As a widely used equipment in continuous casting process, the installation process of ladle rotary table is complicated and requires many installation equipment. According to the practical engineering application, this paper takes the installation device as the research object, and optimizes the original structure of the installation device. SolidWorks software was used to model the overall structure of the installation device, and the established model was imported into Hypermesh for mesh division, and finally into ANSYS for finite element analysis to compare the stress and deformation of the structure before and after optimization.The results show that the stress of the optimized structure is reduced to some extent, and the practical application requirements are met.

In the process of hoisting the memorial archway, because the balance beam directly lifts the memorial archway, it is easy to deform during the hoisting process, and the deformation will affect the follow-up work, resulting in the delay of the project progress. In order to avoid this situation, the existing conditions are used to calculate the load that the balance beam can bear. Using 3D modeling and numerical simulation software, conduct force analysis on the balanced beam, and compare the simulation results with the calculated values to determine whether the stress and deformation of the balanced beam meet the requirements. The simulation results show that the stress on the balance beam during the lifting process does not exceed the maximum yield stress of its own material, which meets the requirements of the working conditions.
