specific Embodiment approach

[0023] A kind of embodiment of the production process of the catenary anchor wire rope of the present invention comprises the following steps:

[0024] A. Surface pickling and phosphating treatment: select high-quality high-carbon steel wire rod, put the high-carbon steel wire rod into the pickling tank, use the chemical reaction between hydrochloric acid and wire rod to remove the scale on the wire rod surface, and enter the phosphating tank after high-pressure washing. Soak in phosphating solution at 70°C-80°C for 5-10 minutes, so that the surface of the wire rod is covered with a layer of phosphate coating, saponified after washing with water, so as to facilitate steel wire drawing;

[0025] B. Drawing: the phosphating wire rod obtained in step A is drawn in separate passes in a water tank type wire drawing machine to obtain steel wires of predetermined semi-finished product specifications;

[0026] C. Lead bath heat treatment: heat the semi-finished steel wire drawn in ste...

Abstract

The invention discloses a production process of a contact net anchorage steel wire rope. The production process comprises the following steps: carrying out surface acid cleaning and phosphating; drawing; carrying out lead bath heat treatment; galvanizing; drawing; detecting; entwisting; stranding; forging; and greasing. The production process has the advantages of convenience in operation and time-saving and labor-saving properties; and the produced contact net anchorage steel wire rope has the advantages of high breaking force, long fatigue service life, good abrasion resistance and good corrosion resistance.

Description

technical field [0001] The invention relates to a production process of a catenary anchor wire rope. Background technique [0002] At present, the steel wire rope used on the anchor tension device of the electrified railway catenary drop pulley includes 156 steel wires. Due to the small number of steel wires, low density coefficient, and large twisting stress between strands, when in use, The wire rope is easy to rotate, and at the same time, the contact area between the strands is small, the surface is uneven, and the fatigue life is small. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages and provide a production process for catenary anchoring steel wire rope with convenient operation, time-saving and labor-saving, high breaking force, long fatigue service life and good wear resistance and corrosion resistance. [0004] The purpose of the present invention is achieved through the following technical solutions...
