Stabilizing deformation: ensuring that the workpiece deforms stably in the pass and obtains the required geometric shape and size. Controlling deformation: controlling or forcing the torsion or bending deformation of the workpiece to move in a certain direction. Improving quality: removing iron oxide scale, making the surface of the workpiece smoother, and increasing the surface strength of the workpiece, thereby improving the quality of the steel.
