Definitions
- the invention relates to a roll stand for the production of flat rolled strips with the desired Belt profile elevation, with supported on at least one support roller Work rolls, the work rolls having different diameters have, the thicker work roll is connected to a drive and the runs thinner work roll than "drag roller".
- Rolling mills with different diameters of the work rolls are known.
- a rolling mill is described in US Pat. No. 2,139,872, in which, in order the most effective possible reduction of the rolled strip during rolling reach, two work rolls supported on backup rolls with different Diameter are arranged. It has proven advantageous here only to drive the larger work roll and the smaller roll as a drag roll to let it run.
- Such known rolling mills are advantageously used in the rear stands of a rolling mill used with the aim of reducing the rolling force and the drive power as well as a lower edge drop, especially with high-carbon steef.
- the object of the invention is the known rolling mill with its different Work roll diameters continue to be modified so that a strip is higher Quality is generated and these scaffolds can be used universally.
- the known different sizes Work rolls with a CVC cut (known among other things from DE 37 120 43 C2; the CVC cut or the roller contour follows a polynomial second or higher order) and the work and back-up rolls to be arranged both axially and in the outlet direction received a completely new scaffolding concept that is different from the known ones Roll stands can be used more universally and the rolled strips produce with high flatness and desired belt profile elevation.
- a 5th order polynomial of the general form: R (x) a 5 • x 5 + a 4 • x 4 + a 3 • x 3 + a 2 • x 2 + a 1 • x + a 0
- the work rolls Since the work roll diameters are different, the work rolls have also a different deflection and flattening behavior. specially the effects between the backup rolls and the work rolls are different. This applies in particular to a 3-roll stand, in which only the thinner one Work roll is supported by a backup roll because the thicker work roll any support is missing.
- the contours of the work rolls were therefore designed differently according to the invention to compensate for these effects. The required contour is calculated offline with the goal of creating a symmetrical roll gap under load.
- the new roll stand concept is special in such a case 3-roll stand applicable. These scaffolds can be advantageous, for example for not so high loads then also used for the front scaffolding become. Even with this 3-roll stand, only the thicker work roll is used driven and the thinner work roll runs as a drag roller.
- the thicker Work roll acts as a work roll that transmits a high moment can and which also serves as a backup roller. The combination with the other, thinner work roll supported by a separate backup roll then results in controllable rolling forces.
- the non-driven work roll is also advantageous for the non-driven work roll to be provided with an auxiliary drive, which then uncouples after tapping and / or is switched off. Through this measure the vibrations that frequently occur in the front stands during rolling (Swinging of the work rolls against each other) avoided because then the work rolls are decoupled in terms of drive during rolling.
- the auxiliary drive also provides a benefit that may be necessary allows axial movement of the work rolls during the breaks.
- the work rolls are out in their Wear behavior of different materials or made of highly wear-resistant Materials manufactured, for example after a powder metallurgical Process, preferably the HIP process (hot isostatic pressing).
- HIP process hot isostatic pressing
- the HIP process as it is in the special print from "Stahi” (1998), volume 6, pages 38-40 is described, the material to be treated in special autoclave (HIP systems) at all-sided pressure (up to 200 Mpa) and higher Temperature (depending on the material up to 2000 ° C) warmed up above its yield point and condensed at the same time.
- a four-high stand 10 is shown with two work rolls 1, 2, the are supported on support rollers 3, 4. Below the rolled strip 6 is one.
- Stripper 2 with a larger and above the roll belt 6 a work roll 1 arranged with a smaller diameter.
- the larger work roll 2 is with a Drive 5 provided, while the thinner work roll 1 no drive owns and only through contact with the rolling belt 6 as a "drag roller” starts to rotate.
- the thinner work roll 1 is horizontally displaceable in the direction of arrow 9 arranged and in the illustrated embodiment in the discharge direction 7 of the rolled strip 6 offset by the amount 8 from its original position.
- the contours of the surfaces of the work rolls 1, 2 with their associated Back-up rolls 3, 4 are calculated according to the invention by CVC grinding manufactured according to a polynomial of at least second order (in the illustrated Side view of the roll stand 10, this CVC cut is not visible).
- the upper work roll 1 can for example have a diameter of 400 mm have lower work roll 2 of 600 mm, while the support rolls 3, 4 one Have a diameter of 1350 mm each.
- a 3-roll stand 11 is shown, in which only the upper supports thinner work roll 1 on a support roll 3.
- the thicker and driven one Work roll 2 is chosen so large in diameter that the higher moments can be transmitted and therefore this work roll 2 also serves as a backup roller.
- Fig. 2 is the thinner work roll 1 by the amount 8 in the discharge direction 7 staggered from their original position.
- the upper working salt 1 can a diameter of z. B. 600 mm and the upper backup roller 3rd a diameter between 1400 and 1600 mm.
- the diameter of the bottom Work roll 2, which is also used here as a backup roll, can, for. B. 1400 mm.
- FIGS. 1 and 2 show the application of the invention in two rolling stands.
- the invention can also be based on other roll stands with different numbers of Rolls are used, for example in roll stands with intermediate rolls.
