Abstract

The invention discloses an aluminium material for contact nets on a rapid transit railway and a manufacturing method thereof. The aluminium material comprises the following components by weight percent: 0.83%-0.9% of silicon, not more than 0.18% of iron, 0.04%-0.07% of copper, not more than 0.05% of zinc, 0.78-%-0.85% of magnesium, 0.12%-0.2% of chromium, 0.45%-0.6% of manganese and not more than 0.1% of titanium, and the balance of aluminium and impurities brought while the aluminium material is manufactured. The manufacturing method of the aluminium material comprises the steps of casting, annealing, extruding and quenching. In the invention, the aluminium material has a performance exceeding the international standard, high tensile strength ab of not less than 330, high yield point Q0.2 of not less than 310 and high elongation rate S of not less than 13% and improves the corrosion stability, the impact toughness and the bending property.

Description

technical field

[0001] The invention relates to a material and a manufacturing process of a special aluminum material for a high-speed railway catenary. Background technique

[0002] Catenary is a huge space mechanical system, which uses components to achieve orderly connection and connection, and connects contact wires, catenary cables, support devices, insulating components, electrical equipment and pillars into a system that can transmit electric energy and has support. Functional, yet mechanically robust system as a whole. This system should be able to withstand the invasion of various meteorological conditions in nature and ensure good power transmission to electric locomotives running at high speed.

[0003] The components of the catenary are the joints and links of the catenary system. Any damage to the components of the catenary means the destruction of the power supply system, which will paralyze the overall operation and power supply system. In a certain sense, c...
