Abstract
In this paper, the improved 92-type 12# alloy steel combined frog, which is for 60kg/m steel rail, was taken as the object of study. And then in combination with the problems in its applications in railway lines, this paper analyzed the manufacture technologies of nose rail, wing rail and extended splice rail, from the aspects of structure features, manufacture method and tool selection. Further, this paper proposed some improvement programs of the manufacture processes of nose rail, wing rail and extended splice rail respectively, and carried out the optimization to the current manufacture technology of alloy steel combined frog. Finally, by means of processing experiment, the effect of technology optimization was verified.关键词
