Product Description

Product Description

Custom large diameter forging ring

Forging ring have widespread applications in the mechanical processing industry, primarily used in critical areas that need to withstand high loads and dynamic stresses, such as bearings, gearboxes, and connectors. Owing to their exceptional strength and toughness, 42CrMo forged rings are particularly suited for key components in heavy machinery, aerospace, and petrochemical equipment. Additionally, forged rings are commonly employed in rotating machinery like turbines and compressors to achieve efficient power transmission and distribution. Their main role in these applications is to provide stable support and reliable connections, ensuring the safe operation and long service life of the entire mechanical system.

General Production Process of Forging Ring

- Open Die Forging: Gradually form the metal billet into the desired ring shape through hammering and rolling. This step may require multiple iterations to achieve the target shape and dimensions.

- Ring Rolling: Use specialized ring rolling machines for continuous rolling, gradually expanding the ring diameter and reducing wall thickness until the design specifications are met.

Heat Treatment

- Normalizing/Annealing: Improve internal material structure and enhance mechanical properties through normalizing or annealing treatments.

- Quenching + Tempering: Perform quenching to increase hardness, followed by tempering to reduce internal stresses and improve toughness.

Machining

Turning and Milling: Remove excess material to form the basic contour and prepare for subsequent precision machining. This stage leaves appropriate machining allowances for finishing steps.

Company Profile

Who We Are

Established in 2002, Luoyang Wangli Heavy Machinery Co.,ltd. focus on metal research and mining machinery spare parts. Our factory located in Luoyang, one of important base for heavy machinery in China. 2 factories over an area of 13,300 square meters, based on 100+ sets of equipment, our production capacity reaches 12000 Tons/Year. has passed ISO 9001 quality managment system certification in 2015.
Our mainly products: dragline excavator spare parts,rotary kiln spare parts, large modulus gear (gear shaft), gearbox ect. 40+ patents with over 45 years experience to help focus on improve the service life of spare parts. We belive that more than 80% reason of mechanical parts' working life depends on hot processing (steel making/forging/casting/welding/heat treatment). Eight material engineers will control the quality from the original resource.
 
Over the past 15+ export experience, we have served 200+ compaies in 50+ countries and regions, During these times, three international key projects, such as segment girth gear used in the Suez Canal in Egypt.
We believe that innovation is the key to success and attracts talents who can think differently. Together, we can make a real difference.
