Drive Rings
Longer-Lasting “Forging-Rolling” Drive Rings
Drive rings are consumable forgings that must withstand enormous impact forces during pile-driving operations.
Unlike pure free forging, we use a “forging-rolling” process to manufacture drive rings. First, large-deformation multi-directional free forging breaks up coarse grains in the steel billet. Then, radial-axial rolling is applied for further forming. Radial-axial rolling is a continuous forming process, and under strong rolling forces, the metal fibers align with the circumferential direction of the workpiece, forming continuous flow lines. This enhances the impact resistance of the drive rings, extends their service life, and allows them to complete more pile-driving tasks.
More Cost-Effective Drive Rings
Compared with conventional free forging, the forging-rolling process requires fewer heating cycles and provides higher forming precision. This means we can not only complete manufacturing faster, but also reduce machining allowances and energy consumption, offering advantages in cost control and rapid delivery.
Ready for Larger Offshore Wind Turbines
Offshore wind turbines are growing bigger, with tower base flanges now over 12 meters in diameter. This calls for larger steel pile sections. Traditional free forging struggles to make extra-large drive rings because of press limitations, but our forging-rolling process can produce drive rings of almost any size without such restrictions.
