Abstract: A method of and apparatus for continuously quenching a steel plate with cooling water, by passing the steel plate through a water storage vessel containing the cooling water. The cooling water for cooling the upper side of the steel plate is introduced into the upper section of the water storage vessel from an upper portion of the latter and is exhausted from an upper portion of the same through, for example, overflow. The cooling water for cooling the lower side of the steel plate is introduced into the lower section of the water storage vessel from a lower portion of the latter and exhausted from a lower portion of the same. The cooling water is agitated and moved by impellers disposed in the upper and lower sections of the storage vessel in the direction of movement of the steel plate or in the direction opposite to the direction of movement of the steel plate which is clamped and fed linearly through the water storage vessel by means of upper and lower rolls.

Abstract: A nozzle header for cooling plates according to the invention comprises a lower cylindrical header to a lower header chamber therein and having cooling water supply means for supplying a cooling water into the lower header chamber, an upper header in the form of a roof mounted on the lower cylindrical header therealong to form an upper header chamber therein substantially triangular in section communicating with the lower header chamber through apertures formed in an upper wall of the lower cylindrical header, and nozzles extending through the lower header chamber and having upper ends communicating with the upper header chamber and lower ends in the form of nozzle outlets for jetting the cooling water against a surface to be cooled.

Abstract: A continuous hardening device of steel plate of a type wherein steel plate is continuously cooled and hardened by cooling water. The cooling water is continuously supplied into and exhausted out of a water vessel (10) provided in the path of the steel plate for cooling the same. A plurality of rollers (16, 18) supporting the steel plate on the upper and lower sides thereof to feed the same and a plurality of paddle wheels (32, 34) having axial shafts disposed in parallel with the rollers (16, 18) are provided in the water vessel (10).
