Yam xwm txheej dab tsi txiav txim siab xaiv cov graphite electrodes rau EAF thiab LF Furnaces?
Ntau qhov sib cuam tshuam Qhia txog kev xaiv qhov kev xaiv qhov ua tau zoo thiab raug nqi {{}} efficiency:
Rauv Zog thiab Kev Ntsuas Tam Sim No: Larger EAFs (100–300 tons) with higher power (100–200 MVA) require UHP electrodes (ampacity >60 Ka) Los lis cov dej siab. Me EAFs lossis LFS (50-100 tons) tuaj yeem siv siab- power (30-50 ka).
Qib qib hlau thiab qib yuav tsum muaj: Ua Siab Loj - Zoo Hlau (piv txwv li, Automotive, Aerospace) Xav Tau Tsawg- tshauv (<0.3%), low-sulfur (<0.05%) electrodes to avoid contaminating molten metal. Lower-grade steels (e.g., construction rebar) may tolerate Regular-Power (RP) electrodes with slightly higher impurities.
Kev coj ua haujlwm: Nquag kais - rau -} Nrhiav cov hluav taws xob (kev nyiam hluav taws xob nrog lub zog thermal tsis kam. LFS nrog cov cua sov siab dua (20-40 feeb) ua ntej oxidation tsis kam.
Tus nqi vs. Kev Lag Luam Nyiaj Txiag: UHP cov electrodes yog 20-30% kim dua li RP tab sis xyoo 50-100% ntev dua hauv EAF, txo qis qis. Rau LFS, HP cov hluav taws xob feem ntau sib npaug nqi thiab ntev dua vim yog qeeb qeeb tus nqi.
Ib puag ncig thiab kev nyab xeeb qauv: Kev tswj hwm cov kev tswj hwm yuav xav tau cov hluav taws xob nrog cov khoom siv volatents uas tsis muaj suab paj nruag (piv txwv li, cov khoom siv hluav taws xob) kom txo cov pa phem.
