Installation method for replacing the guide rail of the sector section of the continuous casting machine

Abstract

The invention relates to a method for installing a replacement guide rail of a continuous casting machine segment, which includes the following steps: Step 1. The upper assembly of the left and right symmetrical two replacement guide rails and the lower section of the multi-piece replacement guide rail are symmetrically placed respectively, and the two symmetrical pieces Replace the upper assembly of the guide rail or replace the lower section of the guide rail as a group, adjust the distance between the two replacement guide rails of each group to meet the design requirements; step 2, use rigid connection between the adjusted two replacement guide rails in each group The rods are connected and fixed; step 3, hoist each group of replacement guide rails connected as a whole to the installation position, adjust the installation position to meet the design requirements, and weld the replacement guide rails on the installation pads of the walls on both sides; step 4, wait for all welding After the seams are connected, the rigid connecting rods are removed. This installation method only needs to measure the data of the replacement guide rail on one side when the fan-shaped segment is replaced with the guide rail, which takes a short time, and at the same time, the welding deformation of the replacement guide rail is small, which improves the installation efficiency and installation quality.

Description

technical field [0001] The invention relates to the technical field of metallurgical equipment installation, and more specifically, relates to a method for installing a guide rail for segment replacement of a continuous casting machine. Background technique [0002] In order to facilitate the maintenance of the continuous casting machine, the sectors of the continuous casting machine are generally equipped with sector replacement guide rails. When the sector is replaced, the sector is hoisted out along the replacement guide rail with a special sling to realize the replacement. At present, most of the metallurgical large-scale continuous casting machines adopt the full guide rail type sector section replacement guide rail, and the full guide rail type sector section replacement guide rail is arranged from the radial direction to the vertical direction when the replacement guide rail is close to the center of the arc. [0003] The installation of the replacement guide rail of ...
