Definitions
- the invention relates to a roll stand with, if necessary, directly or supported by an intermediate roller to a backup roller, in particular axially displaceable in opposite directions, cylindrical over its entire length Work rolls, with at least one roll along its length yielding differently, in particular on at least one partial area is formed with a larger flattening behavior and in that extending between roll pin and roll surface Area at least one notch running concentrically around the axis having.
- this area can edge sharpening for strips of 1250 mm on an edge strip of about 15 to 40 mm width, which in the case poor friction between the rollers and the rolling stock, like him often due to the rough rollers in the last stand of a tandem mill occurs at a distance of more than 40 mm from the band edges Can enlarge area. It is therefore usually a Part of this sharpened edge area of uneven thickness removed by trimming the tapes. This trimming is with you further work step and thus corresponding costs as well as with an additional share of scrap.
- each of the movable rollers over at least part of the length of the Roll bale a deviating from a straight line parallel to the axis, curved contour, which preferably extends over the entire length of the roll barrel and the contours of the two Rolling the pair of rollers only in a certain axial position the rollers complement each other without gaps.
- the invention has for its object a roll stand of the beginning to create the type mentioned, with which the strip edge pressure and reduce edge sharpening while avoiding band tears to let.
- the invention makes it possible in the end section with greater flexibility of the roller, both a larger flattening as well as ovalization of the roller than in the rest of the area cause.
- a larger one can be found in the less compliant area achieve an effective work roll radius with a corresponding decrease, so that the band area assigned to this has a greater finished length than the adjacent part of the band. It can be done simultaneously perform an isolated tape edge treatment. Because that Roll flattening behavior in the area of the strip edges can be done in this way change that an indirect flat edge flatness control is achieved becomes.
- FIG. 1 One at least in its one end region with a larger flattening behavior of the bale formed cylindrical roller 10 is shown in FIG. 1.
- From one end 5 of the roller Here is one side around the axis of rotation of the roll or the journal 12 concentrically extending notch 6 is provided.
- the coat close Axis area 7 is in the area of the wedge-shaped notch 6 hollow.
- the roll axis is closer Notch surface 9 parallel to the roll axis, while the roll shell closer Notch surface 11 tapers to the notch base 13.
- the Roll shell shape 14 of the roller body is in the region of the notch a continuation of the contour of the roller part in full cross section, here a cylindrical shape.
- Figure 2 shows the paired arrangement of the work rolls 10, the each have the notch 6 on one side in their end faces 5.
- the rollers 10 can be axially displaced in opposite directions be that the respective score 13 in a more suitable Position to the respective band edge 15 is located. This will be here achieved by the notch 13 in the position shown approximately in Height of the band edges 15 is arranged. Because of the Material recess missing internal support of the jacket near each Area 7 is in the rolling process in contrast to a full body of rolls at the band edge 15 a significantly higher in comparison This band area is flattened. This causes the edge pressure reduced, the tape thickness in the width direction is evened out and consequently minimizes edge sharpening. Through the less sharpened belt edges can wear the rollers be reduced. It is both the scrap portion through the so far necessary trimming of those that no longer fall within the tolerance range Band edges reduced as well as the life of the used Rolls increased.
