摘要:本文针对酒钢六座炼钢转炉的机械特性、钢结构和工艺要求,结合生产实际,对转炉活动段烟道更换方法进行了深入分析和阐述。分别介绍了酒钢炼钢一工序三座转炉和酒钢炼钢二工序三座转炉的机械结构,对转炉的几段烟道也做了分析。对转炉烟道更换的难度、技术要求、方案制定、施工步骤和施工后的效果做了综合分析。对于活动段烟道的更换,自酒钢建厂以来进行了几百次,这其中方法更是多种多样,一直以来也没有进行过统一,这在一定程度了浪费了很多的检修资源,也降低了酒钢的冶炼成本,本着检修成本最小化,经济效益最大化的要求,对最近一次转炉活动段烟道更换方法做了一个综合分析,以便在日后的检修工作中参照实施,缩减检修成本。
Abstract: In this paper, six JISCO mechanical properties of BOF steelmaking, steel structure and process requirements, combined with the production of the actual activities of the converter flue above methods to replace an in-depth analysis and on. JISCO introduced three steel-making process of a steelmaking converter and the second process JISCO three of the mechanical structure of converter, the converter flue of paragraphs are also analyzed. Replacement of the converter flue the difficulty of the technical requirements,programming, construction steps and after the construction has done prehensive analysis of the effect. For the replacement of the flue above activities, since the plant JISCO hundreds of times since, which is a variety of methods has been carried out since there is no unity, which to some extent a waste of a lot of maintenance resources JISCO smelting reducing costs, maintenance costs based on minimizing the requirements to maximize the economic benefits of the activities of the last paragraph of converter flue replacement method has made prehensive analysis, in order to work in the future in the light of the implementation of maintenance, reduced maintenance cost.

引言:对于转炉活动段烟道更换方法探讨这一题目来源于酒钢07年炼钢二工序1#转炉大修。当时酒钢检修工程公司刚刚成立,公司本着检修成本最小化,检修经验最大化的思路,对08年后进行的大的检修工程进行方法的探索,以便积攒经验,探讨检修系统的改革。对于转炉活动段烟道更换方法近些年没有进行过专门的探讨,公司在这上面吃过几次亏,每次到检修前,大家忙的焦头烂额,每次制定的方案都差异很大,检修成本一再追高,本课题就是要解决这一困扰公司多年的检修难题,通过对几年前的多个检修施工方案,进行比较、归纳,结合最近的一次检修案例,制定了这一最贴切生产实际又能缩减检修工期和成本的新方法。此方案已经过实践验证,是切实可行的,前期预料的问题基本上与实际相符,在实施过程中,对实际施工中投入的人力、机具、施工作业的时间段、交叉作业的实际情况、质量的保证情况进行了实际记录,施工结束后也进行归纳总结,根据实际情况对方案进行修改,修改后的方案作为检修作业标准实施,为今后更换奠定了理论基础。通过对炼钢转炉一段烟道更换工艺的改进,控制
