Silicon-Barium (Si-BA) alloy yog ib qho tseem ceeb me me me me ntawm statoldical thiab cam khwb cia vim nws zoo deoxidation, thiab inoculation tej yam.
1. Tshuaj lom neeg sib xyaw
SI-BA alloys feem ntau muaj sib txawv ntawmsilicon (si)thiabbarium (ba), nrog cov nyiaj me meCalcium (Ca), Aluminium (Al), thiab Hlau (Fe)raws li impurities. Cov muaj feem sib xyaw muaj xws li:
| Teem nqi | SI (%) | BA (%) | CA (%) | Al (%) | FE (%) |
|---|---|---|---|---|---|
| Si50BA30 | 50 | 30 | Tsawg dua los yog sib npaug rau 2. 0 | Tsawg dua los yog sib npaug rau 2. 0 | Tsawg dua los yog sib npaug rau 3. 0 |
| CasceBA15 | 60 | 15 | Tsawg dua los yog sib npaug rau 2.5 | Tsawg dua los yog sib npaug rau 2.5 | Tsawg dua los yog sib npaug rau 3.5 |
| SI65BA10 | 65 | 10 | Tsawg dua los yog sib npaug rau 3. 0 | Tsawg dua los yog sib npaug rau 3. 0 | Tsawg dua los yog sib luag rau 4. 0 |
2. Lub zog lub cev
Zog:Metallic Grey lossis Nyiaj-Dawb Khoom
Ntawj ntom:3. {{0 - - 4.5 g / cm³ (sib txawv nrog kev sib xyaw)
Melting taw tes:1100-1350 Qib (nyob ntawm SI / BA piv)
Hardness:Raug nkawv
3. Tshuaj lom neeg
Muaj peev xwm deoxidizing muaj peev xwm:Barium muaj kev muaj zog rau oxygen dua li silicon, txhim kho cov alloy lub deagidizing efficiency.
Cov nyhuv desulfurization:Si-BA npaj kom tau zoo li leej faj los ntawm Molten Steel, txo kev impurities.
Txo slag viscosity:Lub Alloy txhim kho fellity nyob rau hauv cov hlau ua kom ua tiav cov txheej txheem.
Reflective nrog noo noo:Barium reacts nrog dej los tsim hydrogen roj, yog li cov alloys yuav tsum muab cia rau hauv cov chaw qhuav.
