Utilized the correlative knowledge of mathematics and theoretical mechanics, the movement measure of the rolling forming of rectangle ring have been studied that based on the ring rolling theory. And the corresponding geometrical models and mathematical models have been established. It was revealed the variation law of ring in the cold rolling process.With the rolling processing, the inside and outside diameters of ring gradually increased with the cures similarly hyperbolic and the augment speed of the inside diameter was obviously larger than the augment speed of the outside diameter. With the rolling processing, the displacement, speed and acceleration of the ring centre gradually increased in the feeding direction in the horizontal and vertical ring rolling mill. With the rolling processing, the moment of inertia which ring reeled its centre and the whirligig of ring gradually increased. It caused the rotary speed gradually decreased. And it was benefit to decrease the circle tolerance and improve the precision of final molding.
