Forging equipment category and standard name

Compared with castings, metal after forging to improve its organizational structure and mechanical properties. The method of forging the cast structure after hot working due to the deformation of the metal after deformation and recrystallization, so that the original coarse dendrite and columnar grains become finer grain, equiaxed recrystallized structure of uniform size, so that the segregation of the original ingot, loose, porosity, slag and other compaction and welding, the organization becomes more closely to improve the mechanical properties of plastic and metal.
Mechanical properties of castings forgings mechanical properties lower than the same material. In addition, to ensure the continuity of the metal forging fibrous tissue, fibrous tissue and make forging forging consistent appearance, the metal flow lines intact, to ensure parts with good mechanical properties and long life using precision forging, cold extrusion , temperature extrusion process to produce forgings, castings are unmatched
Forging metal was pressured by the shape or suitable plastic deformation of the compression force required to shape objects. Typical of this power by using a hammer or pressure to achieve. Forging process built fine grain structure and improves the physical properties of the metal. In reality, the use of components in the design to make a correct particle flow in the direction of the main stress. Casting is casting metal forming objects using a variety of methods to get and that is a good liquid metal smelting, with casting, injection, inhalation or injection of other casting methods in pre-prepared mold, cooled by the falling sand, clean-up and after treatment, the obtained a certain shape, size and performance of the object.
