Abstract:
1. A method of manufacturing a cast alloy of aluminum alloy or magnesium alloy, the method comprising the steps of: supplying molten alloy liquid from a tundish to a movable mold comprising a pair of rolls by using a casting nozzle, the casting nozzle being fixed to the tundish for storing the molten liquid of aluminum alloy or magnesium alloy; and continuously casting, by using the casting nozzle, a cast alloy of aluminum alloy or magnesium alloy, wherein the casting nozzle comprises a casting nozzle tip, the casting nozzle tip comprises a first layer, a second layer and a third layer, each of the first layer and the second layer is each a heat-conductive layer made of a material having a heat conductivity equal to or more than 0.2 W/mK, and the second layer is arranged on an inner circumference of the casting nozzle tip which touches the molten liquid, and the first layer is arranged on the movable mold side, and wherein the third layer is sandwiched between the first layer and the second layer.
