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 hlau, yooj yim rau yaj thiab smelt, muaj zoo heev casting zog, thiab muaj av qeeg zoo dua cov hlau. Hauv particular, cov khoom siv hluav taws xob ntawm cov khoom siv hlau ncav cuag lossis ze rau cov hlau. 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.
Siv los ua tus neeg sawv cev txo qis hauv ferroalloy ntau lawm. Tsis tsuas yog silicon muaj cov tshuaj lom neeg zoo nrog oxygen, tab sis cov ntsiab lus ntawm ferrosilicon kuj tsawg heev. Yog li ntawd, high-silicon ferrosilicon (los yog silicon alloy) yog ib qho uas feem ntau siv los txo tus neeg sawv cev hauv kev lag luam ferroalloy thaum tsim cov pa roj carbon tsawg ferroalloys.
Nyob rau hauv Pidgeon txoj kev ntawm magnesium smelting, 75 # ferrosilicon feem ntau yog siv rau high-temperature smelting ntawm hlau magnesium. CaO. yog hloov nrog magnesium hauv MgO. Nws yuav siv li 1.2 tons ntawm ferrosilicon ib tuj los tsim ib tuj ntawm hlau magnesium, uas plays lub luag haujlwm tseem ceeb hauv kev tsim cov hlau magnesium. nyhuv.
Siv lwm txoj kev. Ferrosilicon hmoov uas tau ua hauv av los yog atomized tuaj yeem siv tau raws li lub sijhawm tshem tawm hauv kev lag luam ntxhia. Nws tuaj yeem siv los ua txheej txheej rau vuam rods hauv kev lag luam vuam pas nrig. Hauv kev lag luam chemical, high-silicon ferrosilicon tuaj yeem siv los ua cov khoom xws li silicone.
Kev lag luam steelmaking, foundry kev lag luam thiab ferroalloy kev lag luam yog cov neeg siv loj tshaj plaws ntawm ferrosilicon. Ua ke lawv haus ntau dua 90% ntawm ferrosilicon. Tam sim no, 75% ntawm ferrosilicon yog dav siv. Hauv kev lag luam steelmaking, kwv yees li 3-5kg ntawm 75% ferrosilicon yog siv rau txhua tuj ntawm cov hlau tsim.
