Advance integrated installing method of converter

Abstract

The invention relates to a converter installing method. The installing method comprise the following steps that: an in-front converter feeding plant-crossing crane beam system is installed; cleaning is carried out on the in-front converter feeding crossing field; the field is levelled and compacted and a temporary track is laid; two buggy ladles are lifted on the temporary track and are connected by a section steel and a steel plate is laid so as to form an integrated mobile platform; a converter installation rack is installed on the integrated mobile platform; a backing ring that is completed by external assembling is lifted at the converter installation rack; an integrated converter housing that with completed external assembling is lifted in the backing ring and the buggy ladle integrated platform is pulled to a converter foundation design position; the converter and the backing ring are declined to a reduction box pedestal by an integrated way; the subsequent installation work of the converter is completed within three to four weeks; and after a converter trolley reaches a designed position, the temporary track is removed immediately and the converter equipment installation and high-layer frame steel structure installation are carried out synchronously and alternately. According to the invention, the processes can be carried out in advance for converter installation.

Description

technical field [0001] The present invention relates to a converter, and more particularly to a converter installation method. Background technique [0002] Usually, the installation of the converter can only be carried out after the steelmaking span is closed and the ladle car track foundation construction is completed. [0003] As we all know, the closure of the cross-factory building for feeding needs to first complete the installation of the third column of the high-rise frame, the lateral movement of the oxygen lance and the operating platform, the oxygen valve station, the nitrogen valve station platform, the half-span roof structure of the high-rise frame, the wall skin system, the vertical air shaft, etc. , and the construction of the ladle car track foundation within the range of the feeding span needs to wait until the large crane used for steel structure installation exits the area before it can start. After the construction of the track foundation is completed, ...

AI Technical Summary

Problems solved by technology

The track foundation of the slag-packed car within the span of the converter is completed with the overall construction of the converter foundation. Formally, this method seems to save the construction and maintenance time of the track foundation after the large crane for cross-area hoisting is withdrawn, but it is seriously delayed. It shortens the start time of the installation of high-rise frame steel structures, and at the same time brings great hidden dangers to the protection of finished products, and also increases the cost of protection measures or repairs of finished products

[0005] In recent years, the construction period requirements of steelmaking projects have become shorter and shorter. These two common methods are also unfavorable to the organization of the entire construction period and cannot meet the construction needs.
