Purpose and goal
This feasibility study aims to clarify whether a pre-melted alloy consisting of manganese and aluminium with sufficient good quality can be produced from secondary materials containing metallic aluminium and manganese oxide. The aim of the project has been reached. The function of the pre-melted alloy from secondary sources has been verified through industrial tests with good results.
Expected results and effects
Results from trials shows that it is possible to produce a good pre-melted alloy based on secondary sources. The content of minor elements as iron and silicon depends on which source of manganese which is used. Industrial plant trials has verified the function of the alloy in terms of dissolution and product quality The estimated full effect of the project is a sustainable production of a new Mn-Al alloy covering the entire Swedish demand.
Planned approach and implementation
The project has been organised as a feasibility study with the first part conducted during 2017-2018. Seven work packages have been performed in this study. The general working flow has been to produce a smaller amount of a pre-melted alloy, study the kinetics of the dissolution and finally verify the function of the alloy in plant trials ranging from alloying to material investigation of the final product. It is planned to continue the development in future projects to realise increased competitiveness of the Swedish industry.
