EAF Graphite hluav taws xob Ultra siab zog

Nyob rau hauv uas EAF scenarios yog Ultra muaj lub zog siab (UHP) graphite electrodes feem ntau qhov tseem ceeb, thiab vim li cas?

​

UHP Graphite hluav taws xob yog hom phiaj - ua rauLoj, siab - fais fab EAF(Feem ntau ntau dua lossis sib npaug rau 100 tons muaj peev xwm, loj dua los yog sib npaug rau 80 mw lub zog tsim nyog), qhov twg maximizing khoom siv thiab txo cov hluav taws xob pov tseg yog qhov tseem ceeb. Cov ntawv thov tseem ceeb muaj xws li:

​Loj - teev steel ntau lawm:UHP Electrodes Excel nyob rau EAFs tsim 150-300 tons ntawm cov hlau rau ib qho kub. Lawv cov kev tsis tshua muaj kev txo qis hluav taws xob poob los ntawm 20-30% piv rau HP electrodes, cov nqi sib zog (ib qho kev siv hluav taws xob loj hauv steelmaking).

​Hwm Steel Raug:Kev kho tsheb, aerospace, lossis cuab yeej hlau qib xav tau cov ntsuas kub kub (± 10℃kom tswj tau cov huab cua ruaj khov, ua kom cov teeb tsa nruab nrab micruction thiab zoo ib yam.

​Nruam Cov Chaw Ua Haujlwm:​ Modern EAFs often run 24/7 with minimal downtime. UHP electrodes' superior mechanical strength (>10 MPA) txo cov burnage los ntawm 30-40% tiv thaiv HP, txo qis kev kaw thiab txhim kho txhua xyoo tso zis los ntawm 10-15%.

Hauv kev sib piv, EAF me me (<50 tons) or legacy mills with limited power (<50 MW) rarely use UHP electrodes due to higher upfront costs; RP/HP grades suffice for their lower current demands.
