Abstract:
In rolls of winding equipment in a hot-rolling factory, each roll includes a lower cladding layer formed on the surface of the roll barrel and a self-fluxing alloy layer formed on the lower cladding layer by thermal spraying and containing carbide particles dispersed therein. The lower cladding layer includes an Fe-based cladding layer which has a Shore hardness of 60 or greater and which contains, in terms of mass %, 0.1-0.4 C, up to 2.0 Si, up to 3.0 Mn, 1.0-15.0 Cr, and 2.5-5.0 Ni. The lower cladding layer further contains one or more of Mo, V, and Co, the contents of Mo, V, and Co being 0.1-5.0 mass %, 0.1-3.0 mass %, and 0.5-5.0 mass %, respectively.
