An upsetting tool for forming continuous cast slab in upsetting presses has one or more first plane upsetting surfaces extending at a slant to a transport direction of the slab being transported through the upsetting press. A second plane upsetting surface extends parallel to the transport direction of the slab and parallel to longitudinal sides of the slab. The first and second upsetting surfaces adjoin one another at a first slant angle. Calibrating upsetting surfaces are provided, and the calibrating upsetting surfaces and the plane upsetting surfaces are positioned above one another.

Upsetting tool for forming continuous cast slab in slab upsetting presses

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. Each upsetting tool has a first inclined upsetting surface and one or more additional upsetting surfaces with angles of inclination which are smaller than the angle of inclination of the first upsetting surface.

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.

Cooling device for the pressing tools of an upsetting press and method

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.
