Abstract

j Fremgangsmåte for å regulere og utbalansere en elek-!trisk ovns effekt i en smelte- eller oppvarmingsovn, 'hvor effekten mates til ovnen gjennom minst en elek-. •trode og hvor elektrodens spiss eller elektrodenes spisser under hele prosessfasen holdes på samme nivå. Effekten reguleres ved å endre spenningen mellom ovnens elektroder mens ovnens elektrotekniske størrelser i får variere fritt under prosessfasen. Ubalansen som kommer av elektrodenes konstruksjon og endringer i for-;holdene i ovnen, utbalanseres ved å regulere elektro-denes matning, slik at denne tilsvarer elektrodenes ; slitasje, under tilgodeseelse av de i ovnen målte i .størrelser og de med disses hjelp dannede kortvarige ' • og langvarige tendeser samt tendensenes linære avheng-: 'i igheter. j
