六西格玛方法在不锈钢表面质量改进中的应用
|
摘要
不锈钢表面质量是不锈钢性能及使用过程中的关键指标,近年来,随着不锈钢使用领域进一步拓宽,对不锈钢表面的要求越来越高,不锈钢表面已由过去的简单要求发展到现在的镜面、拉丝、磨砂等复杂工艺要求。而在生产实践中,不锈钢的表面却难以实现较大突破,不锈钢表面质量一直是制约不锈钢整体质量的关键因素。
本文旨在通过六西格玛方法来尝试解决不锈钢表面质量问题。首先通过对我厂不锈钢表面质量的现状进行了分析,并与国际先进企业进行对比,找出存在差距,运用六西格玛方法的理论进行问题研究,寻求解决方案。
本文共分四章,第一章将不锈钢生产流程及表面质量现状及对企业发展影响提出了论述,第二章主要简单介绍了六西格玛的起源及一些理论上的方法及步骤,第三章运用六西格玛的方法实际解决我厂不锈钢表面质量问题,通过DMAIC的流程对问题进行研究。最后一章是质量控制与效果分析。
通过本文的研究,用六西格玛方法解决质量问题的思路清晰,虽不能完成解决如不锈钢表面质量这类高难度的课题,但可以用六西格玛的科学方法对问题进行分析,能避免不必要的弯路,对一个课题是管理问题还是技术问题可以很好地界定。
Stainless steel surface quality is a key parameter of stainless steel performance during use process. In recent years usage field of stainless steel has developed a lot, the requirement for stainless grows higher and higher. Simple requirement for stainless steel already changed to complicated technical requirements, such as mirror surface, drawbench, dull polish. But during production, it is very difficult to get improvement in stainless steel surface field; surface quality of stainless steel is a key point restricting stainless steel whole quality system.
This paper tries to solve stainless steel quality using six sigma method. First we made the analysis for current stainless steel quality on our steel making plant, and we also made comparition with world level advanced enterprises, finally we found the difference among us, and we used six sigma method to reseach problem and find solution.
This paper is divided into 4 chapters, first chapter discoursed upon stainless steel production route and recent surface quality, quality influence for enterprise also is involed in this chapter. Second chapter explained about origin of six sigma method and six sigma theoritics and steps. Third chapter explained how to solve stainless steel surface quality problem using six sigma methon and how to research problem with DMAIC flow sheet on our steelmaking plant. Last chapter is for quality control and effect investigation.
Through this text thinking way of using six sigma to solve quality problems is very clear, though we can not solve stainless steel surface quality problems at all, but we made the investigation using six sigma method, avoiding unnecessasary wrong works, this method can define project is a management problem or a technician problem.
