摘要
论述了消除锻件内部裂纹的措施,一是采取热修复既自修复机制,二是在大型锻件锻造生产过程中,采用宽砧走扁方压实先进工艺和收孔工艺方法。通过实验和大量生产实践证明,上述方法是提高大型轴类锻件、饼类锻件、厚壁筒类锻件内部质量的重要途径。
It＇s expounded measures of eliminatingforglng internal cracks. First adopt the hot repair the selfrepair mechanism. Second, use the advanced technique of compaction law of hammered into flat square through wide block and eliminating holes in the large-scaie forging production process. It is proved through the experiment and the mass production practice that the above methods are the important way of improving internal quality of the large-scale axis-shaped forging cake-shaped forging and thick wall tube forging.
