Service centers and cutting lines

In cutting lines such as slitting shears and cut-to-length shears, final quality control of the material to be supplied is an advantage. In addition to deciding whether the cut sheet or cut ring meets the requirements, the measuring systems from Micro-Epsilon also allow complete documentation and logging of the production. For measurements in front of the knife, the powerful software enables the evaluation and documentation of the individual strips.

One of the advantages of the C- and O-frame measuring systems of the thicknessCONTROL MTS 8201/8202 series becomes particularly clear in this area. The high lateral resolution of discrete laser lines enables both thickness measurements as well as width and cambering detection.

Thanks to Micro-Epsilon's broad sensor portfolio, the thickness measuring systems can be customized for further measurement tasks or to compensate for influences on the mechanics due to temperature or mounting tolerances.

•  Patented compensation of angular errors of the sensor system to the material
•  Measurement of cambering with integrated optical micrometers
•  Material widths up to 1000 mm with C-frame and 3000 mm with O-frame
•  Independent of surface, material and alloy
•  Synchronized calibration for all measured variables in seconds

3D profile measurement of long products

Long products such as profiles, billets, etc., which are produced by rolling, drawing or forging, often have complex cross-sectional geometries. DimensionCONTROL measuring systems are used for geometrical inspection of long products. Depending on the application, these can be equipped with ThruBeam sensors, red and blue laser profile scanners to provide the optimal solution for the application. The systems operate with impressive precision even under the toughest hot rolling conditions. Integrated, fully automatic calibration compensates for the temperature-related, potential long-term drift of the mechanical structure.

The dimensionCONTROL MPG 8208 and MPG 9208 systems are designed as horseshoe frames and generate real 3D data with which the target values are calculated.

•  Can be equipped with ThruBeam sensors, red or blue laser line profile sensors
•  Pneumatic protection of sensor optics, optional water cooling
•  Flexible interface for communication with production

Heavy plates

With their large thicknesses, the products produced in heavy plate mills, which are used for example in bridges, pipelines or oil rigs, represent a challenge for isotope and X-ray equipment in terms of measurement technology and costs.

The thicknessCONTROL systems are equipped with special sensor technology and can precisely measure sheets and slabs with a thickness of more than 400 mm in both hot and cold states. Potential applications for the equipment are behind quarto stands for mill control or quality control, since the thickness is no longer changed downstream. Usually, reversing stands are used at this point, where a single C-frame measuring system detects the center thickness. If the plate is stopped for the change of direction, the width and thickness profile can also be measured.

The thicknessCONTROL 8202 and 9202 systems are also used in shearing lines for final quality assurance.

For large widths (> 1000 mm), the C-frames of the thicknessCONTROL MTS 9202/ 8202 series are made of steel to ensure the required precision. This makes them ideal for use in wide heavy plate applications.

•  Available with blue or red laser line for red-hot glowing or non-glowing material
•  Precise detection of the edge due to the high lateral resolution of the laser line enables width measurement
•  Easy integration of non-contact length measurement
•  Operation of multiple measuring systems from one human-machine interface

Cold mills / Processing lines

Thickness measurement for control and quality inspection is at many positions and so is an important element in the process landscape of cold rolling mills. Common places of application for systems for detecting the center thickness or the cross-profile are strip entry or exit of pickling lines with tandem mills, reversing mills as well as finishing lines.

Based on confocal sensor technology or laser line triangulation, Micro-Epsilon offers high-precision thickness measuring systems with the thicknessCONTROL MTS 8201/8202 series, which operate with high precision in the submicrometer range.

In processing lines, such as for tinning, hot-dip galvanizing or painting, thickness measuring systems are used at many points to ensure that the high demands on the product as well as on efficiency are met. Due to the wide portfolio of sensor technologies with which the thicknessCONTROL systems are available, high precision can be achieved for a wide variety of surfaces. For further measurement tasks in the area of process lines, Micro-Epsilon offers infrared temperature sensors and displacement sensors.
