コイル。 In a coil made of a movable single-turn heating conductor that heats the surface of a large-diameter roll in which narrow circumferential grooves are formed at predetermined intervals in the longitudinal direction, the heating conductor is cut from a thick plate material so that the cross-sectional shape is the inner circumference. It is a hollow ring that has a convex shape in cross-section and is formed by a square-shaped ring protruding in the direction, and the open outer circumferential direction is closed with a flat band material, and the base of the convex shape is sufficiently spaced from the roll circumferential surface. The length of the protrusion is set so that the protrusion is in a position where In addition, the wall thickness of the tip wall is set to be sufficiently large, and a magnetic material is attached to both sides of the protrusion with a thickness that is less than the difference in thickness from the base.This coil has a circumferential groove for heating the roll surface.
