Optimization of integrated steel plant recycling: Fine-grain remains and by-products synergy

Abstract

The recycling capabilities of the integrated steel plant (capacity 2 million tons/year), have been evaluated annually. The quantities of dusts, scales and sludge generated at the Steel Plant located in Smederevo, Serbia, have been determined, along with qualitative aspects and basic economic analysis. This paper presents suggestions for new waste management procedures, utilisation of the recycled resources and promotion of effective by-product synergy. A schematic preview of material flow of wastes and by-products formation, recycling, valorisation or disposal in agglomeration, blast furnace process, converter plant and hot and cold roll mills is presented. The loss of ferrous materials in non-recycled waste, including its economic value as a secondary raw material, is also presented.
