Tuatahi, te whakarōpūtanga o te hiko kauwhata
Kua wehea te hiko graphite ki: te hiko kauwhata hiko noa (RP);High power graphite electrode (HP);Te hiko hiko kauwhata hiko (UHP).
Tuarua, ko te whakamahi i te graphite electrode
1. Ka whakamahia mo te hanga rino oumu arc hiko
Ko te nuinga o nga rauemi electrode graphite e whakamahia ana i roto i te hanga hiko oumu hiko.Ko te hanga hiko o te oumu hiko ko te whakamahi i te graphite electrode ki roto i te oumu ki te whakauru i te waa mahi, ko te kaha o te waa kei raro o te hiko ka taea ma enei taiao hau ki te whakaputa i te awe o te tuku arc, ma te whakamahi i te wera i hangaia e te arc ki te whakarewa. .Ko te rahi o te kaha o te hiko, he mea taputapu ki nga electrodes graphite me nga diameters rereke, ka taea te whakamahi tonu, ki te hononga i waenga i nga hononga hiko hiko.Ko te graphite e whakamahia ana i roto i te hanga maitai hei taonga hiko mo te 70-80% o te tapeke o te kauwhata i Haina.
2.Used mo te kohuke waiariki oumu hiko
Whakamahia mo te hanga o te ferroalloy oumu rino, silicon parakore, ūkuikui kōwhai, konupūmā carbide me Hāmā, e te āhuatanga e te wahi o raro o te electrode conductive tanumia i roto i te tiaki, na i roto i te tua ki te pereti hiko me te pewa hiko i waenganui i te utu. ki te whakaputa i te wera, ko te ia na roto i te parenga utu ka puta ano te wera.
3.Mo nga oumu parenga
I roto i te tukanga o te hanga, te oumu graphitization mo nga hua rauemi graphite, oumu mo te karaihe whakarewa me te oumu hiko mo te silicon carbide he oumu aukati.Ko te whakahaere o nga rawa i roto i te oumu ehara i te mea he whakamahana anake, engari ano hoki te mea hei whakamahana.
4.Hot mate makanga mate me te korehau oumu whakamahana me etahi atu hua motuhake
Me kï hoki i roto i te whakauru i te graphite electrode, graphite pokepokea ai me graphite crucible 3 momo o tiketike pāmahana rauemi hiato, e toru rauemi graphite i tiketike pāmahana, he ngāwari ki te oxidize graphite tauhohenga ngingiha, na i roto i te mata o te paparanga waro o te rauemi , whakapai ake i te hanganga kauwhata kauwhata wewete.
