ABSTRACT:
A conveyor has successive mutually spaced driven rollers in which hot rolled steel rod is transported in the form of overlapping offset rings. The rings are rapidly air cooled by first nozzles which direct first jets of cooling air upwardly to impinge against and to flow around the conveyor rollers, and by second nozzles which direct second jets of cooling air upwardly between the rollers. The first and and second jets of cooling air produce respective first and second velocity profiles, each having an average velocity. The arrangement of the first and second nozzles in relation to each other and to the conveyor rollers is such that the velocity profiles of the first and second jets are superimposed one over the other to produce a broader combined velocity profile having an average velocity greater than that of either the first or second velocity profiles.
