HP GRAPHITE ELECTRODES - Dhexroorka u dhexeeya 200 mm ilaa 600 mm
HP GRAPHITE ELECTRODES - Dhexroorka u dhexeeya 200 mm ilaa 600 mm
SHARAXAAD
Elektroodka HP graphite waa curiyaha hagaya foornooyinka korantada ee sameynta birta. Waxaa laga sameeyay kookaha batroolka, kookaha irbadda, dhuxusha waxaana soo saara taxane habab wax soo saar oo adag. Khadadka hadda jira ee sarreeya ayaa dhex mara dekedda elektroodka garaafka ee gudaha jirka foornada. Tani waxay sii deyn doontaa tamar koronto foornada qaansada si ay u kululeyso foornada.
Baahida loo qabo elektroodhada dhexroorka weyn ayaa sii kordheysay iyadoo cabbirka foornada EAF uu sii weynaaday. Elektroodhada garaafka leh ee dhexroorkoodu yahay 500 mm ama 600 mm ayaa si isa soo taraysa caan u noqday sannadihii ugu dambeeyay.
ASTAAMAHA
Daawaynta ka hortagga oksaydhka si loo helo cimri dheer.
Daxal sare, cufnaan sare, iyo xasillooni kiimiko oo xooggan.
Saxnaanta mashiinka sare, dhammaystirka dusha sare oo wanaagsan.
Awood farsamo oo sareysa, iska caabin koronto oo hooseysa.
U adkaysi u leh dildilaaca iyo xoqidda.
Iska caabin sare oo ku wajahan oksaydhka iyo shoogga kulaylka.
CODSIGA
Elektroodhada graphite waxaa si weyn loogu isticmaalaa soo saarista biraha daawaha, birta iyo walxaha kale ee aan birta ahayn, iwm.
Foorno koronto oo DC ah.
Foornada korantada ee AC-ga.
Foorno qaanso ah oo hoos u dhacday.
