Development and application of intermixed length and composition variation model in continuous slab casting processes during a grade transition

工程科学学报, 2021
Based on a developed physical model during the mixing process in the tundish and the liquid pool of the strand, intermixed length and composition variation model have been established during steel grade changes in the continuous slab casting processes ...

Improving the Cleanness of Low‐Carbon Tube Steel Under Steel Plant Conditions

Advances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.
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.

Physics‐Informed Data‐Driven Prediction of Submerged Entry Nozzle Clogging with the Aid of Ab Initio Repository

steel research international, Volume 96, Issue 9, Page 462-475, September 2025.
A physics‐informed data‐driven model is developed to assist steelmakers in minimizing production interruptions caused by submerged entry nozzle (SEN) clogging. To further enhance accuracy, methodology involving use of ab‐initio repository is developed. “Clogging Factor” parameter is proposed to monitor the output generated .

NUMERICAL MODELING OF STEEL FLOW IN A MULTI-STRAND CONTINUOUS CASTING TUNDISH

Acta Metallurgica Slovaca, 2014
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.
