Problems solved by technology

[0002] At present, customers in the market have higher and higher requirements for the ellipticity of the 1×19 structural steel wire rope. However, the 1×19 structural steel wire rope is a “cc” type steel wire rope. In order to control its looseness, a straightener is simply used as a debugging method in conventional production. , the reduction is very deep, and the ellipticity of the finished steel wire rope reaches more than 4.4% of the thickness of the steel wire rope, which cannot meet customer needs

Embodiment 1

[0024] This embodiment provides a method for preparing a 1×19 structural steel wire rope, and the specific steps are as follows:

[0025] Step 1: select a smooth steel wire with a diameter of 1.60mm, and draw the 1.60mm smooth steel wire through a hot-dip galvanizing process to preferred monofilaments with a diameter of 0.35mm and 0.325mm.

[0026] Among them, the composition and weight percentage of the steel monofilament are: the content of carbon is 0.3% to 1.15%, the content of manganese is 0.1% to 1.1%, the content of silicon is 0.1% to 0.9%, and the content of sulfur and phosphorus does not exceed 0.15%, the chromium content is 0.2% to 0.4%, the copper content is 0.2%, and the others are iron.

[0027] Step 2, select a monofilament with a diameter of 0.35mm as the first steel wire monofilament 1, select a monofilament with a diameter of 0.325mm as the second steel monofilament 2; combine 1 first steel monofilament 1 with 6 second steel wires The monofilament 2 is placed...

Embodiment 2

[0037] This implementation discloses a 1×19 structural steel wire rope, such as figure 1 As shown, it is prepared by using the preparation method of the 1×19 structural steel wire rope in Example 1.

[0038] Specifically, the 1×19 structural steel wire rope includes 1 first steel monofilament 1 , 6 second steel monofilaments 2 and 12 third steel monofilaments 3 .

[0039] Among them, 6 second steel monofilaments 2 are evenly distributed on the peripheral side of the first steel monofilament 1 to form a core strand structural strand; 12 third steel monofilaments 3 are evenly distributed on the periphery of the core structural strand side.

[0040] The experimental data shows that the 1×19-Φ1.59mm galvanized steel wire rope prepared in Example 1 has an ellipticity of 0.04 when the thickness of the steel wire rope is 1.58-1.62, and the ellipticity of the steel wire rope can be effectively controlled at 2.5% of the thickness of the steel wire rope within.

Abstract

The invention provides a 1 * 19 structure steel wire rope and a preparation method thereof, and the preparation method comprises the following steps: twisting and stranding one first steel wire monofilament and six second steel wire monofilaments into a core strand structure plied yarn; using a stranding machine to twist and strand the core strand structure plied yarns and 12 third steel wire monofilaments into a 1 * 19 structure steel wire rope; wherein the ratio of the over-twisting rotating speed of the stranding machine to the rotating speed of the machine tool is not lower than 0.2 and not higher than 0.3; a steel wire rope of a 1 * 19 structure penetrates through a plurality of straighteners, and the adjacent straighteners are vertically placed. By strictly controlling the ratio of the over-twisting rotating speed of the stranding machine to the rotating speed of the machine tool and reasonably using the straightener in a matched mode, the ovality of the galvanized steel wire rope of the 1 * 19 structure is improved, and the ovality of the steel wire rope can be effectively controlled within 2.5% of the thickness of the steel wire rope.
