The purpose of forging
Forging can use pressure on metal billets to cause plastic deformation and change their mechanical properties. Forging can eliminate metal porosity. Holes improve the mechanical properties of forgings. [2] Forgings have the following uses:
① General industrial forgings refer to civil industries such as machine tool manufacturing, agricultural machinery, agricultural tool manufacturing, and bearing industry.
② Forgings for hydroelectric generators, such as main shafts and intermediate shafts.
③ Forgings for fossil-fuel power station, such as rotor, impeller, retaining ring spindle, etc.
④ Metallurgical machinery, such as cold rolling rolls, hot rolling rolls, and herringbone gear shafts.
⑤ Forgings for pressure vessels, such as cylinder bodies, kettle ring flanges, and heads.
⑥ Marine forgings, such as crankshafts, stern shafts, rudder stock, thrust shafts, and intermediate shafts.
⑦ Forging and pressing mechanical equipment, such as hammer heads, hammer rods, hydraulic press columns, cylinder bodies, axle press columns, and cylinder bodies.
⑧ Module forgings are mainly forging dies used for hot die forging hammers.
⑨ Forgings used in the automotive industry, such as left and right steering knuckles, front beams, and couplers, account for 80% of their mass in automobiles according to statistics.
⑩ Locomotive forgings, such as axles, wheels, leaf springs, and crankshafts, account for 60% of their mass in locomotives.
⑪ Military forgings, such as gun barrels, door bodies, bolt brackets, and traction rings, account for 65% of their mass in tanks.
