Abstract：The axle steel produced by continuous casting technology has some characteristics such as high efficiency，good economy and superior quality. In order to meet the requirements of high quality billets of axle steel by the ministry of railway，the production of axle steel for railway by bloom continuous casting technology was studied. According to the technical conditions of axle steels produced by continuous casting，the action effect of microelement vanadium in axle steel was investigated. The mechanical performance index of axle steel was significantly improved by the precipitation strengthening of vanadium. The strength stability increased by 10%. Moreover，the axle steel exhibited good plastic toughness. The mechanical property and the quality of manufactured axles were good，which could meet the technical conditions of continuous casting and the development demand of railroad transportation.
