Ferrosilicon yog ib qho ferroalloy uas muaj hlau thiab silicon.Ferrosilicon yog hlau-silicon alloy ua los ntawm smelting coke, steel shavings, thiab quartz (los yog silica) nyob rau hauv lub cub hluav taws xob.Txij li thaum silicon thiab oxygen tau yooj yim ua ke rau hauv silicon dioxide, ferrosilicon feem ntau yog siv los ua deoxidizer hauv steelmaking.Nyob rau tib lub sijhawm, vim tias SiO2 tsim cov cua sov ntau, nws kuj tseem muaj txiaj ntsig los ua kom kub ntawm cov hlau molten thaum deoxidation.Nyob rau tib lub sijhawm, ferrosilicon kuj tuaj yeem siv los ua cov khoom siv alloying ntxiv, thiab tau dav siv hauv cov hlau tsis tshua muaj hlau, lub caij nplooj ntoos hlav steel, cov kabmob hlau, cov hlau tsis muaj cua sov thiab hluav taws xob silicon steel.Ferrosilicon feem ntau yog siv los ua tus neeg sawv cev txo qis hauv ferroalloy ntau lawm thiab kev lag luam tshuaj.
Ferroalloy tsim los ntawm hlau thiab silicon (siv silica, steel, thiab coke ua raw cov ntaub ntawv, silicon uas tau raug txo los ntawm ib tug kub ntawm 1500-1800 degrees yog melted nyob rau hauv molten hlau los ua ib tug ferrosilicon alloy).Nws yog ib qho tseem ceeb alloy ntau yam hauv kev lag luam smelting.
Khoom piav qhia
(1) Siv los ua deoxidizer thiab alloying agents hauv kev lag luam steel.Txhawm rau kom tau txais kev tsim nyog tshuaj muaj pes tsawg leeg thiab lav qhov zoo ntawm cov hlau, nyob rau theem kawg ntawm cov hlau yuav tsum tau deoxidized.Cov tshuaj affinity ntawm silicon thiab oxygen yog loj heev, yog li ferrosilicon muaj zog deoxidizer siv nyob rau hauv sedimentation thiab diffusion deoxidation ntawm steel-ua.Ntxiv qee qhov nyiaj ntawm silicon hauv cov hlau, tuaj yeem txhim kho lub zog, hardness thiab elasticity ntawm hlau.
(2) Siv los ua tus neeg sawv cev nucleating thiab spheroidizing tus neeg sawv cev hauv kev lag luam hlau.cam khwb cia hlau yog ib yam tseem ceeb niaj hnub muaj hlau cov ntaub ntawv, Nws yog ntau pheej yig dua hlau, yooj yim rau yaj refining, nrog zoo heev casting kev ua tau zoo thiab seismic muaj peev xwm yog ntau zoo dua hlau.Tshwj xeeb tshaj yog cov nodular cam khwb cia hlau, Nws mechanical zog ntawm los yog nyob ze ntawm lub mechanical zog ntawm steel.Ntxiv ib qho nyiaj ntawm silicon hauv cam khwb cia hlau tuaj yeem tiv thaiv cov hlau hauv kev tsim, txhawb cov nag lossis daus ntawm graphite thiab carbide spheroidizing.Yog li nyob rau hauv nodular hlau ntau lawm, ferrosilicon yog ib yam ntawm cov tseem ceeb inoculants (Pab cais tawm graphite) thiab spheroidizing tus neeg sawv cev.
