PURPOSE: Multi-rolling equipment with auxiliary cooling units is provided to reduce the time in which an individual roller table is in contact with the thick plates by increasing a moving section for repeated air-cooling of the thick plates, thereby preventing the roller table and a roller table motor from overloading. CONSTITUTION: Multi-rolling equipment with auxiliary cooling units comprises a rolling unit(100), thick plate transfer units(200,200'), auxiliary cooling units(300,300'), and a control unit. Air-cooling areas are formed on both sides of the rolling unit and roll thick plates(10) transferred from the outside. The thick plate transfer units are arranged on both sides of the rolling unit to be exposed to the air-cooling areas and transfer the thick plates. The auxiliary cooling units are arranged near the thick plate transfer units and selectively draw out the transferred thick plates to be air-cooled. The control unit transfers the thick plates to the thick plate transfer units and the auxiliary cooling units and air-cools the thick plates for a predetermined time.
