Abstract: An upsetting tool of a pair of upsetting tools for the deformation of continuously cast slabs in a slab upsetting press is composed of two connecting rods which are driven through two eccentric shafts and which support the upsetting tool and guide the upsetting tool in parallel direction. Hinged to the connecting rods is a piston/cylinder unit for producing a movement of the upsetting tool synchronously with the slab movement on a roller table. The upsetting tool has upsetting surfaces for acting on one of the two longitudinal sides of the slab. The upsetting surfaces extend parallel or inclined relative to the direction of movement of the slab. The upsetting surfaces are located next to one another so as to form edges extending transversely of the direction of movement of the slab, wherein upsetting surfaces inclined away from the longitudinal side surfaces of the slab are arranged following or possibly in front of an upsetting surface extending parallel to the travel direction of the slab.

The supporting frame includes two housing beams supporting the pair of upsetting slides and, arranged spaced above the housing beams supporting the pair of upsetting slides, two additional housing beams, and connecting beams which connect the respective ends of the housing beams and receive the bearings of the screw-down spindles or the balancing pistons. The individual housing beams form independent structural elements, wherein the housing beams arranged one above the other form a pair of housing beams whose ends have plane side surfaces which can be placed on corresponding plane side surfaces of crossheads which are also constructed as independent structural components and receive the bearings of the screw-down spindles and can be connected by screws to the crossheads.

Abstract: A cooling device for pressing tools of an upsetting press for the width reduction of rolled material, particularly of the width of slabs in hot-rolled wide strip roughing trains. The upsetting press includes two tool carriers which are arranged on both sides of the slab edges. The tool carriers receive the pressing tools and are movable relative to each other. The upsetting press comprises at least one cooling agent nozzle which is directed toward the front edge of each pressing tool.

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.

Abstract: In an upsetting press for reducing the width of rolling stock, particularly for reducing the slab width in hot-rolled wide strip roughing mills with tool carriers, which are disposed on either side of the slab edge and accommodate pressing tools, in order to improve the pressing process, the upsetting press has, in the region between the pressing tools, at least one height-adjustable retaining roll above and at least one below the slab, that driver rolls are disposed in the inlet and outlet regions of the upsetting press above and below the slab and the retaining rolls and driver rolls are provided with internal cooling.

Abstract: An upsetting press for the reduction of rolled material, particularly for reducing the slab width in hot-rolled wide strip breaking-down trains.
