Production process of medium-high carbon rivet steel wire
By using a roughing borax treatment and segmented heat treatment process, combined with the compounding of catechin compounds and borax, a high-quality borax coating is formed, which solves the problem of insufficient wire smoothness in the production of medium and high carbon rivet steel wire, and improves the quality and connection reliability of riveted parts.

Abstract
The application relates to the technical field of alloy processing, and particularly discloses a medium-high carbon rivet steel wire production process. The steps of the medium-high carbon rivet steel wire production process include: sequentially performing the following on the steel material: (1) borax treatment; (2) heat treatment; (3) pickling and phosphorization; and (4) drawing treatment. The heat treatment comprises the following steps: S1, heating at a heating speed of 20-30 DEG C / min to 730-750 DEG C, and keeping the temperature for 90-120 min; S2, heating at a heating speed of 10-15 DEG C / min to 800-850 DEG C, and keeping the temperature for 60-90 min; S3, heating at a heating speed of 5-10 DEG C / min to 900-930 DEG C, and keeping the temperature for 50-70 min; S4, cooling at a cooling speed of 20-30 DEG C / h to 730-750 DEG C; S5, cooling at a cooling speed of 25-35 DEG C / h to 520-540 DEG C; and S6, cooling, and completing the heat treatment. The medium-high carbon rivet steel wire production process has the advantages that the steel material passability can be improved, and the product prepared by the process is not prone to cracking during cold upsetting.
