Xi'an Huachan moollurgical Technical Technology Co {}}, ltf} Yog cov khoom siv hluav taws xob, xws li cov khoom siv hluav taws xob ua haujlwm, xws li kev siv hluav taws xob ntawm hluav taws xob (LF) Cov tshuab hluav taws xob, thiab submerged arc rauv (kev nyab xeeb).
Kev noj electrode yog ib qho ntawm cov kev ua haujlwm tseem ceeb tshaj plaws hauv cov nqi hluav taws xob hauv hluav taws xob rauv (EAF Steel Ua) {{. electrodes account rau5-15% ntawm tag nrho cov nqi tsim khoom, ua rau lawv siv tau cov nqi tseem ceeb {}}
Kab lus no muab cov kev tsom xam ntawm cov electrode hauv EAFS, npog:
✔ Cov Nqi Kev Lag Luam
Cov ntsiab lus tseem ceeb uas cuam tshuam rau hluav taws xob hnav
✔ Cov tswv yim los txo cov chaw siv electrode
✔ Cov ntaub ntawv sib piv hla lub cub tawg
Kev Siv Electrode: Kev Tshawb Fawb Cov Qauv
Kev Siv Nqi
| Hom rauv | Kev noj electrode (kg / Tuj Hlau) |
|---|---|
| Cov pa AC EAF | 1.8 – 3.5 |
| Ultra-Siab Fais Fab (UHP) EAF | 1.2 – 2.5 |

Vim li cas cov electrodes tau noj?
- Ntsis oxidation (40-60% ntawm kev poob)
Cov tshuaj tiv thaiv nrog oxygen ntawm 3,500℃arc tsam:
C + O₂ → KOM
- Kev ntsuas kev ntsuas Oxidation (20-30%)
Huab cua / ua npuas ncauj tawg ntawm qib da dej
- Neeg kho tshuab tawg (10-20%)
Kev sib tsoo nrog seem, electrode slips
- Lub txiv mis sib koom ua ke (5-15%)
Xov hnav thaum muaj electrode kem kev
