Preliminary Study on Temperature Field of a Cylinder Circumferential Surface under Laser Spiral Scanning Quenching

Article Preview

Abstract:

Laser quenching is an important heat treatment process which is used in many industries. It is necessary to ascertain the laser processing parameters before the process is performed. Therefore, a numerical simulation of the temperature field is a good way. This paper reports a numerical model for the temperature rise in the quenched zone of a cylindrical circumferential surface under laser spiral scanning quenching. In this method, the analytical solution is utilized of transient temperature field due to a moving point heat source. This model considers the effect of the adjacent quenched path on the base temperature of quenching performance and assumes a laser beam of a uniform intensity. The surface temperature field was computed based on the method. The analyses also indicate that the temperature at the later cycles area is much higher than that of the first cycles heated area. The practical value of this model will be a help for ascertaining the process parameters of laser spiral scanning quenching on cylindrical circumferential surface for an even temperature distribution.
