Influence of the Normalizing Rolling Parameters on the Toughness of a Nb, V and Ti Microalloyed Steel Processed in the Gerdau Plate Mill

摘要

Normalizing rolling (NR) is a thermomechanical treatment that has been widely applied in recent decades which allows the production of normalized steel heavy plates directly from hot rolling, without the need to perform an additional heat treatment of normalization in the furnace. So, it contributes to speeding up manufacturing and reducing costs.
