Novel double-compacted steel wire rope and production technology thereof

Abstract

The invention relates to a novel double-compacted steel wire rope and a production technology thereof, and aims to provide a steel wire rope which is stable in physical property and is compacted tightly as well as a production technology of the steel wire rope. All pickled and phosphatized steel wires are drawn for the first time, then annealed, dried and drawn again after dried, and various finished steel wire products are formed. Third center steel wires, inner-layer steel wires, filling steel wires and third outer-layer steel wires are twisted and then rolled, steel wire rope first outer-layer strands are produced and twisted on the outer side of a rope core in a wrapping manner, a steel wire rope is twisted, the twisted steel wire rope is forged, and the forged steel wire rope is warehoused. The section area of each steel wire rope first outer-layer strand after rolling is 8%-10% smaller than that before rolling, and the section area of the steel wire rope after forging is 10%-13% smaller than that before forging. The rope core adopts 7*7 independent steel cores.

Description

technical field [0001] The invention relates to the technical field of steel wire rope production, in particular to a novel double-compacted steel wire rope and its production process. Background technique [0002] As compacted strand steel wire ropes become more and more popular in the domestic market, most domestic manufacturers have started research and development on compacted strand steel wire ropes. The domestic market competition for compacted steel wire ropes is also becoming more and more intense. At present, most of the steel wire ropes in the domestic market are compacted strand steel wire ropes. Only the steel wire rope strands are compacted during the production process. There is no big difference between the twisted steel wire rope and the ordinary steel wire rope. This type of steel wire rope is only compacted once. If the rope strands cannot be tightly compacted, the wear resistance and service life of the wire rope will be affected to a certain extent durin...

AI Technical Summary

Problems solved by technology

At present, most of the steel wire ropes in the domestic market are compacted strand steel wire ropes. Only the steel wire rope strands are compacted during the production process. There is no big difference between the twisted steel wire rope and the ordinary steel wire rope. This type of steel wire rope is only compacted once. The rope strands cannot be tightly compacted, and the wear resistance and service life of the wire rope will be affected to a certain extent during use.
