Abstract

PURPOSE: To prevent the lower spray nozzles from being deformed and damaged by heat caused by beforehand storing water always in said nozzles at the time of performing normalizing and tempering with the roller quench which quenches and hardens a red hot steel plate by spraying cooling water from upper and lower spray nozzles while allowing the same to pass between upper and lower rollers.
CONSTITUTION: While a red hot steel plate 1 is being transferred along the pass line 2 between upper and lower rollers 3, 7, the cooling water is sprayed from upper and lower spray nozzles 5, 8 onto the top and bottom surfaces of the steel plate 1, whereby the steel plate is quenched and hardened. In the case of performing normalizing and tempering of steel plates, etc. with this roller quench unit, the upper spray nozzles 5 are lifted to the upper part together with a header 6 so that they will not receive the thermal effect of the steel plate. Since the lower spray nozzles 8 can not descend, water is supplied to the lower nozzles 8 by operating the small-size pump 22 in the water feed line 20 from a water collecting pit 16 and is let to overflow from the ends of said nozzles, whereby the deformation owing to heat is prevented, the unevening of cooling of the steel plate at the hardening eliminated and the hardening prevented from becoming defective.
