Ferrosilicon hmoov feem ntau yog siv los ua deoxidizer thiab alloying tus neeg sawv cev
Hauv kev lag luam steelmaking, txhawm rau kom tau cov hlau nrog cov tshuaj tsim nyog thiab ua kom cov hlau zoo, deoxidation yuav tsum tau ua nyob rau tom qab theem ntawm steelmaking. Cov tshuaj affinity ntawm silicon thiab oxygen nyob rau hauv ferrosilicon hmoov yog loj heev, yog li ferrosilicon hmoov Nws yog ib tug haib deoxidizer rau steelmaking thiab yog siv 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.
Ferrosilicon hmoov tuaj yeem siv los ua tus neeg sawv cev hauv kev tsim cov ferroalloys
Hauv cov txheej txheem ferroalloy ntau lawm, ferrosilicon hmoov tsis tsuas yog muaj cov tshuaj lom neeg muaj txiaj ntsig ntawm silicon thiab oxygen, tab sis kuj tseem muaj cov ntsiab lus ntawm cov roj silicon ferrosilicon hmoov tsawg heev. Yog li ntawd, high-silicon ferrosilicon hmoov (los yog silicon alloy) yog siv los txo tus neeg sawv cev hauv kev lag luam ferroalloy thaum tsim cov pa roj carbon tsawg ferroalloys.
Ferrosilicon hmoov nyob rau hauv kev lag luam cam khwb cia hlau feem ntau yog siv los ua inoculant thiab spheroidizing tus neeg sawv cev.
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 zoo dua hlau nyob rau hauv av qeeg kuj. Tshwj xeeb, cov khoom siv hluav taws xob ntawm cov khoom siv hlau ncav cuag lossis ze rau cov hlau. Ntxiv ib qho nyiaj ntawm ferrosilicon hmoov 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 spheroidization. tus neeg sawv cev.
