Abstract
The paper presents the results of computer simulation of steel flow in the two-nozzle tundish of a T-shaped type. The tundish is symmetrical, relative to the transverse plane. The nominal capacity of the tundish is 7,5 Mg of liquid steel. The Fluent program was used to solve the mathematical model of steel casting process. In numerical simulation for modification of steel flow in the tundish subflux controller of turbulence was used. Three variants of subflux controller of turbulence configurations in the tundish were tested. As effect of mathematical calculations liquid steel velocity, turbulence intensity, turbulent kinetic energy and characteristic of Residence Time Distribution (RTD) have been obtained.
