When every micrometre counts:
With the VTLG Series laser gauges, Vollmer is once again setting new standards:
They are the only gauges worldwide that operate in the cold rolling mill and also serve for automatic gauge control (AGC). As with our tactile systems, they measure the thickness irrespective of the alloy.
The contact strip thickness gauges that measure the thickness of the strip with a precision in the micrometer range are renowned for their exceptional reliability. Over a thousand contact strip thickness gauges bear evidence to the worldwide success of the Vollmer contact gauges. They still form part of the initial equipment of new mills even today.
Our X-ray and isotope strip thickness gauges are characterised by their very lean design. With a minimum overall width of 120 mm, our C-frame gauges have room in even the most confined of spaces.
The automatic thickness control closes the process loop: Using the results of the thickness measurement, we control the mill screwdown so that the desired tolerance can be reliably achieved in the process: From simple position control through mass flow control right up to the unique and high-speed direct roll gap control.
