1. Influence of Ladle-slag Additions on BOF-Process Parameters
Sammanfattning : The influence of ladle-slag additions on the BOF-process performance were investigated in plant trials. The aim of the study was to recycle ladle slag from secondary steelmaking to the LD-converter to save lime and improve the slag formation. LÄS MER
2. Fine particle emissions and slag formation in fixed-bed biomass combustion : aspects of fuel engineering
Sammanfattning : There is a consensus worldwide that the share of renewable energy sources should be increased to mitigate climate change. The strive to increase the renewable energy fraction can partly be met by an increased utilization of different biomass feedstocks. LÄS MER
3. Mineral Reactions and Slag Formation During Reduction of Olivine Blast Furnace Pellets
Sammanfattning : The present work focuses on mineral reactions and slag formation of LKAB olivine iron ore pellets (MPBO) subjected to reducing conditions in the LKAB experimental blast furnace (EBF). The emphasis is on olivine reactions with surrounding iron oxides. Many factors influence the olivine behaviour. LÄS MER
4. 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.

5. Co-injection of basic fluxes or BF flue dust with PC into a BF charged with 100% pellets : effects on slag formation and coal combustion
Sammanfattning : Based on 100% pellets operation at BF No. 3 at SSAB Tunnplåt in Luleå a new pellet with CaO/SiO2=1 was developed during early nineties. The pellet showed good results in metallurgical laboratory test but caused slag formation problems in the bosh. LÄS MER
