In this paper, the rol l ing car design of finishing mill onAn shan ste el2150 hot-rolled strip steel plate production line was presented. According original designed, roll changing car was moved bya chain system and a ratchet system. The process was plicated and it spends a lotof time on roll er changing. After it was redesigned , roll er changing time was shortened and efficiency was highly improved. This paper outlines the development of domestic and international situation of the roll ing car and its development direction. I mainly design ed rolling car for PC main roller mill. Itu sed motor to provide electrical power so that s procket on the output shaft of reducer can roll on the sprocket fixed chain . So rolling car could move along the orbit. Itu ses hydraulic cylinders to pull hook around the pin rotation, or push or pull hook, so that pulled out or push in the work roll. R oll ers changed work could be eventual ly realiz ed. In the process of designing a car , the drive n scheme design , working principle statement, lubrication and environmental protection and economic analysis have been done. The paper mainly focuses on the structural design of car, the choice of motor and working parameters, the calculation and verification of the ponents. ? On the basis of consulting the relevant materials and using forefathers' experience for reference, through the design and analysis of rolling car , every indicators reache s the demand s, this design has a certain va
