Publisher - Primetals Technologies

Category - Engineering & IT

The paper discusses recent innovations of Primetals Technologies in the field of micro- and minimills, furnace technology, casting and rolling technology, which all address the “high efficient minimill” approach enabling a future-oriented, sustainable steelmaking while saving resources and creating clear added value. Significant energy savings can be achieved by utilizing state-of-the-art technologies. Efficient scrap preheating in Quantum EAF results in 20% lower conversion cost for the melting process. Compact minimill design of the endless type reduces the mill conversion cost by a further 10% and improves yield by 1.5-2 percentage points. Use of advanced automation technologies (smart sensors, robots, integrated process control and –optimisation solutions) improves plant operation and utilization.
