6. A Study of EAF High-Chromium Stainless Steelmaking Slags Characteristics and Foamability
Sammanfattning : A good slag practice is essential for production of a high-quality stainless steel. In addition, the electrical and material efficiency of the electric arc furnace (EAF) can considerably be improved by a good slag practice. The metallurgical properties of the slag are strongly influenced by its high-temperature microstructure. LÄS MER
7. A Study of the Behavior of Foaming Slag in Steelmaking
Sammanfattning : The thesis presents a fundamental study on some aspects regarding foaming slag. In today’s society, the requirements on environmental impact and energy consumption are increasing. LÄS MER
8. Energy and environmental optimization of some aspects of EAF practice with novel process solutions
Sammanfattning : The objective of the present thesis is to optimize the electric arc furnace (EAF) practice from an environmental view point. Two aspects that meet the requirements of the secondary steelmaking industries today, viz. LÄS MER
9. Influence of alumina on the zinc slag fuming processes : an experimental study on physical properties and leaching behaviour of the generated fayalite-type slag
Sammanfattning : Recycling of secondary raw materials by non-ferrous metal producers is steadily increasing. These materials inevitably introduce various impurities to the production furnaces, which can change the chemical composition, and thereafter, the physical and chemical properties of the products and by-products of the operation.

10. Some aspects of recycling of rest products and slag foaming in the EAF during stainless steel production
Sammanfattning : An efficient stainless steel making industry is defined by different factors such as an efficient utilisation of energy in the Electric Arc Furnace (EAF). This requires a good by slag foaming practice and an utilisation of waste products from own production facilities. LÄS MER
