Abstract
A liquefied carbonated gas abyssal casting apparatus prevents freezing at an outlet of a casting tube and flotation of cast carbonated gas. The liquefied carbonated gas is fed from a reservoir to a single casting tube and discharged to the abyss through an inner tube of a double casting tube from a lower end of the single casting tube. A heat medium fluid is recirculated between the inner tube and an outer tube of the double casting tube. The liquefied carbonated gas which flows through the inner tube is heated to an abyssal temperature of from -1.degree. to 5.degree. C.
