Ferrosilicon yog dav siv nyob rau hauv steelmaking kev lag luam raws li ib tug deoxidizer thiab alloying neeg sawv cev. Nws lub luag haujlwm tseem ceeb yog tshem tawm cov pa oxygen los ntawm cov hlau thaum lub sijhawm kawg ntawm cov hlau tsim, kom ntseeg tau cov tshuaj lom neeg uas xav tau thiab tag nrho cov khoom zoo. Silicon muaj cov tshuaj lom neeg muaj zog nrog cov pa oxygen, ua rau ferrosilicon muaj txiaj ntsig zoo deoxidizer los ntawm nag lossis daus thiab diffusion. Ntxiv mus, qhov sib ntxiv ntawm silicon rau hlau txhim kho nws lub zog, hardness, thiab elasticity.
Ferrosilicon kuj tseem siv los ua tus neeg sawv cev alloying hauv qee cov ntawv thov steel. Piv txwv li, nws tau suav nrog hauv kev tsim cov hlau hluav taws xob rau cov khoom siv hluav taws xob, qhov twg cov ntsiab lus silicon nyob ntawm 2.81% mus rau 4.8%. Tsis tas li ntawd, ferrosilicon plays lub luag haujlwm tseem ceeb hauv kev txhim kho kev suav nrog thiab txo cov khoom siv roj hauv cov hlau molten. Cov thev naus laus zis tshiab no txhim kho cov hlau zoo, txo cov nqi, thiab txuag cov peev txheej hlau, tshwj xeeb hauv cov txheej txheem nruam casting. Tsis tas li ntawd, ferrosilicon nthuav tawm cov khoom desulfurization thiab muaj qhov zoo xws li lub ntiajteb txawj nqus siab thiab muaj zog nkag.
Hauv cov ntsiab lus, ferrosilicon ua tau zoo ua tiav cov kev cai deoxidation ntawm steelmaking thaum muab cov yam ntxwv tsim nyog rau alloying thiab txhim kho steel zoo.
Tsis tas li ntawd, nws tsim nyog hais tias ferrosilicon hmoov nthuav tawm cov khoom siv hluav taws xob zoo tshaj plaws thaum raug kub hnyiab, ua rau nws muaj txiaj ntsig zoo hauv kev lag luam steel. Nws thawj daim ntawv thov suav nrog ua tus neeg sawv cev cua sov rau steel ingot caps, txheej txheem uas ua kom muaj txiaj ntsig zoo thiab rov ua haujlwm ntawm steel ingots.
Kev lag luam hlau cam khwb cia siab heev ntawm kev siv ferrosilicon ua ob qho tib si inoculant thiab nodularizing tus neeg sawv cev. Cam khwb cia hlau tuav qhov tseem ceeb hauv kev lag luam niaj hnub no vim nws txoj kev lag luam zoo dua hlau, nrog rau nws tus nqi qis, yooj yim melatability, thiab tshwj xeeb casting zog. Tsis tas li ntawd, cam khwb cia hlau nthuav tawm cov kev poob siab zoo dua piv rau cov hlau thiab cov hlau nplaum, nrog rau nws cov cuab yeej cuab tam los yog txawm tias txuam nrog cov hlau. Txhawm rau txhim kho cov khoom siv hlau, qhov sib ntxiv ntawm ferrosilicon plays lub luag haujlwm tseem ceeb. Los ntawm kev koom ua ke ib qho tshwj xeeb ntawm ferrosilicon rau hauv cam khwb cia hlau, tsim cov carbides hauv hlau tuaj yeem tiv thaiv thaum ua kom yooj yim rau nag lossis daus thiab spheroidization ntawm graphite. Raws li qhov tshwm sim, ferrosilicon ua haujlwm tseem ceeb inoculant, pab hauv nag lossis daus ntawm graphite, thiab tus neeg sawv cev spheroidizing hauv kev tsim cov hlau ductile.
High-silicon ferrosilicon, tseem hu ua siliceous alloy, yog feem ntau siv los ua tus neeg sawv cev txo qis hauv kev lag luam ferroalloy rau kev tsim cov pa roj carbon tsawg ferroalloys. Qhov no feem ntau yog vim nws cov tshuaj lom neeg tshwj xeeb ntawm silicon thiab oxygen, nrog rau nws cov ntsiab lus carbon tsawg. Kev siv cov high-silicon ferrosilicon pab txo cov pa roj carbon ntau hauv ferroalloys, ua rau nws yog ib qho tseem ceeb ntawm cov txheej txheem ntawm ferroalloys.
Cov txheej txheem Pidgeon ntawm magnesium smelting feem ntau siv 75 # ferrosilicon thaum lub sij hawm kub kub smelting ntawm hlau magnesium. Cov kauj ruam tseem ceeb no suav nrog kev hloov cov magnesium hauv CaO.MgO, thiab rau txhua tuj ntawm cov hlau magnesium tsim, kwv yees li 1.2 tons ntawm ferrosilicon tau noj. Qhov tseem ceeb ntawm ferrosilicon hauv kev tsim cov hlau magnesium tsis tuaj yeem kwv yees.
Ferrosilicon hmoov, txawm hauv av los yog atomized, pom siv ntau yam kev siv tshaj li nws cov pa siv hauv metallurgy. Piv txwv li, nws yog feem ntau ua hauj lwm raws li ib tug ncua sij hawm nyob rau hauv cov ntxhia ua hauj lwm pab txhawb kev sib cais zoo dua thiab concentration ntawm txawv hlau ore. Ib yam li ntawd, hauv kev lag luam vuam pas nrig, ferrosilicon hmoov ua rau cov khoom siv zoo heev uas txhim kho qhov zoo ntawm cov welds thiab txhim kho cov kav ntev. Tsis tas li ntawd, high-silicon ferrosilicon pom kev siv hauv kev lag luam tshuaj raws li cov khoom siv raw rau kev tsim cov khoom siv silicone uas muaj cov khoom tshwj xeeb xws li kub tsis kam, tiv thaiv dej, thiab hluav taws xob rwb thaiv tsev. Yog li, txawm tias koj ua haujlwm hauv metallurgy los yog tsis, ferrosilicon hmoov kuj tseem muaj qee yam tseem ceeb los muab rau kev txhim kho kev ua haujlwm thiab cov khoom ntawm ntau yam khoom thiab cov ntaub ntawv.
Qhov kev thov rau ferrosilicon yog tsav los ntawm nws ntau yam kev siv hauv kev lag luam xws li steelmaking, foundry, thiab ferroalloy. Peb qhov kev lag luam no ib leeg noj 90% ntawm tag nrho cov ferrosilicon tsim tawm thoob ntiaj teb. Hom ferrosilicon nrov tshaj plaws yog 75% ferrosilicon, uas yog siv dav hauv ntau yam lag luam. Hauv kev tsim steel, ib ncig ntawm 3-5 kilograms ntawm 75% ferrosilicon yog xav tau rau txhua tuj ntawm cov hlau tsim. Zuag qhia tag nrho, ntau yam thiab kev ntseeg siab ntawm ferrosilicon ua rau nws yog ib qho tseem ceeb hauv ntau cov txheej txheem kev lag luam.
