naus laus zis ntawm "Key Technology Research thiab Industrial Application of Refractory Iron Oxide Ore Suspension Magnetization Roasting" hosted los ntawm Gansu Institute of Metals: Tag nrho cov thev naus laus zis ntawm kev tshawb fawb thiab technologies achievements tau mus txog lub thoob ntiaj teb ua theem, thiab nws yog pom zoo kom ua kom lub nce qib thiab daim ntawv thov.
Tus thawj ore ntawm Jingtieshan Mine ntawm JISCO muaj qib hlau tsis tshua muaj, ntau hom hlau-cov kabmob, kev sib raug zoo symbiosis thiab siab impurity cov ntsiab lus.Nws belongs rau cov txheej txheem refractory hlau oxide ore hauv Suav teb.Cov txheej txheem kev noj qab haus huv ib txwm muaj cov hlau rov qab qis thiab tsis zoo ntawm kev mloog zoo., Uas cuam tshuam rau cov txiaj ntsig kev lag luam ntawm kev lag luam, thiab tsis tuaj yeem ua tau raws li qhov xav tau ntawm Jiuquan Steel rau kev txhim kho zoo thiab kev ua haujlwm zoo, kev hloov pauv thiab kev txhim kho, thiab kev txhim kho zoo.
Txhawm rau txhim kho kev ua tau zoo ntawm kev siv cov peev txheej, Jiugang Group tau koom tes nrog Northeastern University, Shenyang Xinbo Industrial Technology Co., Ltd. thiab lwm lub koom haum los koom ua ke tsim kev ncua kev sib nqus hlau nplaum roasting thev naus laus zis rau refractory hlau oxide ore, thiab nqis peev hauv kev tsim kho. kev ncua nrog kev ua haujlwm txhua xyoo ntawm 1.65 lab tons ntawm cov ore raw.Cov kab hlau nplaum roasting thiab tau txais txiaj ntsig ntau lawm tau muab tso rau hauv kev ua haujlwm thaum Lub Kaum Ib Hlis 21, 2020, thiab tau ua tiav tag nrho cov khoom tsim thiab ua raws li lub Rau Hli 25 xyoo no.Piv nrog rau thawj cov txheej txheem sib nqus sib nqus, cov qib hlau ntawm cov concentrate yog nce 12%, thiab cov hlau rov qab tau nce 26%.Cov nyhuv tseem ceeb heev.
Ntawm lub rooj sib tham kev ntsuam xyuas, xya tus kws tshaj lij suav nrog Sun Chuanyao, tus kws tshaj lij ntawm Suav Academy ntawm Engineering, tau mloog cov lus ceeb toom, tshuaj xyuas cov ntaub ntawv, thiab sib tham txog cov lus nug, tsom mus rau qib ntawm kev tsim kho thev naus laus zis, qib siab ntawm kev ntsuas thiab kev lag luam, kev nyuaj siab thiab complexity, technical reproducibility and maturity, Technological innovation tau ua tib zoo soj ntsuam cov txiaj ntsig ntawm rau qhov, suav nrog lub luag haujlwm ntawm kev txhawb nqa kev lag luam thev naus laus zis thiab kev txhim kho kev lag luam kev sib tw, kev lag luam lossis kev sib raug zoo, thiab cov kev ntsuam xyuas zaum kawg tau tsim.Cov kws tshuaj ntsuam xyuas ntseeg tau hais tias cov kev tshawb fawb thiab thev naus laus zis ua tiav los ntawm Jiuquan Steel Group thiab lwm cov chav nyob muaj kev hloov kho thev naus laus zis siab.Thawj qhov raug tshem tawm hauv tsev thiab txawv teb chaws magnetized roasting thiab beneficiation ntau lawm kab nrog kev ua txhua xyoo ntawm 1.65 lab tons ntawm cov nplua ore muaj cov cuab yeej zoo tshaj plaws thiab daws qhov nyuaj thiab nyuaj rau hnav hlau ore.Qhov teeb meem ntawm kev siv tau zoo ntawm cov peev txheej tau txhawb nqa kev lag luam zoo ntawm kev lag luam hlau ore beneficiation.Nyob rau hauv kev pom ntawm cov teeb meem ntawm cov ore ntawm Jiuquan Hlau thiab hlau, Jiuquan Iron thiab Steel Group thiab lwm yam kev ua tiav qhov project tau nquag tshawb nrhiav thiab xyaum, daws cov teeb meem kev lag luam hauv kev lag luam ntawm kev ncua kev sib nqus magnetization roasting tshuab, thiab ua tiav kev ua haujlwm ruaj khov thiab tag nrho cov txheej txheem tau mus txog cov qauv tsim khoom.Tag nrho cov txheej txheem thev naus laus zis yog qhov nyuaj thiab nyuaj.Txog rau tam sim no, cov kab ntau lawm tau ua haujlwm ruaj khov rau ib xyoos, nrog cov thev naus laus zis siab loj thiab rov ua dua tshiab, uas muab kev txhawb nqa rau kev daws teeb meem zoo ntawm kev siv cov khoom siv refractory hlau oxide ore, thiab txhim kho cov kev sib tw tseem ceeb ntawm kev lag luam. .Cov pa hluav taws xob tawm mus txog Gansu Provincial industrial furnaces xav tau kev kho mob tob, uas muaj txiaj ntsig tseem ceeb ntawm kev lag luam, kev sib raug zoo thiab ib puag ncig.
Nws tau nkag siab tias thaum lub sijhawm "14th Tsib Xyoo Plan", Jiu Steel Group yuav, raws li nws tus kheej cov peev txheej zoo thiab cov yam ntxwv ntawm cov peev txheej ib puag ncig, ntxiv txhawb cov tswv yim tshiab-tsav cov tswv yim thiab cov tswv yim kev lav phib xaub, txhawb nqa daim ntawv thov ncua kev sib nqus magnetization. roasting thev naus laus zis, thiab tsim kom muaj txiaj ntsig zoo, ruaj khov thiab muaj ntau hom hlau Cov pob zeb hauv av lav qhov system muab kev txhawb nqa rau cov lag luam kom sib koom ua ke lawv lub hauv paus kev lag luam, hloov kho lawv cov txiaj ntsig kev sib tw, thiab tuav txoj kev loj hlob hauv av.
