When industrial manufacturing moves towards the "big" era: analysis of the applicability of horizontal ring rolling machines!

The current industry is developing towards large-scale and high-performance, and the production of semi-finished materials is also showing this trend. Large semi-finished products such as wind turbine components and key components of nuclear reactors are still mainly produced by free forging technology, and some can be replaced by radial axial ring rolling technology.

Traditional manufacturing method: Large free forging press forging:

This type of component commonly uses the core shaft forging process, which requires the use of a large free forging press, and the forging pressure is adjusted according to the workpiece specifications. The blank is prepared from raw material blocks of matching weight, with additional materials reserved to compensate for losses. Hollow steel ingots can also be used when metallurgical performance meets standards. After the blank is made, it is forged and processed to the preset size through the core shaft.

Core shaft forging takes a long time, and the workpiece needs to be rotated multiple times for forging. During the process, intermediate heating is required to compensate for temperature loss and ensure that the forging temperature meets the standard.

Radial axial ring rolling machine:

Rolling ring technology has specific advantages in precision forging of such symmetrical workpieces, and can partially replace core shaft forging when conditions are met.

The radial axial ring rolling machine is a suitable equipment for forging large ring parts. Compared with free forging, its ring rolling process shows better applicability in forging large, rotating center symmetric workpieces with sufficient inner holes, and can achieve more accurate forming. It can be used to replace traditional core shaft forging process for the production of such large ring parts.

Focusing on the forging of large ring components, the advantages of radial axial ring rolling machines are reflected in metallurgy and economic benefits as follows:

One is to prepare pre forged ring blanks first to ensure the high forging ratio required for large ring components and improve the metallurgical properties of the product;

Secondly, it can complete the final precision forging and rolling of large ring components, ensuring that the dimensional accuracy meets the standard and meets the strict requirements of large ring components;

Thirdly, the equipment specifications can match the production of large ring components, and its investment scale is suitable for the initial wall thickness of the ring blank;

Fourthly, replacing the traditional final precision forging process can reduce the consumption of raw materials for the production of large ring components, which is beneficial for controlling production costs.

The DORCO D53KF series horizontal ring rolling machine adopts CNC technology, which can achieve simultaneous radial and axial rolling of ring components. When operating, simply input parameters such as the size and material grade of the ring, ring blank, and rolling mill, and the equipment will automatically execute the rolling process. The size of the ring and the operating status of the machine will be displayed in real-time on the screen.

In addition, the company has also developed bulging machines, loading and unloading machines, operating machines, forging hydraulic presses, rotary forging machines, and large-scale ring automation production lines that are compatible with large-scale ring rolling machines. These devices help to improve the level of production automation, enhance environmental quality and production efficiency, and reduce labor costs for enterprises.
