Casting and casting are two different processes. Casting is the transformation of an unformed liquid metal into an unformed solid. The pressure rating of casting valves is generally relatively low. Most calibers are above DN 50. The casting process is mainly formed by high temperature casting. It can refine the particles in the part. Casting valve is casting, generally used for high-grade pipeline, smaller diameter, generally lower than DN50.
Free casting is a processing method that uses impact force or pressure to deform the metal in all directions between the upper and lower anvil surfaces. Compared with the casting blank, free forging eliminates the shortcomings of shrinkage, shrinkage, porosity, etc., so that the blank has higher mechanical properties. Forging shape simple, sensitive operation. Therefore, it is particularly important in the manufacture of heavy machinery and important parts.
Free forging contains artificial casting and mechanical equipment casting two categories, in the modern industrialization of heavy machinery manufacturing, its existence plays an important role. And the formation of the forging style and scale contains the technical level of the operator's resolution. Free casting machines and equipment are divided into two categories: forging hammer and hydraulic press.
The forging hammers used in production include air hammers and steam-air hammers. Some factories also use spring hammers, splint hammers, lever hammers and steel wire hammers with simple structure and less capital. The hydraulic press is a method of producing large forgings by deforming the billet under the static pressure of the liquid.
