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.
