镁合金挤压阳极生产过程控制

Production Process Control of Extrusion Magnesium Sacrificial Anode

镁合金挤压阳极是主要应用于家用电热水器和热水锅炉、输油和输汽管道等结构的阴极保护产品,特别是由于电热水器等家用特殊用途的需要,使得镁合金挤压阳极的内在质量控制变得非常严格,同时对于镁合金挤压阳极的更换也带来不便,这就对阳极的种类、重量和质量提出更高的要求。本文旨在利用过程控制的方法通过对镁合金挤压阳极的坯料材质净化控制、镁合金挤压阳极成型控制、镁合金挤压阳极的组装控制等生产过程的质量控制研究有效地解决镁合金挤压阳极生产过程中的质量问题,达到规模化生产的水平。在本文中对用户关心的成本与安全问题也进行了简要描述。通过TPM系统的推行和价值工程的应用,使镁合金挤压阳极的化学成分、微观组织,使用性能、成本以及安全指标达到了或超过了有关标准的要求。

Extrusion magnesium sacrificial anode(EMSA) is cathode protective production applied to domestic electric water heater,boiler,gas and oil transmission pipelines,etc.Because of the special using purpose of domestic electric water heater,it needs a serious control of inherent quality of EMSA and it is very inconvenient to replace them,so there are higher requests for their category, weight and quality than that of tradition.In this research,methods of production process control(PPC) were applied to control of purification of raw material,molding and assembly of EMSA to solve effectively the control of quality of EMSA and achieve the sweeping production standard.Problems of cost and safety which customers care were also introduced simply.Relation standards of chemical component,microstructure,application performance,cost and safety parameters of EMSA are achieved or exceeded by using of total production maintenance(TPM) and value project.
