Semiconductor Silicon Slag
(1) Siv 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.
(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 li cov hlau, yooj yim rau yaj thiab smelt, muaj kev ua haujlwm zoo tshaj plaws thiab kev co zoo dua li cov hlau. Tshwj xeeb tshaj yog ductile hlau, 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 spheroidization. tus neeg sawv cev.
Hnub ci Silicon Slag
(3) Siv los ua tus neeg sawv cev txo qis. 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 ncua 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.
Ferrosilicon yog ib qho tseem ceeb deoxidizer nyob rau hauv steelmaking kev lag luam thiab yog siv rau nag lossis daus deoxidation thiab diffusion deoxidation. , ntxiv qee qhov nyiaj ntawm silicon rau hlau tuaj yeem txhim kho lub zog, hardness thiab elasticity ntawm hlau.
