| Laser Measurement: 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: 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 700°C. For
cold mill operation, a high frequency backlight is provided.

| Crop Shear Optimization System: 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. Control System: The Control System ensures that the shear cuts the transfer bar exactly at the optimum cut line. A four-axis motion controller measuring the speed of the transfer bar near the shear does this. The Vision System transmits the cut line information to the Control System controller. The Control System calculates the correct time to trigger the shear based on the speed and position of the transfer bar and known acceleration characteristics of the shear. |

Measurement
System for Hot Strip Mill: All
the sensors have a built in Ethernet 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. |

Operators
interface - Client Workstation:
•
Networked system with Client Server architecture: the core information
is available on the network and maybe displayed in different formats at
different workstations at the same time.
