Abstract
The slab sizing press is the key equipment for width control of slab, and its basic structure and motion state are the basis for calculating mechanical parameters and presetting rolling parameters.At present, the researches on the basic structure and motion state of walking-stopping type slab sizing press are poor.Hence, a crank slider mechanism is simplified on the basis of the basic structure of walking-stopping type slab sizing press, and a precise kinematic model of the sliding block is established.The ideal state and the motion of the slider are simulated, and the displacement, velocity and acceleration curve of the slab sizing press at different times are obtained.The influences of crank length, length of connecting rod, idle speed and rolling speed on the motion state of the slab sizing press are analyzed.The research provides not only a precise boundary condition for the further analysis of the mechanical state but also a theoretical basis for optimization design of equipment parameters.关键词
