An air cooling apron equipment of a continuous casting apparatus is provided to improve productivity by efficiently designing an apron used in the continuous casting, thereby substantially reducing an area required between rolling parts for the rolling process in continuous casting and reducing the production process time. In an apron used in a continuous casting apparatus, an air cooling apron equipment of the continuous casting apparatus comprises: a nozzle member which is installed at one side of the apron, and has a plurality of air nozzles to eject cold air through the air nozzles; at least one cold air supply line connected to the nozzle member to supply cold air to the nozzle member; a vortex tube(30) of which a cold air outlet is connected to the cold air supply line, and which separates cold and hot airs from the compressed air and exhausts the cold and hot airs by receiving compressed air and rotating the compressed air; an air compressor connected to the vortex tube to supply compressed air into the vortex tube; and a hot air exhaust line connected to a hot air outlet of the vortex tube to exhaust hot air to the outside, wherein cooling air generated from the vortex tube cools hot worked steel ingot of continuous casting. The vortex tube comprises a cylindrical body part(31), a compressed air inlet(32), a vortex generating part(33), a cold/hot air separating part(34), an air flow control plate(35), a cold air induction plate(36), an air amount control part(37), a hot air outlet(38), and a cold air outlet(39).
