Lub luag haujlwm ntawm ferrosilicon
1, siv los ua deoxidizer thiab alloying tus neeg sawv cev hauv kev lag luam steelmaking: txhawm rau kom tau txais cov hlau zoo thiab cov hlau nrog cov tshuaj tsim nyog, nyob rau theem tom ntej ntawm steelmaking yuav tsum tau deoxidized, cov tshuaj affinity ntawm silicon thiab oxygen yog loj heev, yog li ferrosilicon yog ib qho muaj zog deoxidizer rau nag lossis daus thiab diffusion hauv steelmaking. Ntxiv qee qhov nyiaj ntawm silicon rau cov hlau tuaj yeem txhim kho lub zog, hardness thiab elasticity ntawm cov hlau, yog li thaum smelting steel qauv (muaj silicon 0.40-1.75%), cov cuab yeej steel (muaj SiO. . tus neeg sawv cev alloying. Nyob rau tib lub sijhawm, daim ntawv suav nrog txo cov ntsiab lus ntawm cov ntsiab lus roj hauv cov kua hlau, uas yog cov cuab yeej tshiab zoo los txhim kho steel zoo, txo nqi thiab txuag hlau. Nws yog tsim rau nruam casting molten steel deoxidation yuav tsum tau. Kev xyaum tau ua pov thawj tias ferrosilicon tsis tsuas yog ua tau raws li qhov xav tau ntawm deoxidation ntawm steelmaking, tab sis kuj muaj desulfurization kev ua tau zoo thiab muaj cov yam ntxwv ntawm qhov hnyav piv thiab muaj zog nkag mus.
2, hauv kev lag luam cam khwb cia hlau siv los ua inoculant thiab nodule tus neeg sawv cev: cam khwb cia 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 smelting, nrog kev ua haujlwm zoo casting thiab muaj peev xwm zoo dua seismic dua li hlau. Cov hlau ductile, uas nws cov cuab yeej cuab tam ncav cuag lossis mus txog cov khoom siv hluav taws xob ntawm cov hlau. Ntxiv ib qho nyiaj ntawm ferrosilicon rau cam khwb cia hlau tuaj yeem tiv thaiv kev tsim cov carbides hauv hlau thiab txhawb cov nag lossis daus thiab spheroidization ntawm graphite, yog li hauv kev tsim cov hlau ductile, ferrosilicon yog ib qho tseem ceeb inoculant (pab precipitate graphite) thiab spheroidization tus neeg sawv cev;
3, siv los ua tus neeg sawv cev txo qis hauv kev tsim cov ferroalloy: tsis yog tsuas yog cov tshuaj lom neeg ntawm silicon thiab oxygen yog qhov loj heev, tab sis kuj tseem muaj cov ntsiab lus carbon ntawm high-silicon ferrosilicon tsawg heev. Yog li ntawd, high-silicon ferrosilicon (los yog siliceous alloy) yog ib qho kev txo tus neeg sawv cev uas feem ntau siv hauv kev lag luam ferroalloy los tsim cov pa roj carbon tsawg ferroalloys.
4, nyob rau hauv lwm yam kev siv: av los yog atomized ferrosilicon hmoov, nyob rau hauv cov ntxhia ua kev lag luam yuav siv tau raws li ib tug ncua sij hawm. Nyob rau hauv lub vuam pas nrig manufacturing kev lag luam yuav siv tau raws li welding pas nrig txheej. High silicon hlau silicon yog siv nyob rau hauv kev lag luam tshuaj los ua cov khoom xws li silicone.
