Deagidation yog lub neej ntawm kev siab - Zoo steel ntau lawm. Tshaj tawm cov pa oxygen nyob rau hauv Molten Steel formal brittle oxide suav, uas muaj zog tensile lub zog, thiab nce cov nqi sib nraus, thiab nce cov nqi sib nraus. Rau cov mills steel, xaiv nruab nrab ntawmferrosiliconthiabSilicon Carbide (Sic)Raws li deoxidizers ncaj qha cuam tshuam cuam ntau dua, khoom zoo, thiab tag nrho cov nqi.
Ob cov ntaub ntawv tshem tawm oxygen los ntawm reacting nrog reacting los ntawm molten paths, tab sis lawv cov tshuaj tiv thaiv sib txawv tseem ceeb {} tso lub hauv paus rau lawv qhov kev ua tau zoo.
- ferrosilicon:Raws li cov duab nag los nag dag deasipition deas, fesi (feem ntau72%-75%Si Cov Ntsiab Lus) Kev Ntseeg Rau Silicon lub zog muaj kev sib txawv rau cov pa oxygen. Nws reacts sai rau tsim cov sio₂ suav, uas ntab rau lub ntsej muag swb vim lawv cov ntom ntom. Qhov no "kev sib cais sai sai + txheej txheem ua rau nws yog cov kab ntau heev.
- cua silicon carbide:Silicon carbide (ntau dua lossis sib npaug nrog 88% SIC Cov silicon ces deoxidizes kom ua cov sio₂, thaum cov pa carbon cov ntawv co roj uas tsis muaj kev phom sij. Qhov no "dual - kev ua" mechanism tseem muaj cov txiaj ntsig carbon, tshem tawm cov kev xav tau ntawm cov pa roj carbon ntxiv.
Lub taub hau - rau -} taub hau sib piv: kev ua tau zoo, zoo
Steel mills ua ntej peb cov kev ntsuas: kev ua haujlwm deoxidation thiab kev ua kom loj. Hauv qab no yog cov kev sib piv ntawm ob cov khoom siv:

Ferrosilicon alloy:Dominates nyob rau hauv ceev. Hauv kev sim siab nrog 30mnsi qauv steel, ntxiv 3-5 kg / t ntawm 72% ferrosilicon txo cov ntsiab lus ntawm 800 polm mus rau 50 ppm hauv 5 feeb. Qhov no luv lub sij hawm reduction lub sij hawm los ntawm 10-15% piv rau carbide silicon, nce cov cua sov txhua hnub los ntawm 2-3%.
Silicon Carbide:Kev tawm tsam me ntsis, tab sis nws exothermic decomposition tsim ib qho "ua npuas dej swb" txheej uas tsis ua haujlwm ntawm lub cev, txo cov cua sov los ntawm 8%. Rau hluav taws xob arc rauv (EAF), lub zog-txuag kom zoo muab tso rau cov khoom tso rau 50% ntawm lub sijhawm sib txawv.
