<p>PROBLEM TO BE SOLVED: To provide moving induction heating of a steel plate 10 being drawn for grain refining, capable of easily supplementing deficient holding power even while using a holding device 41 at a gripping part 40.SOLUTION: A gripping part 40 having a holding device 41 for holding the edge of a steel plate 10 in the longitudinal direction across the full width is also provided with a hooking device 42 for hooking a bore hole (11) at the edge of the steel plate 10 in the longitudinal direction. The hooking device 42 forms a protrusion as a part of the holding device 41, being integrated for easiness in use. The gripping part 40 includes a hook-added part (52) for holding the central part in the full width at the edge of the steel plate 10 in the longitudinal direction which is provided with a hooking device-integrated holding devices 41+42, and a hook-less part (51) adjacent to the edge in the width direction, away from the central part, is provided with the holding device 41 without the hooking device 42, so that the function for correcting the bend and the warp of the steel plate 10 can be enhanced. The gripping part 40 has a holder 43 made of nonmagnetic material for holding the holding device 41 and the hooking device 42, so that grain refining can be sufficiently performed over the region close to the edge of the steel plate 10. Consequently the cut-off amount can be reduced.</p> |
