Forging process generally consists of the following processes, namely, selecting high quality billet blanking, heating, forming and cooling after forging. The forging process includes free forging, die forging and membrane forging. In production, different forging methods are selected according to the quality of forgings and the quantity of batches produced.

Free forging is widely used to forge single and small-batch forgings with simple shape because of its low productivity and large processing allowance, but its simple tools and versatility. Free forging equipment includes air hammer, steam-air hammer and hydraulic press, which are suitable for the production of small, medium and large forgings respectively. Die forging has high productivity, simple operation and easy to realize mechanization and automation. Die forgings have high dimensional accuracy, small machining allowance and more reasonable distribution of fiber structure, which can further improve the service life of parts.

The basic process of free forging: when forging freely, the shape of forgings is gradually forged by some basic deformation processes. The basic processes of free forging include upsetting, drawing, punching, bending and cutting.

Function:

Flange is a part connected between shaft and shaft, which is used to connect pipe ends. It is also used in the import and export of equipment, which is used to connect two equipment, such as reducer flange.

When the pump and valve are connected with the pipeline, the parts of these equipment are also made into corresponding flange shape, also known as flange connection. Where bolts are used around two planes to connect joints that are closed at the same time, they are generally referred to as "flanges", such as the connection of ventilation pipes, which can be called "flanges".

Because of its good comprehensive performance, flange is widely used in chemical engineering, construction, water supply, drainage, petroleum, light and heavy industries, refrigeration, sanitation, water heating, fire protection, electric power, aerospace, shipbuilding and other basic projects.
