Hot forging is the forging process above the metal recrystallization temperature. Increasing the temperature can improve the plasticity of the metal, help to improve the internal quality of the workpiece, so that it is not easy to crack. High temperature can also reduce the deformation resistance of metal and the tonnage of forging machinery required.
More +Forging is mainly classified according to forming method and deformation temperature. According to the forming method, forging can be divided into free forging, die forging, cold head forging, radial forging, roller forging, rotary forging and rolling. The deformation caused by blank under pressure is basically not subject to external restrictions, which is called free forging, also known as open forging
Aluminum alloy precision ring forgings take metal powder as raw material, and the production process of metal materials, composite materials and various products adopts mold forming and sintering. 1. The utilization rate of materials is very high, reaching more than 98%; 2. Less cutting or no cutting, low cost
Forging can eliminate the defects such as loose forging of metal forgings during smelting, and optimize the microstructure. At the same time, the mechanical properties of aluminum alloy forgings are generally better than those of castings made of the same material, because it preserves a complete metal streamline. Except for rolling plates, profiles or weldments, forgings are mainly used for important components with high mechanical load and severe working conditions.
In the production of large forgings, we should pay attention to some small and tight problems. For example, if we produce large forgings with poor dimensions, it will lead to the failure of the whole mechanical equipment, which will bring great difficulties to our future life.
After forging, the internal structure of the material becomes very firm, which significantly improves the mechanical properties of the forgings, which is also the main reason for the superior performance of the forgings. Therefore, the forgings are made by machines. At present, the so-called low corrosion method is mainly used to detect cracks and non-metallic mixtures in forgings. Different low magnification materials have different specifications and fracture tests.
