Abstract: Non-sinusoidal oscillation device of mold is ex- plored and applied. The thoery of no-sinusiondal oscillation is analyzed. The functions of displacement, velocity and acceleration are presented, and the ellipse gears machine is presented too. The spring co-operation is adapted, and makes the machine work with no-impulsion and reduces the power of the motor. The technology parameters and dynamics performance are analyzed. The application in factory shows that this technique has notable effect in reducing the steel leaking, and oscillation trace on the surface of slabs, in making the surface quality of the slabs better, and in improving the pulling velocity of slab.
