Definitions
- the invention relates to a roll stand with, if necessary, directly or supported by an intermediate roller to a backup roller, in particular work rolls axially displaceable in opposite directions.
- 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 rolling stand of the generic type
- the invention makes it possible in the section with higher compliance the roller has both greater flattening and ovalization of the roller than in the rest of the area. By doing less compliant area, a larger effective one Reach the 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 a perform isolated tape edge treatment. Because the roll flattening behavior in the area of the strip edges can be changed that an indirect flat edge flatness control is achieved.
- An embodiment of the invention provides that the roller from one roll core extending over a partial length of the bale exists, which has a lower modulus of elasticity than one roller jacket enveloping him. If such a roller, for example in a roller section from a combination of the roller core with lower (e.g. gray cast iron) and a roller jacket with a higher one Modulus of elasticity (e.g. steel) and in an adjacent section consists entirely of the material of the roller shell, oriented on the belt edge is used, both the band-centered Flatness as well as largely independent of the flatness of the Affect band edges.
- the roller from one roll core extending over a partial length of the bale exists, which has a lower modulus of elasticity than one roller jacket enveloping him.
- At least a roller in which there is between the journal and roller surface extending area at least one concentric about the axis running notch is provided.
- This constructive design allows especially an isolated strip edge treatment.
- the mode of action the roller is based on the different flattening behavior of the roller body provided with the concentric notch with the resultant hollow cladding Roll area or the full body of the roll adjoining the roll center. Due to the notch on one or both sides according to the invention can the larger flattening in the area of the strip edges due to the lack of internal support due to the material cut-out of the roll area close to the jacket.
- roller according to the invention Only provide flattening at one end of the roller or journal. It can then be used in a preferred combination with a Identical other, axially movable roller ensure that a band edge-oriented positioning largely independent of the bandwidth can be made because of such interference of the flattening behavior on each roller and thus occurs on both band edges.
- the notch In the case of a notched roller, the notch preferably runs from the front towards the middle of the roller.
- the length of the Notch can be applied to the different rollers and the required rolling properties of the rolling stock for optimal influencing the flattening behavior of the rollers and the effect on the Band edges, d. H. Reduction of edge pressure and avoidance of Edge sharpening, be adjusted. Another optimization results itself by the advantageous opposite axial direction already mentioned Moving the pair of rollers.
- the resulting material recess in the edge area of the Roll a roll area close to the jacket and an inner axis near the axis Roller area.
- the roll area close to the jacket is corresponding the notch is hollow, d. H. this close to the coat It is in the roll area when the elastic material behavior is used possible, in the event of external loads caused by the rolling process Evade cavity. Consequently, the outer contour of the roller in flattened this area.
- This configuration is not here on a concentric, annular notch per face of the Bounded roller body. It is still possible that several concentric notches in one end of the roller body are introduced.
- the shape of the concentric notch is basically arbitrary. It is preferably based on the desired characteristic of the roller body and is optimal with finite element calculations predictable.
- the radial axis is closer to the roll axis Notch surface parallel to the roller axis, while the Notch surface closer to the roll shell tapers to the notch base.
- both those closer to the rolling axis run as well as the notch surface closer to the roll shell parallel to Roller axis to the notch base and thus have one over the Cross section seen constant distance from each other.
- the notch is not runs essentially parallel to the roller axis, but from their frontal incision area in the direction of the roller axis or extends in the direction of the lateral surface, d. H. divergent or is designed to be convergent.
- the outer contour of the notched roller can be chosen as desired. In the unloaded state, the outer contour of the roller part is included Full cross-section in the outer contour of the notched edge area continued. It can be z. B. a cylindrical or a barrel-shaped roller with conventional crowning. Nevertheless, special shapes are conceivable, such as a CVC cut. Basically, the shape and nature of the lateral surface are Roller not restricted; it can take any course.
- roller notched according to the invention is more suitable band edge-oriented positioning due to the in the area of Belt edge lacking inner support of the roll shell a larger Flattening is experienced and, as a result, the strip edge is sharpened reduced
- another aspect of the invention provides overall elasticity the edge area of the roller body on the choice of Material or composite material of a filler element that the Fully or partially filled notch, variably adjust to can.
- the overall elasticity of the edge area then sets additive from the elasticity of the roll body shell and the elasticity of the filling element together.
- the material of the filler element has a lower modulus of elasticity than that of Roll body, thus a more elastic roll edge area adjust.
- the filling element can preferably be used as a plug or as a sleeve provide for the or the notch or other recess of the roller body inserted or inserted from the edge becomes.
- the filler element As a material for the filler element, d. H. for the stopper or the sleeve can be steels with better elastic properties use as the roller material; continue to use of other metals, high temperature plastics or the combination of materials come into play. This makes it possible to Possibility of varying the flattening behavior of the rolls in their Increase edge area. Furthermore, the advantageous arises Effect that the parts of the roller that are not in contact with the belt, but are in support contact, less strongly through a walking process be claimed. To influence the flattening behavior of the rollers and their adaptation to the properties and needs of the goods to be rolled is carried out with such Insert elements of the damping influence of the accordingly chosen Material of the filling element used.
- the principle of the roller which yields differently over its length can also be done according to another proposal of the invention realize that on at least one roll neck a sleeve a material with a different modulus of elasticity than the rest Roller body is arranged. If one roller after another Execution according to the invention a roll shell of different Total thickness is continuously compliant due to the gradual change in roll shell thickness.
- Slidable rollers 1 consist of one over a Part length of the bale-extending roll core 2, the lower one Has a modulus of elasticity as a roll shell enveloping it 3. While the roller core 2 consists of gray cast iron, for example, the Roller jacket 3 z. B. be made of steel. The higher flexibility of the material of the roller core 2 causes in this section Roller 1 both a larger flattening and ovalization of the Roller than in the adjacent area that continuously from the less compliant material.
- FIG 2 Another embodiment shown in Figure 2, at least in its an end area with greater flattening behavior of the bale trained cylindrical roller 10 is shown in Figure 2.
- From the one end face 5 of the roller is one side around the Roller axis of rotation or the axle 12 concentrically running Notch 6 provided.
- This material cut-out results in in the roll body a roll region 7 close to the jacket and an inner one Area near axis 8.
- the area near axis 7 is in the Area of the wedge-shaped notch 6 lying hollow.
- the notch surface 9 closer to the rolling axis runs parallel to the roller axis, while the notch surface 11 tapered to the notch bottom 13.
- the roll shell shape 14 of the Roller body in the area of the notch is a continuation of the Contour of the roller part in a volatile section, here a cylindrical shape.
- Figure 3 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.
- FIG. 4 A modification of the roller 10 is shown in Figure 4.
- the roll shell shape 14 in The area of the notch 6 is like the contour of the roller part in the Full cross section cylindrical.
- a Notch cavity used partially filling plug 16 This ensures that the roller region 7 close to the jacket is only partially hollow, d. H. is only supported locally. This is in the case of the roller 10 shown in FIG. 5, in which an inserted one is used Sleeve 17 with an adapted elasticity remaining there Sheath area 7 completely filled.
- roller 100 shown by a on the roller or journal 12 pushed on sleeve 18 reaches a lower modulus of elasticity has as the material of the remaining roller.
- the journal 12 can be cylindrical or dashed as in the sleeve 18 hinted conical, which is a correspondingly adapted Contour of the sleeve bore presupposes.
- pairs roller 200 shown is the principle of different along the bale Flexibility on more than two roller sections applied, here again in order to avoid tape tears primarily by in the roller core 202 in two spaced apart areas Filling inserts 19, 20 with one compared to the material of the Core material low elasticity module are arranged.
- This Execution is of particular interest if for others Band areas than the band edges 15 a targeted, local flatness influencing it is asked for.
