USE OF ACCELERATED COOLING DURING THERMOMECHANICAL ROLLING FOR ECONOMICALLY ALLOYED STEEL OF STRENGTH CLASS K60 (X70)

摘要

The requirement is investigated for microalloying steel of strength class K60 with vanadium using thermomechanical rolling technology followed by accelerated cooling from the point of view of changing rolled product microstructure and mechanical properties. The effect of heating on rolled product mechanical properties, performed both using post-deformation accelerated cooling, and without it, is studied.
