COOLING SYSTEM FOR THICK PLATE OR STEEL PLATE

摘要

PURPOSE: A cooling system for a thick plate or a steel plate is provided to minimize staying water by forming a swirl pattern to enhance momentum resulting from the flow of cooling water. CONSTITUTION: A cooling system for a thick plate or a steel plate comprises a transfer unit which transfers thick plates or steel plates, a nozzle unit(120) which is arranged above the transfer unit and spraying cooling water supplied through a plurality of flow paths(123) through spray holes(122), and a control unit which controls the jet speed of cooling water. Six spray holes are arranged at regular intervals of angle around one spray hole to form a spray module. A spiral swirl pattern(124) is formed in different directions on adjacent inner walls of the spray module.
