The manufacturing process of ring forgings has the following characteristics and difficulties:

         1. Continuous deformation and small reduction: In the ring rolling process, the deformation of the blank is continuous and the reduction is small, which makes process control more difficult and requires precise control of parameters such as temperature, pressure, and deformation.

         2. High precision requirements: Due to the requirement of high dimensional and shape accuracy in all directions for ring forgings, precise molds and equipment are required, and there are also high requirements for the quality and stability of raw materials.

         3. Large machining allowance: Compared with free forging, ring forgings have a larger machining allowance and require larger cutting amounts and longer processing times to complete, which increases manufacturing costs and production cycles.

         4. Difficulty in controlling process parameters: In the production process of ring forgings, it is necessary to control multiple process parameters, such as temperature, pressure, deformation speed, deformation degree, etc. These parameters affect each other and are difficult to control. Advanced process control technology is needed.

         5. High production cost: Due to the complex manufacturing process of ring forgings, high-precision equipment and high-quality raw materials are required, resulting in high production costs and the need for effective cost control measures.

The main issues that need to be addressed during the manufacturing process include:

         1. Control deformation process: The manufacturing process of ring forgings involves complex deformation processes, which require the use of advanced process control technology to ensure the stability and accuracy of the deformation process.

          2. Improve dimensional accuracy: In order to meet the customer's requirements for dimensional accuracy of ring forgings, high-precision molds and equipment need to be used, while optimizing process parameters.

         3. Optimize machining allowance: By optimizing process parameters and adjusting mold design, reduce machining allowance, improve material utilization, and reduce manufacturing costs.

         4. Quality control: Through strict quality control measures, ensure the quality and stability of raw materials and the stability of the process, thereby improving the quality level of ring forgings.
