The preparation of forgings before forging includes selection of raw materials, calculation of materials, blanking, heating, calculation of deformation force, selection of equipment and design of molds.Lubrication method and lubricant should be selected before forging.

Forging materials involved in a wide range, both a variety of brands of steel and superalloy, and aluminum, magnesium, titanium, copper and other non-ferrous metals;There are once processed into different sizes of bar and profile, and a variety of specifications of ingot;In addition to a large number of domestic materials suitable for China's resources, there are materials from abroad.Most of the forging materials have been included in the standard, there are also a lot of research and development, trial and promotion of new materials.As is known to all, the quality of forging products is often closely related to the quality of raw materials, so workers in forging factories must have the necessary knowledge of materials and be good at choosing suitable materials according to the requirements of the process.

Reduce friction, not only can save energy, but also can improve the life of the mold.As the deformation is relatively uniform, it is helpful to improve the microstructure of the forging products. One of the important measures to reduce friction is to use lubrication.Due to the different forging and working temperature of forgings, the lubricant used is also different.Glass lubricant is used for forging high temperature alloy and titanium alloy.For hot forging of steel, water-based graphite is a widely used lubricant. For cold forging, due to high pressure, phosphate or oxalate treatment is required for forging.
