Forging manufacturer, forging price, forging quality

The shape size of forgings shall be in accordance with the provisions of forging drawing. If the technical conditions permit, negative tolerance forging should be adopted as far as possible in order to reduce machining allowance improve material utilization. The chemical composition of the metal shall meet the technical requirements. The mechanical tensile properties of forgings shall meet the requirements of technical conditions. In order to fully deform, the forging should have enough forging ratio the internal defects should be completely welded. The forging should have good surface quality, there should be no crack, fold, double skin other defects. Local defects shall be relief grinded, the relief grinding depth shall exceed 50% of the nominal unilateral allowance. The process of forging production should be advanced to ensure reasonable metal streamline minimum anisotropy. All kinds of test materials shall be reserved for forging according to the requirements of users for various inspection (except those that users do want samples). Necessary heat treatment should be carried out according to the requirements of technical conditions to ensure that there are no internal defects such as white spots. Users don't ask for heat treatment, but those who do need it. Forgings shall have long service life. Special forgings shall meet their special requirements.

After various forms of forging deformation corresponding heat treatment, ferrous steel nonferrous metal its alloy materials can obtain forgings with high comprehensive mechanical properties such as strength, ductility impact toughness, which are inferior to those produced by casting process cutting processing method. Therefore, in the design of all kinds of mechanical products, high-performance forgings are often used for parts with large load bearing, poor working conditions high safety reliability requirements.

Large generator rotor, retaining ring main shaft, impeller blade of steam turbine in thermal power plant; reactor shell connecting pipe of nuclear power station All the forgings have certain performance requirements, such as turbine disk, rear axle diameter, wing beam, rib plate, landing gear inner outer cylinder of aircraft engine, transmission shaft of ship, high pressure vessel valve body of oil refining chemical industry, front axle, gear shaft, gear shaft of automobile, crankshaft connecting rod of engine. They have high temperature, high pressure, high temperature, high strength, high temperature high reliability.
