Kev siv Ferrosilicon yog dab tsi?
(1) 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 kawg 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. Ntxiv qee qhov nyiaj ntawm silicon rau cov hlau tuaj yeem txhim kho lub zog, hardness thiab elasticity ntawm cov hlau.
Yog li ntawd, nws yog dav siv nyob rau hauv smelting structural steel (muaj 0). tus neeg sawv cev alloying nyob rau hauv lub caij nplooj ntoos hlav steel (muaj SiO. 40-2.8%) thiab silicon steel rau transformers (muaj 2.81-4.8% silicon). Tsis tas li ntawd, nyob rau hauv kev lag luam steelmaking, ferrosilicon hmoov feem ntau yog siv los ua cov khoom cua sov rau steel ingot caps los txhim kho qhov zoo thiab rov qab tus nqi ntawm cov hlau ingots los ntawm kev ua kom zoo dua qhov tseeb tias ferrosilicon hmoov tuaj yeem tso tawm ntau cov cua sov thaum hlawv ntawm kub kub.
(2) 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 hlau, yooj yim rau yaj thiab smelt, muaj zoo heev casting zog thiab yog zoo dua li hlau nyob rau hauv kev co kuj. Tshwj xeeb tshaj yog ductile hlau, nws cov cuab yeej cuab tam yog sib npaug los yog ze rau cov hlau. Mechanical cwj pwm. 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. .
(3) 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 (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.
(4) Siv rau lwm yam. Hauv av los yog atomized ferrosilicon hmoov tuaj yeem siv los ua 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. High-silicon ferrosilicon yog siv hauv kev lag luam tshuaj los ua cov khoom xws li silicone.
Ntawm cov kev siv no, kev lag luam steelmaking, kev lag luam foundry thiab ferroalloy kev lag luam yog cov neeg siv ntau tshaj plaws ntawm ferrosilicon. Ua ke lawv haus ntau dua 90% ntawm ferrosilicon. Ntawm ntau hom ntawmfesi, 75% ferrosilicon yog tam sim no siv dav tshaj plaws. Hauv kev lag luam steelmaking, kwv yees li 3-5kg ntawm 75% ferrosilicon yog siv rau txhua tuj ntawm cov hlau tsim.
Ferrosilicon qib thiab tshuaj muaj pes tsawg leeg qib tshuaj lom neeg muaj pes tsawg leeg SiAlCaMnCrPSC Qhov ntau tsis loj dua FeSi75AI1.0-b72.0-80.0110.50.50.040.020.2 FeSi75AI1.5-b72.{15}. 01.510.50.50.040.020.2 Ferrosilicon yog siv hauv kev lag luam steel thiab casting Nws yog dav siv hauv kev lag luam thiab lwm yam kev lag luam. Ferrosilicon yog ib qho tseem ceeb deoxidizer hauv kev lag luam steelmaking. Nyob rau hauv lub teeb steel, 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.

Ntxiv qee qhov nyiaj ntawm silicon rau cov hlau tuaj yeem txhim kho lub zog, hardness thiab elasticity ntawm cov hlau, ua kom cov hlau nplaum permeability ntawm cov hlau, thiab txo cov hysteresis poob ntawm transformer steel. General steel muaj {{0}}.15%-0.35% silicon, structural steel muaj 0.40%-1.75% silicon , cov cuab yeej hlau muaj 0.30% -1.80% silicon, caij nplooj ntoos hlav steel muaj 0.40% -2.80% silicon, thiab stainless acid-resistant steel muaj Silicon 3.40% ~ 4.00% , kub-resistant steel muaj silicon 1.00% ~ 3.00%, silicon steel muaj silicon 2% ~ 3% lossis siab dua.

Siab silicon ferrosilicon los yog siliceous alloys yog siv nyob rau hauv ferroalloy kev lag luam raws li txo cov neeg ua hauj lwm rau zus tau tej cov carbon ferroalloys tsawg.
Ferroalloystuaj yeem siv los ua ib qho inoculant rau ductile hlau thaum ntxiv rau cam khwb cia hlau, thiab tuaj yeem tiv thaiv kev tsim cov carbides, txhawb cov nag lossis daus thiab spheroidization ntawm graphite, thiab txhim kho kev ua haujlwm ntawm cam khwb cia hlau.
Ntxiv rau,ferro siliconhmoov yuav siv tau raws li ib tug ncua sij hawm nyob rau hauv cov ntxhia ua kev lag luam thiab raws li ib tug txheej rau vuam rods nyob rau hauv lub vuam pas nrig manufacturing kev lag luam; high-silicon ferrosilicon tuaj yeem siv rau hauv kev lag luam hluav taws xob los npaj semiconductor ntshiab silicon thiab hauv kev lag luam tshuaj los tsim cov khoom siv silicone, thiab lwm yam.
Hauv kev lag luam steelmaking, kwv yees li 3 txog 5kg ntawm 75%hlau alloyyog siv rau txhua tuj ntawm steel tsim.
