Heat treatment: The wire rod is subjected to annealing treatment to reduce its hardness, eliminate internal stress, and make it have better plasticity, which is convenient for stretching.

Ii. Wire drawing and wire processing stage
This is a crucial step in drawing thick wire rods into thin steel wires, which determines the diameter and strength of each individual wire.
Rough drawing: Use a wire drawing machine to gradually stretch the treated wire rods through dies of different hole diameters, reducing the diameter to the intermediate specification (such as from 10mm to 2mm).
Medium drawing and fine drawing: Continue to draw through a more precise die to make the steel wire diameter reach the final required specification (can be as fine as less than 0.1mm). During the process, annealing is required multiple times as needed to prevent the steel wire from breaking due to brittleness.
Surface coating (optional) : In some scenarios, the steel wire is galvanized or nickel-plated to further enhance its corrosion resistance or electrical conductivity.
Iii. Strand Twisting Stage
Multiple fine steel wires are twisted together according to specific rules to form "strands", providing a basic unit for the subsequent rope formation.
Strand structure design: According to the load-bearing requirements of the steel wire rope, determine the structure of the strands (such as Silu type, Warrington type, and filled type) and the number of steel wires (such as 1×7, 1×19).
Twisting processing: Use a twisting machine to twist multiple steel wires around a central wire (or without a central wire) in a clockwise or counterclockwise direction to form strands with certain strength. At the same time, control the twist length (the helical spacing of the strands) to ensure stability.
Four. Rope twisting stage
Twisting multiple strands of steel wire into the final stainless steel wire rope is the final core step of the process.
Rope structure design: Determine the number of strands of the steel wire rope (such as 6×19, 6×37) and the twisting method (right cross-twisting, left same-direction twisting, etc.). Different structures correspond to different flexibility and load-bearing capacity.
Rope twisting: On the rope forming machine, multiple strands of steel wire are twisted around the central strand (or fiber core, steel core) to form a complete steel wire rope. During the process, the tension needs to be controlled synchronously to ensure uniform force distribution on each strand and prevent deformation of the rope body.
Pre-deformation treatment (optional) : Pre-deform the steel wire rope after it is formed to eliminate the internal stress generated during twisting and prevent loosening or twisting during use.
