Product Description

Piercer plug used for piercing mill process
Brief introduction
Rotary piercing is a very fast and dynamic rolling process that cross rolls the preheated billet between two barrel-shaped rolls at a high speed. The cross rolling causes high tensile stresses at the center of the billet. The design of the piercer rolls causes the metal to flow along the roll and over a piercer point as it exits the process. The piercer point is a high-temperature, water-cooled alloy tool designed to allow the metal to flow over it as a pipe shell forms from the rotary process. Once the pierced pipe shell is produced, it is immediately transferred to the floating mandrel mill.
