【摘要】：目前,钢铁工业已经成为一个微利行业,但钢铁工业的竞争却日益激烈。钢铁工业的快速发展离不开铁矿石烧结造块技术的有力支撑。降低成本,改进技术,开发、抢占新市场成为各大钢铁公司在竞争中取胜的主要战略。很多企业希望借助精益六西格玛管理方法来提高烧结矿质量、降低生产成本。本文结合M钢铁企业精益六西格玛管理的现状,运用DMAIC模型及其工具,详细阐述六西格玛管理的五个阶段——项目界定、测量、分析、改进和控制在烧结生产中的应用,并对改进效果进行系统分析与总结,提出具体可操作的措施。首先分析M企业实施精益六西格玛的必要性与可行性;然后根据顾客需求确定烧结改进项目,并在分析测量系统的可靠性的基础上,结合因果矩阵分析确定关键改进因子;最后通过DOE方法确定最佳原料配比,用主成分分析法和聚类分析法确定最优操作参数,并在控制阶段制定各操作标准。本研究以M企业第一炼铁总厂为平台,在对精益六西格玛管理理论和烧结生产流程进行全面理解的基础上,将该理论直接应用于烧结过程的质量控制中。通过精益六西格玛方法在炼铁厂烧结生产实践中的应用,提升了企业质量管理水平,降低了生产成本,产品质量也得到很大改善,更大限度地增强了企业的核心竞争力,同时对员工全心全意投入到工作中也起到了很好的激励作用。另外,本研究可为精益六西格玛管理在其他相关企业的推进提供一定的借鉴与指导作用。
[Abstract]:At present, the iron and steel industry has become a small profit industry, but the iron and steel industry increasingly fierce competition.The rapid development of iron and steel industry can not be separated from the strong support of iron ore sintering technology.Reducing costs, improving technology, developing and seizing new markets are the main strategies for major steel companies to win in the competition.Many enterprises hope to use Lean six Sigma management method to improve sinter quality and reduce production costs.Combined with the present situation of Lean six Sigma management in M iron and steel enterprises, the application of DMAIC model and its tools in the five stages of six Sigma management, including project definition, measurement, analysis, improvement and control in sintering production, is described in detail.The improvement effect is systematically analyzed and summarized, and practical measures are put forward.Firstly, the necessity and feasibility of implementing Lean six Sigma in M enterprise are analyzed, then the sintering improvement project is determined according to the customer demand, and the key improvement factors are determined based on the reliability analysis of measurement system and causality matrix analysis.Finally, the optimal raw material ratio was determined by DOE method, the optimal operating parameters were determined by principal component analysis and cluster analysis, and the operation standards were established in the control stage.On the platform of No. 1 ironmaking plant in M enterprise, the theory is directly applied to the quality control of sintering process on the basis of a comprehensive understanding of Lean six Sigma management theory and sintering production process.Through the application of Lean six Sigma method in sintering production practice in ironmaking plant, the enterprise quality management level has been raised, the production cost has been reduced, the product quality has also been greatly improved, and the core competitiveness of the enterprise has been enhanced to a greater extent.At the same time, it also plays a good role in encouraging employees to devote themselves to their work.In addition, this study can provide some reference and guidance for Lean six Sigma management in other related enterprises.
