Te whakamahi me te mahi o te hiko kauwhata

Tuatahi, te whakarōpūtanga o te hiko kauwhata

Kua wehea te hiko graphite ki: te hiko kauwhata hiko noa (RP); High power graphite electrode (HP); Uira-tiketike 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 wera, ko te ia na roto i te parenga utu ka whakaputa wera ano.

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 rauemi 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 graphite electrode, graphite pokepokea ai me graphite crucible 3 momo o tiketike pāmahana rauemi hiato, e toru rauemi graphite i tiketike pāmahana, graphite he ngāwari ki te oxidize tauhohenga ngingiha, na i roto i te mata o te paparanga waro o te rauemi. , whakapai ake i te hanganga kauwhata kauwhata wewete.
