Surface Finish Quantification for Hollow Tube Sections

塔塔钢铁（TS）英国的空心截面业务生产方和矩形管的建筑，起重和挖掘市场。一个关键的'高价值'差异化产品线背后的塔塔的战略，以确保英国钢铁业务，管通常用于应用程序中的外观管是一样重要的管强度。该项目将研究一种能够测量、量化和分类方形和矩形空心型材表面光洁度的系统，该系统能够在恶劣的轧机环境中在线运行。在线测量系统将需要新颖和创新的方法来实现高测量分辨率和吞吐量在TS英国的恶劣的制造环境中，并补偿坑闭塞的残余轧机规模。TS UK和国家物理实验室（NPL）提出了一项方截面管表面检测的可行性研究和技术演示，这是实现管生产过程质量控制的重要第一步。项目的成功预计将为这一关键产品线带来进一步的合作投资，并将其转化为其他应用。该项目将扩大NPL的尺寸表面计量专业知识和解决问题的能力，使其成为英国一个重要的高知名度行业。

Tata Steel (TS) UK's hollow section business manufactures square and rectangular tubes for theconstruction, lifting and excavating markets. A key ‘high-value’ differentiating product line behind Tata’s strategy to secure UK steel operations, tubes are often used for applications where the cosmetic appearance of the tube is as critical as tube strength. This project will investigate a system which is capable of measuring, quantifying and categorising surface finish for square and rectangular hollow sections and which is capable of operating on-line in a hostile mill environment. An online measurement system will require novel and innovative approaches to achieve high measurement resolution and throughput within TS UK’s hostile manufacturing environment, and to compensate for pit occlusion by residual mill scale. TS UK and the National Physical Laboratory (NPL) propose a feasibility study and technology demonstration for surface inspection of square-section tubes, a significant first step towards in-process quality control for tube production. Project success is expected to unlock further collaborative investment for this critical product line, and translation to other applications. This project would expand NPL’s dimensional surface metrology expertise and problem-solving into an important and high profile UK industry.
