Alloy ground wire production process

Abstract

The invention discloses an alloy ground wire production process, which relates to the field of ground wire production, and is characterized by comprising the following steps of: S1, raw material preparation: preparing a copper stranded wire and a copper pipe, S2, conducting copper pipe pretreatment, specifically, feeding air into one end of the copper pipe through an air blowing device and blowingthe air out from the other end, S3, raw material core penetrating: penetrating a copper stranded wire into the copper pipe for later use, S4, rolling and reducing: rolling the copper pipe with the copper stranded wire through a rolling mill, and reducing the diameter of the copper pipe by using a roller of the rolling mill, so that the copper stranded wire is hooped by the copper pipe to form anouter sheath, S5, conducting annealing treatment, putting the rolled and reduced alloy ground wire into an annealing cavity to be annealed, and S6, conducting passivating treatment, passivating the annealed alloy ground wire, and then conducting cleaning and blow-drying after passivation. The residual water in the copper pipe can be cleaned through the blown high-pressure gas, so that the situation that the alloy ground wire is exploded due to water vaporization during annealing after rolling is reduced, and the overall production is more stable.

Description

technical field [0001] The invention relates to the field of ground wire production, more specifically, it relates to an alloy ground wire production process. Background technique [0002] Alloy ground wire, also known as through-ground wire, is a signal-specific grounding cable that adopts a unified grounding method for the entire line in the railway signal system. It can ensure the equipotential grounding of the entire line and eliminate the imbalance caused by the potential difference between different devices. current. Since the through-ground wire is connected to the ground and the steel rail, it can meet the requirements of a long-term good grounding resistance value in a large-scale grounding system, and realize effective protection for personnel and equipment. Common alloy ground wires are usually copper alloy sheathed through ground wires, including copper stranded wires, the copper stranded wires are twisted into a whole circular structure by a plurality of soft r...
