Abstract: The lateral stability of alternative horizontal levitation electromagnetic continuous casting process of aluminium sheet was analyzed by correlating the lateral electromagnetic force on the aluminium sheet to the lateral position disturbance of the sheet which was set between the side blocks. The results show that when a small disturbance occurs to the lateral position of the sheet, the unbalanced lateral force caused by disturbance will make it greater. Therefore, the lateral position of the sheet is an unstable balanced position, which explains the observation of instability in experiment. Based on the analyses, an explanation for the formation of rod after the appearance of the instability in the casting process of aluminium sheet was given.
