Ferrosiliconrau deoxidation yog adeoxidizerDav siv hauv kev tsim cov hlau. Ferrosilicon rau deoxidation feem ntau yog suav txog silicon (si) thiab hlau (mn), carbon, carbon (c), sulfur (s) thiab lwm yam ntsiab. Ntawm lawv, silicon yog lub ntsiab tseem ceeb rau deoxidation. Cov ntsiab lus silicon ntawm ib txwm ferrosilicon rau deoxidation feem ntau ntawm 45% thiab 75%. Cov uas muajFerrosilicon 65, ferrosilicon 70, ferrosilicon 72, thiabferrosilicon 75Cov. Ferrosilicon nrog cov ntsiab lus sib txawv silicon muaj kev cuam tshuam deoxidation sib txawv thiab cov xwm txheej siv tau.
Ua Haujlwm Cov Ntsiab Cai
Thaum lub sij hawm steel smatting txheej txheem, silicon muaj kev muaj zog muaj zog nrog oxygen. Cov silicon hauv ferrosilicon tuaj yeem hnov mob nrog cov pa hauv cov hlau molenten hauv cov hlau ua kom cov silicon dioxide (sitio₂). Cov tshuaj tiv thaiv cov tshuaj tiv thaiv yog: 2sk {1}} {{2} {sio₂.
Cov khoom lag luam silicon dioxide tuaj yeem txuas ntxiv nrog lwm cov neeg oxides hauv cov hlau tsis muaj me me los ua cov tshuaj pleev tsawg. Cov tshuaj no muaj cov kav hlau qis dua li cov hlau me me thiab yuav ntab saum npoo ntawm Molten Steel Deigidation thiab txhim kho qhov zoo thiab ua tau zoo ntawm cov hlau.
Khoom nta
Muaj zog deoxidation muaj peev xwm:
Ferrosilicon muaj lub siab deoxidation equiciency, tuaj yeem txo cov ntsiab lus oxygen hauv cov hlau, thiab txhim kho cov pa purity ntawm tus hlau.
Tus nqi qis: piv nrog qee tus deoxidizers, tus nqi tsim ntawm Ferrosilicon yog qhov tsawg, thiab nws muaj kev lag luam zoo hauv cov hlau.
Yooj yim siv:
Ferrosilicon feem ntau yog ua rau hauv cov block lossis granules, uas yooj yim rau cia, tsheb thauj mus los thiab ntxiv thaum lub sij hawm steelmaking. Qhov nyiaj ntxiv tuaj yeem tswj tau yog raws li cov cai ntawm cov hom steel thiab ntau lawm.
Daim Ntawv Thov Kev Thov
Converter steelmaking:
Nyob rau hauv cov theem tom qab ntawm converter blacking, ferrosilicon tau ntxiv rau cov hlau tsis sib xws hauv cov hlau tsis sib xws tau ua kom muaj pes tsawg tus qauv ntawm cov hlau tau raws cov qauv. Nyob rau tib lub sijhawm, Oxygen nyob rau hauv lub molten hlau raug tshem tawm kom tau zoo ntawm cov hlau.
Hluav taws xob tshuab cua kub:
Nyob rau hauv cov txheej txheem ntawm cov rauv taws ua kom loj dua qub, ferrosilicon tseem yog ib qho ntawm cov deoxidizers feem ntau. Ntxiv nws thaum lub sij hawm yaj thiab kho kom zoo dua txo cov txiaj ntsig oxygen hauv cov hlau, tshwj xeeb tshaj yog rau cov khoom lag luam zoo alloy hlau thiab stainless hlau.
Kev Lag Luam:
Nyob rau hauv cam khwb cia hlau ntau lawm, ferrosilicon tsis tuaj yeem siv los ua deoxidization, uas tuaj yeem txhim kho lub zog ntawm cov hlau thiab ua kom muaj zog, kev coj tsis kam ntawm cov hlau pov tseg.
