Abstract

as the customers demand new, more resistant and dimensionally challenging (thinner and/or wider) steel grades, actions have been carried to improve thickness performance and reduction of internal losses while still meeting the more restrict tolerances booked by the customers. This paper presents the recent evolution of thickness performance, the reduction of internal losses and the main actions deployed.
