A device for removing an annular oxide film that is generated when a cylindrical metal material is heat-treated in the air, and that is a device that abrades the oxide film by contacting the metal material. a support member that receives the liquid absorbent member and constitutes at least a portion of one electrode body, and the other electrode body that contacts the surface of the metal material, and uses an external power source to connect both electrodes. A predetermined potential is applied between the bodies to generate a locally high current density, and the liquid absorbent member is impregnated with the acid treatment liquid, and the liquid absorbent member or metal material is relatively rotated to produce the liquid absorbent member. A cyclic oxide film removal device that separates oxide films one by one. 2. The apparatus according to claim 1, wherein the support member is a receiving plate with an arc-shaped side surface, and the used dilute acid treatment liquid discharged from the receiving plate is circulated to the tank by a pump. 3. The apparatus according to claim 1, wherein the support member is a cylindrical roller, and the fresh dilute acid treatment solution is forcibly fed to the roller by a pump.
