AI Technical Summary
During the hot rolling process of seamless steel pipes, the end of the billet cannot completely pass through the piercing roll after contacting it, resulting in uneven deformation and affecting the performance of the steel pipe.
By adjusting the distance of the contact blocks, the piercing roller can completely pass through the tube blank and contact one side of the disc. Combined with the cylinder driving the support seat to rise, the tube blank is kept aligned with the center of the piercing roller and the disc. The rolling rod is used to assist the tube blank in rotating, ensuring uniform deformation.
This achieves uniform deformation distribution in seamless steel pipes, improves pipe performance, and avoids processing errors.
