The distribution of a magnetic field over an inductor used for sheet castings has been investigated experimentally.With an increase in height from the surface, the magnetic field density decreases according to the exponential law.In the transverse direction, the magnetic field density is approximately uniform except near the edges.The magnetic field density is direct proportional to the number of turns multiplied by the current in amperes.Ferro-magnetic material in the upper mould can enhance the magnetic field density.Under the electromagnetic force, the mould-filling process of sheet casings has been studied by physical simulation method.The difference in filling capability between gravity casting and travelling magnetic field casting has been studied.The electromagnetic force can enhance the filling process, but it also brings a problem.With an increase in the magnetic field density, the surface quality of the aluminum alloy sheet castings becomes poor.The reason is discussed. 展开更多

A two-dimensional heat transfer model was developed to calculate the mould wall temperature field under normal operations condition and to determine its changing behavior when breakout occured. On the numerical simulation of sticking type breakout process and the breakout related wall temperature evolution, parameters of prediction were suggested. 展开更多
