【摘要】：最大限度满足客户要求是出发点和最终目的,提升服务和盈利水平的途径就是提高质量、降低成本、提高效率的过程。将降低成本、提高质量和设备运转率结合起来研究,追求生产系统的最佳社会和经济效益,是工业工程管理的重要特点。本文针对中铝山东分公司赤泥压滤系统无法满足赤泥堆存要求的实际问题,以确保赤泥堆场安全为前提,以提升赤泥压滤系统效率为目标,运用工业工程管理理论、试验设计方法及质量功能展开工具,分析影响客户满意度的主要因素,制定相应质量措施,得出高重要度的技术指标,提出技术指标提升对策与方案,设计实施试验、方案,并验证了赤泥压滤系统的效率提升。具体内容如下:(1)介绍了客户满意度分析理论、方法,及过滤与压榨理论原理;(2)解析赤泥压滤流程,对赤泥压滤系统客户满意度进行调研,分析影响因素,判别主次因,制定相应质量措施;(3)分析质量措施相对权重,确定技术指标重要程度,分析技术指标提升可行性;(4)提出并实施技术指标提升对策及方案:包括压滤机台时产量和赤泥滤饼水分的正交试验设计实施;对压滤机卸料斗改造,节约非计划性停车时间,提高压滤机的运转率;新增一条循环水输送管路,对渣浆泵冷却水系统进行改造,提高渣浆泵运转率以满足赤泥堆存的要求。上述分析、试验及改造方案的实施提高了中铝山东分公司赤泥压滤系统的生产效率,满足了赤泥堆存的要求,降低了赤泥压滤系统运行成本,公司盈利能力也得到了较大提高。
[Abstract]:It is the starting point and the ultimate goal to meet the customer's requirements to the maximum extent. The way to improve the service and profit level is to improve the quality, reduce the cost and improve the efficiency. It is an important characteristic of industrial engineering management to combine the research of reducing cost, improving quality and running rate of equipment, and pursuing the best social and economic benefits of production system. Aiming at the practical problem that the red mud pressure filtration system of Chinalco Shandong Branch can not meet the requirements of red mud storage, this paper aims at improving the efficiency of the red mud pressure filtration system on the premise of ensuring the safety of the red mud dump, and applies the industrial engineering management theory to the improvement of the efficiency of the red mud pressure filtration system. Test design method and quality function development tool, analyze the main factors affecting customer satisfaction, draw up corresponding quality measures, obtain technical index of high importance, put forward technical index promotion countermeasure and scheme, design and carry out experiment, scheme, design and implement, The efficiency of red mud pressure filtration system is verified. The main contents are as follows: (1) introduce the theory, method, filtration and press theory of customer satisfaction analysis; (2) analyze the process of red mud pressure filtration, investigate the customer satisfaction of red mud pressure filtration system, analyze the influencing factors, distinguish the primary and secondary factors, (3) analyze the relative weight of quality measures, determine the importance of technical indicators, Analyzing the feasibility of technical index upgrading; (4) putting forward and implementing the countermeasures and schemes of technical index upgrading: including the orthogonal experimental design of the time output of filter press and the moisture content of red mud filter cake, the renovation of the discharge hopper of filter press, and the saving of unplanned stop time, The operation rate of filter press is improved, a new circulating water conveying pipeline is added, the cooling water system of slag slurry pump is reformed, and the running rate of slag slurry pump is improved to meet the requirements of red mud storage. According to the above analysis, the implementation of the test and modification scheme has improved the production efficiency of red mud pressure filtration system in Shandong Branch of Chinalco, satisfied the requirements of red mud storage, reduced the operating cost of red mud pressure filtration system, and greatly improved the profitability of the company.
