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 …

Precise Looper Position Feedback

Loopers are normally used to control the tension of the metal strip between roll stands. The rotational angle of the looper is measured by a feedback encoder that is exposed to special demands. For this application Johannes Hübner Giessen developed a special looper encoder, which boasts a considerably longer lifetime thanks to especially designed-in features. …
