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 thaum 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), cov cuab yeej steel (muaj SiO.30-1.8%), Ferrosilicon kuj yog siv los ua tus neeg sawv cev alloying nyob rau hauv lub caij nplooj ntoos hlav steel (muaj SiO. 40-2.8%) thiab silicon steel rau transformers (muaj 2.81-4.8% silicon).
ferro silicon 70
Hauv kev lag luam steelmaking, ferrosilicon hmoov feem ntau yog siv los ua cov khoom cua sov rau steel ingot caps los txhim kho qhov zoo thiab rov qab tus nqi ntawm cov hlau ingots los ntawm kev ua kom zoo dua ntawm qhov tseeb tias ferrosilicon hmoov tuaj yeem tso tawm ntau cov cua sov thaum kub kub.
ultra-low carbon ferrosilicon
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 cov khoom zoo tshaj plaws thiab kev co zoo dua li cov hlau. Tshwj xeeb tshaj yog cov hlau nplaum, nws cov khoom siv kho tshuab yog sib npaug los yog ze rau cov hlau. Mechanical cwj pwm. 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.
