1. Abatement of Chromium Emissions from Steelmaking Slags - Cr Stabilization by Phase Separation
Sammanfattning : Chromium is an important alloying element in stainless steel but also environmentally harmful element. A number of mineralogical phases present in the slag matrix can contain chromium and lead to chromium leaching. LÄS MER
2. A study of slag-steel-inclusion interaction during Ladle treatment
Sammanfattning : The thesis is based on two supplements with two major objectives. In the first supplement equilibrium top slag-steel bulk and inclusions-steel bulk were investigated by comparison between calculated and measured oxygen activity values. This was done by applying different oxide activity models for slags combined with thermodynamic calculations. LÄS MER
3. A study on molten steel/slag/refractory reactions during ladle steel refining
Sammanfattning : .... LÄS MER
4. An Experimental Study to Improve the Casting Performance of Steel Grades Sensitive for Clogging
Sammanfattning : In this study, the goal is to optimize the process and to reduce the clogging tendency during the continuous casting process. The focus is on clogging when the refractory base material (RBM) in the SEN is in contact with the liquid steel. LÄS MER
5. The Submerged Entry Nozzle : A Study of how to Reduce Decarburization and Clogging
Sammanfattning : During continuous casting the submerged entry nozzle (SEN) is one of the critical points. This since sequence casting is favourable, clogging of the SEN results in fever sequences or aborted castings. In this study the preheating of SEN has been evaluated at different steel plants. LÄS MER
