72 Ferrosilicon Hoobkas-ZhenAn

ZhenAn tusferrosiliconspecifications yog 3-8mm. Ferrosilicon hais yog hu ua silicon hais, uas yog, ferrosilicon inoculant, uas yog ib qho inoculant siv hauv steelmaking, ironmaking, thiab casting. Huijin ferrosilicon muaj qhov loj me me, tsis muaj hmoov zoo, muaj zog inoculation nyhuv dua li cov ferrosilicon zoo tib yam, thiab tsis tshua muaj siab tsim slag. Nws txo cov pinholes, txhim kho qhov zoo ntawm cov kav dej cam khwb cia, thiab txhim kho tus nqi dhau ntawm kev tshuaj xyuas ib zaug.

Siv ua deoxidizer thiab alloying tus neeg sawv cev hauv kev lag luam steelmaking. Txhawm rau kom tau txais cov hlau uas tsim nyog cov tshuaj muaj pes tsawg leeg thiab ua kom cov hlau zoo, deoxidation yuav tsum tau ua nyob rau theem kawg ntawm steelmaking. Cov tshuaj affinity ntawm silicon thiab oxygen yog loj heev, yog li ferrosilicon yog ib tug muaj zog deoxidizer rau steelmaking rau nag lossis daus thiab diffusion. deoxidation. Ntxiv qee qhov nyiaj ntawm silicon rau cov hlau tuaj yeem txhim kho lub zog, hardness thiab elasticity ntawm cov hlau. Yog li ntawd, nws yog dav siv nyob rau hauv smelting structural steel (muaj 0.40-1.75% silicon), cuab yeej steel (muaj SiO.30-1.8%), thiab caij nplooj ntoos hlav steel. (muaj SiO.

Nyob rau tib lub sijhawm, kev txhim kho cov duab ntawm kev suav nrog thiab txo cov ntsiab lus ntawm cov khoom siv 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 deoxidation yuav tsum tau ntawm nruam casting molten steel. 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 mus rau lub zog.

Siv ua inoculant thiab spheroidizing 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 thiab smelt, muaj zoo heev casting zog thiab zoo dua hlau nyob rau hauv av qeeg tsis kam. Tshwj xeeb, cov khoom siv hluav taws xob ntawm cov khoom siv hlau ncav cuag 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 cov 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 (pab kom precipitate graphite) thiab spheroidizing tus neeg sawv cev.

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