emphasis is on the development of analysis methods and tools for an integrated steel mill. Several applied studies of the integrated steel mill of SSAB Tunnplåt AB have been carried out. The results show that large savings in energy, cost, and emissions to the environment can be achieved using the analysis methods developed.

The general layout of a steel plant is the physical arrangement of its production and supporting facilities such as production shops, equipment, machineries, buildings, and road, rail and pipe network etc. The layout determines the way in which materials and other inputs (such as information etc.) flow through the operation.

An integrated steel mill typically meets both criteria. A previous study by the authors (Sundqvist et al., 2018) examined how the excess energy from the steel mill in Luleå, Sweden, that is currently used for district heating, process heat, and electricity production could be extended to drive also partial capture. The heat sources, which ...

Introduction. Humankinds now is facing severe thread of exhaustion of fossil fuel and the global warming by greenhouse gas (GHG). The iron and steel manufacturing production has an enormous energy consumption and CO 2 emissions [1]. The large production of crude steel, especially under the long route process, led to a high-energy …

While by the end of the century most steel mills will feature a Carbon Direct Avoidance process, forecasts indicate that in 2050 more than 50% of steel will still be produced by the integrated BF-BOF process due to long mill lifetimes and investment cycles in the industry (Arens et al., 2017; EUROFER, 2019).
