Effects of Tundish Cover Powder and Teeming Stream on Oxidation Rate of Molten Steel in Tundish.
The oxidation rate of the molten steel covered with the tundish cover powder and the molten steel being teemed was measured and the reaction mechanism was investigated as a basic study to quantify the oxidation rate of molten steel at different parts in an actual tundish.

Bubble Characteristics Required for the Complete Removal of Alumina Inclusions from Steel Melts
Illustration of burst (or collapsed) microbubbles of argon trapped within a “flash‐frozen” sample of low melting point alloy (freezing point +57 °C), following rapid dipping and withdrawal of a cooled copper bar (≈at −100 °C) from the bath of the molten metal alloy. There, the submerged gas injection system is subjected to rapidly shearing metal flows,

Enhanced Inclusion Removal from Steel in the Tundish [PDF]
The objective of this project was to develop an effective chemical filtering system for significantly reducing the content of inclusion particles in the steel melts exiting the tundish for continuous casting. This project combined a multi-process approach that aimed to make significant progress towards an "inclusion free" steel by incorporating several

The accuracy of computational models depends on uncertainty of the input data. This work conducts a sensitivity analysis of the CON1D model of solidification heat transfer in a steel continuous slab‐casting mold. Results identify the parameters which are critical to defect‐relevant outputs: mold heat flux, shell thickness, surface temperature, and mold

The tundish plays an important role in the challenging task of a “clean steel” production process. The flow of the liquid steel in tundish has a crucial influence on non-metallic inclusions distribution and separation.

The task of the tundish is to supply and distribute the molten steel with the similar temperature and the similar inclusion mass concentration to the continuous casting mold. But it is difficult for the asymmetric tundish to accomplish this task.

Hydrodynamic conditions occurring in the tundish are strictly connected with the equipment of its working zone. On such conditions influence also many factors such as: the amount of steel present in the working zone, the velocity of steel casting.
