Study On Technology Of Steel Wire Rope Shaped Strands Ropeway

Tourism resources are rich in China,hills,rivers,mountain,plateau,the terrain is changeable,complex terrain for the development of China's cable industry to create the external environment be richly endowed by nature.Cableway is a means of transportation,is the use of wire rope supporting or traction transport staff and convenient transportation of the goods.The steel wire rope is dominant and the"lifeblood of the ropeway".As an important component of the ropeway rope,its development trend is also more and more obvious,diameter,length and large load capacity,high strength,high toughness,good stability,long service life,environmental protection and clean development of wire rope for ropeway become the target.According to the application condition of wire rope for ropeway rope to make production plan,designed according to the scheme,and the production and use of trial.This paper carried out the main research work and results are as follows:(1)Starting from the chemical composition of raw materials,through the control of C,the content of Mn,P,S and the content of harmful elements to improve the ropeway rope for microstructure of steel wire,steel wire produced by laboratory tests and performance compared with that of common materials,and ultimately determine the tramway wire rope as raw material and special material for cable the rope 70KD.(2)According to the performance requirements of wire rope for ropeway and characteristics,determines the rope with wire production line for steel rolling+drawing+heat treatment+galvanized finish drawing.The steelmaking,rolling part formulates the strict production process parameters,and the optimization of heat treatment process and drawing process,the wire production stage,the steel wire for rope strength uniform,excellent performance.(3)The characteristics of wire rope for ropeway based on the existing equipment conditions and,in accordance with the use of allowable load and safety factor,improve the performance and size of the equipment,the environment and conditions of use to determine the structure,size and performance of wire rope.And then as a condition for design of wire rope and the selection of stock structure,and to determine the various parameters.Design a new shaped strand wire rope structure to replace the original round strand wire rope.(4)The successful development of the design of 6V*33DS,6V*42DS,6V*48DS series cable with special wire rope used to replace the original round strand wire rope for ropeway,and the mass production,and achieved good results,the mechanical properties are far more than the national standard and the rope breaking force higher than the imported products.(5)The series products with the original round strand wire rope for ropeway compared,can significantly reduce the broken wire rope fatigue,reduce the number of possible and outage,prolong the service life of the cableway,especially to solve the trailer rope structure instability problem,realize the cable product upgrade.
