1. 1. The effect of recycling and processing routes on recrystallization in a secondary 3xxx aluminium alloy

   University essay from Jönköping University/JTH, Material och tillverkning

   Author : Anton Rolseth; [2023]
   Keywords : Aluminium alloys; sheet metal forming; grain boundary segregation; recrystallization; Zener pinning; casting; rolling;

   Abstract : Aluminium alloys have the possibility to be infinitely recycled. By only generating 5% of the emissions compared to primary aluminium, great CO2 savings can be made. One of the issues in manufacturing components entirely from post-consumer scrap is the presence of trace elements and impurities. Such elements can be Fe, Cu, Cr, P and Pb. READ MORE

3. 2. Improved Furnace Control : System identification and model predicative control of Outokumpu’s reheating furnace

   University essay from Uppsala universitet/Signaler och system

   Author : Oscar Holmqvist; [2023]
   Keywords : Systeem Identification; Model Predictive Control;

   Abstract : This thesis investigates one option for improving the control of a reheating furnace used in heating steel slabs before hot rolling; an essential part of the steel manufacturing process. The furnace consumes a significant amount of energy, leading to high cost and high carbon dioxide emissions. READ MORE

4. 3. Simulation of Rolling Mill to Computeand Improve Load Distribution

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

   Author : Pontus Darth; [2021]
   Keywords : Finite Element; Simulation; Hot rolling mill; SSAB; Swerim AB; Roll Spallings; Spallings; Roll Failure;

   Abstract : This master thesis was done at Swerim AB in cooperation with SSAB and the Technical University of Luleå in the purpose of preventing spalling problems in hot rolling mills. Spallings are a fatigue damage that occurs on the rolls due to extreme loads and unfavorable conditions between the rolls in a mill. READ MORE

5. 4. The Effect of Twinning on the Mechanical Properties of Alloy 825

   University essay from KTH/Materialvetenskap

   Author : Sanna Kylström; [2019]
   Keywords : ;

   Abstract : Twinning is a known phenomenon in material science, but how is it connected with grain size and yield strength? Investigations are made on alloy 825 with light optical microscopy for 19 samples to calculate the twin fraction and grain size. Afterwards, the results are compared to yield strength throughout tensile tests. READ MORE

6. 5. Energy Flow Analysis of Muesli Production : To Identify Cleaner Production Measures

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Anuj Dahiya; [2018]
   Keywords : Efficiency; Energy Losses; Improvements; Environmental performance;

   Abstract : Production of muesli is an energy intensive process which consumes enormous amount of energy invarious forms. In this study, energy flow accounting tool has been employed which is a valuable tool for mapping and quantifying the energy flows within a specific system such as a nation, city or factory. READ MORE
