Abstract

Abstract

The property improvement of the semi-steel roll surface after laser quenching was investigated experimentally, and the effect of technological parameters on laser quenching was analyzed. The thermal circulating procedure of the surface under the laser beam was elaborated by numerical simulation methods and the principle of laser quenching on the surface is explained consequently. The distribution of thermal gradient near the laser spot was obtained, and the reason for crack formation during laser beam scanning was discussed.
