In the / pressing project, people hope that the steel strip and the metal sheet are flat and unchanged along their length, width and extent, and the required tolerance is also greater.] The use of conventional roller wood is required to be satisfactorily achieved in the middle region, but in the edge region it can lead to unwanted steel strip profiles. The reason for this is that the degree of elastic deformation of the roller is gradually reduced from the area where the load is not affected by the steel. The upper limit starting at the edge of ^ v and the local widening of the steel strip makes the edge of the rolled steel strip thin and sharp, while the thickness of the steel strip is reduced in the edge area (Edge-Drop). Generally, the steel strip is Trimming edges (Besaumen, English: trimming) to remove-part of this uneven thickness of thinned edge area. This work of trimming the edges requires another step of the road guard, and the corresponding cost and an additional part of iron filings. [Prior art] In the white-know technology, 'the methods of reducing the thickness of the edge near the edge of the rolled steel strip in the European Patent Ep 0153 849 131 and EP 0 8 113 B1 are mentioned. The principle of back grinding (㈣kschliff, English: backgrind) at different levels of the cone is used to make different parts. Using this linear post-grinding action, the diameter of the working roller can only be changed linearly in 200306236. The overall profile of the roller body (Bal len) is not continuous, so the roller body cannot be ground at one time, but the transition zone between the roller body and the back grinding part must be interrupted. EP 0 488 367 B1 discloses a method for adjusting the reduction of the edge thickness when cold milk finemouthed v Hui and steel. One of the working rollers with a tapered end at one end moves axially on the exit side according to the measured value. . The deviation between the edge reduction and the final nominal edge reduction is determined based on the width measured by the steel at the entrance side, and the deviation is input to adjust the axial movement. In addition, in Ε " 876 857 B1, it is mentioned that in the case of a tapered and narrow roller at one end, a traditional W grinding section is overlapped to make this interference side effect on the rolling gap area F ^ 1 This uses special CVC rollers as working rollers, and Zhifan farmers use the off-line calculation operation to determine the convexity (Cr 嶋) of the towel corresponding to the moving object of the roller. But in this conventional concept, especially in fine grinding and surface treatment = in terms of: the production of the work roller is more complicated, and the rolling result is only satisfactory.

Accuracy. This purpose is achieved in accordance with the present invention, so that each working roller provided in the roller frame can be moved in the axial direction. ^ ^ ^ ^ A /, at least one of the end regions of the working roller has Continuous non-linear roller profile. 200306236 The focus of the present invention is: the change in the diameter of the roller body (in the conventional rolling device, this change is tapered, or linearly changes along the longitudinal section) on the one hand when manufacturing work rollers Will increase the cost, on the other hand, its accuracy is limited when the strip profile is controlled and adjusted in the edge area of the strip. In particular, the transition from the generally cylindrical roller body to its tapered end region is a sudden transition (abrupt change), and this transition effect is especially during fine grinding of the roller body Processing needs to be interrupted. Therefore, in order to avoid this point d, the transition from the generally cylindrical region of the roller body to the narrower and narrower area of the roller body must be adjusted to be particularly smooth, rather than making the diameter along the longitudinal section approximately linear. This reduction is achieved by making the roller contour of the end region of each working roller constant, but non-linear. In the advantageous advantageous step feature of the present invention, the contour of the end region of each working roller is designed such that when the roller body is operated, its constant non-linear roller contour can just compensate the deformation of the roller body. In this way, a substantially continuous flat interface can be caused in the area where the rolled object is in contact with, so that its deformation in the end zone of the steel strip can be kept particularly small. Regarding the contour design of the roller body, regarding the deformation of the roller body, especially the experience that has been made earlier should be considered. For this reason, the non-linear roller profile of the narrowing and narrowing area of each work and fader is determined based on the representative measurement value or characteristic value of the roller body by a relevant calculation program for determination. When using a large number of such narrow working rollers, the continuous non-linear roller profile of one of the working rollers should be coordinated with each other; the roller profile setting of the roller should be set. Designing the end area of the working roller to match the wheel waste design ’can provide excellent accuracy when manufacturing 200306236 rollers. In order to make use of this in a particularly effective way so that the thickness of the rolled house can maintain a special value even in the edge area, the rolling house device should include an adjustment device, which is based on the steel tested. With the measured value of the thickness, an adjustment value is output to position each working roller in the longitudinal direction. In this way, it can be ensured that according to the thickness trend of the rolling house object actually obtained, the thickness of the edge area can be compensated by positioning the narrow and narrow satellite roller along its longitudinal axis. Tian Ye The working roller should be able to move in the pumping direction in a way that allows us to change the profile of the strip at the edge ^ depending on the type of dust ’s strip width and / or strip thickness. The advantages achieved by the edge region using the present invention are particularly: the continuous non-linear contour design of the end region of each body can produce-a kind of continuous = sub-contour, 胄 # the deformation properties of the working roller during the rolling process Washing rolls can be fully compensated. Especially in the use of advanced roller grinding technology 5, ^ The roller body of this tapered working roller can be ground in a single pass (may include one edge after grinding) for grinding, where the nominal contour d The package outline s is calculated by the operator, and is based on the deformability of each working roller: based on) can be specially designed to make the transition zone between the contact area and the area of the working roller relatively smooth. A, Tian Zazi A detailed description of an embodiment of the present invention will be described with reference to the drawings.

An associated support roller or intermediate roller or (10) support is available. The rolling device (1) is designed to manufacture rolled objects (6), which have a particularly flat and uniform steel strip profile even in their edge regions. There is a design goal here, which is to avoid rolling as much as possible. The thickness of the steel strip (6) in its edge area is continuously reduced by the influence of the load. In order to achieve this goal, the profile of the working roller in one end area is continuously narrowed. The roller profile of each working roller (2) or (4) is designed so that the roller diameter decreases continuously and non-linearly until the end of each roller 200306236 (12) or (14). Here, the contours of the working rollers (2) and (4) are selected so that the thickness of the steel strip in the processed article is similar and constant even in the end region. The deformation effect caused by rolling force can be compensated. Here, the design of the wheel temple of the working roller is determined by taking into account an appropriate calculation formula and using a roughly cylindrically designed working roller based on empirical values. The working roller (2) ⑷ is designed to be movable in the axial direction (that is, along its center axis and rotation axis indicated by dashed lines (16) or (18)). In this way, the working rollers (2) ⑷ can be positioned relative to each other in the axial direction, so that the thickness deviation of the 钿 area of the roller ⑻ can be adjusted by appropriately adjusting the contoured end regions of each working roller. Need to be determined and compensated in accordance with each situation. In order to achieve this in a particularly simple and automated way, there is an adjustment device (cooperating with the rolling device), the adjustment device (2) is based on the measured An adjustment value is output according to a characteristic value of the thickness of the rolled object ⑻, so that ^ work; 衮 子 (2) 定位 is positioned along its longitudinal direction. As shown by the arrow (22), this setting (4G) is used to connect with most sensors located in the area near the rollers to determine the thickness of the steel strips.
