The SIROLL^CIS Crop Optim System minimises the amount of wasted material by typically 0.3% to 0.4% of the annual rolled tonnage, resulting in large savings and a fast pay back.

The SIROLL^CIS Crop Optim system, utilises a combination of stereo and single cameras between the exit of the roughing mill stand and the entry to the crop shear. The stereo camera determines the position of the edges and, together with the single lens position camera looking down web, is able to accurately determine the contour and hence shape of the head and tail sections.

This arrangement can be positioned at the entry to the crop shear to evaluate the shape, optimise the crop position, track the head or tail and control the shear. Alternatively the two cameras can be positioned at the exit of the last roughing stand and an additional single lens camera is positioned at the entry to the crop shear. This arrangement has the benefit of providing both crop position evaluation and width measurement well upstream of the crop shear. This allows operators to visualise the optimised crop positions before the slab reaches the shear. In both cases speed and position are very accurately tracked right up to the shear, which permits the system to compensate for any variations in speed shortly before the crop.

A range of additional signals from other sensors before/after the shear can also be processed to provide a back up system.
