A continuous casting furnace includes a temperature control mechanism for controlling the temperature of a metal casting as it exits a continuous casting mold in order to provide improved characteristics of the metal casting. The temperature control mechanism includes a temperature sensor for sensing the temperature of the metal casting, and a heat source and cooling device for respectively heating and cooling the metal casting in light of the temperature of the metal casting. A control unit determines if the temperature of the metal casting is within a predetermined range and controls the heat source and cooling device accordingly. The heat source may double as a cooling device or the cooling device may be separate from the heat source.
