The basic theory in the electromagnetic casting and studies on the electromagnetic field

Liquidized metal is bound into shape by the electromagnetic force under the comprehensive action of the complicated 3 - dimensional fields such as electromagnetic field, temperature field, fluidized field, etc. The distribution of electromagnetic field is directly attributed to the success or failure of casting, hence its research is the important basis for the research of casting technology. This paper comprehensively generalizes the basic theory, the main research methods of electromagnetic field, the research contents and current conditions of the electromagnetic casting. It mainly introduces several key and representative achievements in the aforesaid research by utilizing the methods of mathematical simulation . Based on present research conditions, the paper will display the future trends of research development in that field.
