A method for in-plant assembly of an ultra-heavy large-size rolling mill stand

Abstract

A method for assembling an ultra-heavy, large-size rolling mill stand in a factory, relating to the field of heavy machinery assembly technology, is disclosed. The rolling mill stand includes two rail supports, two frames, and an upper crossbeam. The assembly method includes the following steps: S1, Site preparation: Based on the external dimensions and weight of the rolling mill stand, an assembly site with sufficient lifting and assembly capabilities is selected; S2, Constructing an assembly foundation platform: A modular support foundation is constructed at the foundation of the assembly site, formed by layering individual supports. This assembly method enables flexible, modular construction of the assembly foundation platform across regions, improves the overall rigidity of the modular assembly foundation, enhances the assembly accuracy of the rolling mill stand, and solves the problem of difficulty in adjusting the ultra-heavy mill stand into position after installing the upper crossbeam in traditional rolling mill stand assembly processes. This results in a rolling mill stand assembly process characterized by flexible layout and high rigidity.
