Abstract
PURPOSE: To economize energy consumption and to prevent the damage of a rolled stock following a rapid change of a cooling water temp. by performing supplying and stopping a required medium for each nozzle system.
CONSTITUTION: The cooling water injected from a pump P is branched for each nozzle system 2, 2..., after its pressure is controlled by pressure control valves 6, 6..., injected toward a rolling roll 1 from nozzles 2. At that time, the cooling water branched for each nozzle system, passes through each heat exchanger 10, 10... disposed for each system and then its temp. is controlled individually. That is, as to the heat exchanger of which an on-off valve 11 is opened among each heat exchanger 10, 10..., the cooling water passing through it, is cooled by the heat transfer medium to become a low temp. cooling water. The cooling water passes through the heat exchangers with unopened on-off valves, is not cooled by the heat exchange 10 and in a state as a high temp. cooling water passes through the pressure control valves 6, then injected from the nozzles 2 toward the rolling roll 1.
