A plate-like stock material is rolled or edged to a desired width on an edging stand of an edger. The edging stand is equipped with a pair of vertical rolls. The central axis of at least one of the vertical rolls of the edging stand is tilted within a suitable angle range toward the same direction as the advancing direction of the stock material or toward the direction opposite to the advancing direction of the stock material in a vertical plane parallel to the advancing direction of the stock material. The resulting downward bending deformation is received by a table roller.

A large gauge high strength steel rod having a diameter of not less than 9 mm, is produced from high carbon steel containing, by weight percent, from 0.65 to 0.90% carbon and from 0.15 to 1.5% chromium capable of being drawn without subsequent heat treatment.

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 respect to the direction of the transportation of the rod, towards the overlapped, sidewise circumferential portions of the rod. Thus, uniform cooling may be achieved over the entire length of the coiled rod.
