A casting method according to the present invention includes: a process for drawing a cast piece from the mold, and tracking the head position of the cast piece in real time while moving the cast piece along a strand comprising a plurality of zones arranged so as to be aligned in a certain direction; and a process for performing a secondary cooling of the cast piece by spraying cooling water into each of the plurality of zones, wherein the process for performing the secondary cooling of the cast piece includes a process for spraying a main spraying amount of the cooling water into the current zone in which the cast piece head is currently positioned among the plurality of zones. Therefore, according to an embodiment of the present invention, the cast piece, while passing through each of the plurality of zones of the strand, is cooled to the required target temperature in each zone, and thus supercooling or delayed solidification of the cast piece can be prevented or inhibited.
