Shear Control
Shear control
Our system is a modern cutting control system (SCS) capable of replacing many of the obsolete systems currently installed with a very high degree of backward compatibility.
In most cases, it is possible to reuse all existing digital and analog I/O. When combined with the Vision System software, a significant increase in throughput can be achieved in a very short time. The system can:
- generate views of physical and thermal gradients
- calculate operating parameters such as center deviation, overall width, camber, hook, etc.
Feedback from the cutting control system can be used by the vision system to compare the ideal and optimal cutting point with the actual cutting point, as reported by the cut. These values can be used to calculate the ideal weight of the docked head or tail and the actual weight. All calculations can be organized and viewed in the cut report.
Our optical and vision based solutions represent the state of the art of non-contact width and shape controls on hot and cold strips and slabs but also on long products such as billets and pipes. The dimensional control of width and shape is of particular importance to facilitate subsequent processing by having immediate information on non-conformity and for the purposes of the waste optimizing. In fact, they have always been used online to determine the perfect cutting coordinates and promptly communicate them to the shears and online cutting systems.
The advanced analytic software give access to a wide range of information which may be used for quality optimization purposes. Bar details are presented in the data tables to the right of the images. Typical data displayed includes the Bar ID, Thickness, Optimization Criteria (i.e. customer defined strategy), overall Width, Cut Line Width, Cut Length, Cut Status (to cut or not), Crop Area, Crop Weight, etc. Other parameters can also be displayed based on customer configuration details.
The head and tail images have been colour enhanced to illustrate relative thermal variations over the surfaces. This enhancement is based on correlating camera pixel values to the colour spectrum and we assume a linear relationship between the pixel value and the defined colour spectrum.
- 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
Crop Loss Report
Adopting a crop optimization solution on your process line would consistently reduce / minimize the crop loss. Even the Crop Loss is a necessary loss, which cannot be totally eliminated, hence holding this loss to a minimum level becomes the primary target for the process efficiency. The vision system would lead to a significant increase in Yield through the crop optimization algorithm.
It can be used to create accurate 2-D images of the plate/bar/strip and calculate the most convenient crop option case by case. The system can be used at the exit of the caster for example, or anywhere else on a hot mill, cold mill, or even to a cold process line. Additionally if it is positioned at the exit of a Rougher Mill, the Vision System can captures head and tail images to be used not only for the theoretical crop optimization but also to the actual shear control drive.
