The luffing mechanism of the 6# stacker-reclaimer (DQ3000/4200) of an iron-making plant has malfunctions in production. After analyzing the fault reason of the original pitching mechanism. We optimize the hydraulic mechanism for solving these problems, and established a 3D model for the optimization part. The original hydraulic system and the improved hydraulic system model were established under AMEsim. The purpose of this study was to compare the movement speed of the hydraulic cylinder piston under different set pressures of the pressure valve to verify the improved hydraulic system meets production needs.
