Abstract
PURPOSE: To obtain ideal hardened chords without causing hardening irregularities by aligning the centers of plural cooling rings moving the entire part of a hardening and cooling device upward and downward according to the diameters of materials to be cooled and the axial centers of the materials to be cooled and spraying cooling water from nozzles to the materials which are conducted to the device successively.
CONSTITUTION: Five pieces of cooling rings 4W8 suspended to a main pipe 2 installed horizontally by means of pipes 3 are provided, and plural pieces of nozzles 9 disposed radially toward the centers of the cooling rings are projected from the inside circumferential surfaces of the respective rings. The spray nozzle 9 of the 1st ring 4 which contacts the material 10 to be cooled first is provided with inclination tiward the advancing direction of the material 10 in such a way that its axial line direction intersects the axial line direction of the material 10 at 45° or roughly 45° angle. Hence, the water splashes of the cooling water do not backflow and no hardening irregularities are caused.
