Objective
The technical objective of this project is to investigate the interaction between deoxidised steel (low- and high-alloyed steel grades) melts and oxidic materials during the process of ladle metallurgy. Finally steel grade specific slag systems and the ladle glaze technique will be optimised in view of low re-oxidation potentials and a low tendency for uncontrolled inclusion formation. In this way steel cleanliness can be improved through lower amounts of non-metallic inclusions, which has a beneficial impact on productivity and quality of steel products.
The formation and modification of inclusion by ladle slags, ladle lining and ladle glaze will be studied in detail. These aspects will be investigated on selected steel grades both under process and laboratory conditions. Through the close cooperation between industrial partners and universities optimised slag compositions and treatment strategies will be developed and verified in practice. European steelworks will finally profit from these project results.
