Because of the late development of our industry, the development of the industry has also left many detours, which leads to the technical level of iron and steel enterprises in China still need to be improved. So the recent national major reform goal is phasing out small iron and steel enterprises, vigorously support large-scale iron and steel enterprises to implement technology upgrade, which in large iron and steel enterprises steel rolling production line proposed new requirements. After receiving the design task, by careful thinking and analysis, and the existing equipment, I design this rolling production line. When I finish the elementary design, and the completion of the parts, the design of the steel rolling production line is fully achieved. After a lot of calculation, I found that the new design of the rolling production line is improved, and the stability of the rolling production line is also greatly improved. Its economy is also suitable for the present market demand completely. The design is the related equipment of steel rolling production line, initial design according to the requirements of the task and the need to achieve the purpose to design the rolling line. Firstly, I design and select of the appropriate roll, and select the appropriate roll bearing. Then I design the change roller mechanism and the input of the device and the main motor. Finally, After the calculation of mechanics, the main parts were checked and the design requirements were met, and the design of the whole rolling line was concluded successfully. Keywords: Rolling production line; rolling mill; roller; the bearings  目 录 摘 要 I Abstract II 第1章 绪论 1 1.1 课题的来源及选题的依据 1 1.1.1 基本情况介绍 1 1.1.2 本课题在国内外研究趋势 2 1.1.3 本课题的目的与意义 6 1.1.4 开展研究工作的设想 6 1.2 课题研究采用哪些方法
