METHOD OF OPERATING COOLING SECTION FOR ROLLED STOCK COOLING, NOT RELATED WITH TEMPERATURE, TO FINITE VALUE OF ENTHALPY Russian patent published in 2014 - IPC B21B37/76 

FIELD: process engineering.

SUBSTANCE: invention relates to metal forming. invention relates to cooling of rolled stock 5 at cooling section 1 with the help of control device 8 fitted with data carrier with computer program. Said control device 8 defines the coolant amount change characteristic K in passage through cooling section 1 for rejection of heat amount corresponding to difference between initial enthalpy EA and final enthalpy EE. Control device 8 feeds coolant 6 to rolled stock section in passage through cooling section 1 in compliance with definite coolant amount change characteristic K. Said characteristic K is defined irrespective of whether temperature finite value TE is reached at the end of coolant feed to rolled stock 5.

EFFECT: simplified control, higher quality.
