HP Graphite Electrode
Habka wax soo saarka ee electrodes graphite guud ahaan waxaa ka mid ah: alaabta ceeriin (dhogorta) → baking → cajiin → extrusion molding → sintering heerkul sare (1550 ~ 1700 ° C) + daaweynta kulaylka (1100 ~ 1200 ° C) + dhammayn.
1. dhogorta hore u sii daawayn: ka saar wasakhda ku jirta dhogorta.Habka ugu muhiimsan ee wasakhdu waa in la isticmaalo biyaha lagu dhaqo ama alkali dhaqida.
2. Waxyaabaha ay ka kooban tahay: Ku dar qaddar cayiman oo ciid quartz ah markaad cajiinayso, oo ku rid alaabta ceeriin ee isku dhafan qalabka wax lagu cajiiyo.
3. Kneading: Ku rid alaabta ceeriin ee isku qasan bartamaha graphite extruder, ka dibna cajiin oo soo saar alaabta ceeriin ee cajiin si aad ugu sameysid caaryada garaafka.
4. Duubista: Ku gub walxaha isku qasan ee dhuxusha ku jira kulayl guduudan ama walxaha guban sida kaarboon madow iyo budada dhuxusha, ka dibna geli habka xiga.
5. Dhammayn: Ka dib marka caaryada la sameeyo, waxay u baahan tahay in la gooyo, la dhufto, la nadiifiyo iyo habab kale.
6. Baakadaha: Caaryada waa in la eego (oo ay ku jiraan nadaafadda iyo haddii ay jiraan waxyeello iyo xagtitaan iwm) oo la kala soocaa oo la isku dhejiyo ka hor inta aan lagu kaydin bakhaarka.
Shaqooyinka lakabka dallaca carbonization waa: si loo ilaaliyo kharashka oksaydhka heerkulka sare, si loo hubiyo in walxaha birta ah ee ku jira slag aysan isbeddelin;si loo ilaaliyo falcelinta dhimista karbothermal ee gobolka dhalaalaysa, si loo hubiyo in kharashka lagu dhalaalayo heerkulka ugu fiican iyo wakhtiga.
Shaqada ugu weyn ee foornada arc koronto waa in la soo bandhigo arc koronto ah oo lagu soo dallaco si loo dhalaaliyo walxaha birta kaarboon ee dhalaaliyay ee birta ah.Qalabka korantada ee foornada arc koronto guud ahaan waa electrode graphite, anode iyo graphite cathode.
Foornada Carbonization: Dhuxusha waxaa lagu gubaa foornada si ay u soo saarto kaarboon iyo ogsijiin, gaaska qiiqa ka dhashana waxa uu galaa barkada dhalaalaysa ka dib marka la qaboojiyo, birta dhalaalaysana dibadda ayaa laga soo daayaa isku mar.
Kiln Rotary: Fool yar ayaa loo isticmaalaa habka dhalaalidda biraha ama alwaaxyada.
