Ring forgings are a type of product in the forging industry, which shape the required circular object through plastic deformation by applying external force to the metal billet. According to their different manufacturing processes, circular forgings can be divided into two types: seamless and seamed.
Seamless ring forgings refer to forgings without welding or other connecting interfaces in the entire ring structure, and their manufacturing processes usually include precision casting, hot extrusion, hot rolling, cold rolling, etc. In contrast, a slotted circular forging is a circular forging formed by welding two or more parts together.
In the manufacturing process, seamless circular forgings need to go through multiple processes, such as heating, rolling, extrusion, straightening, cooling, etc., to obtain the required shape and performance. In contrast, circular forgings with seams are relatively simple, and their manufacturing processes mainly include cutting, bending, welding, and trimming.
Due to differences in manufacturing processes, seamless ring forgings typically have higher strength and longer service life, making them widely used in some high demand applications, such as aerospace, petrochemical, power, and other fields. However, slotted ring forgings are more commonly used in some low demand situations.
In general, the main difference between seamless ring forgings and slotted ring forgings lies in their manufacturing process and usage scenarios.
