Description
Summary:The tundish prevents unsteady flow affecting on the steel cleanness and temperature. The presented article offers a new design of a ladle shroud (LS) with three holes placed in a special dome (separating the steel flow) steeped in a metal bath. Various options of the LS construction were analysed, as well as its positioning in the tundish in relation to its longitudinal axis. The conducted numerical simulations enabled to assess the impact of the designed ladle shroud on the flow of liquid steel through the tundish. The results showed that the best option is to use the LS with two larger holes and one smaller which activates the flow structure and reduces the rate of the liquid steel velocity in the tundish, limiting the flow turbulence.
