All continuously the cold company rolling mill may enhance productivity 30~50%, the product quality and becomes a useful adult rate also obtains the very big enhancement. Along with the industrial production development, the antipode thin strip request increases is specially the micro electron industry antipode thin strip request is higher. But the rolling thin belt requests the roller diameter to be smaller. This design has carried on the improvement design in view of some factory cold rolling production line in main body equipment rolling mill, also the original four rollers change five rollers, to improved after the roller and the rack and so on the major parts has carried on the intensity examination. In the design, first to designed the rolling mill the plan to carry on the choice and the narration, then has calculated when the rolling needed strength and moment of force, thus had determined the host electrical machinery capacity, and has carried on the examination to the electrical machinery. This design also systematically calculated depress the system: The housing pin main parameter, its driving moment and convert on the electrical machinery the static torque, had determined depress the nut the size and to depress the nut to carry on the examination. To the rack size, the stress have carried on the computation and the intensity examination. The antithetical couplet coupling spindle also carried on the computation, the analysis has calculated the flat head, and has carried on the intensity computation to it In finally, to the entire rolling mill lubrication method, the test run method and has carried on the narration to the control system, and has carried on the economic efficiency analysis to it. After the computation and the examination, after the improvement rolling mill satisfies the technological requirement, the improvement five roller structure is reasonable.
