Abstract: Analysing the function of steel scrap and understanding its influence on development, are the main problems which interests the steel producers of the world. To create such an essay, the analysis of the actual developments of the quantities, the qualities and compositions of the used scrap types should be continuously monitored in the world’s steel industry. Series of local experiments and evaluating statistics focusing on process optimization by scrap have been done at ThyssenKrupp Steel. This includes the current study based on the records of scrap charges. In the following paper the development of an indirect scrap evaluation algorithm will be discussed, compared with results of the common ways.

Abstract: The metallurgical slag is a normal building material in Europe but not in Hungary. I prove by my own researches that the electric arc furnace slag isn’t harmful to the nature especially the ground water and their physical aspects are similar to the natural rocks. It means that we can use slag to replace them to save our environment and to clear away the old slag dumps.
