COILING TEMPERATURE CONTROL APPARATUS AND COILING TEMPERATURE CONTROL METHOD

摘要

A coiling temperature control apparatus of the present invention includes a cooling headers priority order calculation unit for calculating and outputting a priority relationship among opening sequences of cooling headers of a cooling device, so that cooling speed of a rolled strip in the course of being cooled will satisfy a target value for the cooling speed, a cooling headers priority order memory unit for storing the priority order for each cooling header outputted by the cooling headers priority order calculation unit, and a control command calculation unit for predicting the coiling temperature of the rolled strip from a target coiling temperature, information on speed of the rolled strip, and the information stored into the cooling headers priority order memory unit, and using a strip temperature prediction model for predicting the coiling temperature of the rolled strip, and calculating and outputting each header pattern for accomplishing the target coiling temperature using the prediction result of the coiling temperature, each header pattern being a combination of the open/close of each cooling header.
