ferrosilicon yog dab tsi?
Ferrosilicon yog ib qho ferroalloy uas muaj hlau thiab silicon.Ferrosilicon yog ferrosilicon alloy ua los ntawm coke, steel shavings, quartz (los yog silica) thiab smelted nyob rau hauv lub cub hluav taws xob;
Kev siv ferrosilicon:
1. Ferrosilicon yog ib qho tseem ceeb deoxidizer hauv kev lag luam steelmaking.Hauv steelmaking, ferrosilicon yog siv rau nag lossis daus deoxidation thiab diffusion deoxidation.Cib hlau kuj tseem siv los ua tus neeg sawv cev alloying hauv steelmaking.
2. Siv los ua inoculant thiab nodulizer hauv kev lag luam cam khwb cia hlau.Nyob rau hauv zus tau tej cov ductile hlau, 75 ferrosilicon yog ib qho tseem ceeb inoculant (los pab precipitate graphite) thiab nodularizer.
3. 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, high-silicon ferrosilicon (los yog silicon alloy) yog ib tug txo tus neeg sawv cev uas feem ntau siv nyob rau hauv zus tau tej cov low-carbon ferroalloys nyob rau hauv lub ferroalloy kev lag luam.
Dab tsi yog ferrosilicon nplej?
Ferrosilicon hais yog tsim los ntawm crushing ferrosilicon rau hauv me me ntawm ib qho kev faib ua feem thiab lim los ntawm ib tug sieve nrog ib tug xov tooj ntawm meshes.Cov khoom me me uas tau tshuaj xyuas tam sim no yog siv los ua inoculants rau foundries hauv khw.
Muab cov granularity ntawm ferrosilicon hais: 0.2-1mm, 1-3mm, 3-8mm, los yog kho raws li tus neeg yuav tsum tau muaj;
Qhov zoo ntawm ferrosilicon hais:
Ferrosilicon pellets tuaj yeem siv tsis tau tsuas yog hauv kev lag luam steelmaking tab sis kuj yog cov khoom siv hlau feem ntau siv hauv kev lag luam cam khwb cia hlau.Qhov no feem ntau yog vim ferrosilicon pellets tuaj yeem siv los ntawm cov tuam txhab cam khwb cia hlau los hloov inoculants thiab nodularizers.Hauv kev lag luam cam khwb cia hlau, tus nqi ntawm ferrosilicon pellets nyob deb qis dua hlau, thiab yooj yim dua melted, yog castable ferroalloy khoom.
