Abstract
In a method of producing metal melts, in particular a steel melt from scrap, in an electric arc furnace having at least one graphite electrode, organic substances are charged into the electric arc through a central longitudinal recess of the graphite electrode so as to reduce electrode consumption.
Claims5
In a method of producing metal melts in an electric arc furnace comprising at least one graphite electrode having a tip end at which an electric arc is formed, while substantially reducing electrode consumption in the region of the tip end, the improvement wherein said at least one graphite electrode has a central longitudinal opening therethrough and wherein thermally decomposable organic substances are charged into the electric arc formed in said electric arc furnace through said central longitudinal opening of said at least one graphite electrode such that thermal decomposition of said organic substances results in a cooling effect of said electrode, thereby substantially reducing electrode consumption.
