For example, the deployment of Lut 2.0 has facilitated the online real-time measurement of wall thickness in hot seamless tubes and pipes, by utilizing the non-contact feature of laser-ultrasonic technology.<\/p>\n<p>The broad ultrasonic bandwidth inherent to laser-ultrasonics allows for detailed frequency analysis, enabling advancements such as real-time grain size measurement. Previously, such measurements were confined to controlled laboratory settings, typically involving a thermo-mechanical simulator. However, a team led by Mr. Mikael Malmstr\u00f6m at SWERIM has recently developed and operated an online grain size gauge using laser-ultrasonic technology for hot steel coils.<\/p>\n<p>In collaboration with EMG Automation, a prototype unit has been successfully installed at SSAB in Borl\u00e4nge, Sweden. The team&#8217;s comprehensive research, published in the journal Applied Science, describes the methodology employed to extract grain size data from laser-ultrasonic attenuation measurements.<\/p>\n<p>The outcomes of their study effectively demonstrate the ability of laser-ultrasonic technology to provide real-time insights into the mechanical properties of produced steel coils. This breakthrough opens up new possibilities for steel producers to enhance control over the quality characteristics of their products.<\/p>\n<p><a href=\"https:\/\/www.mdpi.com\/2076-3417\/12\/19\/10048\" target=\"_blank\" rel=\"noopener\">Link to paper<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>For several decades, laser-ultrasonic technology has been employed in industry to obtain dimensional information about hot steel products.
