Study on Deformation Behavior of Rolled Metal at Ultra High Rolling Speed in Wire Rod Mills


Article Preview

Experiments were carried out by rolling pure iron at ultra high rolling speed. Results showed that the grain size of the rolled products in certain areas is corresponded by the grain size of the matrix. The deformation of rolled metal does not only occur at the surface, but also penetrate to the center when rolling speed is set >100m/s with the corresponded strain rate >2800 S-1. The grain size of the rolled products fits well with the matrix (billet) if distributed evenly. The longitudinal section parallel to rolling direction is analyzed by optical microscope. The grains near the center were stretched in vertical direction, while the ones around the surface were compressed. This is determined by the unique character of groove rolling.
