Definitions
- the invention relates to a method for influencing the profile of rolled strip to be cold rolled in at least one roll stand.
- a corresponding roll gap enlargement can also be achieved in the strip edge area by turning off the rolls at the end of the bale.
- edge drop formation by moving the work rolls in accordance with the belt edge. If the formation of edge drops is not counteracted, the rolled strips do not achieve the required strip thickness tolerance over the entire width, so that they cannot be used in this form.
- the invention has for its object to provide a method with which the formation of edge drops can be minimized.
- This cooling can take place, for example, by applying liquid nitrogen to the strip edge regions.
- the strip edge regions are guided through U-shaped housings arranged on both sides of the strip, within which the coolant is applied to the strip edge regions.
- the strip edges of the unrolled strip are thus brought to a lower temperature before they enter the first or the first roll stand.
- the rolled material becomes harder at the strip edge regions, so that it is more difficult to deform. It also contracts a bit at these low temperatures, so it gets thinner.
- this low temperature of the strip edges also affects the bale ends of the rollers that come into contact with them, because the diameter in this area is reduced by the strong cooling. Together, this results in a summation of influences which lead to the band at the band edge regions relative to the central region of the band less rolling, which consequently leads to a significant reduction in edge drops.
- the solution according to the invention is particularly advantageous compared to the known methods because, on the one hand, for example, no complex design of the roll stands is required, as would be required for the work roll displacement.
- cooling boxes are arranged on both sides of the strip to be rolled, which bring the strip to a lower temperature in the opposite strip edge areas as it passes through the strip. With these strongly cooled strip edges, the strip then runs into the roll stand and is rolled there in the usual way, the occurrence of edge drops being prevented or at least substantially reduced by the influences described above.
