Forbedrede produkter for metallbehandling under støpejern produksjon

Offentlig prosjektsammendrag

During cast iron production, liquid metal treatment is of crucial importance for the final product quality. The treatments aim at controlling the nucleation and shape of graphite and drastically affect the microstructure and therefore the final mechanical properties. Graphite nucleates on nuclei that are precipitated in-situ from dissolved elements added with ferro-silicon as a carrier. In this project, different ferro-alloys qualities will be used for liquid metal treatment that will then be solidified under a variation of conditions (for example, thick sections and thin sections castings). The castings will be characterized especially with methods enabling the characterisation of microparticles in the matrix. Modelling methods will also be used to predict the formation of these microparticles helping to choose the combinations of elements and conditions to test.
