连铸坯低倍检验系统建设实践

Construction practice of low magnification inspection system for continuous casting billets

为充分发挥低倍检验在连铸坯质量控制中的作用,对低倍检验各个工序进行了研究,重新设计了符合管理体系要求的低倍实验室。制定了自动低倍检验工艺流程,对试样加工及转运、酸蚀工艺、扫描成像工艺、环保工艺等低倍检验工艺进行了设计,对低倍实验室建设中涉及的工艺总体布局、土建、材质等方面以及实验室管理方面提出建议,为钢铁企业物理检验质量管理人员和低倍实验室设计建设人员提供了参考。

In order to fully play the role of low magnification inspection in quality control of continuous casting billets,each process of low magnification inspection was studied.A low magnification laboratory that met the requirements of the management system was redesigned.The automatic low magnification inspection process was formulated.The low magnification inspection processes were designed,including the sample processing and transportation,acid etching process,scanning imaging process,and environmental protection process.The suggestions for the overall layout of the process,civil engineering,materials,and laboratory management involved in the construction of the low magnification laboratory were proposed,which provided reference for the physical inspection quality management personnel and low magnification laboratory design and construction personnel in steel enterprises.
