Analysis and Improvement of Forge Cracks on Gear Steel 20CrMnTiH Used for the Automobile

摘要：

Hot head forge cracks of gear steel φ80 mm 20CrMnTiH which is produced by 50t EBT+LF+CC+vD+650 rolling process have been analyzed. Surface blowhole and subsurface crack are the main causes. Preventing continuous casting powder scull is an effective method for solving head forge cracks.
