Temperature field Simulation of steel pipe in the induction quenching and tempering process
With the rapid development of Chinas industry on the increasing demand for the steel grade, the performance of the steel pipe has put forward higher requirements. Improving the performance of the steel pipe has two ways: One is increasing the alloying element suitably for the steel pipe and the other is quenching and tempering on the steel pipe. By comparison, the cost and the market competition ability of the steel pipe through quenching and tempering is lower, and the heating mode using the electromagnetic induction heating can save the energy effectively and decrease pollution. The characteristics of steel pipe during the induction quenching and tempering are complex, the change of material properties with temperature makes exact analysis methods very difficult to implement. Therefore, a powerful computer aided numerical tool is selected to numerically model the induction heating process in this paper. The mathematic model coupling with electromagnetic field and thermal field was established, and it was solved by finite element method (FEM), thus the steel pipe temperature distribution and its variation with time were obtained. To validate the model feasible, the results were evaluated and compared with the experiment results, which showed that the simulation results are reliable and effective. At last, the induction quenching and tempering process were studied and demonstrated. The quenching technology and the tempering technology have different temperature requirements, so the two technologies must have different temperature distribution, which caused by different parameters such as the induced power intensity and frequency. These simulation results can provide important information to optimize the whole induction quenching and tempering process.
