To obtain a continuous casting material having good rheology and a superior shape retention characteristic in a half-molten state.
This stirring continuous casting equipment 1 is equipped with a spout 15 having a molten metal receiving port 21 faced upward and a molten metal outlet 15 faced downward, a cylindrical water-cooled mold 13 provided just under the spout 15, and a stirrer 23 to give electromagnetic stirring force to the molten metal m in the spout 15. The stirrer 23 has the function to form an upper area A to move the molten metal m in approximately radiating direction a in the spout 15 and a lower area B to turn the molten metal m in circumferential direction b. An upper area forming portion e of the inner circumferential surface d of the spout has a tapered shape whose inside diameter gradually increases toward the lower circumferential edge g from the upper circumferential edge f. Thereby, the molten metal m moving in the approximately radiating direction a and colliding with the upper area forming portion e is moved toward the lower area B, a crystallized product c with high melting point in the molten metal m is spheroidized and gathered to the outer peripheral portion of the continuous casting material, and the shape retaining action of the crystallized product c can thus be utilized.
