   Abstract : Nowadays, it has become crucial to transform company production processes in order to reduce carbon emissions. Therefore, the company LKAB is working to make the production process of iron ore pellets fossil-free. In particular, this thesis project focuses on the pellet induration stage and addresses the mathematical optimization of the process. READ MORE

4. 3. Bricklaying robot for installation ofrefractory material in grate-kiln systems

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Johan Johansson; [2023]
   Keywords : ;

   Abstract : LKAB is Europe’s biggest producer of iron pellets and is constantly trying to improvetheir production methods and maintenance work to reduce downtime and increasethe production volume. A critical step of the pellets production is the reduction stepinvolving the roterary oven which is one of the most prone steps in the productioncycle of needing maintenance work. READ MORE
