Background technology
Steel wire rope is used in material carrying machine for promotion, traction, tension and carrying.The intensity of steel wire rope is high, conducts oneself with dignity
Gently, stable working, be not easy whole root fracture suddenly, reliable operation.The bearing capacity of steel wire rope is the most important mechanical property of steel wire rope
Energy index, and the rupture pull force of steel wire rope is the Scientific Indicators of an actual bearer ability that can reflect steel wire rope comprehensively.Currently,
The rupture pull force of 6 × 19W-WSC- Φ 13.2mm Extra High Strength grades in GB/T 12753-2008 steel wire rope used for conveyer belt standards
For 148kN, however as steel wire rope in multiple fields such as metallurgy, mine, petroleum gas drilling, machinery, chemical industry, aerospaces
Extension, the requirement to breaking force of rope is gradually increased.The rupture pull force of client's needs is often not achieved in existing standard
190kN, the requirement of the not small 60d of zinc layer weight of steel wire.The current steel of steel wire rope used for conveyer belt of this superhigh intensity, thick zinc layers
The material of the SWRH82A of cord production, 6 × 19W-WSC- of production Φ 13.2mm, rupture pull force 190kN, zinc layer weight 60d
Difficulty is big, it is necessary to be innovated in raw material, galvanized steel wire production technology.
Invention content
The present invention is directed to overcome the deficiencies of the prior art and provide a kind of SWRH92B materials, superhigh intensity zinc-coated wire is produced
Method, include that the production technology of zinc-coated wire, including wire drawer are drawn in being arranged of the technological parameter of hot-dip galvanizing steel wire, thick zinc layers
The formulation of skill, the selection of wire drawing die pass structure, the selection of wire drawing powder, the formulation of wet-drawn wire technique and emulsion and wire drawing die
The selection etc. of pass structure, it is ensured that the rupture pull force of steel wire rope and reach 190kN, naked rope aging rupture pull force with glue rupture pull force
