The utility model relates to the technical field of cranes, and provides a special lifting hook for a metallurgical crane in a steel mill, which comprises a pulley yoke, pulleys rotatably mounted at two ends of the inner side of the pulley yoke, steel ropes wound on the two pulleys, a connecting shaft rotatably mounted at the bottom of the pulley yoke, and a hook fixedly mounted at the bottom of the connecting shaft. A limiting piece is arranged on the inner side of the pulley yoke and comprises a mounting seat, sliding rods are fixedly mounted at the two ends of the bottom of the mounting seat, the two sliding rods penetrate through the bottom wall of the pulley yoke and are in sliding connection with the pulley yoke, and a limiting roller is rotationally mounted on the inner side of the mounting seat and makes contact with a steel rope on the pulley. When the steel rope is lifted, the limiting roller can guide the steel rope and rotate the steel rope, so that rolling friction exists between the limiting rol
