Where are forgings used in all industries?

During the use of forgings, the technical requirements are very strict, requiring each piece to be consistent, without any porosity, excess space, inclusions or other defects. This method produces components that have a high ratio of strength to weight. These elements are commonly used in aircraft structures. Of course, this does not mean that these forgings are not allowed to be used in other industries. Obviously, in all walks of life in industrial production, the use of forgings is very extensive.
1. Aircraft forgings: According to weight, about 85% of the components on the aircraft are forgings. Aircraft engine turbine disc, rear journal (hollow shaft), blade, wing SPAR, fuselage rib plate, wheel support, landing gear inside and outside cylinder body are important forgings related to aircraft safety.
Two, diesel engine forgings: diesel engine is a kind of power machinery, it is commonly used as an engine. Take large diesel engine as an example, the forgings used are cylinder head, spindle neck, crankshaft end flange output end shaft, connecting rod, piston rod, piston head, crosshead pin shaft, crankshaft drive gear, ring gear, intermediate gear and dye oil pump body, etc. More than ten kinds.

3. Marine forgings: Marine forgings are divided into three categories: main engine forgings, shafting forgings and rudder forgings. Main engine forgings are the same as diesel engine forgings. Shafting forgings include thrust shaft, intermediate shaft and stern shaft. Rudder system forgings include rudder rod, rudder post, rudder pin, etc.

Forgings: Forgings occupy an extremely important position in the ORdnance industry. By weight, 60% of the tanks are forgings. The barrel, muzzle brake and gun tail of artillery, ribo-rived barrel and three-edge bayonet of infantry weapon, rocket and submarine depth charge launcher and fixed seat, stainless steel valve body for nuclear submarine high pressure cooler, shell and bullet, etc., are all forged products. Weapons are made of materials other than steel forgings.

Five, petrochemical forgings: Forgings have a wide range of applications in petrochemical equipment. For example, the manhole and flange of the spherical storage tank, the tube plate needed by the heat exchanger, the whole forging cylinder body of the welding flange catalytic cracking reactor (pressure vessel), the cylinder section used by the hydrogenation reactor, the top cover, the bottom cover and the sealing head required by the fertilizer equipment are forgings.

Vi. Mining forgings: According to the weight of equipment, the proportion of forgings in mining equipment is 12-24%. Mine equipment includes: mining equipment, winch equipment, crushing equipment, grinding equipment, washing equipment, sintering equipment.

Seven. Nuclear power forging: Nuclear power is divided into pressurized water reactor and boiling water reactor. The major forgings of nuclear power plant can be divided into two categories: pressure shell and reactor internals. Pressure shell includes: cylinder flange, nozzle section, nozzle, upper cylinder, lower cylinder, cylinder transition section, bolts, etc. The inner components of the reactor are in high temperature, high pressure, strong neutron amplitude, boric acid water corrosion, erosion and hydraulic vibration and other severe conditions to work, so 18-8 Austenitic stainless steel to make.

Eight, thermal power forgings: there are four key forgings in thermal power generation equipment, namely the rotor and guard ring of the turbine generator, as well as the impeller and turbine rotor in the turbine.

Nine, hydropower forgings: hydraulic power station equipment in the important forgings are turbine shaft, turbine generator shaft, mirror plate, thrust, etc.
