【摘要】：近年来,耐火材料行业的主要下游行业如钢铁、建材及有色金属等,受经济下行趋势影响明显,致使耐火材料企业订单量锐减,销售额骤降。同时,大多数耐火材料企业仍然依靠低价格获得市场份额,使得行业内竞争愈演愈烈。如何通过提升产品质量、降低成本来增加客户满意度与市场份额已成为耐火材料企业迫切需要解决的现实问题。R公司是耐火材料行业的领军企业,但其大连工厂生产的RH浸渍管产品却屡屡收到客户抱怨。本文以R公司大连工厂为对象,为解决客户投诉反馈问题,针对工厂RH浸渍管生产线存在的实际问题,利用六西格玛方法改善产品质量,优化生产管理,提高过程能力进行了系统的剖析,提出并验证了改进方案。首先,本文介绍了研究的背景,行业与企业的发展现状以及R公司大连工厂RH浸渍管生产线所面临的问题。其次,综合论述了质量管理与六西格玛方法等相关理论的发展与应用。然后,对目前RH浸渍管生产线生产管理与质量管理的现状进行了阐述,指出其中不足之处及在大连工厂运用六西格玛方法的必要性。对此,为最终提高客户满意度,本研究使用DMAIC过程,转化客户需求,将客户需求与生产管理联系起来；寻找重点影响因素,得出尺寸精加工工序对产品性能影响最大；确定主要改进目标,在精加工阶段实施统计过程控制等；实施改进计划,验证初步效果,阐述对公司管理水平的影响。研究表明,六西格玛方法在R公司大连工厂浸渍管生产线上可以得到很好的应用,符合工厂实际,可以有效地提升产品质量与管理水平,对于最终提高客户满意度、增强市场竞争力及扩大市场份额都具有积极意义。同时,六西格玛方法对于其他耐火材料企业同样具有借鉴意义。
[Abstract]:In recent years, the main downstream industries of the refractory industry, such as steel, building materials and non-ferrous metals, are obviously affected by the downward trend of the economy, resulting in a sharp decline in orders and sales of refractory enterprises. At the same time, most refractory enterprises still rely on low prices to gain market share, which makes competition in the industry intensified. How to improve product quality and reduce cost to increase customer satisfaction and market share has become an urgent need to solve the real problem of refractory enterprises. But the RH dipping pipe produced by its Dalian factory has repeatedly received complaints from customers. In order to solve the problem of customer complaints and feedback, this paper takes R Company Dalian factory as an example to improve the product quality and optimize the production management by using six Sigma method to solve the problems existing in the production line of RH impregnated pipe in the factory. The improvement of process ability is analyzed systematically, and the improvement scheme is put forward and verified. Firstly, this paper introduces the background of the research, the development of industry and enterprise, and the problems of R company Dalian factory RH impregnated pipe production line. Secondly, the development and application of quality management and six Sigma methods are discussed. Then, the present situation of production management and quality management of RH impregnated pipe production line is expounded, and the inadequacies and the necessity of applying six Sigma method in Dalian factory are pointed out. In order to improve customer satisfaction, this study uses DMAIC process to transform customer demand, connect customer demand with production management, find key influencing factors, and draw the conclusion that dimensional finishing process has the greatest impact on product performance. To determine the main improvement objectives, to implement statistical process control in the finishing stage, to implement improvement plan, to verify the preliminary effect, and to elaborate the influence on the management level of the company. The research shows that the six Sigma method can be applied to the impregnated pipe production line of Dalian factory of R Company, which is in line with the actual situation of the factory, and can effectively improve the quality and management level of the product, and finally improve the customer satisfaction. Enhancing market competitiveness and expanding market share are of positive significance. At the same time, six Sigma method is also useful for other refractory enterprises.
