For example, the size of the blank is determined according to the size, shape, etc., of the product to be forged. Sometimes it is necessary to carry out some treatments on the raw blank, such as rust removal, surface defects removal, anti-oxidation and lubrication, etc., to prepare for the subsequent forging 3.Heating processThe raw blank is heated according to the heating temperature and production time required for forging deformation. Because metals soften at appropriate high temperatures and are more prone to plastic deformation, different metal materials have their own suitable heating temperature range 3.Two, forging deformation processThe blank is plastic deformed on various forging equipment (such as hammer forging equipment, presses, etc.) to complete the basic quality requirements inside and outside the forging. This process may include several steps, such as upsetting and lengthening operations in free forging, or forming the blank by a die forging. Different forging methods (free forging, die forging, special forging, etc.) operate differently in this process, with the aim of gradually bringing the blank closer to the shape and size requirements of the final forging 3.Third, forging deformation after the processForging coolingAfter forging deformation, the cooling process of the forging is followed. Factors such as cooling speed will affect the organization and performance of the forging, and it is necessary to control the cooling method according to the material and requirements of the forging, such as air cooling, pit cooling, furnace cooling, etc.Supplementary processIn order to supplement the deficiency of the previous process, so that the forging fully meet the requirements of the forging product diagram, it is also necessary to carry out a series of processes, such as cutting and punching (for die forging parts), heat treatment, correction, surface cleaning and other processes. Sometimes, the post-forging cooling is closely combined with the heat treatment process to obtain specific forging microstructure properties. In each process, and before the forging factory, the quality inspection should be carried out, the inspection items include geometric shape size, surface quality, metallographic structure and mechanical properties, etc., according to the requirements of semi-finished products and forgings between the process to determine 3.
