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. The rod mill belongs to the small steel rolling category. The rod mill is same with other mills, its main engine row also includes the implementing agency, the transmission device, and the driving force three basic building blocks. This design in the collection reorganized the domestic and foreign advanced rod rolling equipment and in the technical foundation, carries on the choice and the appraisal to the design proposal. First, according to assigns depresses the regulations and the rolling speed computation roll force and the roll torque, and has carried on the choice and the examination to the electrical machinery. Then, has carried on the stress analysis and the essential examination regarding the main spare part. Regarding main drives in reduction gear, the shaft coupling, the rotary coupling spindle have carried on the design, simultaneously has carried on the choice to the lubrication way. Finally, carries on the analysis appraisal to this rolling mills ec
