Large forgings are objects in which metal is pressed to form the required shape or suitable compression force through plastic deformation. Strength is typically achieved through the use of a hammer or pressure. The casting process creates a refined grain structure and improves the physical properties of the metal.
In the actual use of components, a correct design can make the particle flow in the direction of the main pressure. The manufacture of large forgings is one of the key technologies for major equipment manufacturing. Its quality directly affects the overall level and operational reliability of major equipment. It is the basis for the development of industries such as electric power, shipbuilding, metallurgy, petrochemicals, heavy machinery, and national defense. And it is a prerequisite for the advanced equipment manufacturing industry. With the continuous development of China's equipment manufacturing industry, the demand for large and large forgings will continue to expand.
Oversized forgings are the classification of forgings, large tonnage, and large-size forgings, including rings, shafts, cakes, and other forgings. Forgings need to be consistent from piece to piece, without any porosity, excess space, inclusions, or other blemishes. Components produced by this method have a high ratio of strength to weight. Components are commonly used in aircraft construction. The advantages of forgings are stretchable length, shrinkable cross section; shrinkable length, stretchable cross section; changeable length, and changeable cross section. The types of forgings are free forging/hand forging, hot die forging/precision forging, top forging, rolling forging, and die forging.
