Abstract

The invention discloses a drawing process of a long-diameter high-carbon wire. A draw wire has a diameter of 14mm and carbon content of larger than 0.82%; by using the drawing process, a finished product steel wire having a diameter of 5.65mm is drawn, total drawing compression rate is larger than 82%, steel wire drawing speed is 2-3.5m / s, the maximum part compression rate and maximum absolute deformation of steel wire drawing can not be in the same drawing pass, the maximum absolute deformation does not exceed 1.4mm, and the highest steel drawing temperature does not exceed 130 DEG C. According to the invention, after being drawn, the steel wire is high in tensile strength, good in tenacity and high in comprehensive quality.

Description

technical field [0001] The invention relates to a large-diameter high-carbon wire drawing process, which belongs to the technical field of metal product processing. Background technique [0002] High-performance steel wire and products not only require high enough strength, but also require good fatigue resistance and high yield. Drawing is the first cold drawing large deformation process of steel wire, which determines the performance of steel wire. Research shows that during the drawing process, the deformation resistance is very large, so a large amount of heat will be generated due to material deformation in this process. According to the literature, about 90% of the mechanical work in the drawing process is converted into heat. Therefore, the instantaneous temperature rise caused by heat generated by deformation and friction cannot be ignored, and may even become a key factor affecting and restricting product quality and production efficiency. Especially in the produc...
