Preparation process of Ti alloy wire rope for marine engineering

Abstract

The invention provides a preparation process of a Ti alloy wire rope for marine engineering. The preparation process comprises the following steps: step 1, electing sponge Ti, sponge Zr, Al shots, anAl-Mo intermediate alloy and an Al-Nb intermediate alloy according to the composition amount, and uniformly mixing the above raw materials; step 2, preparing an electrode by extruding the mixed materials obtained in step 1, cutting off a riser after smelting, and preparing a polished ingot by the adoption of machining; step 3, carrying out wire material preparation by subjecting the polished ingotprepared in step 2 to two stages: hot drawing of a coarse wire and hot drawing at room temperature, so as to obtain alloy fine wires; and step 4, stranding and braiding the alloy fine wires obtainedin step 3 in the form of point contact, so as to obtain the Ti alloy wire rope finally. According to the preparation process provided by the invention, the Ti alloy wire rope is prepared by adopting the Ti alloy material; the corrosion-resistance performance of the Ti alloy wire rope is relatively strong; compared with a steel wire rope, the Ti alloy wire rope has the advantages that the corrosionproblem is solved and the equipment running safety is guaranteed; meanwhile, the maintenance and replacement cost is greatly reduced; and the Ti alloy wire rope is widely applicable to marine engineering and other corrosion environments.

[0002] Corrosion is a prominent problem faced by marine equipment. In my country’s marine engineering and equipment applications, a large number of steel wire ropes are needed, but the corrosion resistance of steel wire ropes is poor. At present, the common method is to galvanize the surface of steel wire ropes. At the same time, related patents are also aimed at corrosion. The problem has been studied, and the existing methods are all realized by coating the surface of steel with a corrosion-resistant coating. However, in harsh environments such as high humidity and high salt in the ocean, there are still serious corrosion problems, which affect the stability and reliability of related equipment. Titanium alloy has excellent comprehensive properties such as high specific strength and good corrosion resistance, especially the natural corrosion rate in seawater is less than 0.001mm / a. It is called "marine metal". Using titanium alloy rope instead of steel wire rope can Realize the maintenance-free life of marine equipment. At present, there are few related reports on the use of titanium alloys to prepare titanium wire ropes. The present invention uses titanium alloys to prepare titanium alloy wire ropes by changing the material method, which is suitable for strong corrosive environments such as marine engineering.
