Railroad rail anticorrosion and surface conduction enhancing method

Abstract

This invention is about a method to antisepticize railway and increase its surface conductivity, which contains only two steps: 1. use high pressure gas to eject high-speed hard granule to the railway surface, in order to make a deoxidated rough coat on it; 2. metal spraying, use method of combustion or electric arc to fuse the metal alloy thread constantly moving on the railway surface, add a driven nozzle when it reaches to the melting point, spray the molten alloy onto the railway surface. The combustion method mentioned refers to autogenous welding and the electric arc method refers to adding a voltage between two alloy thread and keeping them moving constantly at an angle. The alloy thread discharges and becomes melting at the point of intersection. The advantage of this invention is it is suitable on the outside, meanwhile low cost, short machining period, easy to carry away, safe operation and strong adhesion between the rail surface and worked coat.

Description

technical field [0001] The invention relates to a method for anticorrosion and surface conduction improvement of railway rails. Background technique [0002] Because the rails of the railway are laid in the open air, affected by the weather environment of rain, sun, and temperature difference between day and night, a layer of oxide layer, that is, rust will be formed on the surface. The layer will continue to intensify, and the rail is the conductor for the driving signal to be transmitted to the traction locomotive, so serious rust will affect the accuracy of the driving signal transmission, and will cause major accidents in railway transportation. For many years, people have adopted many methods to solve this problem. There are many methods to deal with the rust of railway rails, but due to the limitation of construction conditions and the requirement of cost, a good method that is really feasible has not been found yet. Contents of the invention [0003] The purpose of...
