Forging production is one of the main processing methods for the provision of mechanical parts in the machinery manufacturing industry. Through forging, not only can get the shape of mechanical parts, but also to improve the internal metal structure, improve the mechanical properties of metal and physical properties. Generally on the force, the requirements of high important mechanical parts, most of the use of forging production methods. Such as turbo-generator shaft, rotor, impeller, blade, retaining ring, large hydraulic press column, high pressure cylinder, rolling mill roll, internal combustion engine crankshaft, connecting rod, gear, bearing, and national defense industry and other important parts, produce.
Therefore, forging production is widely used in metallurgy, mining, automobile, tractor, harvesting machinery, petroleum, chemical, aviation, aerospace, weapons and other industrial sectors, is in daily life, forging production also has an important position.
In a sense, the annual output of forgings, the proportion of forging in the total forging of forgings, and the size and ownership of forging equipment, to a certain extent, reflects the industrial level of a country.
