Optimization of the steel flow in the two-strand tundish using different geometry of impact pad

Abstract

One of the primary factors affecting the quality of continuously cast billets is the way the steel flows and mixes in the tundish of Continuous Steel Casting (CSC) machine. This is of particular importance in the case of continuous billets. The article presents the results of model tests of identifying the mechanism of liquid steel flow through a tundish under the influence of the applied arrangement of the working space. Two models of turbulence inhibitors and an impact pad with the surface of a sphere segment were used for the research. The tests were carried out with the use of the physical water model of the CSC device, and the obtained results were verified by numerical methods.
