An economical and excellent in processing high-carbon steel wear performance, as the components and wt%: C: 0.60 ~ 0.72%, Si: 0.10 ~ 0.30%, Mn: 0.50 ~ 1.20%, Ca: 0.0030 ~ 0.0070%, cr: 0.60 ~ 0.86%, Als: 0.015 ~ 0.050%, P: ≤0.015%, S: ≤0.008%; steps: smelting and casting into a billet; slow cooling of the slab; heating the slab to; high-pressure water descaler ; hot rolling; cooling the front end; coiling; cooled to room temperature batch annealing; cooled to room temperature pipe; induction heat treatment. Chemical elements of the present invention is simple to use to ensure that the mechanical properties, and by the various parts of the entire volume of the steel strip after annealing can form a uniform globular pearlite, and thanks to the continuous-line induction heat treatment, the steel is heated from the inside, heating speed ratio traditional substantial increase in rate of temperature rise, heat treatment to improve the steel per minute, heating rate and holding time can be significantly reduced to 0.5 ~ 1min, compared with the conventional heat treatment holding time is greatly reduced tendency to grain growth of austenite is small, the surface decarburization, production efficiency can be improved, significantly improved surface hardness.
