摘　　要：钢铝复合轨作为一种新型、高效的导电轨,主要应用于城市轨道交通。与传统的采用低碳钢材料制造的导电轨不同,钢铝复合接触轨充分利用不锈钢的耐磨特性和铝轨本体的导电性,改善受流条件,减小机械磨损和电腐蚀,维护成本低,大大提高经济效益和社会效益。Steel and aluminium composite rail as a new,efficient conductive rail,mainly used in urban rail transport.Different from the traditional conductive rail made of low carbon steel material,steel and aluminium composite contact rail makes full use of the wear resistance characteristics of stainless steel and the conductivity of the aluminium rail body to improve the flow conditions,reduce mechanical wear and electrical corrosion,low maintenance costs,greatly improving economic and social benefits.
