SCS Shear Control
Installing a Shear Control System in a Hot Strip Mill is to reduce/manage the Crop Loss.
Crop Loss is a necessary loss in any Hot Strip Mill which cannot be eliminated, hence holding this loss to a minimum level becomes the primary objective.
Our system is a modern PLC-based Shear Control System (SCS) with sharp performances and extremely high reliability, that can optimize the crop loss since the first use.
Due to its architecture flexibility, it can replace many obsolete systems with very few adjustments.
In most cases, all of the existing digital and analog I/O can be reused.
When combined with Vision System Software, a significant increase in Yield can be achieved in a very short time.
With SCS you'll be able to:
- Generate views of physical and thermal gradients
- Calculate operational parameters such as deviation from center, overall width, camber, hook, etc.
- Raise an alarm in case of excessive conditions, such as excessive hook
- Calculate operational parameters such as deviation from center, overall width, camber, hook, etc.
Feedback from the Shear Control System can be used by the Vision System to compare the ideal, optimum cut point with the actual cut point as reported by the Shear.
These values can be used to calculate the ideal weight of the Cropped Head or Tail and the actual weight. All of the calculations can be organized and displayed on Crop Loss Report.
- Technology:Artificial Vision
- Measurement:Hot slab / plate shape and thermal map
- Architecture:PLC based + PC as HMI
- Software:Dynamic sub-pixel interpolation
The sole purpose and objective of installing a Crop Optimization and Shear Control System in a Hot Strip Mill is to reduce/manage the Crop Loss. Crop Loss is a necessary loss in any Hot Strip Mill which cannot be eliminated, hence holding this loss to a minimum level becomes the primary objective.
SCS system is based on the Stereoscopic Width Gauge is a precision measurement device used to determine the width of sheet or strip products during rolling. This unit is a vision-based, noncontact measurement system, capable of providing real-time width measurements with typical accuracy of within +/- 0.5 mm of the true width. The Width Gauge determines width by imaging the edges of the strip within the focal depth of the system. The stereoscopic design feature allows for accurate width measurement even if the strip is moving up or down within the measurement area.
