Nyob rau hauv high - Cov teb kub me me xws li cov hlau thiab cov khoom siv,FERRO Silicontau siv rau ntau xyoo raws li ib txwm muajdeoxidizerthiab cov neeg sawv cev sib dhos. Txawm li cas los xij, nrog nce ib puag ncig lub zog thiab kev tsim kho tshiab hauv cov cuab yeej siv thev naus laus zis,Silicon Carbide (Sic)yog maj mam ua txoj kev xaiv zoo tagnrho rau ferrosilicon vim nws qhov kev ua haujlwm siab thiab cov pa tsis tshua muaj.
Kev sib piv sib piv ntawm silicon carbide thiab ferrosilicon: vim li cas nws thiaj li hloov tau?
Silicon carbide (tshuaj lom neeg sic) yog ib qho kev sib cav sib ceg siv lead ua ke ntawm silicon thiab carbon. Piv rau ferrosilicon (FESI alloy muaj 75% -90% silicon), nws lub cev muaj tshuaj lom neeg yog qhov tsim nyog rau cov khoom siv metallurgical niaj hnub:
Deoxidation efficiency:
Silicon carbide muaj cov ntsiab lus silicon ntawm ntau tshaj 90%, thiab cov carbon lub caij nyoog tuaj yeem syroxidize. Nws lub deoxidation efficiency hauv Molten Steel yog 15% -20% siab dua li ntawm ferrosenicon, txo cov ntsiab lus pa oxygen hauv qab 0.002%.
Tus phooj ywg zoo:
Cov txheej txheem ferrosilicon kwv yees li 8 tons ntawm kev sib xyaw ua ke rau ntau dua 5 tons ntawm cov txheej txheem ua kom zoo dua, ua rau nws ua kom zoo dua nrog cov "ob txoj cai ntawm cov roj carbon".
Tus nqi ua nqi kom zoo dua:
Txawm hais tias silicon carbide yog kim dua ferrosilicon, nws txo cov khoom siv deoxidation los ntawm 30%, txo cov nqi hlau tag nrho los ntawm 5-8 Yuan ib tuj.
Kob Txom Nyem Tswj:
Cov tub qhe Sulphur thiab phosphorus cov ntsiab lus hauv Silicon Carbide yog tsawg dua lossis sib npaug ntawm cov ferrosilicon (feem ntau tsawg dua lossis sib npaug ntawm cov khoom muaj teeb meem hauv cov hlau.
Core Apper Scararios Rau Silicon Carbide Hloov Ferrosilicon
1. Cov pa roj carbon hlau dawb thiab qis {-} alloy alloy alleoy steel smelting: muaj txiaj ntsig deoxidation thiab desulfurization
Nyob rau hauv Converter thiab Fais Arc rauv taws ua kom loj, silicon carbide tuaj yeem hloov ferro silicon alloy rau ob qho Pre {{deoxidation thiab deoxidation kawg.
Hloov piv:
Feem ntau tau xam ntawm qhov sib piv ntawm 1: 1.2-1.5 (1 tuj ntawm silicon carbide alloy tuaj yeem hloov 1.2-1.5 tons ntawm75% ferrosilicon).
Cov lus thov thov:
Ib pab pawg steel tau ua rau pom tias siv cov ntsiab lus sic txo cov pa roj kawg ntawm 0.0025% rau 0.0028% rau 0.0028% rau 0.0028%, thiab cov subcutaneous porcase qhov tsis taus
Cov Hlau Hlau:
Cov hlau nplaum cov hlau xws li Q235 thiab 45 # STEEL, nrog rau qhov qis-} inelo alcegs xws li 20cr.
2. Foundry Kev Lag Luam: Txhim Kho Hlau qauv thiab Flowability
Hauv kev tsim cov grey thiab canbide, silicon carbide tuaj yeem hloov ferrosilicon ua ib qho kev ua kom zoo nkauj, muaj ntau yam zoo:
Lis Kev Txhim Kho:
Cov pa roj carbon hauv silicon carbide txhawb nqa graphite nucleation graphite nucleation cov ntsiab lus ntawm cam khwb cia cov ntsiab lus los ntawm kev cam khwb cia hlau los ntawm 10% thiab txhim kho hardness los ntawm HB15-20.
Txhim kho Flowability:
Nyob rau hauv audotive lub tog raj kheej thaiv, kev siv cov silicon carbide txhim kho molten hlau wurgeility los ntawm 88% mus rau 95%.
Txo shrinkage:
Txo cov hlau cam khwb cia hauv qab no 0.8%, txo qis shrinkage kab noj hniav thiab porosity.
3. Ferrinoalloy kev tsim khoom: Txo kev siv hluav taws xob thiab kev cuam tshuam
Hauv kev tsim cov silicon manganese alloys thiabcalcium silicon alloys, silicon carbide tuaj yeem hloov cov ferrosilicon raws li kev pab txhawb silicon ntxiv.
Txuag txuag:
Siv 300kg ntawm silicon carbide es tsis txhob ferrosilicon ib tuj ntawm simn alloy tuaj yeem txo cov hluav taws xob tau los ntawm kwv yees li 150kWh. Kev Ua Kom Zoo Dua: Txo cov hlau hlau hauv alloys (los ntawm 2% -3% rau 1% -1.5%), txhim kho cov khoom siv kev ua suab paj nruag.
4. Cov Hlau Tshwj Xeeb SMELTING: Kev Tswj Xyuas Kev Tiv Thaiv
Hauv kev tsim cov siab - {{{{1} {{{1} {{{1} {{{1 {1} {carbide lub zog yog qhov tseem ceeb:
Stainless hlau (piv txwv li, 304 thiab 316):
Hloov Ferrosilicon zam dhau ntawm cov hlau uas muaj hlau loj dhau ntawm cov hlau sib xyaw ua ke thiab txo tom qab De {{}} tus nqi hlauization.
Thaum tshav kub kub - tsis kam hlau (xws li, cr25ni20):
Silicon Carbide lub peev xwm ruaj khov kho lub peev xwm txo cov roj av thiab txhim kho siab {}} oxidation tsis kam.
Hloov cov ferrosilicon nrog silicon carbide tsis yog tsuas yog kev xaiv rau kev lag luam metej, siab - kev ua tau zoo. Los ntawm cov pa roj carbon hlau rau cov me nyuam tshwj xeeb, nws cov ntawv thov nthuav dav, nqa ntau cov txiaj ntsig rau kev txo nqi them, kev txhim kho kom zoo dua qub, thiab emission txo. Nrog kev vam meej ntawm kev siv thev naus laus zis thiab kev txhawb nqa txoj cai, silicon carmide kev xaiv ua cov khoom siv metallugical nyob rau hauv lub xyoo tom ntej 5-10 xyoo, tsav lub lag luam kev hloov pauv ntsuab. Yog tias koj xav paub txog cov kev daws teeb meem lossis kev yuav pom zoo rau kev lag luam, koj tuaj yeem tiv tauj peb kom tau txais daim ntawv tshaj tawm tshawb xyuas.
