The invention relates to a wire rod processing method, a processing method for an I-type integral oil ring wire rod used in the piston ring industry: rolling: the raw material wire rod is linearly routed through the rolling equipment, and simultaneously rolled on the four sections of the upper, lower, left, and right sides to obtain the obtained product. Cross-section shape is required; annealing: after rolling, the wire rod is linearly routed through an annealing furnace for annealing, and then rolling and annealing are performed after annealing, and this is repeated 3-8 times to obtain a type I integral oil ring wire rod without quenching and tempering. The present invention adopts rolling in four directions at the same time, rolling directly according to the required cross-sectional shape, reasonable distribution of rolling times and rolling volume, ensuring shape requirements, completely avoiding wire bending, oxidation and decarburization, and matrix hardness and plasticity reaching It is a quenching and tempering treatment method based on certain technical requirements, and the product design has high precision in size and shape, excellent quality, and low cost, which can meet the needs of various shapes in large quantities.
