And we carry out national standard during the production .We use continuous rolling technology ，there is 18 mill in common ,6 for roughing mill ,6 for medium mill ,6 for finishing mill . The largest end mill speed is about 16m/s .This paper also analyzed the contemporary rod production in China. A series of problems to be solved are put forward. The design bases on the design paper, which firstly states the development. The necessity and possibility of setting up a plant are also discussed. Then the design is set out in certain procedures, mainly including the making of product outline, choosing mills, choosing pass system, designing of pass in typical products force and energy parameters calculating and checking, auxiliary equipment, choosing workshop arrangement.
