摘　　要：由于大型模块的尺寸特征，用常规锻造来生产大型模块，不能建立在拔长变形体内避免形成裂纹的机制。对超声探伤报废的三块模块进行解剖试验，表露出的裂纹形貌完全说明了这点。理论分析和生产实践说明了新ＦＭ法是锻制大型模块锻件的最佳工艺技术。Because of size effect of heavy moldlumps, the internal cracks can not be avoided during stretching in conventional forging The fact is fully testified by inspection of cracks revealed in the dissecting tests of three pieces of moldlump scrapped by ultrasonic flaw detection Based on theoretical analysis and production practice, a new FM method has been proved to be the best technology of forging heavy moldlumps
