Forging classification:

1. The marine forgings

Marine forgings divided into three categories, the host forgings, axis forgings and rudder system forgings. Host forgings and diesel engine forgings. Axis forgings have thrust shaft, intermediate bearing stern shaft, etc. Rudder system forging a pole, rudder steering column, rudder pimple.

2. Petroleum chemical engineering forgings

Forge a wide range of applications in oil chemical equipment.  Such as spherical tanks of manhole, flange, all kinds of heat exchanger tube plate, butt weld flange catalyzing &cracking reactor in the whole barrel (pressure vessels), hydrogenation reactor used the tube's, chemical fertilizer equipment need cover, sealing that top all is forging wear-resisting rod.

3. The plane forgings

According to the weight calculation, the plane of around 85% of the component is forging. The plane engine turbine disc, rear axle neck (hollow shaft), leaf, the beam wing, the fuselage of stiffened plate, round rib support, the landing gear on the inside and outside the cylinder body is involved in the plane of the importance of safety forgings. The plane forgings multi-purpose high strength wear resistance, corrosion resistant alloy, titanium alloy, nickel-based alloy and other precious materials manufacturing. In order to save material and energy saving, in forging the most used die forging or learn a lot from die forging press to production. Automobile forging press weight calculate, car 71.9% of forgings. The basic car by body, trunk, engine, front axle and rear axle, frame, gearbox, transmission shaft, steering system 15 components comprise automobile forging is characteristic of the complex shape, light weight, and poor working conditions, the safety degree high requirements. If the car engine by use of the crankshaft, connecting rod, the camshaft, front axle needed beam, before knuckles, driving axle use of half axle, half a collar tube, the bridge driving gear etc, all are the cars in the safe operation of the security key forgings.

4. Nuclear power forgings

Nuclear power is divided into two types of boiling water reactor and automatically. The main nuclear power plants can be divided into large forgings island and pile of inner component two kinds big. Island including: cylinder pipe flanges, mouth nozzle, the upper part, and the cylinder, the lower the cylinder body, barrel transition section, bolts, etc. Pile of inner component is in high temperature and high pressure, strong neutron irradiating water corrosion and erosion, boric acid and hydraulic shock severe conditions of the job so should choose 18-8 austenitic stainless steel to make.

5. Hydropower forgings

Hydraulic power station equipment is important forging a turbine large shaft, hydraulic generators big axis, lens board, thrust top.
