Abstract

Controlling the melt flow and free surface motion is crucial to maintain stability of many metallurgical processes. In the direct strip casting process, a known problem is the back-flow of liquid metal into the small gap between the moving belt and the refractory. Apart from geometrical and feeding modifications reported in the literature to reduce the back-flow, electromagnetic technologies could potentially solve this issue. We investigate numerically the application of the AC magnetic field to deflect the melt from the back-flow area. Simulations show that it is possible to completely prevent the back-flow but at the expense of introducing oscillations in the shape of the cast solid sheet downstream. Combination of AC field for back-flow prevention with a static (DC) magnetic field for free surface stabilization downstream can provide a fully stable casting process.
