Ferrosilicon yog 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.
Kev siv ferrosilicon:
(1) Ferrosilicon yog deoxidizer hauv kev lag luam steel. 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, ferrosilicon yog ib qho tseem ceeb inoculant (los pab precipitate graphite) thiab nodularizer.
(3) 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 (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.
(4) 75 # ferrosilicon feem ntau yog siv rau hauv cov txheej txheem kub kub ntawm cov hlau magnesium hauv Pidgeon txoj kev smelting magnesium. Nws siv txog 1.2 tons ntawm ferrosilicon rau txhua tuj ntawm cov hlau magnesium uas tsim, uas ua lub luag haujlwm zoo hauv kev tsim cov hlau magnesium.
(5) Siv rau hauv 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.
(6) Nws tuaj yeem siv los ua txheej txheej rau vuam rods hauv kev lag luam vuam pas nrig. High-silicon ferrosilicon tuaj yeem siv rau hauv kev lag luam tshuaj los ua cov khoom xws li silicone.
Tsis tas li ntawd, ferrosilicon hmoov tuaj yeem siv los ua lub sijhawm ncua kev lag luam hauv kev lag luam, thiab ua ib txheej rau vuam rods hauv kev lag luam vuam pas nrig. Hauv kev lag luam steelmaking, kwv yees li 3-5kg ntawm 75 feem pua ferrosilicon yog siv rau txhua tuj ntawm cov hlau tsim. Melting point: 75FeSi yog 1300 degree.
