Study On The Technology Of The 120t Converter System Replacement

Since twenty-first Century, the development of the international steel industry is facing more and more severe challenges, the prices of the steel are declining, steel plants has entered the era of low profit.How to achieve the maximum efficiency in the case of low profit, has become the hot issues of iron and steel enterprise.In recent years,domestic steel converter system common equipment maintenance costs high, equipment replacement frequency and maintenance cycle is too long, which not only caused a serious economic loss, but also has the adverse effect to the stability of the enterprise.Therefore, in the converter system maintenance and repair process, it is necessary to each system of converter replacement technology in-depth study, so as to ensure the best equipment status, and shorten the maintenance period of converter system.This article mainly decomposite the work structure of the 120 t converter demolition and erection,detailed to every step. On the basis of work decomposite structure, we analysis each process, find the best installation technology, analysis of the main points of construction technology, summary countermeasure, combining the construction period and quality, meet the best requirements, in order to achieve maximum profits.The main purpose of the research is to guide the demolition and erection of the converter system with the theory and method of the comprehensive use of the system,includes:(1) study on the replacement technology of converter bulk system(2) technology of converter flue system replacement(3) study on the technology of the replacement of the converter gas purificationand disposal system(4) study on the replacement of other auxiliary equipment of converterThrough a large number of converter system replacement project practical experience, this article synthetically use of relevant theories and methods of effective guidance of converter system replacement, comprehensively improve the level of construction technology, greatly shorten the construction period, contribute to the steel enterprises to maximize profits.
