Abstract (en)
[origin: EP3296409A1] In the present invention, when a cooling apparatus (2) having a plurality of cooling sections (head section-cooling headers (21a) to (21c), and a foot section-cooling header (22)) disposed side by side in the longitudinal direction of the steel material cools a steel material hot worked or cooled/reheated, the steel material is conveyed at the conveyance distance L o (m) satisfying Equation (1), in the longitudinal direction of the steel material, in the cooling apparatus (2). In Equation (1), L o represents the conveyance distance (m) of the steel material, m represents a natural number, and L h represents the length (m) of the cooling sections in the longitudinal direction of the steel material. m ˆ’ 0.20 × L h ‰¤ L o ‰¤ m + 0.20 × L h
