Ferrosilicon hmoov yog cov hlau alloy uas muaj hlau thiab silicon, uas yog tom qab ntawd hauv av rau hauv cov hmoov uas siv los ua tus neeg sawv cev deoxidising hauv steel thiab hlau ua, thiab tseem yog cov khoom siv raw rau hydrogen ntau lawm.
Kev siv tshwj xeeb ntawm ferrosilicon hmoov yog raws li hauv qab no:
1: Siv los ua deoxidiser thiab alloying tus neeg sawv cev hauv kev lag luam steelmaking;
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, cuab yeej steel, caij nplooj ntoos hlav steel, thiab silicon steel rau transformers.
2: Siv ua inoculant thiab spheroidising tus neeg sawv cev hauv kev lag luam cam khwb cia hlau.
Ntxiv ib qho nyiaj ntawm ferrosilicon hauv cam khwb cia hlau tuaj yeem tiv thaiv kev tsim cov carbides hauv hlau, txhawb cov nag lossis daus ntawm graphite thiab spheroidisation, yog li hauv kev tsim cov hlau, ferrosilicon yog ib qho tseem ceeb yug me nyuam (los pab precipitate graphite) thiab spheroidising tus neeg sawv cev.
3: Siv los txo tus neeg sawv cev hauv ferroalloy ntau lawm
Tsis tsuas yog cov tshuaj affinity ntawm silicon thiab oxygen yog loj heev, tab sis kuj cov pa roj carbon ntsiab lus ntawm siab silica ferrosilicon yog tsawg heev. Yog li ntawd, siab silica ferrosilicon (los yog silica alloy) yog ib hom kev txo tus neeg sawv cev uas feem ntau siv los tsim cov roj carbon ferroalloys hauv kev lag luam ferroalloy.
4 ib:. Siv hauv lwm qhov chaw. Finely hauv av los yog atomised kho ferrosilicon hmoov yuav siv tau raws li ib tug ncua kev kawm ntawv theem nyob rau hauv cov ntxhia ua kev lag luam.
