Ring forgings are a product in the forging industry, a type of forgings. It is a ring-shaped object in which a metal blank (not including a plate) exerts an external force and becomes a suitable compression force through the requirements of plastic deformation. This force is typically achieved through the use of a hammer or pressure. The forging process creates a fine grain structure and improves the physical properties of the metal. Ring forgings can be seen everywhere in daily life and are an industrial product.
A kind of diesel engine forgings. Diesel engine. Diesel engine is a kind of power machinery. It is often used as an engine. Taking a large diesel engine as an example, the forgings used include cylinder head, main journal, crankshaft end flange, output end shaft, connecting rod, piston rod, piston head, crosshead pin shaft, crankshaft transmission gear, ring gear, intermediate gear and oil dye pump More than ten kinds of body and so on.
Marine forgings are divided into three categories, main engine forgings, shafting forgings and rudder forgings. The main engine forgings are the same as the diesel engine forgings. Shafting forgings include thrust shafts, intermediate shafts and stern shafts. Rudder forgings include rudder stock, rudder post, rudder pin, etc.
Forgings occupies an extremely important position in the weapons industry. By weight, 60% of the tanks are forgings. 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.
Forgings are widely used in petrochemical equipment. Such as manholes and flanges of spherical storage tanks, various tube plates 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.
Calculated by equipment weight, the proportion of forgings in mining equipment is 12-24%. Mining equipment includes: mining equipment, hoisting equipment, crushing equipment, grinding equipment, washing equipment, sintering equipment.
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, cylinder transition section, 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.
There are four key forgings in thermal power generation equipment, namely the rotor and guard ring of the steam turbine generator, and the impeller and the steam turbine rotor in the steam turbine.
The important forgings in the equipment of hydroelectric power station include hydraulic turbine shaft, hydraulic turbine generator shaft, mirror plate, thrust head, etc.
