Lub luag haujlwm ntawm ferrosilicon hauv steelmaking:
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 siv nyob rau hauv steelmaking. Dej nag thiab diffusion deoxidation.
Lub luag haujlwm ntawm ferrosilicon hauv cam khwb cia hlau:
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 hlau, yooj yim rau yaj thiab smelt, muaj zoo heev casting zog thiab zoo dua hlau nyob rau hauv av qeeg tsis kam. Ntxiv ib qho nyiaj ntawm ferrosilicon rau cam khwb cia hlau tuaj yeem tiv thaiv cov hlau los ntawm Nws cov ntaub ntawv carbides thiab txhawb cov nag lossis daus thiab spheroidization ntawm graphite. Yog li, ferrosilicon yog ib qho tseem ceeb inoculant thiab spheroidizing tus neeg sawv cev hauv kev tsim cov hlau hlau.
Lub luag haujlwm ntawm ferrosilicon hauv ferroalloy ntau lawm:
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 yog ib qho uas feem ntau siv los txo tus neeg sawv cev hauv kev lag luam ferroalloy thaum tsim cov pa roj carbon tsawg ferroalloys.
Kev siv lub ntsiab ntawm ferrosilicon ntuj blocks yog ua tus neeg sawv cev alloying hauv steel ntau lawm. Nws tuaj yeem txhim kho qhov hardness, lub zog, thiab corrosion kuj ntawm steel, thiab tseem tuaj yeem txhim kho cov weldability thiab processability ntawm steel.
Ferrosilicon granules, hu ua ferrosilicon inoculants, feem ntau yog siv hauv cam khwb cia hlau. Hauv kev lag luam cam khwb cia hlau, nws yog pheej yig dua li cov hlau, yooj yim rau yaj thiab smelt, muaj cov khoom zoo heev, thiab muaj av qeeg zoo dua li cov hlau. Hauv particular, cov khoom siv hluav taws xob ntawm cov khoom siv hlau ncav cuag lossis ze rau cov hlau.
High silicon ferrosilicon hmoov muaj cov ntsiab lus carbon tsawg heev. Yog li ntawd, high-silicon ferrosilicon hmoov (los yog silicon alloy) yog siv los txo tus neeg sawv cev hauv kev lag luam ferroalloy thaum ua cov pa roj carbon tsawg ferroalloys. Siv lwm txoj kev. Hauv av los yog atomized ferrosilicon hmoov tuaj yeem siv los ua lub sijhawm ncua hauv kev lag luam ntxhia. Hauv kev lag luam vuam pas nrig, nws tuaj yeem siv los ua cov txheej txheem vuam rods. High silicon ferrosilicon hmoov tuaj yeem siv rau hauv kev lag luam tshuaj los tsim cov khoom siv silicone thiab lwm yam khoom.
