Abstract

A coil skid on which a hot-rolled coilobtained by coiling a hot-rolled steel sheet is placed includes: at least two or more layers of a metal plateand at least two or more layers of a heat insulating materialeach stacked alternately, in which the metal plateis in contact with the hot-rolled coil. The uneven cooling of an outer peripheral portion of the hot-rolled coil caused by the coil skid is prevented while ensuring the strength of the coil skid, to thereby inhibit the uneven hardness in the longitudinal direction of the hot-rolled coil resulting from this uneven cooling.
