Claims (3)

1. Fremgangsmåte ved drift av elektriske smelteovner for smelting av f. eks. oksydslagger eller sulfidslagger, som helt eller delvis arbeider med lysbuer, karakterisert ved at den elektriske spenning mellom elektrodeholder og ovnsbunn måles og at avvik i kurveform mellom den målte spenning og nettspenningen brukes som driftsmåling for styring av smeltebadets temperatur og tilførselen av usmeltet slagg.1. Procedure for operating electric melting furnaces for melting e.g. oxide slag or sulphide slag, which works wholly or partly with electric arcs, characterized by the fact that the electrical voltage between the electrode holder and the furnace bottom is measured and that deviations in curve form between the measured voltage and the mains voltage are used as operating measurements for controlling the temperature of the melting bath and the supply of unmelted slag. 2. Fremgangsmåte i henhold til krav 1, karakterisert ved at den målte elektriske spenning blir filtrert.2. Method according to claim 1, characterized in that the measured electrical voltage is filtered. 3. Fremgangsmåte i henhold til krav 1 og 2, karakterisert ved at den filtrerte elektriske spenning blir likerettet.3. Method according to claims 1 and 2, characterized in that the filtered electrical voltage is rectified.
