| description | The invention discloses a prestressed concrete sleeper reinforcement raw material hot-rolled wire rod and a preparation method, and belongs to the technical field of metallurgy and controlled cooling processes. The hot-rolled wire rod comprises the following chemical components in percentage by weight: 0.18-0.22% of C, 0.25-0.35% of Si, 0.60-0.70% of Mn, less than or equal to 0.035% of P, less than or equal to 0.035% of S, less than or equal to 0.20% of Ni, less than or equal to 0.20% of Cr, less than or equal to 0.20% of Cu, less than or equal to 0.0080% of O, less than or equal to 0.0060% of N and the balance of iron and inevitable impurities. The tensile strength of the hot-rolled wire rod is 500-550MPa, and the percentage elongation after fracture is not less than 30%. In a bending test (cold bending test is 180 degrees, and the bending center diameter is 1.0 time of the sample diameter), no crack exists, and the good mechanical property is achieved.
