Patent ID: 8382916

Claim:
A method for production of a steel product, said method comprising: (i) heating and hot rolling a steel billet into a steel wire: (ii) descaling the steel wire with high pressure water at 3 MPa or higher at least once before finish rolling; (iii) winding up the hot rolled steel wire at 750 to 1000° C.; (iv) introducing the steel wire immediately after winding in a wet atmosphere comprising steam and/or water mist having a particle diameter of 100 μm or less, thereby oxidizing the surface of steel wire; (v) passing the steel wire through the wet atmosphere for 0.1 to 60 seconds; (vi) performing the oxidization at a dew point of from 30 to 80° C., (vii) setting the completing temperature of the oxidation at 600° C. or higher, wherein said oxidation forms scale which has a Fe 2 SiO 4 (fayalite) layer in contact with said steel billet wherein the Fe 2 SiO 4 (fayalite) layer has a thickness in a range of from 0.01 to 1 μm.
