High carbon content 82B wire rods are used to be produced for raw material in deficiency, mainly Wire Rope Production, the stress of steel wire is big, non-deformability
By force, using multi-level during twisting wire rope（By different level）Twisting technology, steel wire cause steel wire rope stress elimination there are bending stress
Bad, steel wire rope endurance and corrosion resistance are low, low relaxation poor performance, it is impossible to meet engineering construction needs.
The content of the invention
The purpose of the invention is to overcome the deficiencies of the prior art and provide a kind of fatigue performance steel wire rope and its manufacture
Method, solves the problems, such as steel wire rope fatigue behaviour low technical, improves service life of steel wire rope.
The steel cord structure of the present invention is 1+9+9+18+18+28+28, by 1, center steel wire, first, second layer each 9
Steel wire, the 3rd, the 4th layer of each 18 steel wire, the 5th, each 28 steel wire primary twistings of layer 6 form, after twisting wire rope shaping
Pre- tensioning stabilization processes are carried out, then carry out highly corrosion resistant plastic coating again.Steel wire is equal with layer diameter in steel wire rope, steel wire
Rope use primary twisting, rather than layering twisting, between steel wire is in line contact condition in steel wire rope, the bending for reducing steel wire is answered
Power.
The present invention includes step is implemented as follows：
（1）The steel wire of the present invention selects the Fine Steel Casting iron gren rod compared with low carbon content with raw material, and grade of steel is 72A or 70#, and
It is not to select 82B or 80#Steel wire rod manufactures, and can so reduce the stress of steel wire and the ability of resistance to deformation, steel wire drawing shaping
Handled afterwards using hot dip zinc aluminum alloy coating, improve steel wire high-corrosion resistance.
（2）Handled after steel wire drawing shaping using hot dip zinc aluminum alloy coating；
（3）Steel wire rope uses primary twisting moulding process；
（4）Steel wire carries out pre- tensioning stabilization processes after being twisted into rope, and steel wire rope carries out in the production of pre- tensioning stabilization processes
Pre- tensioning, pre- tensioning are used and carried out three times, and pre- tensioning for the first time applies 65% that tension force is steel wire rope minimum breaking force, keeps
90 minutes, relaxed state is then slowly offloaded to, and is kept for 6 minutes in this state, it is steel wire that second of pre- tensioning, which applies tension force,
The 60% of rope minimum breaking force, is kept for 70 minutes, is then slowly offloaded to relaxed state, and is kept for 5 minutes in this state, the
Pre- tensioning application tension force is the 55% of steel wire rope minimum breaking force three times, is kept for 60 minutes, is then slowly offloaded to loose shape
State, and kept for 4 minutes in this state, cable wire is after pre- tensioning three times, you can eliminates wire rope structure elongation, it is ensured that its remnants knot
Structure elongation≤0.05 ‰；
（5）Steel wire rope is after pre- tensioning stabilization processes, then carries out lonneal stabilization processes, steel wire rope bear its 50%
Under the tension force of~60% breaking load, temper is carried out at a temperature of 390 DEG C, residual stress can be effectively eliminated, increases creep resistant
Ability, obtains the steel wire rope product of underrelaxation level, it is ensured that steel wire rope looseness rate≤2.0%；
（6）Injection coating treatment is finally carried out to steel wire rope outer layer, injected plastics material uses the highly corrosion resistant with preferable ductility
Plastic cement, 2~3mm of coating layer thickness.
Beneficial effects of the present invention：Steel wire rope is due to using the steel making compared with low carbon content, reducing steel wire stress, and have
One cold twisting technology, pre- tensioning stabilization processes and coating process technology, the stress elimination of steel wire rope is good, improves steel wire rope
Endurance, it is corrosion-resistant, wear-resisting undermine low relaxation performance, effectively eliminate steel wire rope relict texture elongation, improve use
Service life.
