Electromagnets applied to thin steel plate

To depress the vibration and meandering of a thin steel plate in a steel making plant, electromagnets are applied to the plate. According to the results of numerical calculation, the different pole arrangement is superior to the same pole arrangement for the vertical position control, though the same pole arrangement is superior to the different pole arrangement for the lateral position control. There is no significant difference in the electromagnetic forces obtained at room temperature as compared to 700/spl deg/C. However, the investigation shows that the smallest electromagnetic forces are obtained at the 765/spl deg/C.
