Ferrosiliconyog ib qho hlau thiab silicon alloy.Ferrosilicon yog coke, steel chips, quartz (los yog silica) raws li raw cov ntaub ntawv, smelted los ntawm hluav taws xob rauv ua los ntawm hlau silicon alloy.Vim silicon thiab oxygen yog ib qho yooj yim mus ua ke rau hauv silicon dioxide, yog li ferric silicon feem ntau yog siv los ua deoxidizer hauv steelmaking.Nyob rau tib lub sijhawm, vim SiO2 ua kom muaj cua sov ntau, deoxidizing tib lub sijhawm, nws kuj tseem muaj txiaj ntsig los txhim kho qhov kub thiab txias ntawm cov hlau molten.Tam sim no, ferrosilicon kuj tseem siv tau los ua cov khoom siv alloying additive, dav siv hauv qis. alloy structural steel, caij nplooj ntoos hlav steel, bearing steel, tshav kub-resistant steel thiab hluav taws xob silicon steel, ferrosilicon nyob rau hauv ferroalloy ntau lawm thiab tshuaj kev lag luam, feem ntau yog siv los txo tus neeg sawv cev.

(1) Siv los ua deoxidizer thiab alloying tus neeg sawv cev hauv kev lag luam steelmaking.Yuav kom tau txais cov khoom tsim nyog tshuaj muaj pes tsawg leeg ntawm cov hlau thiab xyuas kom cov hlau zoo, nyob rau theem kawg ntawm steelmaking yuav tsum deoxidized, silicon thiab oxygen ntawm cov tshuaj affinity yog Zoo, yog li ferrosilicate yog ib qho muaj zog deoxidizing tus neeg sawv cev siv rau nag lossis daus thiab diffusion deoxidization.Ntxiv qee qhov nyiaj ntawm silicon hauv cov hlau tuaj yeem txhim kho lub zog, hardness thiab elasticity ntawm cov hlau, yog li nyob rau hauv smelting ntawm cov qauv hlau (muaj silicon 0.40- 1.75%), cuab yeej hlau (muaj Sio.30-1.8%), caij nplooj ntoos hlav steel (muaj Sio.40-2.8%) thiab transformer silicon steel (muaj silicon 2.81-4.8%), ferrosilicon kuj yog siv los ua tus neeg sawv cev alloying. tib lub sijhawm, txhim kho cov kev suav nrog thiab txo cov ntsiab lus ntawm cov ntsiab lus roj hauv cov hlau molten yog cov cuab yeej tshiab zoo los txhim kho steel zoo, txo nqi thiab txuag hlau.Nws yog tshwj xeeb tshaj yog tsim rau deoxidization ntawm moltensteel hauv nruam casting.Nws tau raug pov thawj los ntawm kev xyaum hais tias ferosilicate tsis tsuas yog ua tau raws li qhov yuav tsum tau ua ntawm deoxidization ntawm steel ua, tab sis kuj muaj desulfurization kev ua tau zoo thiab muaj qhov zoo ntawm qhov sib piv loj thiab muaj zog nkag.

Tsis tas li ntawd, nyob rau hauv kev lag luam steel, ferosilicon hmoov feem ntau yog siv los ua tus neeg sawv cev ingot cap cua sov los txhim kho qhov zoo thiab rov qab los ntawm cov ingot, ua kom zoo dua cov yam ntxwv uas cov hmoov ferosilicon tuaj yeem muab cov cua sov ntau ntawm qhov siab. kub.

(2) Siv los ua inoculant thiab spheroidizer hauv kev lag luam cam khwb cia hlau.Cast hlau yog cov khoom siv hlau tseem ceeb hauv kev lag luam niaj hnub.Nws yog pheej yig dua li cov hlau, yooj yim rau yaj thiab smelt, thiab muaj kev ua haujlwm zoo tshaj plaws thiab muaj peev xwm aseismic zoo dua li steel.Ductile hlau, tshwj xeeb tshaj yog, muaj cov khoom siv sib npaug los yog ze rau cov hlau.Ntxiv cov nqi ntawm ferrosilicon hauv cam khwb cia hlau tuaj yeem tiv thaiv kev tsim cov carbide hauv hlau, txhawb cov nag lossis daus thiab spheroidization ntawm graphite, yog li hauv kev tsim cov hlau cam khwb cia nodular, ferrosilicon yog ib qho tseem ceeb inoculant (los pab nag lossis daus ntawm graphite) thiab spheroidizer.

(3) siv los txo tus neeg sawv cev hauv ferroalloy ntau lawm.Tsis yog tsuas yog cov tshuaj affinity ntawm silicon thiab oxygen zoo, tab sis cov pa roj carbon cov ntsiab lus ntawm siab silicon ferrosilicon yog tsawg heev.Yog li ntawd, siab silicon ferrosilicon (los yog siliceous alloy) yog ib tug nquag siv txo. tus neeg sawv cev hauv kev tsim cov pa roj carbon tsawg ferroalloy hauv kev lag luam ferroalloy.

(4) 75 # ferrosilicate feem ntau yog siv rau hauv cov txheej txheem kub kub smelting ntawm magnesium hauv Pijiang magnesium smelting txheej txheem, cov magnesium hauv CaO.MgO yog hloov tawm, txhua ib tuj ntawm magnesium yuav haus txog 1.2 tons ntawm ferrosilicate, uas plays ib tug zoo heev. lub luag haujlwm hauv kev tsim cov magnesium.

(5) rau lwm lub hom phiaj.Grinded los yog atomized ferrosilicon hmoov yuav siv tau raws li ib tug ncua sij hawm nyob rau hauv cov ntxhia ua kev lag luam.Nws yuav siv tau raws li txheej rau electrode nyob rau hauv electrode manufacturing kev lag luam.High silicon ferrosilicon nyob rau hauv cov tshuaj kev lag luam yuav siv tau los tsim. silicone thiab lwm yam khoom.

Ntawm cov ntawv thov no, steelmaking, foundry thiab ferroalloy industries yog cov neeg siv ntau tshaj plaws ntawm ferrosilicate.Ua ke, lawv siv ntau tshaj 90% ntawm ferrosilicon.Nyob rau ntau qib sib txawv ntawm ferrosilicon, feem ntau siv dav yog 75% ferrosilicon.In steelmaking kev lag luam. , txog 3-5kg75% ferrosilicon yog siv rau txhua 1t ntawm cov hlau tsim.
