Large scale forging is one of the main methods for producing rough forgings and parts in mechanical manufacturing, often divided into free forging, die forging, etc. Compared with other processing methods, forging processing has the following characteristics:

1.Improve the internal structure and mechanical properties of tube sheet forgings. After forging processing, the micro-structure and properties of the rough of the tube sheet forging are improved and enhanced. Forging processing can eliminate defects such as porosity, shrinkage, and dendritic crystals inside the metal ingot. Due to the plastic deformation and recrystallization of the metal, coarse grains can be refined to obtain a dense metal structure, thereby improving the mechanical properties of the tube sheet forging. When designing parts, selecting the correct direction of force and fiber structure can improve the impact resistance of forgings.

2.The utilization rate of materials is high. The plastic forming of metals mainly relies on the rearrangement of the relative positions of the metal's structural structure, without the need to cut off the metal.

3. High productivity. Forging processing is generally carried out using a press machine and a forging hammer for forming processing.

4.The accuracy of blanks or forgings is relatively high. By applying advanced technology and equipment, it is possible to achieve minimal or no cutting machining.

5. The metal materials used for forging should have good plasticity, so that they can undergo plastic deformation without rupture under external forces. Among commonly used metal materials, cast iron is a brittle material with poor plasticity and cannot be used for forging. Copper, aluminum, and their alloys in steel and non-ferrous metals can be processed under pressure in either the cold or hot state.

Due to the above-mentioned characteristics of tube sheet forging, rough forgings should be used for processing. Therefore, forging processing is widely used in industries such as mechanical manufacturing, mining, light industry, heavy industry, power, and chemical industry.
