Steering rolls with proportional integral steering guide – Type SRH

The function of the SRH steering roll is to feed the strip material centrally into the strip looper. Following travel over a longer free inlet zone, major strip errors may be corrected on a 90° deflector roll equipped with this guidance system, making use of the advantages of the winding effect. For the outlet section, twice the maximum strip width is sufficient. In the case of long free inlet and outlet sections, the system can also be used together with a 180° deflector roll.

The swivel frame with the assembled deflector roll is guided via two steering levers so that a suitable combination of the angle formation between the strip and roll axis (I-portion) and a lateral displacement of the strip (P-portion) is achieved. In addition to the exact outlet position of the strip, a centring effect is also achieved in the inlet zone. The maintenance-free Inductive strip centre measuring system type SMI is installed immediately downstream of the steering roll here to detect the strip position.
