Abstract

In this paper, the research of steel flow characteristics using three different shapes of impact pads in a 6-strands tundish is presented.The key purpose of the research presented in this paper was to improve flow characteristics and steel temperature distribution across the whole tundish inner space with the aim of preventing erosion of the refractory lining in the upper section of the inflow area. Simulations were realized for various types and shapes of impact pads. The steel flow in the tundish was evaluated using vectors, contours, streamlines, RTD curves, and the values of minimum and maximum residence times.The results indicated that the application of different shapes of impact pads may improve the flow characteristics in terms of homogenizing residence times for the individual outlets and adjusting the proportions of the mixing zones, which has a significant effect on thermal and chemical homogenization, possibility to refine steel, i.e. purify it from non-metallic inclusions and erosion of the tundish refractory lining.
