Title:
COIL SKID, AND METHOD FOR MANUFACTURING STEEL PLATE
Document Type and Number:
WIPO Patent Application WO/2021/066141
Kind Code:
A1
Abstract:
In this coil skid, on which hot-rolled coil 1 obtained by winding a hot-rolled steel plate is placed, at least two layers of each of a metal plate 11 and a heat insulating material 12 are stacked alternately, and the metal plate 11 comes into contact with the hot-rolled coil 1. By preventing uneven cooling of an outer circumferential portion of the hot-rolled coil as a result of the coil skid, while maintaining the strength of the coil skid, uneven hardness in the longitudinal direction of the hot-rolled coil, occurring as a result of such uneven cooling, is suppressed.
