Abstract

The bullet wire cable and its production process features that medium carbon steel SWRH32A steel or 25#-55# steel is used as the material to produce bullet wire cable via surface treatment, drawing, normalizing heat treatment, zinc plating, re-drawing and twisting. The present invention has the features of less production steps, low power consumption, high production efficiency, etc.

Description

Technical field: [0001] The invention relates to a steel wire rope, in particular to a medium-carbon 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 pro...
