Abstract

Steels dusts from electrostatic processes, which are currently a problem in the ecological sense, is a rich but problematic carrier of many elements such as Fe, Zn, Mn, Cr. The existing recycling technologies, unfortunately, do not allow for their full recovery. The authors of the work decided to investigate the possibility of reducing the amount of waste to be deposited to the necessary minimum in the process of steel dust recycling.The paper presents the possibilities of using a metallic alloy, which was one of the products obtained as a result of the processing of steel dust in a resistance-arc furnace. The main objective of the dust processing research was the management and selective recovery. The products of the process were zinc oxide, slag and iron alloy. Iron recovery from dust was determined at the level of 98 %. The resulting iron alloy contained alloying elements such as manganese, chromium, and silicon in amounts enabling it to be used in the steel production process. The material can be used for the production of, for example, cast steel resistant to erosive and tribological wear.
