Method for improving twisting quality of large-specification single-strand steel wire rope

The invention discloses a method for improving the twisting quality of a large-specification single-strand steel wire rope. The method comprises the following steps: taking 6-strand or 8-strand steel wire ropes with the diameter of 19mm-22mm as traction ropes; when an external layer of required steel wire is twisted into a single-stranded rope and is taken up, the I-shaped wheel is reversely rotated on the same rope twisting machine to take up the single-stranded rope on the front I-shaped wheel, and then the next outer layer steel wire twisting is performed by taking the single-stranded rope as the center so as to ensure that the steel wire rope is always combined towards one end; each layer of steel wire rope is not off-line after being combined; the single-strand steel wire rope with the required diameter is finally obtained by circulating the steps, and the spool does not need to be put down and turned over repeatedly. When each layer is produced, the steel wires are subjected to'strength breaking 'turnin
