METHOD OF OPERATING COOLING SECTIONS WITH DETERMINATION OF VALVE CHARACTERISTICS AND STRUCTURES RELATED THEREWITH Russian patent published in 2013 - IPC B21B45/02 

FIELD: process engineering.

SUBSTANCE: cooling section 1 has multiple coolant outlets 2 to feed coolant in normal operating conditions to rolled material 3 fed there through. Said coolant is fed in required amount to required point and at due time by feeding coolant 4 to said outlets 2 via feed channels 5 and main pipeline 6 shared by all feed channels 5. Said channels 5 are equipped with valves 7 to stop coolant fed to outlets 2 and to initiate it. Said valves are automatically driven by appropriate device 8 to feed coolant in compliance with process chart. Said device allows for particular operating characteristic of said valve. In testing said cooling section, said specific characteristics is checked up by opening and closing valve 7 to define time variation in coolant flow by appropriate meter 12 arranged main pipeline 6.

EFFECT: higher accuracy of characteristics.
