During the rolling process in hot strip rolling mills may occur irregularly shaped head and tail of the slab. This may cause problems when rolled. Crop optimization is the process by which an ideal length of material is trimmed off the head and tail end of each plate due to an accurate and fast width measuring

Crop optimization systems by OPTOLOGIC capture precise geometric contours of head and tail of the slab and determine the optimum cut lines.

Advantages:

• Determination of the optimal cut line as well as irregularly shaped head and tail ends of the plate (ski or fishtail)
• Minimization of crop losses
• Precise measurement by the use of high-resolution line scan cameras
• Remote maintenance possible
• Warning in case of positive or negative ski via digital output
• Graphical display of optimum cut line and contour of head and tail of the plate
