Abstract

According to the characteristics of electromagnetic induction heating

the coil can be heated quickly without contacting with the material.Based on the above mentioned features

a method on how to rapidly heat the cylindrical core of aluminum alloy housings for electric vehicle was put forward to preheating temperature by electromagnetic induction coil.This method can enhance the filling fluidity of the low pressure casting aluminum alloy

and prevent defects such as shrinkage cavities in the solidification process.The heating parameters and turns of induction coil were determined by calculation

and the finite element temperature field analysis was carried out to analyze the process of the electromagnetic heating core by using ANSYS software

so as to provide accurate technological parameters for temperature control and induction heating and technical basis for selecting reasonable heating process for low pressure casting core.
