The preparation of aluminum alloy forgings before forging includes the selection of raw materials, calculation, blanking, heating, deformation, equipment and mold design. Before forging, the lubrication method and lubricant should also be selected.

Forging materials have a wide range of surfaces, including various brands of steel, high-temperature alloys, aluminum, magnesium, titanium, copper and other non-ferrous metals; processed into bars and profiles of different sizes at one time, as well as ingots of various specifications; in addition to a large number of domestic materials suitable for Chinese resources In addition to materials, there are also foreign materials. Most forging materials have been incorporated into national standards, and many of them are new materials developed, tested and promoted. As we all know, the quality of products is often closely related to the quality of raw materials, so forging personnel must have the necessary material knowledge and be good at choosing the most suitable material according to the process requirements.

The calculation of materials and feeds is one of the important links to improve material utilization and achieve blank refinement. Too much material will not only cause waste, but also increase the wear and energy consumption of the mold. If there is no surplus, it will increase the difficulty of process adjustment and increase the waste rate. In addition, the quality of the feed end face will also affect the quality of the process and forgings.

The purpose of heating is to reduce the forging deformation force and improve the plasticity of the metal. But heating also brings a series of problems such as oxidation, decarburization, overheating and overheating. Accurate control of initial forging and terminal forging temperature has a great influence on the microstructure and properties of products. The flame furnace has low heating cost and strong applicability, but the heating time is long, it is easy to oxidize and decarburize, and it is necessary to continuously improve the working conditions. Electric induction heating has the advantages of fast heating and less oxidation, but it has poor adaptability to product shape, size and material changes.
