Abstract

The invention discloses a heat treatment method and system of an SAE1065 steel wire. The method comprises the steps that at the temperature below 300+ / -25 DEG C, the steel wire is loaded, the steel wire is evenly lengthened at the speed of 0.92 mm / min to 1.4 mm / min for 5 min, the steel wire is subject to air cooling to the room temperature, unloading is carried out, and the SAE1065 steel wire obtained after heat treatment is obtained. The system comprises a heating furnace (1), a raw material steel wire winding drum (2) and a finished product steel wire winding drum (3) are arranged on the two sides of the heating furnace (1), the SAE1065 steel wire (4) penetrates the heating furnace (1), and the two ends of the SAE1065 steel wire are wound on the raw material steel wire winding drum (2) and the finished product steel wire winding drum (3); the finished product steel wire winding drum (3) is connected with a power device (7) through a speed reduction device (5) and a transmission mechanism (6), and a brake mechanism (8) is arranged on the raw material steel wire winding drum (2); and according to the method and system, bending fatigue resistance of the SAE1065 steel wire can be greatly improved, and the service life of the steel wire is prolonged.

Description

technical field [0001] The invention belongs to the technical field of heat treatment, in particular to a heat treatment method and system for obtaining high bending fatigue resistance of SAE1065 steel wire. Background technique [0002] Steel wire is widely used in engineering fields. For example, flexible ropes twisted with multiple or multiple strands of thin steel wires are used for lifting, traction, tensioning and load-bearing in production and daily life, such as steel wire ropes for oil drilling and steel wire ropes for cranes. , Steel wire ropes for mines, steel wire ropes for aerial ropeways and steel wire ropes for elevators, etc. The performance and life of steel wire are directly related to the normal operation, life and cost of the equipment, and even directly related to the safety of personal life. [0003] SAE1065 steel wire refers to the steel wire made of high-quality carbon steel with a carbon content of 0.60-0.70% in accordance with the American standar...
