Abstract

This work is focused on the usage of metallurgical waste as an input material to the blast furnance. Firstly there is defined the basic metallurgical waste formed during metalurgical process. Then the other ones, which are well-used as an input material to the blast furnance, such as blast-furnance slag and steel sheet slag, scale, various kinds of dust and sludge. The major parts of the industrial waste is in form of very fine-sized elements of sludge. The waste can be used after the elimination of impurities from the wastes and their solidification making parts. There has been changed some atributes in waste such as the amount and the structure of waste during increasing and modernising the technologies. The comparisons of using wastes in ČR and in abroad has been made too.
