• Slab width - length measurement, with laser sensors :
At the entry or exit of the reheat furnace this system uses a combination of laser sensors to measure critical dimensions of each slab for verification and to optimize the set-up of the rolling mill. Laser sensors measure the width, taper and length of each slab or bloom as it rolls past this measurement station. These measurements are used for protection of the vertical edgers and feed forward set-up of the full mill for optimizing the yield through improved width control.
The system measures tapered and skewed slabs and reports minimum and maximum dimensions and graphic display to help prevent wrecks and cobbles in the roughing mill. This system may be installed at the entry or exit of the reheat furnace or even at the exit of slab - bloom caster.

• Stereoscopic width gauge DigiScan XD4000
The Stereoscopic Width Gauge, designed for installation above the roll tables in hot strip and plate mills and cold rolling mills, is state-of-the-art technology for measuring the width of strip / plate products. For use at the roughing mill or finishing mill exit, the self-emitted optical radiation of the hot strip provides contrast for width determination. An optional backlight mode is available for installation at the entry to the coilers or when the rolling temperatures are below 650°C. For cold mill operation, a high frequency backlight is provided.

Two high speed digital cameras with 4096 pixels each and high-quality multi-lens optics, mounted to a precision optical bed in stereoscopic vision.

• Advanced sub-pixel edge detection software and data capture processor to perform edge localization.
• Compact water cooled sealed die-cast aluminium housing;
• Optional feature includes thermal profile for self emitted gauges.
• Supplied with on-site calibration fixture.
• Ability to monitor the gauge remotely

• Crop optimization system, CropVsion CV3000
Vision System: A high speed array camera is used to capture the images of the head and tail end of the transfer bar. Pattern recognition software intelligently analyzes the image and precisely determines the complete profile of the bar. The optimum cut line is determined by the computer based upon the shape of the bar and the matrix of strategies. Complete color graphic display and operator’s desk panel with trackball controls make this a very readily usable system. An Ethernet connection is provided, as a standard feature, for communication to the host computer. The system incorporates sophisticated diagnostics capabilities on a real time basis. The system has been configured to work with straight through roughing, reversing rougher and coil box operations.

All the sensors have a built in Ethernet TCP/IP connection and the architecture follows the client-server processing model. The sensors capture all the data and compute positions and dimensions. This information along with other I/O and alarm data is passed on to a number of client computers through an Ethernet communication channel.
