The concept of “active tundish slag” aims definitely at improving of steel cleanliness by tailoring a proper tundish slag. In this project, active tundish metallurgy was investigated and assessed. Computation of phase diagrams was used as an appr

In the continuous-casting mold, the mold powder in contact with the liquid steel surface forms a liquid slag layer. The flow along the steel-slag interface generates shear stress at the interface, waves, and leads to fingerlike protrusions of liquid

With the single hot thermocouple technique (SHTT) the solidification behavior of metallurgical slags has been studied by in situ observation, constructing time– temperature–transformation (TTT) or continuous-cooling-transformation (CCT) diagrams.

The main problem related to the development of fluorine-free mould powders for slab casting is effectively controlling the heat transfer between the steel shell and mould. In commercial mould powders crystallization of cuspidine (Ca4Si2O7F2) from mou

The elimination of fluorine from slags is necessary because F-bearing materials pollute the environment and cause machinery corrosion at steelworks. Regarding the development of F-free mould slags for slab casting, the main problem is how to control
