Calibration of a portable coercivity measurement instrument for assessing low-carbon steel

我们公司位于曼彻斯特，专门开发电磁无损检测(NDT)产品。在过去的几年里，我们成功地开发了一种新型的矫直力仪，它具有便携性、测量速度快以及对样品制备的最低或零要求--这是现场无损应用的独特优势。该系统已经商业化，向客户发布，并在现场部署。我们在不同行业发现了不同的应用程序，并一直在不断增加我们的技术体验和客户参与度。例如，客户的反馈证实，使用我们的新产品后，热处理评估的效率有了很大的提高。过去需要5到6名工程师和20分钟的流程现在减少到2名工程师和2分钟。其他应用包括钢结构和电缆的老化和疲劳检测、残余应力分布和成品测试。与NPL一起，设计了一种实验测量装置，为MAIERIC的参考样品创建可追溯链。NPL将比较MAIERIC参考标准和标准几何形状确定的矫直磁力值。软磁材料的直流磁性通常使用磁导法(在BSI/IEC 60404-4中概述)来确定。目前的测量标准通常仅限于定义良好的几何图形。作为直接比较，NPL将修改现有的设置以适应MAIERIC较小的非标准几何形状。我们的目标行业包括电力、交通和开发、海洋、航空航天、冶金、化工和采矿，主要应用于评估使用寿命、钢结构、关键部件、机械等的老化和疲劳、成品质量、金属分类，广义上是对钢的整个使用寿命进行评估。能够为每个应用程序生产可追溯的测量结果意味着我们可以快速扩大我们的市场。我们相信，解决我们目前的校准和可追溯性问题将为MAIERIC带来可观的额外收入。除了增加销售收入外，还可以提高我们和客户的流程效率，以节省成本--从而实现显著的财务收益，并为曼彻斯特社区的技术和创新生态系统做出贡献。

Our company, located in Manchester, specialises in developing electromagnetic non-destructive testing (NDT) products. In the last couple of years, we have successfully developed a novel coercivity meter, which features portability, fast measurement speed and minimal or null requirements for sample preparation - unique advantages for on-site non-destructive applications. The system has been commercialised, released to clients, and deployed in the field. We have found diverse applications across different industries and have been continuously growing our technical experience and customer engagement. As an example, client's feedback confirms large efficiency improvement on heat-treatment assessment after using our novel product. A process that used to require 5 to 6 staff engineers and 20 minutes is now reduced to 2 engineers and 2 minutes. Other applications include aging and fatigue detection of steel structures and cables, residual stress distribution and testing of finished products.Together with NPL, an experimental measurement setup has been devised to create a traceability chain for MAIERIC's reference samples. NPL will compare coercivity values determined on MAIERIC's reference standards to those determined on standard geometries. The DC magnetic properties of soft magnetic materials are typically determined using the permeameter method (outlined in BSI/IEC 60404-4). Current measurement standards are generally limited to well defined geometry. For a direct comparison NPL will modify and existing set-up to accommodate MAIERIC's smaller, non-standard geometries.Our target industries include power, traffic and developments, marine, aerospace, metallurgy, chemical and mining, with main applications on assessing working life, aging and fatigue of steel structures, critical components, machinery, etc., quality of finished products, metal sorting, in a wide sense, assessment of steel during all its service life. To be able to produce traceable measurements for each application means we can expand our market quickly. We are confident that solving our current issues of calibration and traceability will bring to MAIERIC substantial additional revenue. As well as increasing sales revenue, improve process efficiency for both us and clients to save costs -- hence realising significant financial gains and contributing to the technology and innovation ecosystem of the Manchester community.
