压裂泵阀箱因其使用工况特殊，不仅各向力学性能要求很高，且要求横向性能与纵向性能尽可能接近；然而，阀箱锻件为矩形截面轴类锻件，在锻造生产过程中由于金属纤维流线的存在，难以保证锻件的横向性能与纵向性能一致。针对锻件异向性的影响因素，对此类锻件的成形特点和锻造工艺现状进行了分析；以控制锻件金属流线为核心思路，对现有锻造成形工艺进行了优化，采用合锻换向和三向镦粗拔长的工艺改善了锻件异向性。为进一步提升阀箱锻件各向性能和同批次锻件性能的均匀性，结合空心类锻件成形特点和性能优势，创新性地提出将矩形截面轴类锻件转换为环圈锻件来锻造成形的工艺技术。通过实际生产，验证了该工艺技术的有效性和先进性。

For the special working conditions of valve box for fracturing pump, not only the mechanical properties in all directions are very high, but also the transverse and longitudinal properties are required to be as close as possible. However, the valve box forgings are shaft forgings with a rectangular section, and it is difficult to ensure that the transverse performance is consistent with the longitudinal performance, because of the metal fiber streamlines generated during the forging process. Therefore, for the influencing factors of the anisotropy of forgings, the forming characteristics and forging process status of such forgings were analyzed. Based on the idea of controlling the metal streamline of forgings，the existing forging process was optimized，and the anisotropy of forgings was improved by using the technology of merging forging to change the direction of forgings and the technology of upsetting and drawing from three directions. In order to further improve the anisotropy performance of valve box forgings and the performance uniformity of the same batch forgings, combined with the forming characteristics and performance advantages of hollow forgings, the forging technology of transforming rectangular cross-section shaft forgings into ring forgings was innovatively proposed, and the effectiveness and advancement of the process technology were verified by actual production.
