Resumo
The demands for improved mechanical properties in hot rolled long products are increasing as the expectations of global Standards and construction designer’s increase. Cost constraints limit the excessive use of expensive alloys to meet these expectations. In addition, depending on the mill, equipment can limit what can be realized to meet the increasing expectations. The most effective way to meet the increasing expectations for improved mechanical properties of optimum strength and ductility is through producing steel with as fine as possible uniform cross sectional grain size in the “as-rolled” condition. The best solution to the development of this fine and uniform cross sectional grain size is to develop a cost effective alloy design coupled with proper metallurgical process control implemented into an existing mill’s equipment capability and layout. In other words, properly bringing together alloy, metallurgy, process control and existing equipment capabilities to develop an optimum product that can meet the increasing demands of the construction designer. This paper is designed to give a solid understanding of the production and metallurgical requirements to achieve a grain size in “as-rolled” long products that is as fine as possible within the limitations of the process and production parameters of the individual plant.
