The objective of this work was to increase the metallic yield of the plate rolling process through the achievement of a more rectangular shape of the rolling stock extremities. This can be done through the modification of the thickness profile of the rolling stock in the last pass of the broadsizing step, simulating a "dog bone" shape.

The steps of this development were:

1. Simulation of System Operation (Sept. 1990 to Jan. 1991)
2. Automation of the 4100 Plate Mill Screw and Link with the Mainframe Computer (Jan. 1991 to April 1991)
3. Industrial Trials (April 1991 to Aug. 1991)
4. Industrial Implementation (since Sept. 1991)

This development allowed a increase of 0,7% in the metallic yield of the plate rolling process, that is, an economy of 227 tons of steel per month.
