Important results from the project
Referring to the original problem statement, the project has successfully addressed the challenge of producing high-quality ferritic ductile iron by using mill scale to control the manganese content of molten iron. This method enables foundries to increase the use of local scrap material, reducing reliance on costly imported pig iron and improving the sustainability of the production process. The results show that mill scale material can be effectively used to oxidize manganese.
Expected long term effects
The results from this project have started to be implemented in Norrlandsgjuteri´s activities and are expected to influence other foundry companies. This strategic change improves the quality of the ductile iron produced and reduces dependence on expensive imported pig iron. The benefits of these results include ´no change in product quality´, lower production costs and a reduced carbon footprint linked to importing raw materials, particularly significant considering trasnport CO₂ emissions.
Approach and implementation
The project´s structure and activities were well planned and in line with the schedule. Some challenges arose during industrial testing, where we realized the need for better temperature control. At the laboratory level, this was not a problem. In addition, scrap material composition varied, making the use of scrap in laboratory tests challenging. The cooperation between the parties worked very well and was highly appreciated, which contributed to the success of the project.
