Influence of Oxygen Contamination on the Genesis of Nonmetallic Inclusions in a Microalloyed Steel
Oxygen contamination during melting of steels strongly affects the evolution of nonmetallic inclusions. Controlled remelting experiments, combined with SEM/EDS analysis and thermodynamic simulations, reveal how reoxidation promotes the transformation of alumina‐based inclusions into complex FeO–MnO oxides and other interactions.

NUMERICAL MODELING OF STEEL FLOW IN A MULTI-STRAND CONTINUOUS CASTING TUNDISH
The tundish is an important unit in a continuous casting device. The flow of the liquid steel in tundishes has a crucial influence on quality of steel, which is nowadays defined by the number and size of non-metallic inclusions.

Improving the Cleanness of Low‐Carbon Tube Steel Under Steel Plant Conditions
Reducing the number of nonmetallic inclusions in high‐quality steel rolled products is of great importance for all steel plants. One of the ways to decrease the size and quantity of alumina and silicate nonmetallic inclusions could be suppressing their formation during steel tapping from the BOF converter to the ladle.
