ABSTRACT:
Apparatus for conveying an elongated hot-rolled steel rod in off-set form on a conveyor through a series of cooling chambers. Each chamber comprises a stationary lower section and a removable cover section, the interior walls of each being heat reflective. Each chamber is also provided with tubes supported adjacent the interior walls and controlled in temperature by gas passing through said tubes, said gas being cold or hot, the hot gas being supplied from a plurality of separately controlled burners. The tubes differentially control the rate of heat radiation from the rod rings to compensate for the different rates of radiational heat loss emanating from the top and sides of the rod rings so as to cause the rod to cool uniformly. The side walls of the chamber are provided with adjustable apertures for the escape of radiant energy from the sides of the rod rings. Means are provided for controllably lifting the roof from its completely closed position to one in which the top of the lower section is entirely exposed. Means are also provided for blowing cooling air through the rings. The apparatus provides means for carrying out a process for controlling the loss of heat from the rod by applying radiant heat selectively to the rod, by reflection from the interior walls or by the heated or cooled tubes, or both, substantially in inverse proportion to the accumulated mass of the rod from side to side of the conveyor.
