Dynamic Simulation and Analysis of Rolling Process of Integral Steel Spiral Finned Tube

摘要

Energy efficient integral spiral fin tube is an excellent heat exchanging unit, which is widely applied for the heat exchanging between different gases and liquid medias in heat exchangers. Taking the fin tube production process as the object of study, accurate stress field, strain and temperature fields and dynamic distributions were obtained by gathering rolling process's related parameters, reappearing and forecasting in advance of the rolling process. With the physical rolling process being modeled by three-dimensional dynamic modeling including AutoCAD for model building and Deform-3D for simulation, the thermo-mechanical coupling analysis during rolling was made and the simulation of heat transfer behavior is conducted. The simulation was made for the modification of the teeth shape of the roller, and parameters of fin are improved significantly. The deviations between simulations and test are smaller than 10% except of thickness of fin, which illustrates the results of simulation are agreeable with practical process. The analysis provided fundamental basis for the parameter optimization and design of rolling.
