Problems solved by technology

In this way, it not only causes a waste of resources, but also hinders the improvement of labor productivity.
In addition, because high-carbon steel has high strength and hardness, the energy consumption and mold consumption in the production process are high, and the broken wire rate is difficult to control. For the above-mentioned many problems, people need to find better solutions

Abstract

The invention discloses a production process of a stainless steel wire rope. The process is characterized in that stainless steel is adopted as a steel wire rope production raw material, and the chemical components of stainless steel include, by mass, 0.012-0.025 % of C, 0.06-0.075% of Si, smaller than 0.03% of P, 0.20-0.30% of W, 15.0-19.0% of Cr, 20.0-23.0% of Ni, 1-1.5% of Mo, 2.50-5.00% of Mn,smaller than 0.03% of S, smaller than 0.1% of Cu, smaller than 0.01% of N, smaller than 0.02% of Ti and the balance Fe and inevitable impurities. The process specifically includes the following stepsof firstly, surface treatment; secondly, drawing; thirdly, normalizing heat treatment and galvanizing; fourthly, drawing; fifthly, stranding to form the rope. The process is reasonable in formula, simple in production process, low in energy consumption, low in fracture rate, high in production efficiency, excellent in comprehensive after-performance, especially large in tensile strength, good incorrosion resistance and worthy of popularization.

Description

technical field [0001] The invention belongs to the field of steel wire rope production, in particular to a production process of stainless steel wire rope. Background technique [0002] With the advancement of science and technology, the amount of steel wire rope is more and more widely used. Among them, high-carbon steel has always been the main raw material of steel rope because of its toughness and strength. Sharply rising, the toughness deteriorates, so in the process of processing, it needs to undergo multiple heat treatments to eliminate its work hardening and ensure the final performance. In this way, it not only causes a waste of resources, but also hinders the improvement of labor productivity. In addition, because high-carbon steel has high strength and hardness, the energy consumption and die loss in the production process are high, and the broken wire rate is difficult to control. For the above-mentioned many problems, people need to find better solutions. Co...
