Document Type and Number:
WIPO Patent Application WO/2021/106723
Kind Code:
A1
Abstract:
Provided are manufacturing equipment and a manufacturing method for steel plate that make it possible to perform cooling more uniformly during heat treatment of steel plate and make it possible to manufacture steel plate that is flat and homogeneous. The manufacturing equipment (heat treatment equipment (1)) for steel plate (2) according to one mode of the present invention is manufacturing equipment for steel plate (2), for heat-treating the steel plate (2), wherein are provided a heating furnace (3) that heats the steel plate (2) at 100°C or less, a first shape correction device (4) that corrects the heated steel plate (2) to be flat, a quenching device (5) that quenches the corrected steel plate (2), and a second shape correction device (6) that corrects the quenched steel plate (2) to be flat.
