Different Forging Deformation Methods When Forging Forgings
Different forging deformation methods, such as free forging, open die forging, closed die forging, extrusion, top upsetting, high-speed die forging, rolling, etc., its essence is to apply different forms of thermal and mechanical conditions to the blank through the corresponding forging equipment processing and die, so as to produce different physical fields and organizational properties evolution processes. The same forging, the choice of deformation mode is reasonable, the quality of the forging is very different, the wrong choice may make the forming process can not be achieved, not very reasonable choice will make forming difficult, prone to many quality defects.

The forging process parameters of deformation temperature, deformation speed and deformation degree are obviously directly related to the quality of forgings. For example, for ingots or certain materials, it is necessary to compact the structure and refine the grains by deformation. If the amount of forging deformation is small, the expected effect cannot be obtained; some non-ferrous metals, especially high-strength aluminum alloys and magnesium alloys, require Small deformation speed and appropriate degree of deformation, and suitable for forming on a press, which helps to avoid cracks.

What is the organizational stress of crane wheel forgings?
If there is phase change in the cooling process of crane wheel forgings, it will produce tissue stress. As with heating, the tissue stress is also caused by the change of the specific volume of the tissue before and after the phase change, and the outer layer and the heart phase change are different.
