PURPOSE: A cold strip rolling mill for preventing a working roll from bending deformation using a magnetic force and a cold strip rolling system including the same are provided to prevent the working roll from bending deformation without a separate vendor facility. CONSTITUTION: A cold strip rolling mill for preventing a working roll from bending deformation using a magnetic force comprises an upper working roll(10), a lower working roll(20), and a magnetic material(30). The upper working roll includes a first milling unit(12) contacting one surface of a strip and a first edge unit(14) extended from both ends of the first milling unit in the lateral direction without contacting the strip. The lower working roll includes a second milling unit(22) contacting the other surface of the strip and a second edge unit(24) extended from both ends of the second milling unit in the lateral direction without contacting the strip. The magnetic material adds the magnetic force to generate a repulsive force between the first edge unit and the second edge unit. |
