Magnetic Damping of Liquid Steel Flows in Horizontal Single Belt Casting (HSBC)

A preliminary computational fluid flow model has been developed to simulate the magnetic braking of liquid steel on a water-cooled, rapidly moving, horizontal belt. The liquid steel issuing from the proposed vertical slot-nozzle should ideally move isokinetically with the belt during freezing. In th...

Description
Summary:A preliminary computational fluid flow model has been developed to simulate the magnetic braking of liquid steel on a water-cooled, rapidly moving, horizontal belt. The liquid steel issuing from the proposed vertical slot-nozzle should ideally move isokinetically with the belt during freezing. In this study, ANSYS Fluent 14.5 software was used to model the 3-D turbulent flow of liquid steel. A 288 core High Performance Computer cluster located at the McGill Metals Processing Centre was used for high-speed computation. The standard model was used to simulate the turbulence. Similarly, the magnetic induction method was used to calculate the induced heterogeneous magnetic field, from which the current density and electromagnetic forces produced were computed. The behavior of the proposed magnetic flow control was first validated against previous experimental work and was then applied to predict the performance of the proposed slot nozzle. The predicted results show that by applying a DC Magnetic brake to the proposed metal delivery system, near isokinetic conditions can be rapidly established.
