On-line assembling entirety on-position assembling method of edge mill

Abstract

The invention relates to a method for the integral falling installation of on-line assembly of a vertical miller, belonging to the technical field of installation of large-sale equipment. The installing steps comprise the installation and transverse alignment of the soleplate of the vertical miller, the arrangement of an assembling and falling device, the assembly of an upper beam and a lower beam of a stander outlet, the slippage of a stander torii, the assembly and fixation of an upper beam and a lower beam of a stander inlet; the integral falling installation position of the stander and the installation of a rolling mill transmission device. The invention has the advantages that a special lifting device is not needed to be manufactured; the architecture design of workshops is not needed; the constructing investment is not increased; a field for building a precision assembly platform is not needed to be reserved in a main workshop; the time for the vertical miller equipment to enter the arena is not limited, so the installation cost can be greatly reduced, the labor intensity is lightened, and the time limit for the installation is shortened; and the invention is applied to the projects of installation and repairing of vertical millers attached to hot plate or band roughing mills.

Description

technical field [0001] The invention belongs to the technical field of large-scale equipment installation, and in particular provides an on-line assembly and overall positioning installation method for vertical roller mills, which is suitable for the installation of large-scale hot plate (strip) rough rolling mills attached to vertical roller mills. Background technique [0002] The large-scale hot plate (strip) roughing mill with vertical roll mill is the rolling mill technology imported from Germany Demark-Siemag company. The manufacturing and installation of many sets of equipment that have been put into production in China are all under the responsibility of the foreign technical director. The foreign party's "Installation Manual" stipulates that The installation method of the vertical roll mill frame is as follows: the off-line parts are assembled into a whole, and the "ten"-shaped special hoisting shoulder pole double bridge crane is used to lift and drop it.

AI Technical Summary

Problems solved by technology

[0004] Since the domestically imported hot-rolling production line plant and civil design are generally designed domestically, and the production process equipment is in charge of the foreign technical chief, the owner considers the project cost to reduce costs, and the general plant height and crane arrangement are only for maintenance and maintenance. Equipment installation is not considered, so the height of the plant design is low. In order to ensure the height required for equipment hoisting, many production line equipment is installed by reserving the civil foundation and reserving part of the civil foundation after the equipment hoisting is completed, resulting in civil construction. Interaction with equipment installation is also not conducive to the clean environment requirements required for the installation of steel rolling precision equipment
