Through above more known, the rupture pull force of 6 × 19W+21 in the application → 13.2mm has exceeded 190kN, arrive the limiting value that Steel Wire Products Industry material therefor can reach, prepare tensile strength 2700MPa by LX90A material, and zinc layer weight reaches the 60d of steel wire diameter, the steel wire rope of high strength like this, thick zinc layers is determined jointly by its material and preparation technology.
In addition, 6 × 19W+21 → 13.2mm and 6 × 19W+21 → 14mm is the steel wire rope of 2 kinds of different sizes, its requirement is also different, the intensity of steel wire and the identical of 13.2mm in 6 × 19W+21 → 14mm, but the zinc layer weight of steel wire is not identical, diameter 14mm requires that the zinc layer weight of each steel wire is not less than 40g/m
2, 13.2mm then requires that the zinc layer weight of each steel wire is not less than 60 times of (g/m of steel wire diameter
2), because the zinc layer weight of 13.2mm requires higher, the manufacture difficulty of steel wire is also larger than the difficulty of 14mm steel wire rope, and the application successfully overcomes difficulty, has prepared the 6 × 19W+21 → 13.2mm steel wire rope of high strength, thick zinc layers.
The diameter of steel wire rope is different, steel wire diameter in steel wire rope is also different, the diameter of gauge of wire and steel wire rope has geometrical relationship, cannot arbitrarily adjust, but in technological design, consider that the stock of steel wire rope and the gap of stock are worth, and the gap of silk and silk being worth, also having the lay pitch of steel wire rope, the lay pitch of steel stock etc. because usually designing gauge of wire in steel wire rope.
