Title:
STEEL PLATE COOLING METHOD AND DEVICE, AND STEEL PLATE MANUFACTURING METHOD
Document Type and Number:
Japanese Patent JP2021133400
Kind Code:
A
Abstract:
To achieve homogenization of a steel plate in a longer direction when performing accelerated cooling processing.SOLUTION: A temperature gradient is applied in a longer direction of a steel plate S in first cooling equipment 10 on the basis of cooling property in the longer direction of the steel plate S during the plate is transported to second cooling equipment 20 from the first cooling equipment 10, a steel plate temperature of the steel plate S, which is transported to the second cooling equipment 20 from the first cooling equipment, is measured, and the accelerated cooling for the steel plate S is performed by the second cooling equipment 20 so that a cooling completion temperature in the longer direction of the steel plate falls within a set range TR on the basis of the measured steel plate temperature.SELECTED DRAWING: Figure 1
