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.
