Abstract

In this paper, a simulation model is established to study the temperature rises of the rust layer surface and the metal substrate surface when the continuous laser and nanosecond laser act on the rust layer surface, and draw the temperature charts of the rust layer surface and the metal substrate surface, so as to analyze the temperature rising process of laser cleaning rusty steel plate. The temperature rising process of the rust layer surface and the metal substrate was studied. The simulation results show that: when the continuous laser power is 239W, the peak temperature of the rust layer surface is 1772.1K. At this time, the temperature of the rust layer surface is close to the melting point, but the temperature of the substrate surface has no significant rise. When the power of nanosecond pulse is 5135kW, the peak temperature of the rust layer surface is 1772.8K. At this time, the surface temperature of the rust layer is close to the melting point, but the substrate surface temperature has no significant rise. The results of this paper not only provide a theoretical basis for laser cleaning of rusty steel plate, but also provide a theoretical support for the application of laser cleaning technology.
