The Vision System can be used to create important, accurate 2-D images of the bar/strip. The system
can be used at the exit of the caster, or anywhere on a hot mill, cold mill, or process line. At the exit of a
Rougher, the Vision System can capture Head and Tail Images to be used for Crop Optimization and/or
Shear Control. In addition, the Vision System can be configured to capture the image of the entire top
or bottom surface to:
generate views of physical and thermal gradients
calculate operational parameters such as deviation from center, overall width, camber, hook, etc.
alarm in case of excessive conditions, such as excessive hook
The Vision System can be used to image the Head or Tail of the bar/strip while it is rolling
down the line. The System uses a state-of-the-art line scan camera to image the width of the
roller table. In the case of a hot bar/strip, the natural radiance of the bar/strip is adequate for
imaging. Single lines can be stacked to produce a detailed images. Automatic exposure
control in the software results in a very clear image that can be further processed in real-time,
or archived for review/analysis at a later date.
Hot slab / plate shape and thermal map
Generate views of physical and thermal gradients
Calculate operational parameters such as deviation from center, overall width, camber, hook, etc.
Software, with dynamic Sub-pixel interpolation.
The Vision System can be further enhanced to generate a complete 2-D
image of the top or bottom of the bar/strip. The pixel intensity can be correlated to a pyrometer input to result in a complete thermal map of the bar/strip. A high-resolution image can be saved to the database for
The efficient solution for the thermal and defect analysis
