Dab tsi yog Kev Siv Ferrosilicon?

(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 nyob rau hauv steelmaking rau nag lossis daus thiab diffusion. deoxidation. Ntxiv qee qhov nyiaj ntawm silicon rau hlau tuaj yeem txhim kho lub zog, hardness thiab elasticity ntawm hlau. Thaum muaj SiO.40-2.8 feem pua ​​) thiab silicon steel rau transformers (muaj 2.81-4.8 feem pua ​​silicon), ferrosilicon kuj yog siv los ua tus neeg sawv cev alloying. Nyob rau tib lub sijhawm, kev txhim kho cov duab ntawm kev suav nrog thiab txo cov ntsiab lus ntawm cov khoom siv roj hauv cov hlau molten yog cov cuab yeej tshiab zoo los txhim kho steel zoo, txo cov nqi thiab txuag hlau. Nws yog tshwj xeeb tshaj yog haum rau deoxidation yuav tsum tau ntawm nruam casting molten steel. Kev xyaum tau ua pov thawj tias ferrosilicon tsis yog tsuas yog ua tau raws li qhov yuav tsum tau ua ntawm deoxidation ntawm steelmaking, tab sis kuj muaj desulfurization kev ua tau zoo thiab muaj qhov zoo ntawm lub ntiajteb txawj nqus loj thiab muaj zog nkag.

Tsis tas li ntawd, nyob rau hauv kev lag luam steelmaking, ferrosilicon hmoov tuaj yeem tso tawm ntau cov cua sov ntawm qhov kub thiab txias, thiab nws 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.

(2) Siv los ua inoculant thiab tus neeg sawv cev nodularizing 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, thiab muaj cov khoom zoo tshaj plaws thiab kev poob siab zoo dua li cov hlau. Tshwj xeeb, cov hlau nplaum, nws cov khoom siv kho tshuab yog nyob ntawm lossis ze rau cov hlau. Ntxiv ib qho nyiaj ntawm ferrosilicon rau cam khwb cia hlau tuaj yeem tiv thaiv kev tsim cov carbides hauv 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 ua tus neeg sawv cev txo qis hauv kev tsim cov ferroalloys. Tsis tsuas yog cov tshuaj affinity ntawm silicon thiab oxygen yog siab heev, tab sis kuj cov pa roj carbon ntsiab lus ntawm siab silicon ferrosilicon yog tsawg heev. Yog li ntawd, high-silicon ferrosilicon (los yog siliceous alloy) yog ib qho uas feem ntau siv los txo tus neeg sawv cev hauv kev tsim cov pa roj carbon monoxide qis hauv kev lag luam ferroalloy.

(4) 75 # ferrosilicon feem ntau yog siv rau hauv cov txheej txheem kub kub ntawm cov hlau magnesium hauv Pidgeon txheej txheem ntawm magnesium smelting. Cov magnesium nyob rau hauv CaO.MgO yog hloov, thiab li ntawm 1.2 tons ntawm ferrosilicon yog noj rau txhua tuj ntawm hlau magnesium tsim. Nws ua lub luag haujlwm zoo hauv kev tsim cov hlau magnesium.

(5) Siv rau lwm yam. Hauv av los yog atomized ferrosilicon hmoov tuaj yeem siv los ua ib theem 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 tsim cov khoom xws li silicone.

Ntawm cov kev siv no, kev lag luam steelmaking, kev lag luam foundry thiab kev lag luam ferroalloy yog cov neeg siv ntau tshaj plaws ntawm ferrosilicon. Ua ke, lawv haus txog 90 feem pua ​​​​ntau dua ferrosilicon. Ntawm ntau qib ntawm ferrosilicon, 75 feem pua ​​​​ferrosilicon yog tam sim no siv dav tshaj plaws. Hauv kev lag luam steelmaking, kwv yees li 3-5kg ntawm 75 feem pua ​​​​ferrosilicon tau noj rau txhua 1t ntawm cov hlau tsim.
