High Quality Carbon Ferro Silicon Alloy Rau Casting Thiab Steelmaking Additive

Ferrosilicon yog cov hlau alloy uas muaj hlau thiab silicon. Ferrosilicon yog cov hlau-silicon alloy ua los ntawm coke, steel scraps, quartz (los yog silica) ua raw cov ntaub ntawv thiab smelted nyob rau hauv lub cub hluav taws xob.

Siv ua deoxidizer thiab alloying tus neeg sawv cev hauv kev lag luam steelmaking. Txhawm rau kom tau txais cov hlau nrog cov tshuaj muaj txiaj ntsig zoo thiab ua kom cov hlau zoo, deoxidation yuav tsum tau ua. Cov tshuaj affinity ntawm silicon thiab oxygen yog loj heev, yog li ferrosilicon yog ib tug muaj zog deoxidizer nyob rau hauv steelmaking rau nag lossis daus thiab diffusion deoxidation. Txhim kho cov duab ntawm kev suav 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 cov nqi thiab txuag hlau. Nws yog tshwj xeeb tshaj yog haum rau nruam casting molten steel deoxidation yuav tsum tau. Kev xyaum tau ua pov thawj tias ferrosilicon tsis yog tsuas yog ua tau raws li qhov yuav tsum tau ua ntawm deoxidation ntawm steelmaking, tab sis kuj muaj desulfurization kev ua tau zoo thiab muaj qhov zoo ntawm lub ntiajteb txawj nqus loj thiab muaj zog nkag.

Nws yog siv los ua inoculant thiab tus neeg sawv cev nodularizing 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 thiab smelt, muaj cov khoom zoo heev thiab kev poob siab zoo dua li cov hlau. Hauv particular, cov hlau nplaum, nws cov khoom siv kho tshuab yog nyob ntawm lossis ze rau 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 ntawd, nyob rau hauv zus tau tej cov ductile hlau, ferrosilicon yog ib qho tseem ceeb inoculant thiab spheroidizer.

Nws yog siv los ua tus neeg sawv cev txo qis hauv kev tsim cov ferroalloys. Tsis tsuas yog cov tshuaj affinity ntawm silicon thiab oxygen siab, tab sis cov pa roj carbon ntsiab lus ntawm high-silicon ferrosilicon yog tsawg heev. Yog li ntawd, high-silicon ferrosilicon (los yog siliceous alloy) yog ib qho uas feem ntau siv los txo tus neeg sawv cev hauv kev tsim cov pa roj carbon tsawg hauv kev lag luam ferroalloy.
