Usoro maka igbochi oxidation nke electrodes graphite n'oge nchara.A na-eji electrodes graphite na arc metallurgy dị ka ihe na-eri nri, ọnụ ahịa oriri ha na-akwụkwa ihe dịka 10-15% nke ọnụ ahịa igwe ọkụ eletrik.

N'ime afọ ndị na-adịbeghị anya, iji mee ka nrụpụta ọkụ eletrik dịkwuo mma ma belata oriri ọkụ, ọkụ eletrik anabatala ọrụ dị elu, na oriri oxidation nke electrode na-ebuli na-abawanye, si otú ahụ na-abawanye ụbara oriri electrode na ịgbaze ego. ị oxidize graphite electrode

Enwere ike ichebe electrodes graphite megide oxidation site n'itinye mkpuchi nchebe n'elu electrode.Nke a bụ ụzọ ụfọdụ maka igbochi oxidation nke electrodes graphite:

1. Mbụ, a gburugburu nke na-emighị emi grooves na- machined n'elu nke graphite electrode, nzube bụ ime ka cermet oyi akwa nwere ike guzosie ike n'elu nke graphite electrode, na mgbe ahụ, graphite electrode na-ewe iwe dị ka 250 ℃ na. ọkụ ọkụ na-ekpo ọkụ, mgbe ahụ, a na-eji egbe ịgba ígwè na electrode.N'elu elu, fesaa akwa aluminom dị mkpa, fesaa oyi akwa cermet slurry ọzọ na oyi akwa aluminom, wee jiri carbon arc na-agbanye slurry, fesa slurry na arc sinter, megharịa ugboro 2-3 iji mee cermet The oyi akwa nwere. oke ọkpụrụkpụ.

Nguzogide cermet bụ 0.07-0.1pm, nke dị ala karịa nke electrode graphite.Na 900 ℃ maka 50h, gas bụ impermeable na mkpuchi decompositioned okpomọkụ bụ 1750-1800 ℃.Ihe mejupụtara ihe mkpuchi ahụ enweghị mmetụta na nchara a wụrụ awụ.Ịbawanye akụrụngwa, ọkụ eletrik na ọrụ a na-eji na mkpuchi mgbochi oxidation ga-abawanye ọnụ ahịa nke electrodes graphite site na 10%, mana ọnụọgụ nke electrodes graphite kwa ton nke igwe ọkụ eletrik nwere ike belata site na 20-30% (n'ihi ya. eji na ọkụ eletrik nkịtị).Ebe ọ bụ na mkpuchi bụ ihe na-agbaji agbaji, cermet bụ ihe na-agbaji agbaji, ya mere zere nkukota mgbe ị na-eji ya, ma emela ka mkpuchi ahụ kwụsị.

2. Mbelata ikpughe na ikuku: Ekwesịrị ịchekwa electrodes graphite na ebe akọrọ na ikuku na-enweghị ikuku iji gbochie ikpughe na mmiri na ikuku.Nke a ga-enyere aka igbochi oxidation.

3. Iweda okpomọkụ na-arụ ọrụ: Ịrụ ọrụ electrode na obere okpomọkụ nwere ike ibelata ohere nke oxidation.Enwere ike ime nke a site na ibelata ihe dị ugbu a ma ọ bụ ịbawanye oghere electrode.

4. Iji gas nchebe: Enwere ike iji gas na-echebe dị ka argon ma ọ bụ nitrogen n'oge ọrụ iji gbochie oxidation.Gas na-enyere aka ịmepụta ikuku nchebe gburugburu electrode.

5. Nhicha nke ọma: ihicha nke ọma nke electrode tupu arụ ọrụ nwere ike wepụ ihe ọ bụla adịghị ọcha ma ọ bụ ihe ndị na-emerụ emerụ nke nwere ike ime ka oxidation.

Oke ngwa: Kwesịrị ekwesị maka ngwaahịa graphite dị ka graphite electrodes, anode carbon blocks, electrolytic aluminum osisi, graphite ebu, graphite crucibles, na ndị ọzọ graphite ngwaahịa n'elu sealing mgbochi oxidation, akara mgbochi corrosion, ịgbatị ndụ nke graphite ngwaahịa site na opekempe 30%, na-abawanye ike ihe.
