Dab tsi yog cov ntawv thov ntawm ferrosilicon?

Ferrosilicon, ib qho alloy ntawm silicon thiab hlau, muaj nyob rau hauv 45%, 65%, 75% thiab 90% silicon qib.Nws siv dav heev, ces lub chaw tsim khoom ferrosilicon Anhui Fitech Materials Co., Ltd yuav tshuaj xyuas nws cov kev siv tshwj xeeb los ntawm peb lub ntsiab lus hauv qab no.

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 nrog cov tshuaj muaj txiaj ntsig zoo thiab ua kom cov hlau zoo, deoxidation yuav tsum tau ua thaum kawg ntawm steelmaking.Cov tshuaj affinity ntawm silicon thiab oxygen yog loj heev.Yog li ntawd, ferrosilicon yog ib qho muaj zog deoxidizer rau steelmaking, uas yog siv 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, ferrosilicon kuj tseem siv los ua tus neeg sawv cev alloying thaum smelting steel qauv (muaj silicon 0.40-1.75%), cov cuab yeej hlau (muaj silicon 0.30-1.8%), caij nplooj ntoos hlav steel (muaj silicon 0.40-2.8%) thiab silicon steel rau transformer ( muaj silicon 2.81-4.8%).

Tsis tas li ntawd, nyob rau hauv kev lag luam steel ua, ferrosilicon hmoov tuaj yeem tso tawm ntau cov cua sov hauv qhov kub thiab txias.Nws feem ntau yog siv los ua tus neeg sawv cev cua sov ntawm ingot cap los txhim kho qhov zoo thiab rov qab los ntawm ingot.

Thib ob, nws yog siv los 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 hlau thiab yooj yim rau yaj thiab smelt.Nws muaj cov khoom zoo heev casting thiab muaj peev xwm poob siab zoo dua li cov hlau.Tshwj xeeb tshaj yog nodular cam khwb cia hlau, nws cov cuab yeej cuab tam ncav cuag los yog mus kom ze rau cov khoom siv hlau.Ntxiv ib qho nyiaj ntawm ferrosilicon rau cam khwb cia hlau tuaj yeem tiv thaiv kev tsim cov carbide hauv hlau thiab txhawb cov nag lossis daus thiab spheroidization ntawm graphite.Yog li ntawd, ferrosilicon yog ib qho tseem ceeb inoculant (los pab precipitate graphite) thiab spheroidizing tus neeg sawv cev nyob rau hauv zus tau tej cov nodular cam khwb cia hlau.

Tsis tas li ntawd, nws yog siv los txo tus neeg sawv cev hauv ferroalloy ntau lawm.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, siab silicon ferrosilicon (los yog siliceous alloy) yog ib qho kev txo tus neeg sawv cev hauv kev tsim cov pa roj carbon tsawg ferroalloy hauv kev lag luam ferroalloy.
