Deoxidation kev ua tau zoo ntawm silicon hlau hmoov
Hlau silicon hmoov, tseem hu ua coke, coke slag, coke block. Thaum cov thee raug rhaub mus rau ntau dua 850 ℃ nyob rau hauv lub tshuab ua kom sov sov, nrog rau qhov nce ntxiv ntawm qhov kub thiab txias, cov teeb meem organic hauv cov thee decomposes. Tom qab cov neeg ntwm tawm hauv cov khoom khiav dim, cov khoom lag luam uas tsis muaj neeg hloov dua tshiab yog coke. Qhov no suav nrog cov pa roj carbon ua hluav taws xob, uas hlawv, thiab cov hmoov tshauv, cov khoom seem ntawm kev hlawv. Nws hlawv nrog lub nplaim luv xiav heev thiab muaj hluav taws kub ntau. Cov txheej txheem sib txuas tawm yog qeeb thiab kav ntev, thiab nws yooj yim los ua cov khauj khaum saum npoo av. Coke feem ntau yog siv rau kev lag luam hlau, uas yog li ntawm 1/2 ~ 1/3 ntawm cov nqi tsim tawm ntawm cov hlau hlau.
Lub ntsiab lus tseem ceeb ntawm silicon hlau hmoov yog tsau cov, hloov pauv yog tsawg heev, thaum hlawv cov pa luam yeeb. Tus nqi ntsuas yog txog 25104 kJ / kg - 31380 kJ / kg. Silvery dawb lossis greyish dub, nws yog xim hlau luster, nyuaj thiab ntxeem tau. Cov block loj hu ua coke lossis metallurgical coke, cov me me hu ua tawg coke, hmoov hu ua coke chips. Ferroalloy ntau lawm nrog coke raws li txo tus neeg sawv cev, lub siab dua qhov ruaj khov ntawm cov pa roj carbon monoxide uas yuav tsum tau muaj, zoo dua, tsis tshua muaj tshauv, zoo dua. Lub particle loj muaj qhov cuam tshuam zoo ntawm kev zom. Cov loj hauv qhov loj me coke, dua li qhov tsis kam yog me me, hluav taws xob muaj zog, nyuaj hluav taws xob hluav taws xob, hluav taws xob cua sov ua kom sov ploj, loj coke cov tshuaj tiv thaiv saum npoo yog qhov me me, txo lub peev xwm raug txo kom tsawg, yog li cov coke loj rau hauv lub cub tawg yuav ua rau lub cub tawg zuj zus. Lub coke nrog cov me me qhov loj me, qhov kev tawm tsam yog loj, kev sib cuag yog loj, yuav ua rau cov electrode sib sib zog nqus, cov cua sov yuav tsawg dua, tab sis cov particle loj dua thiab yuav txo cov huab cua permeability ntawm lub txim, uas ua rau txoj kev sib tsoo hluav taws sib tsoo.
Yog li coke yuav tsum muaj qee qhov tsim nyog ntawm qhov me me. Qhov loj ntawm qhov loj me los cuam tshuam nrog lub peev xwm ntawm lub tshuab ua kom sov, lub coke particle qhov loj ntawm lub cub hluav taws xob loj dua, qhov coke particle qhov loj ntawm lub qhov cub hluav taws xob me dua. Nyob rau hauv cov txheej txheem ntawm cov smelting, cov ntsiab lus dej hauv coke yuav tsum tau kuaj xyuas tsis tu ncua thiab cov qauv ntawm lub cub tawg nqi yuav tsum raug kho kom ua rau lub cub tawg zoo li qub.
Hlau silicon hmoov yog ib qho ntawm cov khoom tseem ceeb ntawm peb lub tuam txhab. Cov hom hlau silicon hmoov muab los ntawm peb lub tuam txhab ua tiav, nrog kev ntseeg tau zoo thiab tus nqi tsim nyog, uas tuaj yeem ua tau raws li qhov xav tau ntawm cov neeg siv feem ntau rau cov hlau silicon hmoov. Txawm hais tias, tom qab ib lub sijhawm dhau los ntawm kev txhim kho, ntau thiab ntau tus neeg paub thiab nkag siab lub silicon hlau hmoov, silicon hlau hmoov kuj tseem nthuav dav daim ntawv thov tau ntawm, tab sis raws li kev ua haujlwm ntawm silicon hlau hmoov muaj ntau ntawm, txhua tus tsis muaj txhij txhua, thiab kev nkag siab ntawm silicon hlau hmoov nyob rau hauv qhov xwm txheej zoo li no, peb lub tuam txhab yuav tshab xyuas kev nkag siab ntawm silicon hlau hmoov ntau xyoo, ua kom luv luv ntawm silicon hlau hmoov hmoov kev ua tau zoo.
