Definitions
- the invention relates to a support roller according to the preamble of claim 1 and a rolling stand according to claim 6.
- Generic back-up rollers are used, in particular, in rolling mills for rolling metallic flat goods, in particular hot or cold strip, fine strip or film.
- a roll stand which usually has two work rolls and at least two support rollers supporting the work rolls, these products are rolled to the desired strip thickness. Due to the high forces occurring perpendicular to the roll axes there is a deflection of the roll axes, which leads to lack of dimensional stability of the product and undesirable band properties.
- the back-up roll according to the invention intended for use in a rolling mill comprises, in a first manner known per se, two bearing journals and a bale extending therebetween. With the journals, the support roller is rotatable in a frame and optionally driven driven.
- the bale which has a substantially cylindrical basic shape, is provided with a non-cylindrical outer contour, which is symmetrical to the center line of the bale and forms a so-called crown as a whole.
- the bale in the region between the center line (ML) and the edge region in longitudinal section in each case two parabolically shaped outer contour regions whose Curvature is in opposite directions, the apex of the curvature of the adjoining the edge region outer contour region to the roll axis and the vertex of the curvature of the adjoining to the center line of the bale outer contour region facing away from the roller.
- Such a support roller is simple and inexpensive, for example by grinding, produced.
- the basic roller characteristic is not changed even in a roll grinding, as is the case for example with VC rolls.
- the design according to the invention also counteracts quarter buckles and compensates profile errors by an improved rolling force distribution, in particular in the case of narrow strips to be rolled.
- the two parabolic regions continuously merge into one another.
- a particularly preferred embodiment results when the transition between the two parabolic regions lies midway between the center line and the edge region. As a result, a particularly uniform and homogeneous contour is obtained.
- E is the functional height or the so-called Encore, that is the maximum addition to the nominal radius of the roller in the area of the center line (maximum of crowning). This means that the radius of the roller parabolic decreases from the center line to the center between the center line and edge region after the above function.
- the Encore or the maximum addition is determined in advance for each application, for example by simulation of the rolling process by a FEM calculation.
- the invention further relates to a rolling stand for hot and / or cold rolling of metallic strip, strip and / or film, which can be operated in the one-way or Reversier rehearsal.
- this rolling mill has at least one work roll and at least one support roll as described above. However, preferably at least two work rolls and at least two backup rolls according to the invention are provided, each work roll being supported by a support roll.
- the invention relates to a rolling mill with at least two rolling mills arranged one behind the other as described above.
- the in the Fig. 1 shown backup roller 1 has two bearing journals 2 and 3, between which the actual roller body 4 extends.
- the roller body 4 has on both sides of the bearing pins 2 and 3 adjoining edge regions 5 and 6, which do not come into contact with the rolling stock during rolling of the rolling stock.
- Between the edge regions 5 and 6 extends the bale W, which has a substantially "cylindrical" outer contour.
- Essentially cylindrical means that of the ideal shape of a cylinder deviating outer contour, although according to the invention is not straight cylindrical, the deviations, the so-called crowning or radial elevation, but is numerically low compared to the roll length.
- a typical backup roll has a length of 1800 mm, while the maximum radial elevation is in the range of a few ⁇ m to a few 1/100 mm.
- the back-up roll after the Fig. 1 is symmetrical to the centerline ML constructed and has a nominal diameter Dnenn, which corresponds to the ideal cylindrical contour of a roller.
- the roller 1 has a non-symmetrical outer contour in the form of a crown, which is also arranged symmetrically to the center line ML and forms a crown, which is in lateral view or in longitudinal section through the support roller highest height on the center line ML and the functional height or the "Encore "E represents.
- This function height is specified as a function of the material to be rolled and the rolling parameters such as stitch loss or the like.
- the radial elevation drops in each case and reaches zero at the ball edges.
- the two regions 7 and 8 are curved in opposite directions.
- the region 7 has a curvature whose vertex points away from the roll axis, while the curvature of the region 8 is formed so that its vertex points toward the roll axis.
