Sažetak

This article analyzes the effect of zinc in the blast furnace process and it also analysis its contents in the input and output raw materials. The results obtained in the long-term research project will be used as data here. The removal of zinc from the input raw materials is very difficult already in the sinter production stage. This is due to its uniform distribution in the raw materials, but also due to the fact that it does not transfer into gas phase during the sintering process. The content of Zinc compounds was experimentally measured in the lining. The quantity of penetrated Zinc is different in different parts of the blast furnace. As demonstrated by the research, zinc repeatedly enters the blast furnace process, which leads to its circulation.
