As the aluminum alloy forging deformation temperature range is narrow, in order to extend the forging operation time, it should be heated to the upper limit of the allowable deformation temperature as much as possible, which requires high-precision heating furnace and temperature control instrument to control the heating temperature; Otherwise, overheating may occur.
Most aluminum alloy semi-finished products after bloom have high plasticity, and are not easy to be forged and cracked under normal circumstances; However, during the forging process, severe deformation shall be avoided to avoid excessive overflow, which will affect the structure and performance of the forging. If the operation is not paid attention to, high-speed forging (such as using a forging hammer) and large deformation shall be adopted. The heat energy transformed by a large amount of deformation energy may cause the forging temperature to exceed the upper limit of the forging temperature, causing overheating, which will result in unqualified structure and performance of the forging.
