1. Menetelmä jatkuvan elektrodin valmistamiseksi, joka poltetaan sen ollessa suorassa yhteydessä uuniin, jossa sitä käytetään, ja jota siirretään alaspäin sitä mukaa kuin elektrodi kuluu uunissa, jolloin elektrodi vyöhykkeessä (B), joka on virran syötön aikaansaavan elektrodipitimen (22) yläpuolella, kuumennetaan 400-600°C:seen niin, että elektrodi on valmiiksi poltettu (vyöhyke C) ennenkuin se saapuu pitimeen (22), jossa virran syöttö elektrodiin tapahtuu, tunnettu siitä, että lämpö johdetaan vyöhykkeeseen (B) erillisen rengasmaisen elimen (18) kautta, joka on sovitettu elektrodin kehän ympärille, jolloin rengasmainen elin voi mahdollisesti kannattaa osaa elektrodin painosta.
2. Patenttivaatimuksen 1 mukainen menetelmä, tunnettu siitä, että rengasmainen elin toimii elektrodia ympäröivänä pysyvänä vaippana.
3. Patenttivaatimuksen 1 tai 2 mukainen menetelmä, tunnettu siitä, että vyöhykkeeseen (B) johdettava lämpö kehitetään vastuskuumennuksella, induktiolla, liekkikuumennuk-sella, lämmönvaihdolla tai konvektiolla. 7 81196
