METHOD OF PRODUCING STEEL MATERIAL, APPARATUS THAT COOLS STEEL MATERIAL, AND STEEL MATERIAL

摘要

A method of producing a steel material, wherein when a cooling apparatus having a plurality of cooling sections disposed side by side in a longitudinal direction of a steel material cools the steel material hot worked or cooled/reheated, the steel material is conveyed at a conveyance distance Lo (m) satisfying Equation (1), in one direction along with the longitudinal direction of the steel material, in the cooling apparatus, wherein Lo is defined as conveyance distance (m) of steel material, m is a natural number, and Lh is defined as length (m) of cooling sections in longitudinal direction of steel material:; (m−0.20)×Lh≤Lo(m+0.20)×Lh  (1).
