The paper presents the results of measurements which test steel purity achieved using the Single Spark Evaluation (SSE) method. It describes the possibilities of using this method for the ways in which it is possible to carry out the correction of the current technology of steel making in the production line of an electric arc furnace, ladle furnace and caisson (EOP-LF-VD) in the steel works of Vítkovice Heavy Machinery a.s. Increasing steel purity and all mechanical properties of steel can be achieved by means of technologies which use secondary metallurgy equipment. Controlling the production of melts in the secondary equipment affects mainly the quantity, size and morphology of inclusions.
