Abstract: A roller leveler for flattening a metal sheet or plate having a cut-sheet form includes leveling rolls disposed in a staggered state on upper and lower sides of a pass line and configured to sandwich and flatten the metal sheet while pressing it therethrough, a hydraulic pressing cylinder for pressing the metal sheet via the leveling rolls, intermediate rolls set in contact with the respective leveling rolls from outside and larger in diameter than the leveling rolls, and a drive unit for rotating the intermediate rolls. The roller leveler causes the drive unit to rotate the intermediate rolls and transmits the driving force to the leveling rolls to pass the metal sheet while causing the pressing cylinder to press the metal sheet via the leveling rolls.

Abstract: A roller leveler is provided having a substantially uniform pitch of leveling rolls arranged in a zigzag manner. The roller leveler is provided with a first roll group having first leveling rolls arranged with a pitch “P1” in the carrying direction of a steel plate, a second roll group having five pieces of second leveling rolls which are arranged with the pitch “P1” in the carrying direction of the steel plate and have a zigzag arrangement with respect to the first leveling rolls, a first retract mechanism for retracting the middle first leveling rolls from the pass line, and second retract mechanisms for retracting the pairs of end second leveling rolls from the pass line. The second roll group has third leveling rolls disposed with the pitch “P1” in the carrying direction of the steel plate with respect to the outermost second leveling rolls.

Abstract: A leveling technique that produces a high degree of flatness of strips and gives strips a characteristic such that parts cut from the strips by etching do not warp. Also, a method of leveling strips including the steps of rectifying a trip by tensioning and bending the strip with a tension leveler.

Abstract: A pickling method which can effectively conduct pickling, and can shorten pickling time. The strip is plastic elongated by 0.1 to 10% before it is introduced into the pickling tank to form cracks. The strip is bent so that a surface strain of the strip is 0.2 to 1 times the plastic elongation during dipping the strip in the acid solution of the pickling tank, thereby making the cracks open and close, and supply of a fresh acid solution and expelling of an exhausted acid solution may be effectively conducted. Scale always contacts with a fresh acid solution by this bending operation, so that a scale dissolution reaction proceeds fast, thereby being capable of shortening the pickling time.
