Kev faib tawm ntawm ferrosilicon:
Ferrosilicon 75, feem ntau, ferrosilicon nrog cov ntsiab lus silicon ntawm 75%, qis carbon, phosphorus thiab sulfur cov ntsiab lus,
Ferrosilicon 72, feem ntau muaj 72% silicon, thiab cov ntsiab lus ntawm carbon, sulfur thiab phosphorus nyob rau hauv nruab nrab.
Ferrosilicon 65, ferrosilicon nrog 65% silicon cov ntsiab lus, kuj muaj cov ntsiab lus ntawm carbon, sulfur thiab phosphorus.
Lub luag haujlwm ntawm ferrosilicon hauv steelmaking:
Ua ntej: Nws yog siv los 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 siab heev, yog li ferrosilicon yog ib tug muaj zog deoxidizer rau steelmaking.Dej nag thiab diffusion deoxygenation.
Thib ob: Nws yog siv los ua inoculant thiab nodulizer 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 kev ua haujlwm zoo tshaj plaws thiab muaj peev xwm ua kom poob siab zoo dua li cov hlau.Ntxiv ib qho nyiaj ntawm ferrosilicon rau cam khwb cia hlau tuaj yeem tiv thaiv cov hlau los ntawm Form carbides, txhawb cov nag lossis daus thiab spheroidization ntawm graphite, yog li hauv kev tsim cov hlau ductile, ferrosilicon yog ib qho tseem ceeb inoculant thiab spheroidizer.
Thib peb: 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 yog qhov zoo, tab sis kuj muaj cov ntsiab lus carbon ntawm silicon ferrosilicon siab heev.Yog li ntawd, high-silicon ferrosilicon yog ib tug txo tus neeg sawv cev uas feem ntau siv nyob rau hauv zus tau tej cov uas tsis muaj carbon ferroalloys nyob rau hauv lub ferroalloy kev lag luam.
Plaub: Kev siv lub ntsiab ntawm ferrosilicon ntuj lumps yog ua tus neeg sawv cev alloying hauv steel ntau lawm.Nws tuaj yeem txhim kho hardness, lub zog, thiab corrosion kuj ntawm steel, thiab tseem tuaj yeem txhim kho weldability thiab machinability ntawm steel.
Thib tsib: Siv rau lwm qhov chaw.Finely hauv av los yog atomized ferrosilicon hmoov yuav siv tau raws li ib tug ncua kev kawm ntawv theem nyob rau hauv cov ntxhia ua kev lag luam.
