The cross-sectional structure of the wire rope is point-contact round strand, line-contact round strand, surface-contact round strand, shaped strand, single-layer strand non-rotating, sealed and flat, etc. Among them, the surface-contact round-strand steel wire rope is drawn by drawing the line-contact strands through a wire drawing die or a roller die by the traction force of the stranding machine. Through the drawing die, there are two anti-corrosion measures of oil coating and coating in the section strands before and after deformation of the strands.
