METHOD OF APPLYING COOLANT Russian patent published in 2011 - IPC B21B37/44 

FIELD: process engineering.

SUBSTANCE: proposed method comprises applying coolant 8 on rolled material 1 and/or on, at least, one roll 3, 4 of rolling stand 2 with deformation source 9. Constant and stable cooling and lubing conditions ruling out influence of thickness and temperature of material 1 being rolled or rolls are ensured by, first, determining total amount of coolant to be applied depending on power acting in deformation source 9 that is made up of power of, at least, one drive of rolling stand 2 and rolling stand outlet tensioning power except rolling stand inlet tensioning power. Then, amount of coolant for multiple areas 11 is selected depending on distribution of flatness determined using the flatness measurement system 6. Note here that comparison of coolant amount sums such defined is used to determine the difference in amounts of coolant to determine, proceeding therefrom, additional components of coolant amounts for areas 11 allowing for top and bottom boundaries of coolant amounts for areas 11.

EFFECT: stable cooling in rolling.
