The present invention relates to a replacement-type cylindrical electromagnetic pinning coil and a pinning coil replacement-type electromagnetic pinning apparatus using the same, wherein the replacement-type cylindrical electromagnetic pinning coil is a metal plate having a center hole for each diameter of a cylindrical electromagnetic pinning material, wherein the center hole A working coil in which an insulating portion cut from the outer circumferential surface is formed, and wire fixing portions are formed on both sides of the insulating portion; Consisting of a closed-loop casing for fixing the working coil therein by forming a recess into which the outer circumferential surface of the working coil is inserted, it is characterized in that the working coil can be replaced according to the diameter of the electromagnetic pinning material. . According to the present invention, the weight of the pinning coil is reduced so that the entire pinning coil can be formed of copper, the device movement or replacement of the pinning coil is easy, and when the diameter of the workpiece is changed, the entire pinning coil needs to be reprocessed. There is an advantage of providing a cylindrical electromagnetic pinning coil of a replacement method and an electromagnetic pinning device using the pinning coil, which solves the problem of the coil design, material order, and time from reprocessing to stocking according to the re-processing and re-processing.
