Abstract
The article discuses the main reasons causing heat losses by radiation and the opportunities to decrease them in a three phase arc steel melting furnace. According to the results of the study, the relation between the arc efficiency and the slag layer depth is presented. The investigation revealed the relation between the arc efficiency and electric regime and the ratio of arc penetration into the metal and slag to the arc length.
Keywords
