Companhia Siderúrgica Paulista - COSIPA, Brazil
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:
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.
