The paper in its introduction describes main principles of technical and economic analysis the application of which leads to determination of potential costs savings and subsequently to costs reduction. The application of the method is illustrated by an example of production of three types of steel grades for cast steel produced in five tons electric arc furnace. With the aid of the calculation model, incomplete costs of selective complex of the melts were determined (30 melts within the first phase and 260 in the second one). Incomplete costs and selected physical indicators (e.g. melting time, electrical energy consumption etc.) were subsequently compiled with the aid of statistical analysis. After that, the individual selective complexes were compared with each other (according to melters; first and second melt on the shift; melting with one or more charge basket; days in a week). The detailed analysis of these outcomes resulted in many particular recommendations how to reduce the costs in the foundry. The final recommendation for the melting shop is a proposal to introduce continuous monitoring of costs.
