等温锻造工艺的关键是要求坯料在一定温度点或者在一定温度段发生变形,而且对不同变形坯料来说,其最佳变形温度有所不同,所以在等温锻造过程中温度的控制十分重要。锻模的温度要控制在和毛坯加热温度大致相同的范围内,使毛坯在温度基本不变的条件下完成锻造。等温锻造的成形速度很慢,一般在专用设备上进行,且需要特殊的模具加热装置。采用等温锻造加工得到的锻件,组织均匀、机械性能优良,锻件无回弹、尺寸稳定、材料的利用率高、表面质量好。

Isothermal forging process, the key is required billets at a certain temperature point, or deformed in a certain temperature ranges, but also for different deformed billets for the optimum deformation temperature is different, so the process of isothermal forging temperature control is very important. To control the temperature of forging dies and rough heating temperature in the context of roughly the same, so that the temperature will remain basically unchanged rough conditions, the completion of forging. Isothermal Forging of the forming speed is very slow, usually on special equipment, and require special mold heating device. Obtained by isothermal forging of forgings, organizational uniform, excellent mechanical properties, forging no resilience, dimensional stability, high utilization rate of the material surface and good quality.
