400 UHP graphite electrode
Ma electrode a graphite amagwiritsidwa ntchito kwambiri popanga zitsulo. Chitsulo chachitsulo chimasungunuka mu ng'anjo yamagetsi yamagetsi ndikusinthidwanso. Monga ngati kondakitala, iwo ndi chigawo chofunikira mu mtundu uwu wa
UHP graphite elekitirodi imapangidwa makamaka ndi singano ya singano yapamwamba kwambiri, ndipo imagwiritsidwa ntchito kwambiri m'malo opangira magetsi amphamvu kwambiri.

Njira yopanga
Ma electrode a graphite amapangidwa makamaka ndi petroleum coke ndi singano coke, wothira malasha phula, kudutsa njira za calcinations, kneading, kupanga, kuphika, graphitizing ndi Machining, potsiriza kukhala mankhwala. Nawa mafotokozedwe azinthu zina zopanga:
Kukanda: Kusakaniza ndi kusakaniza tinthu ta carbon ndi ufa ndi kuchuluka kwa binder pa kutentha kwina, njirayi imatchedwa kukanda.
Ntchito yokanda
①Sakanizani mitundu yonse ya zopangira mofanana, ndipo nthawi yomweyo pangani zida zolimba za kaboni zamitundu yosiyanasiyana ya tinthu ting'onoting'ono, sakanizani ndikudzaza, ndikuwongolera kachulukidwe kawo;
②Mukawonjezera malasha, phatikizani zinthu zonse pamodzi.
③Miyendo ina ya malasha imalowa mkati mwa zotupa zamkati, zomwe zimapangitsa kuti kachulukidwe ndi kumamatira kwa phala.
Kupanga: The kneaded carbon phala ndi extruded mu thupi wobiriwira (kapena wobiriwira mankhwala) ndi ena mawonekedwe, kukula, kachulukidwe ndi mphamvu mu akamaumba zida. Phala lili ndi mapindikidwe apulasitiki pansi pa mphamvu yakunja.
Kuwotcha kumatchedwanso kuphika, Ndiko kutentha kwambiri, kumapangitsa kuti malasha apangidwe kuti apange coke, omwe amaphatikiza ma carbonaceous aggregates ndi tinthu tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono, kutsika kwa resistivity, kukhazikika kwabwino kwa kutentha ndi kukhazikika kwa mankhwala.
Kuwotcha kachiwiri ndikuphikanso kamodzinso, kupangitsa kuti phula lolowera likhale la carbon. Ma elekitirodi (mitundu yonse kupatula RP) ndi nsonga zamabele zomwe zimafunikira kusachulukira kwakukulu zimafunika kuphikidwa kachiwiri, ndi nsonga zamabele atatu kuviika anayi kuphika kapena kuwirikiza katatu kuphika.
