Abstract
The titanium steel composite wire rope produced by the method has the characteristics of high strength of alloy steel wire, excellent corrosion resistance and high static friction coefficient of titanium metal. The titanium steel composite wire is manufactured by metal wire rope manufacturing equipment. Each strand of 12 titanium steel composite wires is twisted into a titanium steel composite wire rope by 12 strands. The reason for the high strength of the composite wire is as follows: mainly refines the grain size of the material in the rolling process so as to improve the strength of the wire. The drawing process can produce cold work hardening, and the strength of the wire is further improved. The special requirements of ocean transportation, ocean engineering, oil exploitation, elevator transmission dry friction pairs and the like can be met, and if the special requirements are used as aircraft carrier and aircraft intercepting cables or used as traction ropes of a high-speed elevator car lifting system, the special requirements are matched with a titanium traction sheave, so that the static friction force can be improved by at least five times, the safety coefficient of an elevator is greatly improved, and the equipment maintenance period is prolonged.
