ABSTRACT:
A continuous casting apparatus, continuous casting method and aluminum alloy cast bar enable stable and smooth high-speed casting with a reduced amount of a lubricant and prevent occurrence of breakout and lubricant reaction products, resulting in reduction in ingot failure. The present invention provides a continuous casting apparatus for producing aluminum alloy cast bars, including a tundish containing molten aluminum alloy, a mold which has an upstream end and a downstream end and to which the molten aluminum alloy is supplied through the upstream end of the mold, an insulation member which is disposed between the tundish and the upstream end of the mold and which has a molten metal passage for allowing communication between the tundish and the mold, and a separation layer disposed on the insulation member and having an aperture which is in communication with the molten metal passage, wherein a lubricant which has been supplied to the mold and transferred to the insulation members is blocked with the separation layer.
