| Abstract: | Rotary electromagnetic stirring has been applied in continuous casting steel, molding and solidifying of casting, making of semi-solid size, purifying of liquid metal, to which people who engage in materials field have attached importance. Fruits in both technology development and theoretical study have been gotten. This article analyzed the characteristics of liquid metal fluid flow affected by rotary electromagnetic stirring and the calculation of electromagnetic force. A mathematical model about liquid metal affected by rotary electromagnetic stirring was set up, and expressions of velocity were given. The effect of rotary electromagnetic stirring on solidification structure in continuous casting billet was studied. These offer reference for the optimization of processing parameters when using rotary electromagnetic stirrer. |
