Abstract
The invention provides a method and a machine thereof, aiming at solving the problems of the existing technology, wherein the method uses the machine to remove original rust-eaten substances on a rail tread, adopts the mode of using calorized steel to form an aluminized coating on the rail tread, and solves the poor track circuit shunting by the excellent high temperature oxidation resistance and corrosion resistance of the calorized steel. The calorized steel has favorable high temperature oxidation resistance, light weight, favorable corrosion resistance and creep resistance and low cost, and the corrosion resistance of the calorized steel in a high temperature H2S media can be enhanced by more than ten times, thereby meeting the requirement of being maintenance free of a railway signaling system. The invention solves the problem of poor shunting, and has 100 percent of effective rate, easy execution, easy and convenient construction and low comprehensive cost.
Description
Technical field
The invention belongs to the railway signal device, particularly utilize the current device that between the equipment of equipment along the line and vehicle or train, passes through.
Background technology
