【摘要】：六西格玛是一种能够严格和高效地改善企业流程管理质量的实施原则和技术,实质就是要在努力提供完美的、高水平服务的同时,努力降低企业的不良质量成本。随着六西格玛管理在戴尔、摩托罗拉等众多跨国企业的成功应用,它已经从单纯的一个流程优化概念,衍生成为一种管理哲学思想。它不仅仅是一个衡量业务流程能力的标准,不仅仅是一套业务流程不断优化的方法,进而成为一种应对动态的竞争环境,提升企业竞争力,取得长期成功的企业战略。混匀矿是烧结生产的重要原料之一。自2009年首钢京唐公司投产以来,混匀矿质量取得了质的飞跃,为稳定烧结矿质量做了很大贡献。2013年下半年至2014年,公司经营策略要求最大限度的消纳含铁固体废弃物。固废由于其成分不稳定的特性对混匀矿质量造成了很大的负面影响,已经影响了烧结生产。提高混匀矿质量的呼声日益提高。本文运用六西格玛管理方法,分析、解决混匀矿生产过程存在的问题,主要内容包括:调研混匀矿的生产过程及产品质量指标,收集TFe稳定性数据,并对质量控制方法进行分析,明确存在的问题。系统研究六西格玛管理的作用和内容,确定选择六西格玛管理方法作为质量改进方法,并制定具体的工作计划。然后按照六西格玛管理实施步骤(定义、测量、分析、改进、控制)研究分析混匀矿生产存在的质量问题,提出改善建议并实施。最后对六西格玛管理实施效果进行评价,探讨六西格玛管理方法在首钢京唐公司推广的前景。六西格玛管理的应用不仅提高了混匀矿TFe稳定性,同时促进了原料管理水平的全面提升,也为公司进一步推行六西格玛管理方法提供了经验积累。
[Abstract]:Six Sigma is a kind of implementation principle and technology that can improve the quality of enterprise process management strictly and efficiently. In essence, it is to try hard to provide perfect, high level service and reduce the bad quality cost of the enterprise at the same time. With the successful application of six Sigma management in Dell, Motorola and other multinational enterprises, it has evolved from a simple concept of process optimization into a philosophy of management. It is not only a standard to measure the ability of business process, but also a set of methods to optimize business process, and then become a strategy to deal with the dynamic competition environment, enhance the competitiveness of enterprises, and achieve long-term success. Blending ore is one of the important raw materials for sintering production. Since Shougang Jingtang Company put into production in 2009, the quality of mixed ore has made a qualitative leap, which has made a great contribution to stabilizing the quality of sinter. From the second half of 2013 to 2014, the company's business strategy requires the maximum consumption of solid waste containing iron. Because of its unstable composition, solid waste has a great negative effect on the quality of mixed ore and has affected the sintering production. The voice of improving the quality of mixed ore is increasing day by day. In this paper, the six Sigma management method is used to analyze and solve the problems existing in the process of blending ore production. The main contents include: investigating the production process and product quality index of blending ore, collecting TFE stability data, The quality control method is analyzed and the existing problems are clarified. The function and content of six Sigma management are systematically studied, and the six Sigma management method is chosen as the quality improvement method, and the concrete work plan is worked out. Then according to the six Sigma management implementation steps (definition, measurement, analysis, improvement, control) research and analysis of the mixed ore production quality problems, put forward suggestions for improvement and implementation. Finally, the effect of six Sigma management is evaluated, and the prospect of applying six Sigma management method in Shougang Jingtang Company is discussed. The application of six Sigma management not only improves the TFE stability of blending ore, but also promotes the overall improvement of raw material management level, and also provides experience accumulation for the further implementation of six Sigma management method in the company.
