The mechanical mixing method is a method for preparing semi-solid alloy used first,electromagnetic stirring method and the control of pouring temperature method is the most with industrial application potential. Many methods of the preparation of semi-solid slurry, besides the mechanical mixing method, and electromagnetic stirring,electromagnetic method
Pulse loading method, ultrasonic vibration mixing method, inclined liquid alloy plate,external force along the curved channel force activities, the strain induced melt activation method, spray deposition, control the temperature of casting alloy.
