1. On deoxidation practice and grain size of austenitic manganese steel
Sammanfattning : The exceptional wear resistance and work hardenability, place Hadfield steel as one of themost important materials for manufacturing cast components used in the mining, crashing,drilling, and excavation industries. In all metallic alloys used for component casting, themechanical properties are highly influenced by the microstructure of the material. LÄS MER
2. On particles and slags in steel casting
Sammanfattning : Hadfield steel is widely accepted as one of the most important steel alloys utilized in industrial applications where high impact strength and wear resistance is required. Like in most metallic alloys used for component casting, the mechanical properties of Hadfield steel are directly connected with the microstructure of the material. LÄS MER
3. Slag, Steel, Ladle and Non-metallic Inclusions Equilibria in an ASEA-SKF Ladle Furnace
Sammanfattning : This study explores the possibility of prediction and modification of some of the physicochemical properties of non-metallic inclusions by considering top slag-steel-ladle equilibria in an ASEA-SKF ladle furnace. To test the reliability of an available computational thermodynamic computer program, the first sub project was done. LÄS MER
4. Wettability and Agglomeration Characteristics of Non-Metallic Inclusions
Sammanfattning : In this thesis, both the wettability and the agglomeration characteristics of non-metallic inclusions in liquid iron/steel were studied by using both experimental results and thermodynamic considerations. The mechanisms of the wettability of different types of inclusions were discussed. LÄS MER
5. Formation and Chemical Development of Non-metallic Inclusions in Ladle Treatment of Steel
Sammanfattning : The present study was carried out to investigate theformation and chemical development of non-metallic inclusionsduring ladle treatment of steel.To begin with, an investigation of the deoxidation processand the impact of aluminium addition was carried out. For thispurpose, a new experimental setup was constructed. LÄS MER
