Forgings are workpieces or blanks obtained by forging and deforming metal blanks. The plastic deformation of metal blank can change its mechanical properties by using pressure. According to the temperature during billet processing, forgings can be divided into cold forging, warm forging and hot forging. Cold forging is usually processed at room temperature, while hot forging is processed at a higher recrystallization temperature than the metal blank.
1. Ordinary industrial forgings refer to civil industry, such as machine tool manufacturing, agricultural machinery, agricultural tool manufacturing and bearing industry.
2. Hydraulic generator forgings such as main shaft and intermediate shaft.
3. Rotor, impeller, retaining ring spindle and other thermal power station forgings.
4. Metallurgical machinery, such as cold roll, hot roll, herringbone gear, etc.
5. Forgings are used for pressure vessels, such as cylinder, kettle ring flange and head.
6. Marine forgings such as crankshaft, tail shaft, rudder stock, thrust shaft and intermediate shaft.
7. Forging mechanical equipment such as hammer head, hammer rod, cylinder body of hydraulic press, cylinder body of wheel axle press, etc.
8. Modular forging mainly composed of modular die forging hammer.
9. According to statistics, forged parts account for 80% of the quality of left and right steering knuckle, front beam, coupler and other automotive industry forgings.
10. Locomotive forgings, such as axle, wheel, leaf spring, locomotive crankshaft, etc. According to statistics, the quality of locomotive forgings accounts for 60%.
