【Abstract】 The steel tube hot rolling reducing-sizing process is simulated by means of a large-scale and nonlinear finite-element analysis software Marc. Some problems in the simulation and their solvents are dissertated, especially the establishment and simplification of the model, the definition of the boundary condition, the parameters design of the temperature field, the definition of contact and so on, which could provide reference for dealing with the same problems.更多还原
