Quality Ring Rolling Machine & Vertical Ring Rolling Machine factory

As industry trends toward larger scales and higher performance, the production of semi-finished materials mirrors this shift. Large semi-finished components—such as those used in wind turbine generators and critical parts for nuclear reactors—are still predominantly manufactured via open-die forging processes, though certain applications can now be partially replaced by ring rolling using radial-axial ring rolling mills. Traditional Manufacturing Method: Large Open-Die Forging Presses: These components are commonly produced using mandrel forging, which relies on large open-die forging presses with forging forces adjusted according to workpiece specifications. The starting stock is prepared from a raw material block matching the required weight, with additional material allowance to compensate for losses. When metallurgical properties permit, hollow ingots may also be used. Once the starting stock is ready, it is forged over a mandrel to achieve the specified dimensions. Mandrel forging is a time-consuming process: the workpiece must be rotated incrementally during repeated forging strokes, and intermediate reheating is often required to offset temperature loss and maintain proper forging temperatures. Radial-Axial Ring Rolling Mill: The ring rolling process offers distinct advantages for precisely forming such rotationally symmetric workpieces and can, under suitable conditions, partially replace mandrel forging. The radial-axial ring rolling mill is a well-suited piece of equipment for large ring forging applications. Compared with open-die forging, the ring rolling process demonstrates favorable applicability for large, rotationally symmetric workpieces with sufficient central bore diameters. It enables more precise forming and can serve as a viable alternative to conventional mandrel forging for the production of such large rings. Focusing on large ring forging, the advantages of the radial-axial ring rolling mill are evident from both metallurgical and economic perspectives: 1,By first preparing a pre-forged ring blank, the high forging ratio required for large rings is ensured, thereby enhancing the metallurgical properties of the product. 2,It enables precise final sizing and rolling of large rings, ensuring dimensional accuracy that meets the stringent demands of large-scale ring components. 3,The equipment specifications align well with large ring production requirements, with investment scale appropriately matched to the initial wall thickness of the ring blank. 4,By replacing the traditional final forging stage, the process reduces raw material consumption in large ring production, contributing to better control of overall manufacturing costs. The Duolek 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. Welcome domestic and foreign customers to inquire and negotiate.

From the first batch of environmental components being taken offline until now, the equipment has maintained a stable operating state, which gives us confidence in our subsequent production plans.
