Abstract：

Rotating platform is the most basic metallurgical implement of large-scale hydraulic press, and it is mainly loaded working pressure and high temperature during forging. Taking the designed and developed rotating platform as an object, the stress conditions of rotating platform were analyzed. The compressive stress, thermal stress and deformation of rotating platform for hydraulic press were calculated and analyzed under three different working conditions by using finite element analysis. The calculation result indicates that the maximum equivalent stress value of rotating platform is equal to 192 MPa under the working pressure of 165 MN. Referring to the finite element analysis result, the rotating platform applicable for the work conditions of 165 MN hydraulic press was designed and made by using cast steel ZG270-500, which has safely and stably run for more than 800 hours under working pressure of 165 MN and workpiece temperature of 1200 ℃. The practical application shows that the designed rotating platform can meet the requirements for work, and it is applicable for the working condition of high temperature and heavy load.
