KTH Royal Institute of Technology

KTH Royal Institute of Technology in Stockholm has grown to become one of Europe’s leading technical and engineering universities, as well as a key centre of intellectual talent and innovation. We are Sweden’s largest technical research and learning institution and home to students, researchers and faculty from around the world. Our research and education covers a wide area including natural sciences and all branches of engineering, as well as architecture, industrial management, urban planning, history and philosophy.

Project description

Third-cycle subject: Engineering materials science

The production and quality development of Swedish low- and high alloyed niched steels is problematic due to the fact that the stirring intensity cannot be measure during production. The project aim is to solve this by using a combination of indirect measurements with new mathematical methods for signal analysis and machine learning including necessary databases. An initial pre-study has been made based on conditions in Sweden, which shows that a potential exist using vibration measurements to obtain indirect measurements of the stirring intensity as well as reaction progress. During step 1, a deep literature study will be carried out. These results in combination with the results from discussions during a workshop will be used to determine the most suitable methodology for the initial plant trials. In step 2a, initial plant trials will be made to measure the stirring intensity when using gas and/or induction stirring of steel in ladles. At the same time, the reaction process of decarburisation in the AOD converter will be investigated for vibration in step 2b. Based on these measurements and a deep analysis of data using modern signal processing and machine learning methods, long plant campaigns will be performed in step 3a and 3b to determine the capability of the methodology to provide process feedback which can be used for an improved process control. The implementation of this methodology will lead to faster kinetic processes for different metallurgical operations, which will support a sustainable production.

You will be required to work in close collaboration with other researchers from SWERIM and industry.  The project will require a significant amount of experimental work.  Critical assessment of scientific literature and the data collected during the project will be vital.  Creative and analytical problem solving skills are also required.

The position is for two years and leads to a Licentiate degree.
