For the BFBOF route as shown in the lefthand side of Fig. 1, the material inputs are predominantly iron ores and the energy inputs are coal and electricity [15]. The steel is produced with several processing steps, including coking, sintering, pelletizing, ironmaking, primary and secondary steelmaking, casting, and hot rolling [16].

The rolling process begins by continuous casting 7, or if an older, not modernized steel plant is considered, by ingot the most modern mills continuous casting is followed directly by hot rolling. In all of these cases the prerolling structure consists of dendrites which are subsequently removed in the reheat furnaces in which most of the alloying elements enter into solid solution.

Additionally, the possible development until 2050 is analysed. The results show the high impact of continuous reheating furnaces in steel hot rolling mills on the total CO 2emissions of downstream steel processing. Furthermore, the massive increase in electrical energy consumption of the whole steel production process is highlighted.
