DORCO: What are the rolling processes for annular forgings?

1、 Radial rolling

Radial rolling is the most fundamental ring rolling process. During the processing, the ring wall is compressed radially, and the metal extends along the tangential direction; Even if the axial direction is not restricted by the rolling mill, the width expansion of the ring wall is extremely small. This process is mainly suitable for ring components with rectangular cross-section, groove cross-section, and cross cross-section. Its equipment structure is relatively simple and the investment cost is low, making it suitable for large-scale production of basic components. It should be noted that due to the surface deformation characteristics of metal deformation, the end face of the ring formed by radial rolling may have pits.

The vertical ring rolling machine launched by DORCO is designed specifically for optimizing the radial rolling process. Its compact structure and convenient operation enable efficient batch rolling of common cross-section rings, helping customers achieve stable production with low investment.

2、 Radial axial rolling

In order to improve the quality of the end face and meet the requirements of complex section forming, radial axial rolling technology has emerged. This process adds end face rollers on the basis of radial rolling, so that while the ring is thinned radially, the axial height is also rolled, thereby obtaining a straight end face. By controlling the wall thickness and height separately through a pair of radial rollers and a pair of axial rollers, not only does it reduce the number of mold changes and significantly save mold costs, but it also significantly improves the forming accuracy. This process is particularly suitable for annular forgings with large wall thickness or complex cross-sectional shapes.

The DORCO horizontal ring rolling machine adopts advanced radial axial composite rolling technology and is equipped with a precision CNC system, which can stably process high difficulty ring parts such as wind turbine flanges and aviation ring forgings. Its excellent rigidity and control accuracy ensure that every finished product meets the strict standards of customers.

Whether it is radial rolling for efficiency or radial axial rolling for complex working conditions, DORCO can provide corresponding equipment and technical support to help customers optimize processes and enhance product competitiveness.
