The most popular conical roll piercing process is adopted. The diameter of the roll gradually increases from the inlet to the outlet, which is more conducive to metal flow and extension, thereby greatly reducing the tangential shear stress during the deformation process, controlling the rotary transverse forging effect, and is more suitable for piercing high-alloy steel and ultra-thin-wall steel pipes.
