FEM analysis of partial flash processing for a plate

FEM analysis of Partial Flash Processing (PFP) was carried out by ANSYS to simulate the heat treatment of wear-resistant steel plate. PFP involves rapid induction heating and water cooling to get different properties of a plate in thickness direction. The steel plate which moves at a given velocity is heated by a stationary inductor and then cooled by spraying water. The temperature filed and the difference of microstructure and properties of the plate in PFP were studied. The electromagnetic and thermal coupled problem will be solved by sequentially coupled physics analysis. The nonlinearities of both the electromagnetic and thermal material properties are also taken into account. Cooling condition will be loaded as a function of water spray position on the surface of steel plate. The FEM analysis results are compared with the measure data, and they are in good accordance. The microstructure and the depth of hardening layer prove the FEM analysis results are credible. The relationship between the tempera...
