摘要： C-shaped inductors for induction heating a heated steel material that is carried via table rollers. Each C-shaped inductor includes a C-shaped iron core having a pair of legs facing each other by sandwiching a gap through which the heated steel material passes, and heating coils wound around the pair of legs of the C-shaped iron core. A ring-shaped iron core for restricting induced currents generated in the heated steel material is disposed near the C-shaped inductors, and the heated steel material passes through the gap of each C-shaped inductor.

摘要： A material 1 to be shaped is reduced and formed by bringing dies with convex forming surfaces, when viewed from the side of the transfer line of the material 1, close to the transfer line from above and below the material 1, in synchronism with each other, while giving the dies a swinging motion in such a manner that the portions of the forming surfaces of the dies, in contact with the material 1, are transferred from the upstream to the downstream side in the direction of the transfer line.

摘要： A lower surface cooling box 12 is arranged between transfer rolls 11 on a runout table 3 and an upper cooling box 14 moving freely is arranged at a position corresponding to the cooling box 12 to eject cooling water to the steel strip symmetrically in the vertical direction. The steel strip passes the center of converge of cooling water from upper and lower surfaces of the steel strip. A water breaking roll 16 is provided elevating freely at least at the outlet side rotating at the same peripheral speed as the transfer rolls and is rotated to lower concurrently with passing of the steel strip top at the cooling apparatus. The upper cooling box is also lowered concurrently to cool the steel strip.
