PURPOSE: To continuously and stably produce semi-solidified metal having a prescribed solid phase ratio at a prescribed discharging velocity.
CONSTITUTION: This method is the one, which supplies molten metal between a rotor 1 for stirring having large heat conducting capacity and composed of horizontal axis cylindrical barrel and a fixed wall 4 and continuously and stably discharges the semi-solidified metal 16 from a discharging port 11 at the lower part. A gap interval between the fixed wall 4 at the part approached to the discharging port 11 and the rotor 1 for stirring is adjusted according to the viscosity of the semi-solidified metal decided by cooling velocity, shearing strain velocity and the solid phase ratio of the semi-solidified metal.
