According to relevant information statistics, The countries output of wire rod take amount of the completely hot-roll products 5.3 ～ 15.3 ﹪. In recent years, For the requirement of the surface quality and performance of wire rod, it is more and more higher.So many parameters to be inspected, especially for the chemical composition ,mechanical performance, Crystal microscopic organizes and Crystal microscopic size of wire rod, accord with standard side can be sold out. So new rolling mill and related new technology should be developed fast for the harsh requirement of wire rod. My design is aim to design for wire rod boil Pei rolling mill.First, According to rolling technology , the basic size of roll is designed , and then have selected motor according to rolling force.In main drive system, the strength of roll is also analysed, including the forces given to the rolls. The strength of the frame be analysed clearly.In the aspect of equipment improvments,H-bridle is an episode. During this span of over four months,new conception of machinical design have been improved.But several shortcomings also exist. Professors especially Professor Wang give contributions to me.So I am on behalf of myself to give thanks to all of them. Key-words:produce of wire rod, rolling mill,main drive
