Abstract
A method and apparatus for cooling a rod of a coil form, immediately after the hot-rolling thereof and within which the rod, whose loops are spaced a given pitch from one another, is laid flat upon a chain conveyor, and more particularly upon rails thereof, and transported therealong by means of endless chains, includes the cooling of the rod with cooling fluid or air which is introduced from below the cooling floors through means of nozzle portions formed within the bodies of the cooling floors. The method and apparatus features the arrangement and construction, including the configuration, of the nozzle portions thus formed, the cooling fluid being projected upwardly at an angle within the range of 10.degree.-70.degree. with respect to the plane of the cooling bed, and horizontally at an angle within the range of 10.degree.-150.degree. with respect to the transporting direction of the rod, towards the rod directly above the rail and chain portions of the conveyor, as well as being projected upwardly at an angle within the range of 15.degree.-75.degree. with respect to the plane of the cooling bed, and horizontally at an angle within the range of 30.degree.-150.degree. with respec…
