2、重点零件进行校核。在此基础上，再对系统的其 他非标准零部件，如：旋转上料器，移钢机等重要部件，进行结构的设计和计 算。按上述方法完成的设计能很好的完成芯棒旋转冷却的任务。 关键词：关键词：芯棒；冷却；钢管；方案 III Abstract With the rapid development of MPM and the improvement of demand for steel pipe at home and abroad, the output of steel pipe is steadily on the increase, and the amount of Mandrill i

According to the requirements and the fundamental principle of cooling system, the paper chose the first as a selection of the design, by a detailed analysis and comparison of working principle ,as well as advantages and disadvantages of the three proposals. Through consultancy to relevant materials, analysis and calculation the paper determines the model of motors, reducers, shaft, coupling, keys, and other important parts,and checks up the important parts. On this basis, th
