1. A method for determining electrode consumption for each heat in an electric arc furnace, comprising the steps of:
providing a baseline electrode diameter;
measuring a red tip length of an electrode column in an electrode assembly using a machine vision system;
measuring a tip diameter of the electrode column using the machine vision system; and
determining in a computer processor a modelled consumption amount of the electrode column using the measured red tip length, the measured tip diameter and the baseline electrode diameter.
