Ob peb hnub dhau los, cov xov xwm zoo tau tshaj tawm los ntawm lub rooj sib tham txog kev ntsuam xyuas kev ua tiav ntawm kev tshawb fawb thiab thev naus laus zis ntawm "Kev Tshawb Fawb Txog Kev Siv Tshuab Tseem Ceeb thiab Kev Siv Khoom Siv Refractory Iron Oxide Ore Suspension Magnetization Roasting" uas tau tuav los ntawm Gansu Institute of Metals: Tag nrho cov thev naus laus zis ntawm kev ua tiav ntawm kev tshawb fawb thiab thev naus laus zis tau mus txog qib thoob ntiaj teb, thiab nws raug pom zoo kom ua kom nrawm dua kev txhawb nqa thiab daim ntawv thov.

Cov hlau qub ntawm Jingtieshan Mine ntawm JISCO muaj cov hlau qis, ntau hom hlau uas muaj hlau, kev sib raug zoo ntawm cov hlau thiab cov khoom tsis huv. Nws yog cov hlau refractory hlau oxide uas nyuaj rau refractory hauv Suav teb. Cov txheej txheem kev pabcuam ib txwm muaj cov hlau rov qab tau qis thiab cov khoom tsis zoo. , Uas cuam tshuam rau cov txiaj ntsig kev lag luam ntawm cov tuam txhab, thiab tsis tuaj yeem ua tau raws li qhov xav tau ntawm Jiuquan Steel rau kev txhim kho qhov zoo thiab kev ua haujlwm zoo, kev hloov pauv thiab kev txhim kho, thiab kev txhim kho zoo.

Yuav kom txhim kho kev siv cov peev txheej tau zoo, Jiugang Group tau koom tes nrog Northeastern University, Shenyang Xinbo Industrial Technology Co., Ltd. thiab lwm lub chaw ua haujlwm los tsim cov thev naus laus zis magnetization roasting rau cov hlau oxide refractory, thiab nqis peev rau kev tsim cov khoom siv nrog lub peev xwm ua tiav txhua xyoo ntawm 1.65 lab tons ntawm cov hlau nyoos. Cov kab ntau lawm magnetized roasting thiab beneficiation tau muab tso rau hauv kev ua haujlwm rau lub Kaum Ib Hlis 21, 2020, thiab ua tiav tag nrho cov khoom tsim tawm thiab ua raws li txoj cai rau lub Rau Hli 25 xyoo no. Piv nrog rau cov txheej txheem sib cais magnetic muaj zog thawj zaug, qib hlau ntawm cov concentrate tau nce 12%, thiab tus nqi rov qab hlau tau nce 26%. Qhov cuam tshuam yog qhov tseem ceeb heev.

Ntawm lub rooj sib tham ntsuam xyuas, xya tus kws tshaj lij suav nrog Sun Chuanyao, tus kws tshawb fawb ntawm Suav Academy of Engineering, tau mloog cov ntawv ceeb toom, tshuaj xyuas cov ntaub ntawv, thiab tham txog cov lus nug, tsom mus rau qib ntawm kev tsim kho tshiab, qib siab ntawm cov cim qhia txog kev lag luam thiab kev lag luam, qhov nyuaj thiab qhov nyuaj ntawm kev siv tshuab, kev tsim kho dua tshiab thiab kev loj hlob, kev tsim kho tshiab tau soj ntsuam cov txiaj ntsig hauv rau yam, suav nrog lub luag haujlwm ntawm kev txhawb nqa kev lag luam kev lag luam thiab kev txhim kho kev sib tw ua lag luam, kev lag luam lossis kev sib raug zoo, thiab cov kev xav ntsuam xyuas zaum kawg tau tsim. Cov kws tshaj lij ntsuam xyuas ntseeg tias cov kev ua tiav ntawm kev tshawb fawb thiab kev siv tshuab uas Jiuquan Steel Group thiab lwm chav tsev ua tiav muaj qib siab ntawm kev tsim kho tshiab. Thawj kab tsim khoom hauv tsev thiab txawv teb chaws uas muaj magnetized roasting thiab beneficiation nrog kev ua tiav txhua xyoo ntawm 1.65 lab tons ntawm cov hlau zoo tau ua tiav cov cim qhia txog kev siv tshuab thiab daws cov hlau nyuaj thiab nyuaj rau hnav. Qhov teeb meem ntawm kev siv cov peev txheej zoo tau txhawb nqa kev nce qib ntawm kev lag luam hlau ore beneficiation. Vim muaj teeb meem ntawm cov hlau thiab hlau ntawm Jiuquan, Jiuquan Iron thiab Steel Group thiab lwm cov chaw ua tiav qhov project tau tshawb nrhiav thiab xyaum ua, daws ntau yam teeb meem kev siv tshuab hauv kev siv tshuab magnetization roasting, 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 Cov thev naus laus zis nyuaj thiab nyuaj. Txog tam sim no, cov kab ntau lawm tau ua haujlwm ruaj khov rau ib xyoos, nrog kev paub txog thev naus laus zis siab thiab kev ua tiav rov ua dua, uas muab kev txhawb nqa kev siv tshuab rau kev daws teeb meem ntawm kev siv cov khoom siv hlau oxide refractory zoo, thiab txhim kho kev sib tw tseem ceeb ntawm lub tuam txhab. Cov pa roj flue mus txog Gansu Provincial industrial furnaces xav tau kev kho mob tob, uas muaj txiaj ntsig zoo rau kev lag luam, kev sib raug zoo thiab ib puag ncig.

Nws nkag siab tias thaum lub sijhawm "14th Tsib-Xyoo Txoj Kev Npaj", Jiu Steel Group yuav, raws li nws cov txiaj ntsig ntawm cov peev txheej thiab cov yam ntxwv ntawm cov peev txheej ib puag ncig, txhawb nqa ntxiv cov tswv yim tsim kho tshiab thiab cov tswv yim lav cov peev txheej, txhawb kev siv cov thev naus laus zis magnetization roasting, thiab tsim kom muaj hlau zoo, ruaj khov thiab ntau yam. Lub kaw lus lav cov peev txheej hauv av muab kev txhawb nqa zoo rau cov tuam txhab kom sib sau ua ke lawv lub hauv paus kev lag luam, rov tsim kho lawv cov txiaj ntsig sib tw, thiab txeeb tau qhov chaw siab ntawm kev txhim kho.
