Taw qhia rau cov txheej txheem ntau lawm ntawm ferrosilicon
Ferrosilicon, tseem hu ua FeSi, yog ib qho tseem ceeb alloy dav siv hauv steelmaking ntau lawm. Cov hlau no tuaj yeem muab cov hlau xav tau, suav nrog kev ua kom tawv tawv, tensile zog thiab corrosion kuj. Nws kuj tseem siv rau hauv kev tsim cov hlau cam khwb cia, cov khoom siv hluav taws xob tsim khoom thiab cov khoom siv silicon, thiab lwm yam.
Cov ntaub ntawv tseem ceeb rau kev tsim cov ferrosilicon yog silica xuab zeb thiab coke, nrog rau cov ntaub ntawv hlau. Thawj kauj ruam hauv cov txheej txheem yog txhawm rau txhawm rau cov khoom siv raw rau hauv cov khoom me me. Cov silica xuab zeb yog rhuab mus txog 2,200℃F kom tshem tawm cov dej los yog impurities thiab xyuas kom meej tias nws yog nyob rau hauv ib daim ntawv haum rau ntau lawm. Tom qab ntawd cov silica xuab zeb rhuab yog tov nrog coke thiab hlau filings los tsim ib tug sib tov hu ua nqi.
Tom qab ntawd tus nqi yog nkag mus rau hauv lub cub hluav taws xob hluav taws xob thiab preheated txog 2,000℃F kom ntseeg tau tias cov khoom nyob rau hauv txoj cai rau cov txheej txheem tshuaj tiv thaiv. Lub tshuab hluav taws xob arc rauv yog ib lub thawv loj insulated tsim los ua kom muaj cua sov los ntawm hluav taws xob. Nyob rau hauv lub qhov cub, tus nqi yog melted, ib tug tshuaj tiv thaiv tshwm sim, thiab cov coke txo cov silica rau silicon thiab carbon monoxide gas. Cov ntaub ntawv hlau kuj tseem oxidized, thiab silicon thiab hlau ua ke los ua ferrosilicon.
