Abstract:The effects of forging technic parameters, such as heat up temperature of preform body, forging ratio and distortion manner, on the stick performance were studied. The experimental results show that the heating temperature of finished pormer preform body should be controlled to be lower 20−30 ℃ than transformation point, and the forging ratio should be larger than 4, then the stick has good extend performance at room temperature, satisfying the demand of Chinese Standard GB/T2965—2007.
