Definitions
- the invention relates to an upsetting tool for the deformation of continuous cast Slabs in upsetting presses with at least one for the transport direction of the Slab inclined compression surface and one to the transport direction of the Slab and compression surface running parallel to its longitudinal side surfaces, the upsetting surfaces adjoin each other with an inclination angle ⁇ .
- Upsetting presses serve to reduce the width of rolled material, in particular the Slab width in hot broadband roughing lines.
- the upsetting presses indicate this mutually facing pressing tools arranged on both sides of the slab edge on.
- a compression press of the type mentioned at the outset is, for example, from the European one Patent 0 112 516 known and comprises a pair of pressing tools, which are arranged on both broad sides of a slab feed line that your pressing surfaces face each other for pressing a slab.
- One of these Press surfaces is substantially parallel to the slab feed direction another pressing surface has a surface which is oblique to the slab feed direction.
- a vibration unit moves the pressing tool with the parallel and oblique Surface in vibration.
- This known upsetting press further comprises a width control unit to regulate the position of the pressing tool in the direction of the slab width and a controller that detects that the front end of the slab is between the parallel surfaces of the pressing tools is arranged and which then the width control device and after carrying out a specific pressing the vibration unit is actuated.
- EP 0 400 385 describes a flying compression press for reducing the width of slabs in hot broadband apron lines.
- the pressing tools required for slabs are held by a tool carrier.
- a crank mechanism is used to form the reduction drive of the pressing tools provided that acts on a handlebar system, which in the direction of reduction is movable.
- the crank mechanism is arranged in a crankcase, which in one lying press stand is adjustable.
- the upsetting surface This upsetting tool consists of several for the direction of transport of the slab inclined molding surfaces and another compression molding surface, the is arranged parallel to the long sides of the slab. In the direction of the Slab in the upsetting press has approximately the angle of inclination ⁇ of the upsetting surface 19 to 20 degrees.
- the subordinate three transition compression surfaces have one Inclination angle with about 0.9 to 10 degrees and the starting surface of the Upsetting tool has an inclination angle ⁇ of 12 degrees.
- the task is solved with an upsetting tool of the type of Claim 1 designated type in that the upsetting tool both plan Compression surfaces as well as caliber compression surfaces, which are arranged one above the other are.
- This measure creates a combination upsetting tool two pressing positions on one and the same tool, so that even during the Passing a slab through the upsetting press from a calibrating Upsetting can be changed to a flat upsetting or vice versa.
- this has advantages in terms of Flow behavior of the material towards the middle of the slab, so that the so-called dog-bone cross-sectional shape is largely avoided and essentially one rectangular cross-sectional shape.
- the training of tongue and Fish tail at the respective end of the slab can with the invention Upsetting tools can be largely avoided.
- the Angle of inclination ⁇ of the plane upsetting surfaces and the caliber upsetting surfaces to one another correspond. Since the angle of inclination on the upsetting tool includes the Determines the force required for the lateral compression of the slab, it is advantageous to provide the same angle of inclination for the two pressing positions of the pressing tool.
- the caliber compression surfaces of the upsetting tool seen in cross section essentially a U-shape open to the long side of the slab are reproduced.
- the U-shaped caliber compression surface from a flat base and two inclined outwardly opening leg surfaces are formed.
- the Upsetting tool is connected to a tool holder of the upset press and with this perpendicular to the long side surface of the slab up or down in a alternative pressing position to the slab is movable in such a way that the slab width can be reduced either with the flat compression surface or with the caliber compression surface is.
- the combination upsetting tool with its two pressing positions it can be used particularly quickly and variably becomes possible to use the slab during a pass through the upsetting press to optimally reduce the width of two different press surfaces.
- the invention is based on an embodiment for an upsetting tool described in more detail.
- the upsetting tool 1 shown in perspective for the lateral deformation continuously cast slabs 2 is a combination upsetting tool with two Press positions 11 and 12 on the tool.
- the upsetting tool 1 is with a Transport direction 3 of the slab 2 inclined plan compression surface 5 equipped and with another to the transport direction 3 of the slab 2 and whose longitudinal side surfaces 7 parallel compression surface 4.
- the two Compression surfaces 4 and 5 adjoin each other with an inclination angle ⁇ .
- the caliber compression surfaces 6, 6 ' are arranged above the flat compression surface 4, 5.
- the outlet area of the upsetting tool shows an inclined end and flat surface 8, the two parallel to the transport direction 3 of the slab 2 Compression surfaces, that is, the caliber compression surface 6 'and the flat compression surface 4 is assigned.
- the upsetting tool 1 is by means of a self-locking connection with a tool holder 9 at at least four connection points 13 fixed but interchangeable.
- the start of the upsetting tool 1 is the beginning of the upset To see slab 2, which pass through the upsetting press in the transport direction 3 becomes.
- the upsetting tool is equipped with detachable detents 13 connected to the tool holder 9.
- This is with the help of a not shown Lifting device in the direction of arrow 10 perpendicular and parallel to Longitudinal surface 7 of the slab 2 up and down in an alternative pressing position moved to the slab in such a way that the slab 2 either plan with the Compression surface 4, 5 (pressing position 11), or with the caliber compression surfaces 6, 6 ' (Press position 12) can be reduced in width.
- the combination compression tool shown enables - during one Passing a slab 2 through the upsetting press - the side upsetting of the Slab with two different shaped surfaces, so that an optimal one essentially rectangular cross-sectional shape of the slab arises and the in State of the art typical dog bone formation is at least significantly reduced.
