"It took only 3 months to successfully develop the world's first 3D additive manufacturing piercer roll. Sinosteel XTMMC is such a 'hard core'!" A large domestic seamless steel pipe customer praised the finished product across the acceptance site of the processing workshop of Sinosteel XTMMC’s Special-Shaped Company. This is another masterpiece launched by the company following the successful development of the upgraded version of NM rolls for the fourth-generation seamless rolling mill. It also marks a more solid step in promoting the replacement of new material piercer rolls.

As an important part of strategic emerging industries, additive manufacturing integrates computer-aided design, material processing and molding technologies, and manufactures physical objects through software and numerical control systems. It is known as one of the disruptive technologies that can lead industrial changes.

It is reported that the piercing rolls used in the domestic seamless steel pipe industry mostly adopt the overall forging production process of low alloy or medium carbon steel. In the process of use, due to poor bite and poor wear resistance, it is easy to cause problems such as frequent roll changes and low rolling efficiency. Selecting "safe, reliable, stable and consistent" high-performance piercing rolls is the key to ensuring the efficient operation of seamless steel pipe enterprises. Relying on its proprietary technology and core capabilities, Sinosteel XTMMC’s Special-Shaped Co., Ltd. has continuously optimized the material process on the basis of summarizing the manufacturing experience of the upgraded version of NM rolls used in the previous four generations of seamless rolling mills, innovatively used the 3D additive manufacturing technology, independently designed and developed a 3D additive manufacturing piercing roll that integrates precise control of the working layer, high fatigue resistance, wear resistance, good bite and other characteristics, which is highly praised by the customer.
