Abstract

PURPOSE:To make the temperature distribution uniform in the axial direction of a hollow roll by arranging a plurality of solenoid coils in the axial direction between the hollow roll and a fixed shaft and inserting an iron core between the fixed shaft and the solenoid coil. CONSTITUTION:A plurality of solenoid coils 8 are arranged between a hollow roll 5 and fixed shaft 1 with an iron core 9 inserted between the fixed shaft 1 and the solenoid coil 8. With this constitution, a closed magnetic circuit is formed with the iron core 9 and the roll 5 when each solenoid coil 8 is excited. The magnetic flux induced with each solenoid coil 8 flows through the entire roll 5 to generate heat in the roll 5 and to make the temperature distribution uniform in the axial direction of the roll 5.
