Two Multi-Directional Die Forging Methods for Ball Valve Bodies
Ball valve bodies are critical components in valves, traditionally manufactured through casting. However, casting is prone to defects such as porosity, shrinkage, and dendritic formation, which can prevent valves from meeting performance requirements in harsh operating conditions. To enhance the mechanical properties of ball valve bodies, researchers and manufacturers have turned to forging techniques, particularly free forging and die forging. These methods, however, generate substantial material...
