Summary:Reduction of CO2 emissions in the steel sector is essential and many producers have announced their pathway towards net-zero carbon. DR using low-carbon hydrogen seems to be a promising alternative achieving much lower emissions than today's BFs. But on the raw material side, the importance of iron ore needs to be considered, and data show that the majority of the ores today are of lower grade and hence, a two-step process is required. This process combines a smelter for melting and reduction with a BOF converter for the refining work and is, therefore, predestined for implementation into existing integrated plants. Primetals Technologies' smelter is designed to handle a wide range of input materials such as pellets, fines, briquetted DRI as well as byproducts.
