Abstract
A method of operating an upsetting press for reducing the width of a hot slab cast in a continuous casting plant by laterally pressing the slab between the pressing tools of the upsetting press which are moved toward each other and away from each other by an eccentric lifting member as the slab moves on a roller conveyor through the upsetting press. During the time phase in which the pressing tools have no contact with the slab, the slab is accelerated from a predetermined feeding speed and is subsequently decelerated to this predetermined feeding speed, reducing the upsetting of the slab.

In a method of operating an upsetting press for reducing the width of a hot slab cast in a continuous casting plant by laterally pressing the slab between pressing tools of the upsetting press, the method including moving the pressing tools toward each other and away form each other by means of an eccentric lifting member as the slab is moving on a roller conveyor through the upsetting press, the improvement comprising, during a first time phase in which the pressing tools have no contact with the slab, accelerating the slab from a predetermined feeding speed and subsequently decelerating the slab to the predetermined feeding speed, and reducing the upsetting of the slab during a second time phase in which the pressing tools have contact with the slab prior to the acceleration of the slab.
