Description
Technical field
The present invention relates to a kind of diameter phi 264mm large oceans engineering steel cord manufacture method, belong to metal product and add
Work technical field.
Background technology
With the continuous development of the industries such as Large-scale Hoisting lifting, ship, excavator, salvaging and Offshore Units, marine steel
The demand of cord will gradually increase, while also propose higher to the Twisting quality, structural requirement and performance characteristics of steel wire rope
It is required that for this Special use environment of ocean, we set about carrying out in terms of ocean is with the production technology of large diameter wire rope
Research, continues to optimize and improves processing parameter, with the quality in kind of my company's marine steel cord product of raising, expands city
, along with I drafts ISO2408 at company《Steel wire rope-requirement》It is required.We by design 6 ×（14×55SWS+6×
36WS）+ IWRC-264 mm producing technique of steel cable and its manufacture method, in process of production, to strand wire twisting parameter
Effectively effective control of control and twisting wire rope parameter, it is ensured that the product twisting quality in kind, successfully develops large-scale
Ocean engineering 264 mm steel wire ropes of φ.The part steel wire rope is sampled to obtain inspection center's test of CNS accreditations, Ge Xiangcan
Number reaches ISO2408《Steel wire rope-requirement》Standard and design requirement.The beginning has been started for large ocean engineering steel cord,
Positive effect will be produced to participate in competition in the international market.
The content of the invention
The purpose of the invention is to overcome the deficiencies of the prior art and provide a kind of diameter phi 264mm large ocean engineerings
With steel wire rope manufacture method, in process of production, by effective control to strand wire twisting parameter and steel wire rope is twisted with the fingers
Effective control of parameter processed, it is ensured that the product twisting quality in kind, solves China and there is no production more than diameter phi 264mm big
Type Marine Engineering Steel cord technical barrier.
The technical scheme is that first twisting metal stock core, then with series connection unit primary twisting outer layer strand, is finally used
Outer layer strand and metal core are into carrying out conjunction rope on rope.
The large ocean engineering steel cord, steel cord structure for 6 ×（14×55SWS+6×36WS）+ IWRC, by
Metal core and 6 outer layer strands are formed.
The present invention successfully develops large ocean engineering φ 264mm steel wire ropes.The part steel wire rope is sampled to be obtained
Inspection center's test of CNS accreditations, parameters reach ISO2408《Steel wire rope-requirement》Standard and design requirement.To be large-scale
Marine Engineering Steel cord has started the beginning, and positive effect will be produced to participate in competition in the international market.
Rupture pull force of the present invention is big, is widely used in Large-scale Hoisting lifting, ship, excavator, salvaging and Offshore Units etc..
Embodiment
It is described in further detail with reference to embodiments：
The steel cord structure of the present invention for 6 ×（14×55SWS+6×36WS）+ IWRC, by a metal core and 6 outer layer strands
Form.
Elder generation's twisting metal stock core of the invention, then uses series connection unit primary twisting outer layer strand, finally with outer layer strand and metal
Wire rope core is into carrying out conjunction rope on rope.
The implementation steps of the present invention are as follows：
（1）Strand manufactures
First 18 × 7+FC-54mm of twisting metals stock core, post-former roller end bend depth as rope away from 8.50 times for strand diameter
1.10 times of stock diameter, then in series connection unit primary twisting（14×55WS+6×36WS）- 84.2mm outer layer strands, post-former
For roller end away from 7.70 times for diameter of restricting, press-bending depth is 0.90 times of rope diameter；
During strand twisting, each I-shaped hub brake rope is adjusted unanimously, curved phenomenon, crimping must not occur before noseplate in steel wire
Watt must compress, fuselage cable-through hole, rear deformation roller must not grooving hinder steel wire, stock surface is smooth, and rope strand, stock oil-free, strand are outputed
Stock stress is checked after 100 meters, pulls out 4 meters for every 1 strand later, checks play torsion in its natural state, all stocks are controlled at -180 °
Within~-360 °, stock stress is strictly controlled on request；
（2）Manufactured into rope
Twisting process parameter：1 × 235- of first twisting metal core φ, 101.6 mm single-strand ropes, the lay pitch are 9.0 times of rope footpath,
Produced with noseplate, rope is then closed on rope-forming machine, wire rope lay pitch is 4.55 times of rope footpath, and predeformation roller spacing is the rope lay pitch
0.85 times, predeformation bends depth as rope 1.0 times of footpath, and Forming die specification is identical with footpath of restricting, and ensures each stock twisting in twisting
Even tension Forming die specification is identical with rope footpath, ensures that each stock stranding tension is uniform in twisting.
The present invention successfully develops large ocean engineering φ 264mm steel wire ropes.The part steel wire rope is sampled to be obtained
Inspection center's test of CNS accreditations, parameters reach ISO2408《Steel wire rope-requirement》Standard and design requirement.To be large-scale
Marine Engineering Steel cord has started the beginning, and positive effect will be produced to participate in competition in the international market.
