Ring forgings
A forging is an object in which metallic is subjected to strain and fashioned to the required form or suitable compressive pressure via plastic deformation. This pressure is usually accomplished via the use of a hammer or pressure. The casting manner builds fantastic particle constructions and improves the bodily homes of the metal. In the realistic use of components, a right diagram can make certain that the particle drift is in the course of the principal pressure. The blessings of forgings encompass stretchable size and shrinkable cross-section; Shrinkable length, stretchable cross-section
Ring forgings are a product in the forging enterprise and a kind of forging. It is a round object made of metallic billets (excluding plates) that are subjected to exterior pressure and molded via plastic deformation to reap splendid compressive force. This pressure is normally completed thru the use of a hammer or pressure. The forging procedure builds outstanding particle constructions and improves the bodily homes of the metal. Circular forgings are ubiquitous in each day lifestyles and are an industrial product.
The application fields of ring forgings are:
Diesel engine ring forging: a kind of diesel engine forging, diesel engine diesel engine diesel engine is a kind of power machinery, it is commonly used as an engine. Taking large diesel engines as an example, the forgings used include cylinder heads, main journals, crankshaft end flange output end shafts, connecting rods, piston rods, piston heads, crosshead pin shafts, crankshaft transmission gears, ring gears, intermediate gears and oil dyeing pump bodies.
Marine ring forgings: Marine forgings are divided into three categories, main engine forgings, shaft forgings and rudder forgings. Main engine forgings are the same as diesel engine forgings. Shafting forgings include thrust shaft, intermediate shaft, stern shaft, etc. Rudder forgings include rudder rods, rudder posts, rudder pins, etc.
Ordnance ring forgings: Forgings occupy an extremely important position in the weapons industry. In terms of weight, 60% of the tanks are forgings. Barrels, muzzle brakes and tails in artillery, rifled barrels and three-sided bayonets in infantry weapons, rocket and submarine deep-water launchers and mounts, stainless steel valve bodies for high-pressure coolers for nuclear submarines, shells, gun shells, etc., are all forged products. In addition to steel forgings, weapons are also made from other materials.
Petrochemical ring forgings: Forgings have a wide range of applications in petrochemical equipment. Such as the manhole and flange of the spherical storage tank, the various tube sheets required for the heat exchanger, the forging cylinder (pressure vessel) of the butt welded flange catalytic cracking reactor, the cylinder section used in the hydrogenation reactor, and the top cover, bottom cover, head, etc. required by fertilizer equipment are forgings.
Mining ring forgings: According to the weight of the equipment, the proportion of forgings in mining equipment is 12-24%. Mining equipment includes: mining equipment, hoist equipment, crushing equipment, grinding equipment, washing equipment, sintering equipment.
Nuclear power ring forgings: Nuclear power is divided into two categories: pressurized water reactor and boiling water reactor. The main large forgings of nuclear power plants can be divided into two categories: pressure shells and reactor internal components. The pressure shell contains: cylinder flange, nozzle section, nozzle, upper cylinder, lower cylinder, cylinder transition section, bolt, etc. The internal components of the pile work under severe conditions such as high temperature, high pressure, strong neutron irradiation, boric acid water corrosion, erosion and hydraulic vibration, so 18-8 austenitic stainless steel should be selected.
Thermal power ring forgings: There are four key forgings in thermal power generation equipment, namely the rotor and guard ring of the turbine generator, and the impeller and steam turbine rotor in the steam turbine.
Hydropower ring forgings: Important forgings in hydroelectric power station equipment include large shafts of hydroelectric turbines, large shafts of hydroelectric generators, mirror plates, thrust heads, etc.
