Silicon-Barium (Si-BA) Alloy yog siv tau ua tus deoxidizing thiab desulfurizing hauv steelmaking thiab raws li ib qho inoculant hauv casting. Kev npaj ntawm Si-BA allooy feem ntau cuam tshuam los ntawm carbothermal txo qis aluminoticmic txo nyob rau hauv lub cub hluav taws los yog tog arc rauv. Cov txheej txheem tseem ceeb yog raws li hauv qab no:
1. Carbothermal txo cov qauv
Qhov no yog qhov kev siv ntau tshaj plaws rau kev tsim cov khoom silicon-barium alloy. Cov txheej txheem cuam tshuam kev txo cov zaub mov barium-muaj cov minerals (xws li neto bas) thiab silica (sitio₂) nrog cov pa roj carbon kub.
Cov kev sib npaug:
Biso 4+4 C → B}}}}}}}}}}}} C} {}} co} Bas + {2+2 C → Basi {9}}}}}}}} C {} {16}}}
Cov kauj ruam kauj ruam:
Cov Khoom Siv Khoom Raw:Sib tov cov chaw yug (Biso₄), Quartz (sitoo₂), thiab Coke (C) hauv cov feem ntau.
SMELTING:Cov sib tov yog pub rau hauv lub tshuab hluav taws xob ua kom sov1400-1600 Qib, qhov twg txo cov tshuaj tiv thaiv tshwm sim.
Alloy sib cais:Lub Molten Si-BA alloy tau sib cais los ntawm slag thiab impurities.
Casting thiab txias:Lub alloy tau raug pov rau hauv kev mus rau hauv kev mus ua ntej tsoo mus rau hauv cov loj me me.
2. Alleothermic Txo Txoj Kev
Hom no siv cov txhuas (al) raws li tus neeg sawv cev txo tus neeg sawv cev siv carbon. Nws yog feem ntau siv rau kev coj siab-purity yog ntau lawm.
Cov kev sib npaug:
3bao +2 al → 3ba + al {}} {} {} {} {} {} {{}
Cov kauj ruam kauj ruam:
Nws:Lub npe (Bao), sila), silicon dioxide (sitio₂), thiab txhuas hmoov tau sib xyaw ua ke hauv kev piv txwv.
Neej taws:Qhov sib tov yog taws thaum kub (~ 2000 degree) los ua rau muaj kev cuam tshuam zoo heev.
Sib cais:Lub BaClot BA-Si Alloy cais tawm ntawm Aluminium Oxide (Al₂o₃) Slag.
Cua txias & Kev Ua:Cov txheej txheem sib luag yog tsoo rau hauv granules los yog hmoov raws li xav tau.
3. Electrolytic txo cov qauv (tsawg dua)
Koom nrog cov electrolysis ntawm cov ntsev ntsev thiab silica hauv molten electrolytes.
High-purity Si-BA alloys tuaj yeem tau txais, tab sis cov qauv no raug nqi thiab tsis tshua siv hauv kev siv cov ntawv thov.
