Embodiment Construction

[0022] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0023] Example figure 1 As shown, this embodiment provides a 9×21Fi+PWRC (FC)-Φ8mm high-nitrogen nickel-free super duplex stainless steel wire rope for high-speed elevators and its manufacturing method. The steel wire rope includes outer strand 1, inner strand 2 and center Strand 3, outer layer strand 1 and inner layer strand 2 are made of high-nitrogen nickel-free super duplex stainless steel. ~0.48%N, ≤0.012%C, 0.12%Ce or Y, ≤1.0%Si, ≤0.01%S, ≤0.02%P, ≤0.01%B, the balance is Fe; the central strand 3 is made of polypropylene fiber material;

[0024] The outer layer strand 1 uses 9 filled steel wire strands. The strand structure is 10+5F+5+1, the strand diameter is 1.97mm, the strand lay length is 16.5mm, and the strand twist is leftward. When plying, a rear deformer must be used. The deformation roll distance is 30mm, the reduction is 2.2-...

Abstract

The invention provides a high-nitrogen nickel-free super double-phase stainless steel wire rope for a high-speed elevator and a manufacturing method thereof. The high-nitrogen nickel-free super double-phase stainless steel wire rope comprises an outer-layer strand, an inner-layer strand and a central strand, wherein the outer-layer strand and the inner-layer strand are made of high-nitrogen nickel-free super double-phase stainless steel materials, and the central strand is made of polypropylene fibre materials; and protective grease is filled between the central strand and the inner-layer strand or between the central strand and the outer-layer strand and between the inner-layer strand and the outer-layer strand. According to the invention, the cost of a product is reduced, the contact stress between the stainless steel wire rope and a wheel groove is reduced, the strength is high, the wear resistance and the safety are greatly improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to a high-nitrogen nickel-free super duplex stainless steel wire rope for high-speed elevators, and also relates to a manufacturing method of the high-nitrogen nickel-free super duplex stainless steel wire rope for high-speed elevators. Background technique [0002] Steel wire rope is one of the oldest and widely used mechanical components. Steel wire rope can provide high load capacity and change the direction of force transmission, so it can be used for various purposes such as fixing ropes, tying ropes, slings, and transmitting motion. At present, due to the increase of high-rise buildings, the large-scale use and rapid development of high-speed elevators have brought about more and more quality and quantity requirements for elevator traction stainless steel wire ropes. However, ordinary stainless steel wire ropes have poor bearing capacity, large diameter, broken The problems of low tensile force, high elongation, poor wear re...
