Abstract:
The present invention relates to a straightening system and a straightening method, which can conduct straightening in conformity with the shape pattern of a material, the straightening system comprising: a cooling device for spraying a cooling fluid in a predetermined pattern, in order to cool a material that has been heated in a heating furnace and has passed through a rolling device, with regard to a plurality of areas split in the transverse direction of the material; a straightening device for straightening the material that has passed through the cooling device; a flatness gauge for measuring the flatness of the material that has passed through the cooling device; and a control unit for receiving data regarding the flatness of the material from the flatness gauge and controlling the cooling device in response thereto, thereby improving the flatness of the material. This configuration is advantageous in that the flatness of the material can be improved by setting the interval between straightening rolls and the rate of straightening in conformity with the shape pattern of the material and by controlling the cooling flow rate with regard to the transverse direction of the cooling device.
