In this study, the distribution of electromagnetic pressure and the coupling between shaping force and temperature field are investigated in electromagnetic contactless shaping process for plates of stainless steel and superalloy. The distributions of electromagnetic pressure on outlines of melt cross sections are very different along sides than at corners. Under the vacuum, the cooling ability is not strong enough, and therefore the position of melt in inductor is too low, which causes an unbalance between electromagnetic pressure and static pressure. Experiments show the insert of a screen shell from the bottom of inductor can change the distribution of magnetic field very much and make a good and stable coupling between shaping force and temperature field.
