Dab tsi yog qhov tseem ceeb tshaj lij ntawm RP, HP, thiab UHP cov qib ntawm EAF Graphite electrodes?
Kev ua yeeb yam sib txawv ntawm RP, HP, thiab UHP graphite electrodes stems los ntawm lawv cov khoom muaj hluav taws xob thiab kev tsim kho hluav taws xob ncaj qha, cua sov, thiab cov khoom siv tshuab hluav taws xob:
Resistivity:RP electrodes muaj qhov siab tshaj tawm (~ 65-75 · M), ua rau kom muaj zog ntau dua li thaum muaj zog. HP cov ntaub ntawv hluav taws xob txo qhov no mus ~ 55-6 μω · M, txo cov khib nyiab. UHP electrodes ua tiav qhov qis tshaj resistivity (<55 μΩ·m), maximizing current efficiency and reducing power consumption.
Bulk ntom: Higher density enhances thermal conductivity and mechanical stability. RP electrodes (~1.68–1.70 g/cm³) are less dense, making them prone to oxidation and breakage. HP (~1.70–1.72 g/cm³) and UHP (>1.72 G /M³) Electrodes Siv Denser graphite, txhim kho kom muaj kev ntxhov siab thiab lub neej pabcuam ntev.
Lub zog Faj: Critical for withstanding mechanical stress during insertion/removal and high-temperature expansion. RP electrodes (~7 MPa) are weaker, while HP (~8 MPa) and UHP (>10 MPA) electrodes muaj lub zog zoo dua, txo qis kev phom sij hauv EAF loj.
Particle Loj & Purity:UHP Electrodes Siv cov khoom me me graphite (<15 μm) and lower impurity levels (e.g., sulfur <0.05%), ensuring tighter microstructures and consistent performance. HP and RP electrodes allow slightly coarser particles, balancing cost and performance.
