Khoom Description
Rau cov me me silicon ore (particle loj<20mm) produced in the production process of 70 ferrosiliconthiab muaj silicon, nws yog thawj zaug cais raws li particle loj. Thaum qhov loj me me ntawm silicon ore yog qis dua 5, nws tuaj yeem siv ncaj qha los ua raw khoom rau smelting hauv txoj kev no; Thaum cov particle loj me me nyob nruab nrab ntawm 5-20mm, nws yuav tsum tau crushed mus rau ib tug particle loj hauv qab no 5 hli ua ntej nws yuav siv tau raws li raw khoom rau smelting nyob rau hauv txoj kev no.
Tshuab tshuab thiab slagging txheej txheem
Hauv cov txheej txheem tsim khoom ntawm 70 silicon ferroalloy, kev ua kom zoo sab nraud yog ib kauj ruam tseem ceeb, uas ua lub luag haujlwm tseem ceeb hauv kev txhim kho cov khoom zoo. Cov txheej txheem tshuab yog ib qho tseem ceeb, uas yuav tsum tau tshuab ib qho kev sib xyaw ntawm cov pa roj rau hauv 70 silicon hlau alloy yaj kom tshem tawm impurities. Koj tuaj yeem xaiv qhov sib xyaw ntawm ib lossis ob peb lub gases nyob rau hauv ib qho kev faib ua feem, nrog rau cov pa oxygen, oxygen, thiab chlorine. Lub tshuab tshuab yog nruab nrab ntawm 2 thiab 8 atm, tus nqi ntws yog 0.1 txog 1 hm3 / min, thiab lub sijhawm yog 0.5 txog 5 teev. Lub tshuab tshuab no tuaj yeem tshem tawm ntau yam hlau lossis tsis yog hlau tsis huv xws li Al, Ca, C, S, Ti, P, Mn, Cr, Mg, Cu, V, Ni, thiab lwm yam los ntawm silicon hlau alloys. Piv txwv li, thaum muaj cov tshuaj chlorine uas tsim nyog tau tawg rau hauv, nws tuaj yeem hnov mob nrog qee yam impurities, hloov lawv mus rau hauv cov khoom sib cais yooj yim.
Txoj kev ua slag yog sib npaug indispensable. Ntxiv ib qho nyiaj ntawm hluavtaws slag rau 70 silicon hlau alloy yaj, uas suav nrog ib lossis ob peb yam xws li quicklime, quartz xuab zeb, fluorite, hlau phosphorus, thiab alkali hlau oxides. Qhov sib ntxiv yog 5% mus rau 25% ntawm cov yaj ntawm 70 silicon hlau alloy, thiab lub sijhawm ntev yog 0.5 mus rau 5 teev. Los ntawm txoj kev no, nws tseem tuaj yeem xaiv tshem tawm cov impurity ntsiab. Piv txwv li, quicklime tuaj yeem tsim cov tebchaw ruaj khov nrog qee qhov impurities, yog li ua tiav qhov kev sib cais ntawm impurities.
Nws yog ib nqi sau cia hais tias cov saum toj no-hais tshuab refining txheej txheem thiab slag refining txheej txheem yuav nqa tawm nyias los yog ib txhij, thiab cov kev xaiv tshwj xeeb nyob ntawm qhov tseeb ntau lawm thiab cov khoom yuav tsum tau.
