Problems solved by technology

But this invention has the following disadvantages: the steel wire will be mechanically damaged on the surface during the winding and weaving process. On the one hand, the design tensile strength of a single steel wire is reduced, causing the tensile strength of the entire steel wire rope to be lower than the design value. On the other hand, the damaged part As a result, the steel wire rope is easily corroded in the later use process, which affects the service life of the steel wire rope
The invention has good diameter uniformity, but has the following disadvantages: due to the weak supporting capacity of the sisal core, the steel wire strands wrapped around the sisal core will produce inhomogeneity in support
In addition, there are also mechanical damages in the steel wire production process, and these damages are likely to cause corrosion during the later use of the steel wire rope, which affects the service life of the steel wire rope

Embodiment 1

[0045] Embodiment one: a kind of high-clean stainless steel cable, such as figure 1 and figure 2 As shown, it includes a central steel wire 1 and a plurality of outer layer steel wires 2, and a plurality of outer layer steel wires 2 are helically twisted on the outside of the central steel wire 1, where there may be 6 outer layer steel wires 2, and the outer layer steel wires 2 and the central steel wire 1 form 6+1 structure. A protective steel wire strand 3 is wound and fixed outside a plurality of outer layer steel wires 2 , and the helical direction of the protective steel wire strand 3 is the same as or opposite to that of the outer layer steel wire 2 . The diameter d of the central steel wire 1 0 is 5.9mm, the diameter d of the outer steel wire 2 1 5.4mm, the diameter d of the protective steel wire strand 3 保 is 0.9mm.

[0046] The wire composition of the central steel wire 1 and the outer steel wire 2 is 0.07-0.09%C, 0.7-0.9%Si, 1.0-1.3%Mn, 17.8-18.2%Cr, 9.0-9.5%Ni...

Embodiment 2

[0048] Embodiment two: a kind of high-clean stainless steel cable, such as image 3 and Figure 4 As shown, it includes a central steel wire 1 and a plurality of outer layer steel wires 2, and a plurality of outer layer steel wires 2 are helically twisted on the outside of the central steel wire 1, where there may be 6 outer layer steel wires 2, and the outer layer steel wires 2 and the central steel wire 1 form 6+1 structure. A reinforced steel wire strand 4 is arranged between the central steel wire 1 and two adjacent outer layer steel wires 2, the reinforced steel wire strand 4 is in line contact with the central steel wire 1 and the outer layer steel wire 2, and the reinforced steel wire strand 4 can be a plurality of strands as required. become. The diameter d of the central steel wire 1 0 is 5.9mm, the diameter d of the outer steel wire 2 1 5.4mm, the diameter d of reinforced steel wire strand 4 增 is 1.8mm. The reinforced steel wire strands 4 are helically twisted ...

Embodiment 3

[0051] Embodiment three: a kind of high-clean stainless steel cable, such as Figure 5 As shown, the difference from Embodiment 1 is that a reinforced steel wire strand 4 is provided between the central steel wire 1 and two adjacent outer layer steel wires 2, and the reinforced steel wire strand 4 is in line contact with the central steel wire 1 and the outer layer steel wire 2 , the diameter d of the reinforced steel wire strand 4 增 is 1.8mm. The reinforced steel wire strands 4 are helically twisted together with the outer layer steel wires 2 on the outside of the central steel wire 1 . Compared with Embodiment 1, the advantage is that the reinforced steel wire strands 4 are filled between the central steel wire 1 and the outer layer steel wire 2, and the profile diameter of the entire steel cable does not change, and the reinforced steel wire strands 4 increase the overall strength of the steel cable. In the case of the steel wire strength level, the breaking force of the ...

Abstract

The invention discloses a high-clean stainless steel cable and a treatment method thereof and relates to the technical field of rigging production. The key points of the technical scheme comprise a central steel wire; multiple external-layer steel wires are uniformly distributed outside the central steel wire; a reinforced steel strand is installed at the gap between the central steel wire and adjacent two external layer steel wires; multiple external layer steel wires and the reinforced steel strands are twisted and fixed with the central steel wire as the shaft; the surfaces of the central steel wire, the external layer steel wires and the reinforced steel strands are under surface treatment to form carbonitrided layers. The invention solves the problem that the actual tensile strength of the stainless steel cable is lower than the design strength due to mechanical damage during the wire drawing process, and the overall strength is improved by redesigning and surface treatment of thestainless steel cable structure.

Description

technical field [0001] The invention relates to the technical field of rigging production, more specifically, it relates to a high-clean stainless steel cable and a processing method thereof. Background technique [0002] Stainless steel cables mainly use stainless steel wires to shape the desired product to fabricate steel cables with preset strength. Stainless steel cable has good anti-corrosion ability, so it is used in lifting tools in many occasions. The anti-corrosion ability of the stainless steel cable is that its surface has a layer of chromium-rich oxide film, and the thickness of the oxide film is related to the quality of the anti-corrosion ability. [0003] The prior art refers to the Chinese invention patent whose authorization announcement number is CN103911893B, which discloses a steel wire rope for conveyor belts, which includes a central steel wire, a steel wire layer around the central steel wire, and several outer steel wire strands; the outer steel wire...
