Abstract
A detail thermal model memory has stored detail thermal models each including a mathematical formula using parameters describing a temperature variation of a rolling material in a prescribed cooling interval, an influence coefficient calculator calculate an influence coefficient as necessary for a control of temperature variation of the rolling material, a simple cooling pattern calculator calculate a simple cooling pattern in a simplified form of a preferable detail cooling pattern being necessary for the rolling material to have a preferable material quality, strength, or ductility, a detail cooling pattern calculator calculate a detail cooling pattern of the rolling material in the prescribed cooling interval, and a cooling controller takes the detail cooling pattern as a basis to control a cooling of the rolling material.
