Daim ntawv thov:
(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). kuj tseem siv los ua tus neeg sawv cev rau kev sib tsoo thaum nws los txog rau silicon steel rau transformers (muaj SiO. 40-2.8%) thiab transformer silicon steel (muaj 2.81-4.8% silicon). Tsis tas li ntawd, 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 steel ingots los ntawm kev noj kom zoo dua qhov tseeb tias ferrosilicon hmoov tuaj yeem tso tawm ntau cov cua sov thaum 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 cov hlau nplaum, nws cov khoom siv kho tshuab 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 kev siv txo tus neeg sawv cev hauv kev lag luam ferroalloy thaum tsim cov pa roj carbon monoxide 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 ferrosilicon, 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.
