PURPOSE: To facilitate an automatic control and to obtain a copper mold having good shape little in bending by specifying the difference between molten metal temp. and an anode surface temp., casting the molten metal and specifying the anode surface temp. at the time of completing the spraying of cooling water.
CONSTITUTION: Plural molds 2 are placed on a turn table 1 and the casting, cooling and detachment are executed while rotating the turn table 1. In this anode casting, the difference between the molten metal temp. at the time of casting and the anode surface temp. at the first position pushing up the shoulder part side of the anode in the mold 2 upward, is made to be ≤300°C, to eliminate the bending and the twisting of the shoulder part of the anode. Further, a control valve 9 in a cooling water spraying piping 8a is adjusted so that the anode surface temp. at the time of completing the water spraying for executing the cooling of the anode and the mold 2 becomes ≤650°C. By this method, the temp. in the anode is dropped so lower degree as not to develop the buckling.
