Mechanism
Cov tshuaj tiv thaiv deoxidation:
Si+2[O] → SiO2(s)
SiO₂ tsim cov txheej txheem slag cais lossis raug kaw hauv cov lim dej, tawm hauv cov hlau huv.
Nyob rau hauv tooj liab alloys, Si kuj ua raws li ib tugCov tshuaj tiv thaiv kom muaj zogthiab hloov kho eutectic qauv.
Qhov zoo
Nruab nrab Si cov ntsiab lus→ Siv yooj yim dua rau cov qib Si hauv cov hlau tsis muaj hlau.
Dual muaj nuj nqi(deoxidation + alloying) txuag cov txheej txheem.
Tus nqi qis duatshaj cov qib siab Si thaum lub siab Si tsis tas yuav tsum tau ua.
Zoo muajnyob rau hauv granular los yog crushed cov ntaub ntawv haum rau ladle los yog crucible ntxiv.
Kev txiav txim siab
FeSi70 qhiahlaumus rau hauv yaj, uas tej zaum yuav undesirable nyob rau hauv ib co high-purity non-ferrous alloys (xws li, hluav taws xob tooj liab). Yog li ntawd,ntshiab silicon hlauyog nyiam.
Cov ntsiab lus hlau yuav tsum raug suav rau hauv qhov kawg alloy chemistry suav.
Me me steel mills (feem ntaumini-mills, induction furnace khw, los yog me me BOF converters) tau txais txiaj ntsig los ntawmFeSi70 qhov sib npaug ntawm Si cov ntsiab lus thiab tus nqi, ua rau lawv sib tw kev lag luam thaum tswj tau qhov zoo.
Tus nqi-Cov xwm txheej zoo

Yog vim li cas FeSi70 Yog Tus Nqi -Qhov Zoo
|
|
|
|
Kev ua tiav yuav tsum tau Si (piv txwv li, 0.15-0.30%) nrog cov alloy tsawg dua FeSi65, tsis txhob oversized Fe ntxiv
|
Xam qhov tseeb Si xav tau; siv FeSi70 kom tsis txhob muaj kev sib tsoo ntau dhau
|
|
Zam kev ua kom siab-Si overspecification
|
FeSi75 tuaj yeem thawb Si dhau qhov xav tau, xav tau kev ntsuas kho
|
FeSi70 tso cai rau kev tswj kom zoo nyob ze ntawm qhov nruab nrab Si specs
|
|
|
pheej yig dua FeSi75; rau cov cua sov me me, tag nrho cov nqi alloy yog qhov qis dua
|
Yuav hauv ntau me me los yog hnab ntim khoom kom yooj yim tuav
|
|
|
Tsawg SiO₂ tsim ib chav tsev Si ntxiv → me me slag ntim, tsawg refractory hnav, txo nqi tu
|
Ua kom zoo ntxiv kom txo qis tom qab nchuav slag tshem tawm haujlwm
|
|
Cov khoom lag luam yooj yim
|
FeSi70 tuaj yeem ua haujlwm ob lub luag haujlwm (deoxidation hauv steel + inoculation hauv hlau), txo cov hom alloys khaws cia
|
Siv tib cov khoom siv rau ob txoj kev yog tias muaj
|
|
Kev noj tshuaj yooj yim dua
|
Granulated FeSi70 ntws zoo hauv phau ntawv me me lossis semi-automated feeders
|
Siv calibrated daus los yog me me hopper rau kev noj kom zoo ib yam
|
