Embodiment Construction

[0022] The contact wire raw material of the method of the present invention is a ternary copper alloy in which a small amount of magnesium and tin are added to a copper matrix or a quaternary copper alloy in which a small amount of magnesium, tin and rare earth elements are added. Among them, melting magnesium and tin into copper can form a solid solution with copper, aggravate lattice distortion, and play a composite strengthening role. Adding rare earth elements can not only refine grains, increase strength, eliminate or reduce composition segregation, but also improve the electrical conductivity of the alloy. By strictly controlling the addition amount and ratio of magnesium, tin, and rare earth elements, it is possible to improve the strength and electrical conductivity of the material, and at the same time make the alloy material have a high toughness index. Tests have shown that the strength of the above-mentioned ternary or quaternary alloys after upward continuous cast...

Abstract

The invention is concerned with the copper alloy touching line and the preparation method with choiceness integrative performance that uses to improve the using performance of the touching line of the cable technology field. It is: the copper alloy is as the material that the material melts with the following percentage weight, magnesium 0.05~ 0.35%, stannum 0.35~0.05%, total quantity of impurity is smaller than 0.10%, remainder is copper; the above material makes to be the touching line by the steps of smelting, heat preservation, casting pole, pressing, cold rolling, molding rolling. The index of the touching line achieves and overruns the international similar product level, such as the intensity, the conductivity, the elongation ratio, the reverse, repeating bending, convolution.

Description

technical field [0001] The invention relates to a method for preparing catenary conductors used in electrified railways, belonging to the technical field of electric cables. Background technique [0002] In recent years, the operating mileage of electrified railways has developed rapidly. Taking my country as an example, the electrification rate of railways is close to 30%. The general development trend of electrified railways has shifted from mountain fortresses to plain trunk lines, from light loads to heavy loads, and from low speeds to high speeds. From passenger and cargo collinear to passenger and cargo diversion. With the rapid development of electrified railway, the performance requirements of catenary wire, the key component required, are constantly increasing, that is, high strength, high electrical conductivity, weather resistance, wear resistance, good toughness and current-taking effect are required. For this reason, experts in the industry have done a lot of re...
