Steel Forged Metal Products

Aircraft forgings

Calculated by weight, about 85% of the components on the aircraft are forgings. Aircraft engine turbine discs, rear journals (hollow shafts), blades, wing spars, fuselage ribs, wheel brackets, and inner and outer cylinders of landing gear are all important forgings related to aircraft safety. Aircraft forgings are mostly made of high-strength wear-resistant and corrosion-resistant aluminum alloys, titanium alloys, nickel-based alloys and other precious materials. In order to save materials and energy, most aircraft forgings are produced by die forging or multi-directional die forging presses. According to the weight of automobile forging, there are 71.9% of forgings on automobiles. A general automobile is composed of 15 components such as the body, the box, the engine, the front axle, the rear axle, the frame, the transmission, the transmission shaft, and the steering system. The characteristics of automobile forgings are complex appearance, light weight, poor working conditions, and safety. High standard. For example, the crankshafts, camshafts, front beams, steering knuckles, axle shafts used in the rear axle, half-shaft sleeves, transmission gears in the axle box, etc. used in the automobile engine are all related to the safe operation of the automobile. Key forgings for security.

Folding diesel engine

Diesel engines are a type of power machinery. Take large diesel engines as an example. Forgings include cylinder heads, main journals, crankshaft end flanges, output end shafts, connecting rods, piston rods, piston heads, crosshead pins, crankshaft transmission gears, and ring gears. , Intermediate gears and oil-dyeing pump bodies, etc.

Folding marine forgings

Marine forgings are divided into three categories, main engine forgings, shafting forgings and rudder forgings. Shafting forgings include thrust shafts, intermediate shafts and stern shafts. Rudder forgings include rudder stock, rudder post, rudder pin, etc.

Folding weapon forgings

Forgings occupies an extremely important position in the weapons industry. The barrels, muzzle brakes and sterns in artillery, rifled barrels and triangular bayonet in infantry weapons, rockets and submarine depth charge launchers and fixed seats, stainless steel valve bodies for nuclear submarine high pressure coolers, shells, Guns and bullets are all forged products. In addition to steel forgings, other materials are also used to make weapons.

Folding petrochemical industry

Forgings are widely used in petrochemical equipment. Such as manholes and flanges of spherical storage tanks, various tube sheets required for heat exchangers, butt-welded flanges for the whole forged cylinder (pressure vessel) of catalytic cracking reactors, cylinder sections used in hydrogenation reactors, and fertilizers The top cover, bottom cover, head, etc. required by the equipment are all forgings.

Nuclear power forgings

Nuclear power is divided into two types: pressurized water reactor and boiling water reactor. The main large forgings of nuclear power plants can be divided into two categories: pressure shell and reactor internals. The pressure shell includes: cylinder flange, nozzle section, nozzle, upper cylinder, lower cylinder, bolts, etc. The internal components of the reactor work under severe conditions such as high temperature, high pressure, strong neutron radiation, boric acid water corrosion, scouring and hydraulic vibration, so 18-8 austenitic stainless steel should be used for production.

Mine forgings

Calculated by equipment weight, mining equipment includes: mining equipment, grinding equipment, washing equipment, and sintering equipment.
