Abstract

The invention discloses an ultrahigh strength steel wire rope and a wire drawing method thereof. The ultrahigh strength steel wire rope has a structure of 6*19W+21-phi 13.2mm. The ultrahigh strength steel wire rope comprises a core strand and edge strands. Each one of the core strand and edge strands orderly comprises central steel wires, inner layer steel wires and outer layer wires from inside to outside. The core strand has a steel strand structure comprising three central steel wires, six inner layer steel wires and 12 outer steel wires. The edge strand has a steel strand structure comprising one central steel wire, six inner layer steel wires and 12 outer steel wires. Each one of the central steel wire, inner layer steel wires and outer steel wires of the core strand and edge strands is prepared from a ultrahigh strength steel wire with the diameter of 2.60-2.80mm and a zinc layer with weight of 150-200g/m<2> on the surface of the steel wire by drawing. The wire drawing method simplifies a wire drawing process, steel wires of the core strand and edge strands have small diameter difference and under load, steel wire contact stress is reduced. The wire drawing method easily controls uniformity of zinc coating layer weight. The ultrahigh strength steel wire rope has a large density coefficient, a large breaking force and a long service life.

Description

technical field [0001] The invention relates to a steel wire rope, in particular to an ultra-high-strength steel wire rope and a drawing method thereof. Background technique [0002] Wire ropes are used in material handling machinery for lifting, pulling, tensioning and carrying. The steel wire rope has high strength, light weight, stable operation, and is not easy to break suddenly, and the operation is reliable. The load-bearing capacity of steel wire rope is the most important mechanical performance index of steel wire rope, and the breaking force of steel wire rope is a scientific index that can fully reflect the actual load-bearing capacity of steel wire rope. At present, the breaking force of the 6×19W-WSC-Φ13.2mm ultra-high-strength grade in the GB / T12753-2008 steel wire rope standard for conveyor belts is 148kN. With the expansion of many fields such as aerospace and aerospace, the requirements for the breaking force of steel wire ropes are gradually increasing. T...
