WHAT IS THE RING FORGING PROCESS

Ring forging is a manufacturing process used to produce seamless rings with desired dimensions and properties. It involves the shaping of metal through localized compressive forces applied to a heated workpiece. Here is an overview of the ring forging process:

Material Selection: The process begins with selecting the appropriate material for the desired ring. Common materials used in ring forging include carbon steel, alloy steel, stainless steel, and various non-ferrous metals.

Billet Heating: The selected material is heated to a specific temperature range, typically above its recrystallization temperature, to improve its plasticity and make it easier to shape. Heating can be done in furnaces or using induction heating methods.

Preforming: Once the billet reaches the desired temperature, it is placed on a die and subjected to an initial shaping process. Preforming can be performed using various techniques, such as open die forging, closed die forging, or rolling.

Ring Rolling: The preformed billet is then moved to a ring rolling machine, which consists of two or more rotating rolls. The rolls exert pressure on the billet to deform it into the desired ring shape. The process is typically conducted at elevated temperatures to reduce the forging forces and enhance material flow.

Ring Expansion: If necessary, the ring may be subjected to additional expansion processes, such as mandrel expansion or radial-axial rolling, to achieve the desired dimensions, thickness, and contour.
