Energy considerations in planning slab furnaces at a steel company: A case study at SSAB
2014 (English)Manuscript (preprint) (Other academic)
To save energy and reduce costs we suggest production planning to consider issues with clear and large impact on both usage and costs of energy. This paper investigates how the energy system interacts with the production processes early in the value chain at a steel company. A case study at one of the company’s production facilities reveals promising opportunities to achieve increased energy efficiency by considering an energy‐related approach in planning of the continuous slab furnaces and the hot rolling processes. Analysis shows that energy can be saved and costs reduced through an alternative planning approach without taking any noteworthy investment cost. Improved communication within the different parts of the organization plays also a significant part in actualizing the managerial opportunities located. Real company data provided from the case company SSAB is used and analyzed. This paper contributes with a model used for analytical calculations on how market conditions could motivate a company to select different planning approaches. This by choosing a primary and secondary slab furnace based on their energy characteristics. As such, when the opportunities are beneficial enough, the impact of energy issues on production and supply chain planning should not be neglected.
