Ring Forging

Hot forging process forms the core of our ring forgings, endowing them with exceptional structural integrity and uniform grain distribution. Crafted from high-grade carbon steel or alloy steel, these rings undergo strict heat treatment to enhance hardness and toughness. Advanced CNC machining ensures precise dimensional control, meeting tight tolerances for critical mechanical applications. Whether used in heavy machinery, automotive components, or industrial equipment, our ring forgings set a benchmark for reliability and durability.

Engineered for high-load environments, our ring forgings feature excellent load-bearing capacity and resistance to wear, corrosion, and high temperatures. The seamless, defect-free structure minimizes stress concentration, ensuring stable performance even under extreme working conditions. Available in various diameters, wall thicknesses, and material grades, they adapt to diverse application needs—from bearing races in wind turbines to transmission rings in construction machinery, providing consistent performance across industries.

Understanding that each project has unique requirements, we offer fully customized ring forging solutions—from material selection to geometric design and surface treatment. Our technical team collaborates closely with clients to optimize forging parameters, ensuring the final product aligns perfectly with functional and structural needs. With a proven track record in aerospace, energy, and marine sectors, our ring forgings combine precision engineering with manufacturing flexibility, empowering customers to achieve innovation and efficiency in their applications.

FAQ

What is the difference between forging and casting?

Forging: It is the process of transforming a solid from one shape to another. Casting: It is the process of transforming a shapeless liquid metal into a solid with a shape. The so-called casting is the process of casting molten metal into a model to obtain a casting. The casting profession focuses on the metal melting process and the control of processes during the casting process. Forging is a plastic forming process in the solid state, which can be divided into hot processing and cold processing. Forgings include extrusion, drawing, roughening, punching, and so on. Casting is a solid liquid solid process, while forging is a solid to solid process where a solid can change its shape into another shape at high temperatures. There are still differences in the shape process and process of the two.

How to choose high-quality circular forgings?

In the quality inspection of forgings, there are mainly external observation methods and internal inspection methods. The appearance method, as the name suggests, is to observe the appearance of the product, such as the shape, geometric dimensions, surface condition, etc. of the forging, in order to understand whether it meets the standards and whether there are external defects. Specifically, it is to check whether the external dimensions of the forging meet the specifications and whether there are defects on the surface, such as cracks, wrinkles, bubbles, indentations, pits, impurities, scratches, etc. on the surface of the forging. Internal testing mainly involves analyzing the chemical composition, macroscopic and microscopic structures, and mechanical properties of forgings. This inspection process requires the use of specialized instruments for high magnification inspection, with the aim of checking for any phenomena such as fractures. and shrinkage within the forging, as well as defects such as dendrites and white spots, disordered flow lines, and through flow. It also includes the tensile strength, ductility, hardness, plasticity, and heat resistance temperature of the forging.

What are the characteristics of the forging process for circular blank forgings?

The forging process of circular forgings mainly consists of the following processes: pier roughening, elongation, punching, and expanding. The difference between free forging and ring rolling processes is mainly in the process of expanding holes. In the production of rina forainas, free foraing is usually used to expand the hole with a horse screw, while ring rolling is mainly used to expand the hole with rolling.
