1. A Study of the Initial Mould Filling during Up-hill Ingot Casting
Abstract : The fluid flow in the mould during up-hill teeming is of great importance for the quality of the cast ingot and thereby the quality of the final steel products. At the early stage of the filling of an up-hill teeming mould, liquid steel flows with a high velocity from the runner into the mould. READ MORE

2. Formation of non-metallic inclusions and the possibility of their removal during ingot casting
Abstract : The present study was carried out to investigate the formation and evolution of non-metallic inclusions during ingot casting. Emphasize have been on understanding the types of inclusions formed and developed through the casting process and on the development of already existing inclusions carried over from the ladle during casting.

4. Water-based Tape Casting of Ceramics and Fabrication of Ceramic Laminates
Abstract : The objective of the work presented in this dissertation has been twofold: to develop a water-based system for tape casting and to build laminar structures from the tapes. A set of requirements on the binder was specified and latexes were identified as suitable for water-based tape casting, mainly owing to their low viscosity and high polymeric content. READ MORE

5. Inclusion Motion under a Swirl Flow in the Continuous Casting Process and Wire Feeding in the Induction Furnace
Abstract : The thesis includes the studies of two phenomena related to continuous casting. One subject is the inclusion motion in the submerged entry nozzle (SEN) and mold when using a swirl flow. The swirl flow is generated in a SEN by using an electromagnetic swirl flow generator (EMSFG). READ MORE
