Document Type and Number:
WIPO Patent Application WO/2023/106047
Kind Code:
A1
Abstract:
A steel plate manufacturing method according to the present invention includes: a temperature measurement step in which the surface temperature of a steel plate is measured over the entire width and the entire length of at least one of an upper surface and a lower surface thereof; an accelerated cooling step in which the steel plate is cooled while being conveyed; a cutting step in which the steel plate is cut into a number of plates corresponding to the measurement result of the surface temperature measured in the temperature measurement step; and a surface hardness measurement step in which the surface hardness of the steel plate is measured over the entire width and the entire length of at least one of the upper surface and the lower surface thereof.
