Description

1. Technical field

[0001] The invention relates to a steel-aluminum composite contact rail for urban rail transit, in particular to a method for manufacturing a stainless steel strip for a steel-aluminum composite contact rail. 2. Background technology

[0002] With the rapid development of rail transit, the quality requirements for rail transit steel-aluminum composite contact rail are getting higher and higher. The currently used contact rail for power supply usually consists of a substrate and a brush surface. The brush surface is connected to the substrate, and the brush surface is made of wear-resistant materials. There are stainless steel strips running along the length of the brush face, wherein each steel strip together with a longitudinal elongate side of the brush face part forms a depression which is at least partially filled with the material of the base body.

[0003] As an important part of the steel-aluminum composite contact rail, the quality of the stainles...
