Patent ID: 7721786

Claim:
A casting nozzle for supplying molten alloy liquid from a tundish to a movable mold comprising a pair of rolls arranged at mutually opposing positions so as to turn in mutually opposite directions, for continuous casting, the casting nozzle being fixed to the tundish for storing the molten liquid of magnesium alloy or aluminum alloy, wherein the casting nozzle comprises a casting nozzle tip having a multilayer structure including a plurality of layers made of different materials comprising first and second heat-conductive layers each made of a material having a heat conductivity equal to or more than 0.2 W/mK, each selected from iron, nickel, titanium, tungsten, molybdenum and alloys including thereof 50% by mass or more, carbon, and a carbon-carbon composite, wherein the first heat-conductive layer is arranged on an inner circumference of the casting nozzle tip which touches the molten alloy liquid, and the second heat-conductive layer is arranged on a roll side, and wherein at least one layer of a ceramic fiber sheet of low-thermal conductivity is sandwiched between the first and second heat-conductive layers.
