- Abstract
We discuss various issues involved in processing of ferrous metallurgical waste, specifi cally blast-furnace and converter waste, using the ArcelorMittal Temirtau experience as an example. We study the methods currently used for disposition of these materials by the company and by the ferrous metallurgy industry as a whole, as well as potential reprocessing methods proposed by researchers in the CIS and other foreign countries. The analysis performed here indicates that blast-furnace slag is appropriate for use as a material in sub-bases for roads. We propose a method for improving the physical and mechanical characteristics of blast-furnace slag, including filling the pores in the slag with a cement/microsilica mixture and making the slag water-repellent with used motor oil. We describe the results of experimental studies performed on the resulting material. Given that the company produces 600,000 metric tons of blast furnace slag per year, using this approach for complete reprocessing and subsequent sale of the slag will reduce the production costs for ArcelorMittal Temirtau end products by 1.725 million US dollars per year, provide an alternative raw material for users, reduce environmental impacts, and conserve natural resources.
