18.8.2010

SR-Instruments Oy is delivering two Detmaster MPH Pinhole Detection Systems to ArcelorMittal Weirton Works in USA. The systems will be installed in October on Tin Plating Lines No. 4 and No. 6, which line speeds are 550 m/min. Detmaster MPH systems are able to detect pinholes from size 10 um up to large holes, and therefore, they will guarantee the efficiency and the quality assurance at the concerned Tin Plating Lines at ArcelorMittal Weirton Works.


22.4.2010

SR-Instruments Oy is delivering the Detmaster MPH Pinhole Detection System for rental use to the Ternium Mexico's Monterrey mill site in Mexico. The system will be installed on Tension Leveling Line, which maximum line speed is 425 m/min. The Detmaster system is able to detect pinholes from size 10 um up to large holes, and therefore, it will guarantee the efficiency and the quality assurance at the Ternium Mexico's Tension Leveling Line.


7.10.2009

SR-Instruments Oy is delivering the Detmaster MPH Pinhole Detection System to the Impress Deventer Plant in The Netherlands. The system will be installed on Cut-to-length Line No. 102, which maximum line speed is 450 m/min and maximum number of strokes 235 strokes/min. The Detmaster MPH system is able to detect pinholes from 10 um up to large holes and provides a signal to reject the sheets including pinholes. Thus, Detmaster MPH system will guarantee the efficiency and quality assurance at the Impress Deventer Plant's Cut-to-length Line No. 102.

Detmaster MPH - Metal Pinhole Detection System

Detmaster MPH system enables accurate pinhole, hole and edge crack detection as well as an optional width measurement feature.

The primary advantages of the Detmaster MPH system compared to the traditional pinhole gauges are:

  • Measures pinholes from size 10 µm up to large holes with only one measurement system.
  • Is able to detect additionally edge cracks from size 200 µm up
  • Doesn't need any mechanical edge following units and edge masks because it includes active optical edge detection method.
  • Ambient light doesn't interfere to the operation of the Detmaster MPH system because it includes frequency modulated light sources.
  • Includes LED light sources, which have average lifetime of 290 years with constant light intensity.
  • Doesn't include any component, which needs to be changed frequently. It is practically maintenance free system.
  • Informs the position of each pinhole in MD (machine direction) with an accuracy of 1 mm and in CD (cross direction) with an accuracy of 8 mm.
  • Enables categorisation of different size pinholes, holes and edge cracks to own size classes. The operator of the Detmaster MPH system may determine the range for each pinhole, hole and edge crack size class.
  • Provides on a graphical user interface a coil report, which indicates location and size of each individual pinhole, hole and edge crack in a concerned coil.
  • Can be pulled out of the line for verification and maintenance purposes with a roll out system automatically or manually without disturbing running of the process line.
  • Comprises dynamic verification tools for easy system performance verification = motor controlled rotating disc including certified pinhole and hole samples simulating the actual production line speed.
  • Measures optionally the width of the strip with an accuracy of ± 1 mm.
  • Measures accurately pinholes with line speeds up to 2000 m/min.
