2D Oberflächeninspektion: Oberflächenfehler selbst unter härtesten Umgebungsbedingungen sicher erkennen

The non-contact detection systems of IMS Messsysteme GmbH have formed an integral part of process lines in rolling mills since the 1980s, contributing significantly to quality control and assurance in the manufacture of flawless and documented end products.

The wide-ranging IMS product portfolio therefore also includes high-precision systems for virtually every measuring task in hot and cold aluminium rolling mills, such as measurement of thickness, thickness profile, width, wedge, coating and flatness. Placed at strategic points in the production process, all IMS measuring systems work while the process is running and deliver essential data for precise plant control through the integrated quality management and evaluation system.

One exception to this was – until today – the surcon 2D surface inspection system, which is already firmly ensconced in the production and processing of steel.

Seit dem Entwicklungsstart im Jahr 2008 profitieren mittlerweile weltweit namhafte produzierende Unternehmen von Brammen, Grobblechen, komplexen Profilen – wie Doppel-T-Trägern oder Spundwänden – sowie nahtlosen Rohren von den hochperformanten surcon 2D und 3D Oberflächeninspektionssystemen.

Since development began in 2008, well-known manufacturers of slabs, heavy plates, complex profiles such as double-T beams or sheet piling as well as seamless tubes have benefited from the high-performance surcon 2D and 3D surface inspection systems.

The logical consequence of the experience gained from these very successful reference projects for IMS could therefore only be to develop the already well-established surface inspection systems further for detection of highly reflective materials.

The more advanced a production process is, the finer both the surfaces and the defects become. For this reason, it does not suffice for reliable detection of surface defects occurring there to detect only with the help of a bright field area, as is the case with matt surfaces.

2D Oberflächeninspektion für Aluminiumwalzwerke

Surface defects that produce light reflections are not visible in the bright field. The solution to this problem is an additional camera beam placed in the dark field area, which reliably detects, visualises and documents even the smallest defects.

A real milestone in this direction was the successful adaptation of the existing system configuration for inspection of shiny steel and hot-dip galvanised surfaces. For IMS, this simultaneously sounded the kick-off for taking the final step towards engineering a surface inspection system for aluminium.

In 2017, initial laboratory tests and evaluations of aluminium samples already yielded extremely promising results, quickly leading to active field tests in 2019. However, various challenges specific to the aluminium industry still had to be overcome before the surcon 2D surface inspection system for aluminium was finally ready for series production.

The harsh environmental conditions and confined spaces in aluminium rolling mills also place increased demands on the mechanics of the measuring frames.

The aggressive kerosene-based rolling oils used in the production of aluminium strip are particularly problematical here. Special modifications therefore had to be developed to protect the sensitive equipment of the surface inspection systems safely over their complete life cycle.

Further, to ensure a flawless inspection result, it is essential to keep the camera and illumination windows free of oil deposits at all times, and the seals of the housing must also be able to withstand the corrosive environment.

In addition, the confined space conditions in rolling mills require a very individually adaptable design of the inspection system. Working in close cooperation with engineering teams on site, surcon’s system designers succeeded in constructing a flexibly adaptable system that also grants easy access for maintenance work.

In the end, the verification of previous test results as well as additional on-site evaluations led to today’s optimally designed set-up of the surcon 2D surface inspection system for continuous detection over the complete range of aluminium strip.

The advantages for customers in the aluminium industry for continuous process optimisation are clear:
