How are high precision forgings made
The heat during the forging of locomotive support seat must be strictly controlled
The heat transfer coefficient between the block die forging slab and boiling water has an effect on the cooling deformation
The polygonal sub-grain boundary gradually replaces the thermal working structure in the process of die forging deformation
For the high quality products that can be brought by the improvement of technology in die forging processing
After processing, the die forging must pass quality inspection before it can be put into use
