Because the Corten B channel steel is an asymmetrical rolled piece, the temperature is low in the thinner part of the waist, and the temperature in the thicker part of the leg is high, which results in the upward bending of the leg during cooling.
In order to straighten the Corten B channel steel, first of all, the cooling of the Corten B channel steel should be controlled well, and the temperature difference and bending degree should be reduced. In addition, the cooling of the left and right sides should be uniform, and the lateral bending should be reduced, and the local hard bending should be reduced at the same time.
