Lub luag haujlwm thiab kev faib tawm ntawm Ferrosilicon yog dab tsi?

Lub luag haujlwm ntawm ferrosilicon hauv steelmaking:

Ua ntej: siv los ua deoxidizer thiab alloying tus neeg sawv cev hauv kev lag luam steelmaking. Txhawm rau kom tau txais cov hlau uas tsim nyog cov tshuaj muaj pes tsawg leeg thiab ua kom cov hlau zoo, deoxidation yuav tsum tau ua nyob rau theem tom ntej ntawm steelmaking. Cov tshuaj affinity ntawm silicon thiab oxygen yog loj heev, yog li ferrosilicon yog ib tug muaj zog deoxidizer rau steelmaking rau nag lossis daus thiab diffusion. deoxidation.

Thib ob: siv los 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 zoo dua hlau nyob rau hauv av qeeg tsis kam. Ntxiv ib qho nyiaj ntawm ferrosilicon rau cam khwb cia hlau tuaj yeem tiv thaiv cov hlau los ntawm Nws cov ntaub ntawv carbides thiab txhawb cov nag lossis daus thiab spheroidization ntawm graphite. Yog li, ferrosilicon yog ib qho tseem ceeb inoculant thiab spheroidizing tus neeg sawv cev hauv kev tsim cov hlau hlau.

Thib peb: siv los txo tus neeg sawv cev hauv ferroalloy ntau lawm. Tsis tsuas yog cov tshuaj affinity ntawm silicon thiab oxygen siab heev, tab sis cov pa roj carbon ntsiab lus ntawm high-silicon ferrosilicon yog tsawg heev. Yog li ntawd, high-silicon ferrosilicon 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.

Plaub: Lub ntsiab siv ntawm ferrosilicon ntuj thaiv yog ua tus neeg sawv cev alloying hauv steel ntau lawm. Nws tuaj yeem txhim kho qhov hardness, lub zog, thiab corrosion kuj ntawm steel, thiab tseem tuaj yeem txhim kho cov weldability thiab processability ntawm steel.

Thib tsib: Siv rau lwm yam. Hauv av los yog atomized ferrosilicon hmoov tuaj yeem siv los ua lub sijhawm ncua hauv kev lag luam ntxhia.
