Hauv kev lag luam steel, kev siv cov hmoov ferrosilicon ntawm qhov kub thiab txias tuaj yeem tso tawm ntau cov cua sov no, feem ntau yog siv los ua tus neeg sawv cev ntawm cov cua sov los txhim kho qhov zoo ntawm steel ingots thiab tus nqi rov qab.
(2) Siv los ua inoculant thiab spheroidising tus neeg sawv cev hauv kev lag luam cam khwb cia hlau. cam khwb cia hlau yog cov khoom siv hlau tseem ceeb hauv kev lag luam niaj hnub no, nws yog pheej yig dua li cov hlau, yooj yim rau yaj smelting, nrog kev ua haujlwm zoo tshaj plaws thiab zoo dua li steel seismic peev. Tshwj xeeb tshaj yog ductile cam khwb cia hlau, nws cov khoom siv kho tshuab ncav cuag lossis ze rau cov khoom siv ntawm cov hlau. Ntxiv ib qho nyiaj ntawm ferrosilicon hauv cam khwb cia hlau tuaj yeem tiv thaiv kev tsim cov carbides hauv hlau, txhawb cov nag lossis daus ntawm graphite thiab spheroidisation, thiab yog li hauv kev tsim cov hlau, ferrosilicon yog ib qho tseem ceeb inoculant (los pab precipitate graphite) thiab spheroidising tus neeg sawv cev.
(3) Siv los txo tus neeg sawv cev hauv ferroalloy ntau lawm. Tsis tsuas yog muaj cov tshuaj lom neeg zoo ntawm silicon thiab oxygen, tab sis siab silica ferrosilicon muaj cov ntsiab lus qis heev. Yog li ntawd, siab silica ferrosilicon (los yog siliceous alloy) yog ib hom kev txo tus neeg sawv cev uas feem ntau siv los tsim cov pa roj carbon tsawg hauv kev lag luam ferroalloy.
(4) 75 # Ferrosilicon nyob rau hauv Pijiang txoj kev ntawm refining magnesium feem ntau yog siv nyob rau hauv lub kub kub smelting txheej txheem ntawm magnesium hlau los hloov cov magnesium nyob rau hauv CaO.MgO, thiab txhua tonnes ntawm magnesium hlau yuav tsum tau siv yuav siv li 1.2 tonnes ntawm ferrosilicon, uas plays lub luag haujlwm zoo hauv kev tsim cov hlau magnesium.
(5) Siv rau lwm yam. Sib tsoo zoo los yog atomisation ua tiav ferrosilicon hmoov, nyob rau hauv cov ntxhia ua kev lag luam yuav siv tau raws li ib tug ncua kev kawm ntawv theem. Nws tuaj yeem siv los ua txheej rau vuam rods hauv kev lag luam vuam pas nrig. High-silicon ferrosilicon tuaj yeem siv rau hauv kev lag luam tshuaj los tsim cov khoom xws li silicone.
