The forging of large aluminum forgings not only needs to meet the required part shape and size, but also is important to break the as cast structure, refine the grain, uniform structure, forging shrinkage cavity, air hole, shrinkage porosity and other defects, so as to improve the internal quality o

The purpose of heat treatment for large forgings after forging is to refine the coarse grains caused in the forging process, eliminate work hardening and residual stress, reduce hardness, improve cutting performance, prevent white spots from forming inside the forgings, ensure the required metal str

The cooling modes of large forgings mainly include water cooling (including water spray cooling), oil cooling, air cooling (natural air cooling and air blast cooling), gap cooling (water air, water oil, oil air) and spray cooling. The commonly used quenching media for large forgings are water, oil a

High-temperature alloys are iron, nickel and cobalt-based metal materials that can work for a long time at temperatures above 600°C and under certain stresses, with excellent high-temperature strength, good resistance to oxidation and thermal corrosion, good fatigue properties, fracture toughness an

Traditionally, high-temperature alloy materials can be classified in three ways: by matrix element type, alloy strengthening type, and material forming method.1、According to the type of matrix elements(1) Iron-based high-temperature alloysIron-based high-temperature alloy can also be called heat-res

All kinds of degradation rates of materials are accelerated under high temperature environment. In the process of use, it is easy to cause organizational instability, deformation and crack growth under the effect of temperature and stress, and oxidation corrosion of material surface.1. High temperat

Superalloy is a kind of metal material based on iron, nickel and cobalt, which can work for a long time under high temperature above 600 ℃ and certain stress; It has high high temperature strength, good oxidation and corrosion resistance, good fatigue performance, fracture toughness and other compre

Heavy forgings are classified as large tonnage and large size forgings. Including ring, shaft, cake and other forgings. Each piece of forging shall be consistent without any porosity, excess space, inclusion or other defects. The components produced by this method have a high ratio of strength to we

Heavy forgings are objects in which metal is pressed to shape the required shape or suitable compression force through plastic deformation. Strength is typically achieved by the use of a hammer or pressure. The casting process creates a refined granular structure and improves the physical properties

In recent years, the trend of large-scale wind power industry has driven the demand for large forgings to grow continuously, while large MW capacity companies with excellent technical strength and good layout are the first to benefit. A large number of forgings are used in wind turbine generators. T

With the development of the times, the precision requirements for workpieces and forgings in industrial production are getting higher and higher. Ordinary rough machining is difficult to meet the personalized needs of different customers. Therefore, in the process of making forgings, most processing

Aluminum alloy forging temperature range and heating specificationStarting from improving plasticity and reducing deformation resistance, we hope to increase the heating temperature of metal as much as possible; However, in order to ensure product quality and avoid heating defects, the heating tempe
