Definitions

  • the invention relates to a device for processing a metal slab, plate or strip, comprising a rolling mill stand with a roll nip between two driveable rolls, the rolling mill stand being designed to roll a metal slab, plate or strip between the rolls.
  • a device of this type is known and is in very widespread use in the metal industry for redacting the thickness of a cast slab, plate or strip and for improving the mechanical properties of a slab, plate or strip.
  • the rolling which is carried out using the device takes place during the processing of thick slabs and plates, usually at elevated temperature. During the rolling of thin plates and strips, the plate or strip is not raised to an elevated temperature prior to the rolling.
  • Yet another object of the invention is to provide a device of this type which is able to improve the mechanical properties in a simple way.
  • a device for processing a metal slab, plate or strip comprising a rolling mill stand with a roll nip between two driveable rolls, the rolling mill stand being designed to roll a metal slab, plate or strip between the rolls, which device is provided with feed means which are designed to guide the slab, plate or strip between the rolls at an angle of between 5° and 45° with respect to the perpendicular to the plane through the center axes of the rolls.
  • shearing occurs over the entire thickness of the slab, plate or strip.
  • This shearing is also more or less constant over the entire thickness. Firstly, this allows grain refinement to occur over the entire thickness. During standard rolling, shearing and therefore grain refinement will only occur at the surfaces.
  • the shearing closes up pores in the metal which are usually formed during the casting of aluminum, for example. Therefore, using the device according to the invention closes up pores over the entire thickness of the material. Both effects are important mainly for relatively thick material.
  • the shearing also causes the eutectic particles which may be present in the material to be broken up, which results in an improved toughness.
  • the feed means which are added to the device in accordance with the invention therefore results, in a simple manner, in an improvement to the material which it produces.
  • Feeding a slab, plate or strip in at an angle also leads to the rolls having an improved grip on the front of the material which is introduced, with the result that the reduction in thickness of the material does not have to be as great as in standard rolling, in which the material is introduced between the rolls at an angle of 0°.
  • the feeding in at an angle also prevents or reduces the "refusal" of a slab, when the rolling mill stand does not take hold of the slab on account of the reduction being too high.
  • JP-A-57 175005 it is disclosed to incline the direction between the centers of the upper and lower rolls of a rolling mill stand in the advancing direction in order to make stable rolling possible with small diameter rolls.
  • the device according to the invention can also be used to roll a slab, strip or plate comprising two or more layers of metal, in which case the metal layers may consist of the same metal alloy, of different metal alloys or of different metals or metal alloys.
  • the feed means are preferably designed to introduce the slab, plate or strip between the rolls at an angle of between 10° and 25° with respect to the perpendicular to the plane through the center axes of the rolls, more preferably at an angle of between 15° and 25°, and even more preferably at an angle of substantially 20°.
  • the shearing is relatively great while the angle is not so great as to impede feed to the roll nip.
  • the feeding can be carried out optimally at an angle of substantially 20°.
  • the feed means comprise a feed surface or a roller table. This easily allows the material to be fed at an angle between the rolls. Other designs of the feed means are also possible.
  • the angle between the feed means and the rolling mill stand is preferably adjustable. This allows the angle to be adapted to the thickness of the slab, plate or strip as desired, for example if the thickness of the material means that a specific introduction angle is desirable. Then, if desired the further rolling using the device can be continued at a different angle.
  • the rolling mill stand is preferably designed in such a manner that, during use, the rolls have different peripheral velocities, the difference in peripheral velocity amounting to at least 5% and at most 100%, and preferably at least 5% and at most 50%, more preferably at least 5% and at most 20%.
  • the difference in peripheral velocity is partly determined by the thickness of the material; in addition, the shearing increases as the difference in peripheral velocity between the rolls becomes greater. Greater shearing is advantageous since it leads to greater grain refinement and improved closing up of the pores.
  • there is a high difference in velocity there is a high risk of slipping between the rolls and the material, which would result in irregular shearing.
  • the rolls have a different diameter and/or can be driven at different rotational speeds. This makes it possible to obtain the difference in peripheral velocity.
  • the device is preferably provided with one or more following rolling mill stands with driveable rolls which are positioned downstream of the rolling mill stand, as seen in the rolling direction.
  • This allows a slab, plate or strip to be subjected to a rolling operation two or more times without interruption, so that a desired result can be achieved more quickly using this device.
  • the material it is also possible for the material to be passed through the same device twice, but this takes more time, particularly when strip material is being rolled.
  • the device is designed, during use, to feed the metal slab, plate or strip to at least one of the one or more following rolling mill stands at an angle of between 5° and 45°, preferably at an angle of between 10° and 25° and more preferably between 15° and 25°, the angle preferably being adjustable.
  • At least one of the one or more following rolling mill stands is designed in such a manner that, during use, the rolls have a different peripheral velocity, in which case the rolls preferably have a different diameter and/or can be driven at different rotational speeds.
  • At least one of the one or more following rolling mill stands has a roll nip which is situated outside the plane of symmetry of the roll nip of the rolling mill stand.
  • support rolls prefferably be arranged upstream of the one or more following rolling mill stands, as seen in the direction of rolling, in order to support and/or guide the metal slab, plate or strip.
  • These support rolls can feed the material to the following rolling mill stands, for example, at the desired angle.
  • the device is provided on both sides with feed means which are designed to pass the slab, plate or strip between the rolls at an angle of between 5° and 45° with respect to the perpendicular to the plane through the center axes of the rolls, preferably at an angle of between 10° and 25°, the angle between the feed means being adjustable between 0 and 45° and it being possible for the rolls to be driven in both directions of rotation.
  • feed means which are designed to pass the slab, plate or strip between the rolls at an angle of between 5° and 45° with respect to the perpendicular to the plane through the center axes of the rolls, preferably at an angle of between 10° and 25°, the angle between the feed means being adjustable between 0 and 45° and it being possible for the rolls to be driven in both directions of rotation.
  • the metal is preferably aluminum or steel or stainless steel or copper or magnesium or titanium or one of their alloys. These are metals which are in industrial use, and it is desirable for them to have good mechanical properties.
  • the figure shows an embodiment of the device 1 with a first rolling mill stand 11 and two following rolling mill stands 12, 13, diagrammatically indicated by a rectangle.
  • Each rolling mill stand has respective rolls 11a,b, 12a,b and 13a,b.
  • Upstream of the first rolling mill stand 11 there is a feed surface 10 over which a slab of metal 2, for example of aluminum, can be supplied.
  • the means for supplying the slab 2 and the means for driving the rolling mill stands are not shown; means of this type are known to the person skilled in this field.
  • the rolling mill stands are arranged in such a manner that rolling mill stand 11 and 13 have a common plane of symmetry P which runs through the center of their respective roll nips.
  • the plane Q through the center axes of the rolls 11a, 11b of the rolling mill stand 11 is perpendicular thereto, as is the plane T through the center axes of the rolls 13a, 13b of the rolling mill stand 13.
  • the rolling mill stand 12 has a plane S passing through the center axes of its rolls 12a, 12b, which is likewise perpendicular to the plane P.
  • the slab 2 is passed at an angle to rolling mill stand 12 and then at an angle to rolling mill stand 13.
  • the feed surface 10 is at an angle ⁇ with respect to the plane P, ⁇ usually being approximately 20°.
  • the angle ⁇ is adjustable and can be matched to the type and thickness of the material.
  • Support and guide rolls 15a,b 16a,b, 17a,b and 18a,b are arranged between the rolling mill stands 11, 12 and 13 in order to guide the slab 2 to the rolling mill stands 12 and 13 after it has been rolled in rolling mill stand 11 and to support it over this path.
  • the rolls 11 a and 11b have different diameters, so that, given an identical angular velocity, they have different peripheral velocities.
  • the rolls 12a, 12b also have different diameters, but in this case the difference in size is reversed. This arrangement means that the shearing in the slab 2 as it passes through the rolling mill stands 11, 12 will have an inverted profile.
  • the material which is displaced during passage through rolling mill stand 11 is, as it were, displaced back during passage through rolling mill stand 12.
  • the rolling mill stand 13 has rolls 13a, 13b with an identical diameter. This stand rolls the slab 2 in the customary way, but it is also possible for the rolls 13a, 13b to be provided with a different rotational speed and therefore a different peripheral velocity. If the latter situation applies, the rolling mill stand 13 will also contribute to the shearing in the slab 2.
  • the device according to the invention can be used to roll slabs, plates and strips of different types of metal, such as steel, aluminum, stainless steel, copper, magnesium or titanium, and it is also possible to roll two or more slabs of metal resting on top of one another.
  • the slabs may consist of different metals or different alloys from one another. If necessary, adjustments which lie within the scope of the person skilled in the art may be made to the device.
  • the device which has been described above and is illustrated in Figure 1 results in a slab, plate or strip being guided through and rolled by the device in the form of a coil.
  • rolling mill stands may also be arranged in other ways with respect to one another, that it is possible to use more or fewer rolling mill stands and that the device can also be used only with rolling mill stand 11.
  • the rolls may also optionally have different diameters and/or be driven at different angular velocities.
  • the supporting and/or guiding of the slab, plate or strip can also be carried out using other means.
  • the feed surface 10 may be replaced by other feed means, such as a roller table, or a single feed roll for strip material, which feed roll has to be arranged in such a manner that the strip material is passed into the roll nip of the rolling mill stand 11 at the angle ⁇ .
  • other feed means such as a roller table, or a single feed roll for strip material, which feed roll has to be arranged in such a manner that the strip material is passed into the roll nip of the rolling mill stand 11 at the angle ⁇ .
  • the slabs were introduced at different angles varying between 5° and 45°, The temperature of the slabs when they were introduced into the rolling device was approximately 450°C. The two rolls were driven at a speed of 5 revolutions per minute.
  • the slabs After rolling, the slabs had a certain curvature, which was highly dependent on the angle of introduction.
  • the straightness of the slab after rolling can to a large extent be determined by the angle of introduction, in which context the optimum angle of introduction will be dependent on the degree of reduction in the size of the slab, the type of material and alloy, and the temperature.
  • an optimum angle of introduction is approximately 20°.
  • the rolling using the method according to the invention results in an equivalent strain which is three to four times higher than with conventional rolling without any difference in peripheral velocity.
  • a high equivalent strain means less porosity in the slab, greater recrystalization and therefore greater grain refinement, and more extensive breaking up of the second-phase particles (constituent particles) in the slab. These effects are generally known to the person skilled in this field of engineering if the equivalent strain increases. Therefore, the rolling according to the invention means that the resulting properties of the material are greatly improved as a result of the use of the method according to the invention.
