PURPOSE: An apparatus for cooling hot forgings is provided to improve fatigue strength by cooling the forgings passing through hot forging process with air sucking and blowing units as transferring the forgings through a conveyor, thereby micronizing final crystal grains of the forgings. CONSTITUTION: The apparatus for cooling hot forgings comprises a housing(10) having a plurality of chambers(11) divided into compartments; a conveyor system traversing each of the chambers(11) to transfer materials to be processed; blowers(30) and exhaust fans(40) which are mounted on lower and upper parts of the chambers(11) respectively; and a controller(50) controlling the conveyor system, blowers(30) and exhaust fans(40).
