Habka looga hortagayo oksaydhka ee electrodes graphite inta lagu jiro samaynta birta.Electrodes-ka graphite waxa loo isticmaalaa birta birta ee arc sida walxo la isticmaali karo, kharashkooda isticmaalkuna waxa uu ka dhigan yahay 10-15% qiimaha birta foornada korontada

Sanadihii la soo dhaafay, si loo hagaajiyo wax soo saarka foornooyinka korontada iyo in la yareeyo isticmaalka tamarta, foornooyinka korontada ayaa qaatay hawlgallo culus, iyo isticmaalka oksaydhka ee dusha sare ee korantada waxay u egtahay inay korodho, taas oo sii kordhinaysa isticmaalka korantada iyo kharashka dhalaalinta. Haddaba sidee samaynaysaa waxaad oksijiye electrode graphite

Electrodes-ka graphite waxa laga ilaalin karaa oksaydhaynta iyadoo la marinayo dahaar ilaalin ah oogada korantada.Waa kuwan qaar ka mid ah hababka looga hortagayo oksaydhka ee electrodes graphite:

1. Marka hore, goobada jeexjeexyada gacmeedka ayaa lagu farsameeyaa dusha sare ee graphite electrode, ujeedadu waa in la sameeyo lakabka cermet si adag u hoggaansanaanta dusha sare ee electrode graphite, ka dibna graphite electrode waxaa lagu kululeeyaa ilaa 250 ℃ in foornada kululaynta, ka dibna qori buufin bir ah ayaa loo isticmaalaa korantada.Dusha sare, ku buufi lakab khafiif ah oo aluminium ah, ku buufi lakab kale oo cermet slurry ah lakabka aluminiumka, ka dibna isticmaal arc kaarboon si aad u daadiso dareeraha, buufin slurry iyo arc sinter, ku celi 2-3 jeer si aad u samayso cermet lakabka ayaa leh dhumuc ku filan.

Iska caabbinta cermetku waa 0.07-0.1pm, taas oo ka hooseysa kan korantada graphite.At 900 ℃, waayo, 50h, gaaska waa impermeable iyo heerkulka dumis daahan waa 1750-1800 ℃.Halabuurka curiyaha daahan wax saameyn ah kuma laha birta dhalaalaysa.Kordhinta alaabta ceeriin, korantada iyo shaqada loo isticmaalo daahan ka-hortagga oksaydhisku waxay kordhin doontaa kharashka graphite electrodes by 10%, laakiin isticmaalka unugga ee electrodes graphite per tan ee foornada korontada lagu yareeyo 20-30% (natiijada isticmaalka foornooyinka korontada ee caadiga ah).Maadaama dahaarka uu yahay shay jajaban, cermetku waa walxo jajaban, markaa iska ilaali shil markaad isticmaalayso, hana ka dhigin dahaarka inuu jabo.

2. Yaraynta soo-gaadhista hawada: Electrodes-ka graphite waa in lagu kaydiyaa meel qalalan oo aan hawo lahayn si looga hortago soo-gaadhista qoyaanka iyo hawada.Tani waxay kaa caawin doontaa ka hortagga oksaydhka.

3. Hoos u dhigista heerkulka shaqada: Ku shaqaynta elektirodka heerkulka hoose waxay yareyn kartaa fursadaha oksaydhka.Tan waxaa lagu gaari karaa iyadoo la dhimo hadda ama la kordhiyo kala dheereynta korantada.

4. Isticmaalka gaaska difaaca: Gaaska difaaca sida argon ama nitrogen ayaa la isticmaali karaa inta lagu jiro hawlgalka si looga hortago oksaydhka.Gaasku waxa uu caawiyaa in uu abuuro jawi ilaalin ah oo ku wareegsan korantada.

5. Nadiifinta saxda ah: Nadiifinta saxda ah ee electrode ka hor qaliinka waxay ka saari kartaa wixii wasakh ah ama wasakh ah oo keeni kara oksaydh.

Baaxadda codsiga: Ku habboon alaabta graphite sida electrodes graphite, blocks carbon anode, electrolytic aluminium dhirta, graphite caaryada, graphite crucibles, iyo alaabta kale ee graphite dusha shaabadeynta anti-oxidation, xidhidhiyaha anti-daxalka, dheeraynta nolosha alaabta graphite by at at ugu yaraan 30%, kordhinta xoogga alaabta.
