1. Viscosities of complex slags and the impact of the same on foaming in EAF
Sammanfattning : .... LÄS MER
2. A Study of EAF Austenitic and Duplex Stainless Steelmaking Slags Characteristics
Sammanfattning : The high temperature microstructure of the solid phases within the electric arc furnace (EAF) slag has a large effect on the process features such as foamability of the slag, chromium recovery, consumption of the ferroalloys and the wear rate of the refractory. The knowledge of the microstructural and compositional evolution of the slag phases during the EAF process stages is necessary for a good slag praxis. LÄS MER
3. Interfacial Phenomena in Two-Phase systems: Emulsions and slag Foaming
Sammanfattning : In the present work studies were performed to provide understanding for further model development of the two-phase phenomena, film formation from o/w emulsions and slag foaming.The drying of o/w emulsions of different oil viscosities on hydrophobic and hydrophilic substrates was studied.

4. A study of some aspects of gas-slag-metal interactions : Towards dynamic process model and control
Sammanfattning : The present thesis deals with the development of a new type of dynamic model for metallurgical reactors. It also covers some of the theoretical aspects of steelmaking that is necessary to include in such an application. The thesis consists of modeling work, high temperature experiments and cold model experiments. LÄS MER
5. Study on some phenomena of slag in steelmaking process
Sammanfattning : The present work is to study slag phenomena in steelmaking process. In order to attain thegoal, a number of high temperature experiments and simulation experiments were carried out. Four master slags were used to study the effect of CaF2 on slag viscosity. LÄS MER
