Abstract

The invention discloses an annealing process for high-performance metal wire production in the technical field of metal wire annealing processing; the annealing process comprises the following steps of: wire pretreatment, sectional heating, secondary drawing and secondary annealing; cleaning and processing a wire to be processed firstly when the wire is pre-treated to ensure that an oxide layer onthe outer wall of the wire is cleaned, wherein the annealing process for the high-performance wire production increases the pretreatment step for the wire, reduces the impurity content of the wire during the process, applies prestress to the wire before thermal treatment, improves the subsequent annealing effect, and carrying out sectional heating treatment to eliminate network carbide of the material, greatly improve the fatigue life and tensile strength of the material, and enable the quality of the metal wire to be more stable; meanwhile, ultrasonic vibration treatment is adopted during heating, so that the transformation speed of the metal material to a stable austenite single-phase region is improved, and the thermal treatment time is saved.

Description

technical field [0001] The invention relates to the technical field of annealing processing of metal wires, in particular to an annealing processing technology for producing high-performance metal wires. Background technique [0002] Metal wire usually uses metal wire rods and metal rods as raw materials, and passes through professional equipment such as wire drawing equipment and annealing equipment. After drawing, annealing and other processes, it is processed into various wire (wire) products of different specifications and types, and the obtained products are called metal wires. [0003] At present, the development direction of metal wire is generally developing towards high quality, high performance and multiple varieties, so as to meet the current increasing performance requirements such as high temperature, high load, high speed and corrosion resistance. The commonly used annealing process includes the steps of entering the furnace, heating, heat preservation, rapid ...
