Title:
鋼板の制御冷却方法及び制御冷却装置
Document Type and Number:
Japanese Patent JP7196875
Kind Code:
B2
Abstract:
To provide a controlled cooling method and a controlled cooling device of a steel plate capable of cooling a temperature of the steel plate to a target temperature accurately without requiring much labor even when a set flow rate of cooling water used in a temperature estimation model and an actual flow rate do not correspond to each other.SOLUTION: A controlled cooling method of a steel plate includes a measurement step of measuring a temperature of the steel plate on the inlet side and the outlet side of a cooling device at every cut sheet as a virtual control unit of the steel plate produced continuously in a longitudinal direction of the steel plate, an estimation step of estimating the temperature of the steel plate on the outlet side of the cooling device at every cut sheet according to a temperature estimation model by using the measured temperature of the cut sheet on the inlet side of the cooling device and a flow rate set value of cooling water when the cut sheet passes through the cooling device, and a correction step of correcting the flow rate set value of cooling water in a temperature estimation model so that the measured temperature of the steel plate on the outlet side of the cooling device and the estimated temperature of the steel plate on the outlet side of the cooling device in the estimation step correspond to each other over all cut sheets.SELECTED DRAWING: Figure 2
