Silicon Carbide 85/75Cov nplej tuaj yeem pab EAF steelmakers txhim kho kev tswj hwm tus nqi los ntawm kev sib txuas peb lub luag haujlwm hauv ib qho khoom siv: deoxidation, silicon- carbon ntxiv thiab tso tawm cua sov.Nyob rau hauv qhov tsim nyog rau cov cua sov, SiC nplej tuaj yeem hloov cov tshuaj deoxidizers xws li ferrosilicon thaum tseem ua rau cov pa roj carbon thiab tshuaj kub rau cov da dej molten. Qhov txiaj ntsig tiag tiag tsis yog "kev siv hluav taws xob qis dua," tab sis zoo dua tag nrho cov nqi hluav taws xob thaum qib SiC, qhov loj me me, ntxiv sijhawm ntxiv thiab tus nqi rov qab tswj tau zoo.
Rau EAF cov nroj tsuag ntsib cov nqi hluav taws xob siab, cov nqi hlau alloy siab thiab nruj zog ntau lawm,Silicon Carbide 85 nplejthiabSilicon Carbide 75 nplejyog tsim nyog ntsuas raws li cov tswv yim metallurgical additives.
Vim li cas EAF Steelmakers Care Txog SiC Grains
Hluav taws xob arc rauv steelmaking yog rhiab rau lub zog nqi, coj mus rhaub - mus rau - coj mus rhaub lub sij hawm thiab alloy rov qab. Txawm tias cov txheej txheem me me tuaj yeem cuam tshuam cov nqi tsim khoom thaum lawv rov qab hla ntau qhov cua sov.
Kev xyaum steelmaking tej zaum yuav siv cais cov ntaub ntawv rau deoxidation, silicon ntxiv thiab hloov carbon. Qhov no ua haujlwm, tab sis nws tuaj yeem nce cov khoom tuav cov kauj ruam thiab cov nqi alloy.Silicon carbide nplejmuaj txiaj ntsig vim tias lawv muab ob qho tib si silicon thiab carbon nyob rau hauv ib qho khoom thaum tseem tso cua sov thaum cov tshuaj tiv thaiv.
Qhov no ua rau SiC nplej sib txawv ntawm ib qho - ua haujlwm ntxiv. Lawv tuaj yeem txhawb nqa:
- tshem tawm cov pa oxygen hauv molten steel;
- silicon thiab carbon input;
- cub hluav taws xob tshuav nyiaj li cas;
- ib nrab txo ntawm ferrosilicon dependence;
- yooj yooj yim raw khoom nqi tswj.
Txawm li cas los xij, SiC yuav tsum tsis txhob raug kho raws li kev hloov pauv thoob ntiaj teb rau ferrosilicon lossis recarburizer. Qhov tshwm sim tiag tiag nyob ntawm kev xyaum ua kom sov, qib steel, kev ua haujlwm oxygen, cov hom phiaj carbon, slag mob thiab cov txheej txheem ntxiv.
Yuav ua li cas Exothermic Reaction ntawm SiC Pab EAF Kev Ua Haujlwm
Lub ntsiab yog vim li cas steelmakers tham txog SiC nyob rau hauv kev sib raug zoo rau cov nqi hluav taws xob yog nws tus cwj pwm exothermic. Thaum lub sij hawm siab -kub steelmaking, silicon carbide tuaj yeem koom nrog cov tshuaj tiv thaiv uas tso tawm cua sov thiab txhawb nqa deoxidation.
Rau cov neeg ua haujlwm EAF, qhov no yog qhov tseem ceeb vim tias ib feem ntawm cov nqi hluav taws xob txuas nrog lub zog hluav taws xob ntau npaum li cas kom ncav cuag thiab tswj qhov kub ntawm chav da dej. Yog tias cov khoom siv ntxiv tuaj yeem ua rau muaj tshuaj lom neeg thaum tseem ua haujlwm metallurgical, nws tuaj yeem pab txhim kho tag nrho lub zog sib npaug.
Lub ntsiab lus tseem ceeb yog qhov no:
SiC nplej tsis "hloov hluav taws xob" ncaj qha. Lawv txhawb lub cub tawg los ntawm kev ntxiv tshuaj lom neeg lub zog thaum cov tshuaj tiv thaiv.
Qhov no yog vim li cas qhov txiaj ntsig yuav tsum raug ntsuas los ntawm tag nrho cov khoom siv hluav taws xob, tsis yog los ntawm cov khoom siv tus nqi ib leeg. Ib tsob nroj yuav tsum sib piv:
- kev siv hluav taws xob ib qho cua sov;
- ferrosilicon noj;
- noj recarburizer;
- deoxidation stability;
- silicon thiab carbon rov qab;
- coj mus rhaub-rau- coj mus rhaub lub sij hawm;
- tag nrho cov nqi ib ton ntawm steel.
Vim li cas SiC 85 thiab SiC 75 siv txawv
Silicon Carbide 85 nplejfeem ntau yog xaiv thaum cov nroj tsuag xav tau ntau dua SiC cov tswv yim thiab muaj zog deoxidation kev ua tau zoo. Nrog rau cov ntsiab lus SiC siab dua, qib no yog qhov tsim nyog rau cov neeg yuav khoom uas tsom mus rau kev ruaj khov thiab ua kom sov.
Silicon Carbide 75 nplejfeem ntau xaiv thaum tus neeg yuav khoom xav tau qhov sib npaug zoo ntawm kev ua tau zoo thiab tus nqi. Tej zaum nws yuav tsim nyog rau kev siv EAF deoxidation, cov nqi hluav taws xob thiab tus nqi -sensitive steelmaking daim ntaub ntawv.
Qhov kev xaiv tsis yog tsuas yog "85% zoo dua 75%. Kev xaiv siv tau ntau dua nyob ntawm seb cov txheej txheem rhiab npaum li cas rau SiC cov ntsiab lus, cov pa roj carbon monoxide, Fe₂O₃, noo noo thiab particle loj.
Piv txwv li, cov nroj tsuag tsim cov qib steel nruj dua yuav nyiam SiC 85 vim tias muaj cov ntsiab lus siab dua. Ib tsob nroj feem ntau tab tom nrhiav rau tus nqi - silicon zoo- cov pa roj carbon monoxide yuav xaiv SiC 75 yog tias qhov cua sov tso cai rau nws.
Particle loj cuam tshuam rau cov tshuaj tiv thaiv thiab hluav taws xob nqi logic
Hauv EAF steelmaking, particle loj ncaj qha cuam tshuam li cas SiC nkag mus rau hauv da dej, nws sai npaum li cas thiab poob ntau npaum li cas thaum pub mis.
Cov hmoov zoo yuav hnov mob sai, tab sis nws kuj tuaj yeem tsim cov plua plav poob thiab daws teeb meem. Cov pob loj loj tuaj yeem txo cov plua plav, tab sis lawv yuav yaj qeeb dua. Vim li no, ntau EAF cov neeg yuav khoom nyiam tswjsilicon carbide nplejes tsis txhob random sib xyaw - cov khoom loj.
Cov kev xaiv uas muaj xws li:
| Particle Loj | Hom kev siv | Main Advantage |
|---|---|---|
| 1-5 hli | Cov tshuaj tiv thaiv sai, ladle lossis refining siv | Kev sib cuag zoo dua nrog cov hlau molten |
| 0-10 hli | General EAF deoxidation | Sib npaug tshuaj tiv thaiv thiab pub mis |
| 10-50 hli | Rauv nqi | Tsawg plua plav poob thiab yooj yim tuav |
Yog tias lub hom phiaj yog txhawm rau txhim kho EAF tus nqi kom zoo, qhov loj me yuav tsum raug xaiv raws li kev pub mis thiab lub sijhawm tshuaj tiv thaiv. Ib qib SiC uas tsim nyog nrog qhov loj me me tuaj yeem ua haujlwm tsis zoo.

Real Production Logic: Qhov Chaw Txuag Los Ntawm
Thaum siv cov nroj tsuag steelSilicon Carbide 85/75 nplej, cov txiaj ntsig kev lag luam tuaj yeem los ntawm ntau qhov kev qhia.
Ua ntej, SiC tuaj yeem txo qis ib feem ntawm kev vam khom ntawm ferrosilicon thaum cov txheej txheem tso cai hloov ib feem. Qhov no yog qhov tshwj xeeb tshaj yog thaum ferrosilicon cov nqi siab lossis cov khoom tsis ruaj khov.
Thib ob, SiC muab cov pa roj carbon zoo li silicon. Hauv qee qhov kev coj ua rau lub cub tawg, qhov no tuaj yeem yooj yim ib feem ntawm cov khoom siv ntxiv.
Thib peb, cov tshuaj tiv thaiv exothermic ntawm SiC tuaj yeem txhawb kev sib npaug ntawm cov cua sov. Yog tias cov nroj tsuag tuaj yeem siv cov cua sov no kom zoo, nws tuaj yeem pab txo qis cov khoom siv hluav taws xob uas tsis tsim nyog lossis txhim kho cov khoom sib dhos.
Plaub, cov nplej tswj tau tuaj yeem txo cov plua plav poob piv nrog cov hmoov-zoo li cov khoom siv. Ntau cov khoom nkag mus rau hauv lub qhov cub txhais tau hais tias kev siv cov khoom siv raw zoo dua.
Qhov kawg tshwm sim tsis yog hais txog cov nqi hluav taws xob qis xwb. Nws yog hais txog kev txo qis qhov poob thoob plaws deoxidation, alloy ntxiv, tuav cov khoom thiab lub sijhawm ua kom sov.
Piv txwv Scenario: EAF Cog Facing High Alloy thiab Energy Costs
Ib tsob nroj EAF raug siv ferrosilicon rau deoxidation thiab cais cov khoom siv rau kev hloov kho. Thaum cov nqi hluav taws xob thiab cov nqi alloy nce tib lub sijhawm, cov nroj tsuag pib nrhiav cov khoom siv uas tuaj yeem muab ntau dua ib qho kev ua haujlwm.
Hauv qhov xwm txheej no, SiC 85 nplej tuaj yeem raug sim ua qhov siab dua - nquag silicon-carbon additive. Yog tias qhov cub ua haujlwm txhawb nqa nws, ib feem ntawm ferrosilicon tuaj yeem hloov pauv thaum SiC tseem txhawb nqa cov pa roj carbon thiab cov tshuaj tiv thaiv tshav kub.
Rau cov cua sov tsawg dua lossis cov nqi ntau dua -sensitive ntau lawm, SiC 75 nplej yuav raug kuaj kom sib npaug deoxidation kev ua tau zoo thiab cov nqi khoom.
Cov txiaj ntsig tau tshwm sim feem ntau yog ntsuas los ntawm cov ntaub ntawv siv hluav taws xob: cov nyiaj ntxiv, tus nqi rov qab, qhov kawg steel muaj pes tsawg leeg, tus cwj pwm kub, slag mob thiab tus nqi hluav taws xob. Nov yog txoj hauv kev los txiav txim tus nqi SiC.
Cov neeg yuav khoom yuav tsum kuaj xyuas ua ntej siv SiC hauv EAF
Ua ntej yuav khoomSilicon Carbide 85/75 nplej, cov neeg yuav khoom yuav tsum paub meej ntau dua li SiC feem pua.
Cov ntsuas tseem ceeb suav nrog:
- SiC cov ntsiab lus;
- dawb carbon;
- Fe₂O₃;
- noo noo;
- sulfur thiab phosphorus yog tias xav tau;
- particle loj faib;
- hmoov av / nplua cov ntsiab lus;
- packing mob;
- batch COA;
- kev sim ua kom sov ua haujlwm.
Kev hais lus qis yuav tsis txo qis tus nqi hluav taws xob yog tias cov khoom siv tsis ruaj khov, cov dej noo siab lossis kev tswj tsis zoo particle loj. Rau kev siv EAF, qhov sib xws yog qhov tseem ceeb tshaj qhov sib txawv ntawm tus nqi me me.
