EAF Graphite Electrode

 

Internationally standardized diameters (e.g., UHP, HP, RP grades) typically range as follows:

Cov Hluav Taws Xob Me Me: 75mm ~ 300mm (rau lab-teev lossis EAF me)

Nruab Nruab Nruab Nruab Nruab Nrab: 350mm ~ 500mm (feem ntau tshwm sim hauv cov khoom siv hlau loj)

Cov Hluav Taws Xob Loj: 550mm ~ 800mm (rau Ultra-High-High-Power lossis Ntxiv-EAF)

Kev siv tam sim no	Rau txhua 10ka nce ntxiv, hluav taws xob diam yuav tsum nce los ntawm ~ 50 hli (kom tsis txhob muaj kev kub siab).
Cov txheej txheem yuav tsum tau ua	High-oxygen kev txhaj tshuaj cov txheej txheem xav tau cov kab mob loj dua kom tawm tsam oxidation .
Sib Koom Tes Muaj Zog	Diametters ntau dua los yog sib npaug rau 500mm yuav tsum tau xov tshwj xeeb xov (e ., npt {}}}

Cov Ntawv Thov:

Lab-teev cov nplai ua kom sov (tsawg dua los yog sib npaug rau 1 tuj)

Tshwj xeeb alloy refining (e {. g}.}, ti, v micro-kho)

Qhov Zoo:

Kev hloov pauv siab rau cov txheej txheem hloov

Tsawg dua kev nqis peev

Kev Kawm Txog:
Ib lub koom haum tshawb fawb tau siv 200Mm electrodes rau cov kev ua kom siab-dawb huv Alloy smelting, ua kom ceev tam sim no hauv qab 25a / cm².

Kev khiav hauj lwm tsis muaj:

Tam sim no: 40 ~ 80ka

Kev siv tus nqi: 1.8 ~ 2.5kg / tuj steel

Kev Kawm Txog:
Ib lub zeb siv 450 hli UHP Electrodes txo cov hluav taws xob rau 380kWh / tuj thiab cawm tau cov nqi electrode {}}

(3) Electrodes loj (550-800 mm)

Cov Ntawv Thov:

Cov hluav taws xob xaiv yog akev txiav txim siab loj heevRau EAF steelmaking, yuav tsum tau sib npaug ntawm:

Rauv Kev(muaj peev xwm, hluav taws xob hloov fais fab)

Cov Txheej Txheem Xav Tau(qib hlau qib, cov pa oxygen lice teeb)

Tus Nqi Muaj Zog(Txhua +100 hli nce electrode nqe los ntawm 15% tab sis txo tus nqi / tuj ntawm 4%) {3}
