【摘要】：近年来,钢铁行业已经由世界的重要支柱产业逐步转变成微利行业,大部分钢铁企业甚至出现了不同程度的亏损。各钢企都在寻求突破点,向管理要效益,努力降低成本、增加利润。随着市场对平整钢卷的需求增多,QG公司热轧1#平整机组实际生产量低的问题日益突显,无法接单、客户流失,影响了公司的经济效益和品牌形象,也影响了公司的长远发展。六西格玛管理法诞生于美国的摩托罗拉公司,成长于通用电气。经过近30年的发展壮大,已经成为比较成熟的管理方法和手段,被世界各国、各行各业的人们所接受并应用于实践。我国对六西格玛管理法的研究和应用比国外起步晚,但发展较快,方兴未艾。QG公司自2007年召开六西格玛管理启动会以来,已成功开展了多个六西格玛项目,取得了良好的经济效益和社会效益。但项目多以提高产品质量、提高产品合格率为主,涉及整条生产线生产过程优化的,还是空白。本文以六西格玛管理法为理论基础,以QG公司推行六西格玛管理为实际支撑,以QG公司热轧1#平整机组为研究对象,从1#平整机组的生产现状入手,分析目前生产过程存在的问题及问题成因,提出运用六西格玛DMAIC模式对1#平整机组生产过程进行优化的整体思路和实施方案。通过本文的研究,为QG公司热轧1#平整机组生产过程的优化提供思路,从而达到提高产量、满足客户要求、提高企业经济效益和企业竞争力的目的。并以此拓宽QG公司六西格玛项目的选择实施范围,帮助公司更好地推行六西格玛管理。同时,也希望对QG公司其他类似生产线、国内其他钢铁企业类似问题的解决提供一定的借鉴作用。
[Abstract]:In recent years, the iron and steel industry has gradually changed from an important pillar industry in the world to a small profit industry. Most steel enterprises have even suffered losses to varying degrees. With the increasing demand for flat steel coils in the market, the problem of low actual production of hot-rolled 1# leveling units in QG Company has become increasingly prominent, resulting in the loss of customers due to the inability to receive orders. Six Sigma management method was born in the United States Motorola, grew up in General Electric. After nearly 30 years of development and growth. It has become a more mature management method and means, accepted and applied to practice by people in various industries and countries all over the world. The research and application of six Sigma management in our country started later than that in foreign countries, but the development is relatively fast. Since 2007, when the six Sigma Management Start-up meeting was held, the company has successfully carried out several six Sigma projects. Good economic and social benefits have been achieved, but the projects are mainly to improve the quality of products and improve the qualified rate of products, involving the optimization of the production process of the whole production line. This paper is based on six Sigma management method, taking the implementation of six sigma management in QG company as the practical support, and taking the hot rolling mill of QG company as the research object. Starting with the present production situation of the 1# leveling unit, the problems existing in the production process and the causes of the problems are analyzed. This paper puts forward the overall idea and implementation scheme of optimizing the production process of the 1# leveling unit by using the six Sigma DMAIC model. Through the research of this paper. To provide ideas for the optimization of the production process of the hot rolling 1# leveling unit in QG Company, so as to increase the output and meet the requirements of the customers. The purpose of improving the economic efficiency and competitiveness of enterprises is to widen the scope of implementation of the six Sigma Project in QG Company and to help the company to carry out the six Sigma management better. At the same time. It also hopes to provide some reference for other similar production lines of QG Company and similar problems in other domestic steel enterprises.
