description: The theme of the qualifying work: "Modeling the process of anticorrosive surfacing on the inner surface of the steam generator". Purpose of work: optimization of two-layer corrosion-resistant surfacing on the inner surface of the steam generator. Work tasks: 1. Analysis of methods for solving problems of thermal conductivity in welding and surfacing. 2. To develop physical and mathematical models of the process of tapeprecision surfacing on the inner surface of the steam generator. 3. Determine the offset of the start of surfacing of the next pass and the required cooling time. When surfacing on the inner surface of the steam generator, the product gradually warms up. Surfacing of the second layer should only be started if the surface temperature is below 100 Â° C. On the basis of the constructed model, it was established that it is possible to start surfacing the beads of the second layer after 15 - 18 minutes, shifting the beginning by 60 mm in the direction of surfacing. The problem was solved using the analytical method of sources. The model takes into account the distribution of the input energy source over the surface. The body scheme is a cylinder of unlimited length, the surface of which is adiabatic. When surfacing the 1st layer, the thermophysical properties were taken for steel Â«10ÐÐ2ÐÐ¤ÐÂ», when surfacing the 2nd layer, as for high-alloy steel 08Ð¥18Ð10T.
