Problems solved by technology

[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 stabilit

Embodiment 1

[0035] A preparation process for titanium alloy wire ropes for ocean engineering, comprising the following specific steps:

[0036] Step 1. According to the formula quantity, select the chemical components of the following weight proportions and mix them evenly. See Table 1 below for the chemical component distribution ratios.

[0037] Table 1 Raw material composition ratio

[0038]

[0039] Step 2. Extrude the mixed material in step 1 to prepare an electrode, cut off the riser after smelting, and prepare a light ingot by machining. The light ingot is blanked, forged, and rolled at a temperature of 1100 ° C to obtain a diameter of Φ8. .0mm wire rod;

[0040] Step 3. The light ingot in step 2 is prepared in two stages of thick wire hot drawing and room temperature drawing to obtain alloy filaments. The hot drawing method is: put the wire rod in step 1 into the furnace Through graphite milk before, after ten times of high-temperature drawing: Φ8.0mm→Φ7.0mm→Φ6.0mm→Φ5.0mm→Φ4....

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.
