【摘要】：据相关统计,2013年我国具备冷轧硅钢生产能力的企业约有32家,合计产能约为1049万吨而总消费量约为686万吨。从实际产量和硅钢消耗量看,硅钢产能已出现明显过剩。因此在这种市场环境下特别是对于刚刚进入硅钢产品市场3年多的A公司而言,一方面需要通过流程再造、减少浪费、优化资源配置等措施大力降低成本,另一方面则需要通过加强对产品质量的管理,提升产品价值和竞争力、巩固市场地位。本文通过实践案例分析的形式对六西格玛管理方法在A公司的应用进行研究,将生产管理实践和六西格玛理论相结合,分析和解决产品制造过程中的质量管理问题。不仅能够从实际应用角度出发,提升和稳定产品质量、降低质量成本、提高客户满意度;而且从理论研究的角度,通过六西格玛管理理论与质量管理理论相结合,论证了六西格玛管理理论中对质量持续改进的精华方法。文章首先对硅钢卷取温度进行定义,并分析了硅钢生产流程,寻找并验证了关键的影响因子;其次针对每个影响因子制定改进方案加以改善;最后将改进方案固化到控制计划等质量管理文件中。本文不仅从技术上解决了制约卷取温度提升的问题,而且从管理流程角度改进了质量管理流程中存在的问题,从激励角度制定了关键绩效指标和劳动竞赛指标,从素质提升角度分阶段对操作人员进行培训。使得卷取温度合格率长期稳定的保持在较高的水平。
[Abstract]:According to relevant statistics, there are about 32 enterprises with cold-rolled silicon steel production capacity in China in 2013, the total production capacity is about 10.49 million tons and the total consumption is about 6.86 million tons. From the actual output and consumption of silicon steel, silicon steel production capacity has been obvious excess. Therefore, in this market environment, especially for Company A, which has just entered the silicon steel product market for more than three years, on the one hand, it is necessary to reduce the cost by reengineering the process, reducing waste, optimizing the allocation of resources, and so on. On the other hand, we need to strengthen the management of product quality, enhance product value and competitiveness, and consolidate market position. In this paper, the application of six Sigma management method in A company is studied by the form of practical case analysis. The production management practice and six sigma theory are combined to analyze and solve the quality management problems in the process of product manufacturing. Not only can we improve and stabilize the quality of products, reduce the cost of quality, and improve customer satisfaction from the perspective of practical application; And from the perspective of theoretical research, through the combination of six Sigma management theory and quality management theory, this paper demonstrates the essence method of the six Sigma management theory to the continuous improvement of quality. Firstly, the paper defines the coiling temperature of silicon steel, analyzes the production process of silicon steel, and finds out and verifies the key influencing factors. Finally, the improvement program will be solidified into quality management documents such as control plan. This paper not only solves the problem of restricting the rise of coiling temperature technically, but also improves the problems existing in the quality management process from the point of view of management process, and formulates the key performance index and labor competition index from the angle of incentive. Train operators in stages from the point of view of quality improvement. So that the coiling temperature qualified rate of long-term stability to maintain a higher level.
