Special waste processing profi tabilities in the blast furnace

Abstract

For centuries, pig iron has been produced from iron ore using slag formers and coke to produce liquid pig iron. Thermal simulation methods of pig iron production and metallurgy in general make it possible to predict the success of the disposal or recovery of many wastes. So far, the metallurgy has made use of its recycling potential in a narrow way, generally based on an examination of its internal operating conditions, and has largely refrained from using waste from other industries in the economy, with the exception of steel scrap and steel scale.
The publication has taken advantage of this opportunity. The paper presents examples of the techno-economic analysis of four non-ferrous, so-called special wastes, thereby extending the scope of the potential of waste, including hazardous waste, from the external sector to the production of pig iron.
