preparation Embodiment 1

[0031] The chemical composition of the stainless steel of this embodiment includes by mass percentage: C0.04, Si0.80, Mn0.30, P0.05, S0.04, Cr15.0, Ni22.0, Mo1.0, Ti3.0, B0 .15, W0.45, RE0.04, the balance is Fe and unavoidable impurities.

[0032] The specific production process is:

[0033] Step 1. Surface treatment Put the ￠5.5mm raw wire rod on the pay-off frame, remove the hot-rolled scale through mechanical descaling equipment, then enter the cleaning tank for cleaning, pickling in the pickling tank, and then enter the cleaning tank for cold and hot water Rinse, then enter the boron coating equipment for boron coating treatment, and finally enter the drying equipment for drying to obtain pretreated wire;

[0034] Step 2, drawing Put the pretreated wire obtained in step 1 on a drawing machine for multi-pass drawing to obtain a semi-finished wire, and take up the wire with an I-shaped wheel;

[0035] Step 3, normalizing heat treatment, galvanizing Place the semi-finished ...

Abstract

The invention relates to a stainless steel wire and a production process thereof. The stainless steel wire rope is characterized that stainless steel of specific components is used as wire rope production material and the wire rope production material is subjected to surface treatment, drawing, normalizing heat treatment, zincing, drawing, and stranding to obtain a finished wire rope. The stainless steel wire rope and the production process thereof have the advantages that production steps are few, energy consumption, die consumption and wire breakage rate are low, labor productivity is high, and the wire rope is well resistant to corrosion.

Description

technical field [0001] The invention relates to a steel wire rope, in particular to a stainless steel wire rope and a production process thereof. Background technique [0002] Due to the high strength, good toughness, and fine and uniform heat treatment structure of high carbon steel, which can meet the needs of drawing, twisting and performance uniformity, it is used as raw material in the traditional steel rope manufacturing industry. The processing route is roughly as follows: removing hot-rolled scale from raw wire rods—dry drawing—(intermediate heat treatment) normalizing—dry drawing (compression rate is about 92%)—(intermediate heat treatment) lead bath Isothermal decomposition - galvanizing - wet drawing (compression rate is about 97%) - twisting strands. However, because of its large work hardening coefficient (that is, after the compression rate exceeds 85% during processing, the strength rises sharply and the toughness deteriorates), so in the processing process, ...
