Selecting the batch composition in arc furnaces for energy-saving operation

Monitoring of the energy consumption in an arc smelting furnace when using various materials permits the optimization of the batch composition. To this end, the corresponding multicriterial optimization problem is analyzed, and a method is proposed for determining the energy-saving batch composition. This method consists of six main steps, including the following: collection and organization of the technological information; plotting of cause-and-effect diagrams; and description of the electrical consumption by means of a multicriterial optimization problem containing a system of constraints with empirical coefficients.
