HP Graphite elektrodes foar Steel Making
De yntroduksje fan HP Graphite Electrode
Grafytelektrode mei hege krêft wurdt produsearre troch petroleumkoks mei leech-swevelynhâld (as naaldkoks) as grûnstoffen en stienkoalsfalt as bynmiddel troch kalsinearjen, ferpletterjen, batchjen, kneading, foarmjen, bakken, ympregnaasje, opnij bakken, grafitisearjen en ferwurkjen.Syn fysike en meganyske eigenskippen binne heger as gewoane macht grafyt elektrodes, lykas lege resistivity en grutte hjoeddeiske tichtheid.
De tapassing fan HP Graphite Electrode
(1) Foar stielen smelten yn elektryske arc furnace / ladle furnace
(2) HP Graphite elektrodes wurdt benammen brûkt yn elektryske bôgeofen foar stiel meitsjen.As grafytelektrode wurket yn EAF, sil de stroom troch grafytelektrode yn 'e oven ynfierd wurde, en d'r sil waarmteboarne wêze dy't wurdt generearre troch elektryske bôge tusken elektrodes ein en ovenlading foar smelten.
(3) Foar korund smelten yn elektryske oven
(4) Wurdt brûkt foar it ferwurkjen fan spesjale-foarmige grafytprodukten
De blank fan grafytelektrode wurdt ek brûkt om ferskate spesjale-foarmige grafytprod en grafytkroes, ensfh.
