• In twin roll casting process, two difficulties must be conquered. One is the formation of a wide molten metal film and the other is the controlling and stabilizing of flow between two rolls.Regarding the first problem, application of an alternating magnetic field on molten metal film is proposed. In order to confirm this idea, the effect of a high frequency magnetic field on suppression of film shrinkage is calculated by use of a mathematical model. This model based on water model experiments has been developed to take into account the magnetic pressure acting on molten metal films.The second problem is tackled with imposing a direct magnetic field. It is found that the surface wave on the molten metal puddle between two rolls causes a saw edge shape and that magnetic field can suppress the saw edge shape by experiments using tin. The effect of magnetic field intensity on suppression of saw edge shape is evaluated.
