    摘要: An FeO layer including fine crystal grains having random orientation is formed as inner layer scale on the surface of the steel wire rod containing C: 0.05-1.2 mass % (hereinafter referred to as “%”), Si: 0.01-0.50%, Mn: 0.1-1.5%, P: 0.02% or below, S: 0.02% or below, N: 0.005% or below, an Fe2SiO4 layer with the thickness: 0.01-1.0 μm is formed in the boundary face between the FeO layer of the inner layer scale and steel, and the thickness of the inner layer scale is 1-40% of the total scale thickness. In another aspect, the maximum grain size of the crystal grain of the inner layer scale is 5.0 μm or below and the average grain size is 2.0 μm or below.
