Production line of high-speed train contact leads

Abstract

The invention discloses a production line of high-speed train contact leads. The production line comprises a skip elevator, a melting furnace, a holding furnace, a continuous caster, a corner remover, a polishing machine, a roughing mill, intermediate scissors, a finishing mill, a cleaning machine and an automatic rod winding machine which are sequentially arranged according to a work process. The skip elevator lifts a skip to a certain height to send materials to the melting furnace for melting, after a copper liquid is melted and refined, the copper liquid is sent to the holding furnace and is further sent to the continuous caster for casting, coarse products produced by the continuous caster, after being processed by the corner remover and the polishing machine, are sent to the roughing mill, the intermediate scissors and the finishing mill for processing, and impurities such as copper ashes and the like on the surfaces of the products are cleaned by use of the cleaning machine, and finally coiling is performed. The production line provided by the invention has the following advantages: the automation is high, the production efficiency is high, the delivery is convenient, the diffusion area and the diffusion speed of a deoxygenization dehydrogenating agent can be conveniently controlled, and the deoxygenization dehydrogenating effect is improved.

Description

[0001] technical field [0002] The invention relates to the field of deep processing of copper products, in particular to a high-speed train contact wire production line. Background technique [0003] With the rapid development of my country's national economy and the continuous acceleration of electrified railways, the requirements for the contact wire materials of electric locomotives are getting higher and higher. It has high tensile strength, strong material hardness and mechanical properties such as high temperature resistance and wear resistance, so as to ensure the speed and safety of train operation. [0004] Copper has very low resistivity and good corrosion resistance, making it an ideal wire. Both copper and copper-silver alloy wires have been industrialized, but the tensile strength and softened strength indicators of these two materials have not yet met the requirements. Therefore, other alloy components need to be added. [0005] In fact, the raw material...
