Pyromters Prevent Strip Cobble Due to Hook Up
Measure the bottom/ under-strip temperature. Measure the bottom profile temperature to prevent hook-up / cobble. Technology now available for both point and profile bottom side temperature measurement. Compare the edge temperature difference between operator and drive side Home Case Studies Prevent strip cobble due to hook-up Pyromters Prevent Strip Cobble Due to Hook Up Home …
Overspeed switch EGSH 41 ensures safely limited speed in the mill stand
For precise speed control in rolling mills the main drives of the roll stands and the coilers need to be equipped with an encoder. In addition, it is often necessary to provide increased protection for personnel during special operating modes, such as: For this application Johannes Hübner Giessen has been working with Motor OEMs for …

Slab Detection in Excessive Steam (HMD)
On the roughing mill exit, there is a lot of steam due to the spray header. The steam obstructs field of view of the traditional scanning type HMDs as result, occasionally the signal flickers for a millisecond. The next generation HMD 4.0 from Proxitron have intelligent software features which allows to set dual thresholds (hysteresis). …
Temperature Measurement at Roughing Mill entry and under the strip
Hot rolling mill processes needed accurate temperature measurement, as well as efficiency in extremely high temperature. Rugged pyrometer was installed at the measuring site, with electrically isolated sensing head and fiber optic.
