The behaviors of several types of inclusions on the surface of liquid steel were examined using a confocal laser scanning microscope, CLSM. While alumina inclusions are likely to attract each other, agglomerate, and grow fast by the agglomeration, th

Today, MgO-C bricks are widely used in steel industry due to their excellent resistance to slag corrosion and thermal shock increased particularly by the carbon content. The presence of carbon makes these bricks very susceptible to oxidation, leading

Steel cleanliness strongly affects the properties of the products. There is an ever increasing requirement of strict control of inclusion composition and amount during ladle treatment. A comprehensive model for inclusion development in gas stirred la

Nowadays, there are increasing demands for developing mould fluxes without fluoride due to environmental concerns. Slag bearing titanium oxide and/or boron oxide proved to be promising substitute for traditional mould fluxes with fluoride. In the pre

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.
