Txais tos hu rau peb rau kev hais.
Conductivity yog lub thoob ntiaj teb cov electrodes, txiav txim siab lawv lub peev xwm los hloov lub zog hluav taws xob muaj zog hauv siab. Rau 550mm Graphite Electrodes -} {{{4 4} {{4 4} {} Cov nqi hluav taws xob, thiab kev ua haujlwm zoo, thiab ua haujlwm ntev.
Graphite lub inherent conductivity stems los ntawm nws cov qauv txheej carbon monuple, qhov twg durocalized hluav taws xob ua kom cov hluav taws xob nrawm. Txawm li cas los xij, tsis yog txhua graphite hluav taws xob raug tsim kom sib npaug. Qhov kev tshaj tawm ntawm 550MM electrode yog puab los ntawm peb qhov tseem ceeb ntawm qhov tseem ceeb:Cov Khoom Siv Purity, Graphitization degree, ThiabPority Tswj.
Ua ntej tshaj, raw khoom siv purity yog tsis - kev sib ceg. High {- kev ua tiav 550 hli cov khoom siv tau tsim los ntawm ultra {{} {5} {} {} {} sulfur roj cke (cov lus faj sulfur cov ntsiab lus<0.3%) and high-grade coal tar pitch. Impurities like sulfur or iron increase electrical resistance by disrupting the carbon lattice, forcing electrons to scatter. By limiting impurities to <0.1%, manufacturers ensure minimal resistivity (as low as 50–55 μΩ·m for premium grades).
Thib ob, graphitization kub thiab ntev yog pivotal. Thaum lub sij hawm graphitization (2,500-3,000℃hauv inert atmospheres), carbon atoms rearnange mus rau crystalline qauv, ua raws li txoj hauv kev hauv hluav taws xob. Rau 550Mm Electrodes, Txuas Ntxiv Graphitization (txog 48 teev) txo qhov kev tiv thaiv los ntawm 30-40% piv rau cov qauv hluav taws xob, txhim kho kev ua haujlwm.
Thib peb, Kev tswj Porosity tswj hwm kom tau txais kev coj ncaj ncees. Peem ntxeem graps huab cua lossis electrolytes, tsim cov thaiv hluav taws xob insulating. Advanced processes like resin or pitch impregnation seal micro-pores, reducing contact resistance. Piv txwv li, ib 550mm electrode nrog 5% porosity (vs . 15% nyob rau hauv unimpregnated variants) tuaj yeem qis zog poob los ntawm 15-20% hauv EAF.
Hauv cov ntsiab lus siv tswv yim, ib 550 hli siab -}} tuj}} Kuv muaj voltage qis dua li cov neeg voltage qis dua li qis-qib counterparts. Qhov no txhais lus rau 10-15% txuag hluav taws xob ib tev ntawm cov hlau, ib qho tseem ceeb kom zoo rau kev lag luam uas cov nqi tsim hluav taws xob.
Hauv cov ntsiab lus, 550mm graphite electrode kev xaiv yog encision cov khoom siv, thiab porosity tswj art} {{2} {{2} Cov haujlwm ua tau zoo.
