Abstract

A cold rolling mill has groups of paired working rollers (10) with supporting rollers (12), followed by six pairs of roller frames with intermediate rollers (11). The working rollers and intermediate rollers have limited axial sliding freedom. The cold rolling mill combines CVC/CVC(plus technology, Per Cross Technology, and the use of strip edge-orientated axial slip of the working and intermediate rollers. The CVC/CVC(plus technology employs CVC roller contours, in which each working roller or intermediate roller has an extension that embraces the side shift zone. The Per Cross technology facilitates azimuth swivel movement of the working and intermediate rollers parallel to the plane through which the strip advances. The strip edge-orientated axial slip of the working and intermediate rollers facilitates equal and opposite shift of these rollers relative to a neutral position.

The wheel and the device for axial displacement [prior art] In the past, for the thickness of the cold milk plate: thickness, plate The off-chip type of porch, the flatness of the slab, and the surface J are the most straightforward. In terms of material quality and geometrical dimensions, the product diversity of cold enamel metal on the market has also led to a gradual increase in production: Scope. This trend has been introduced _ light oblique slamming day of mouth 1 machine operation mode of the gradual system: design and about tandem (four) rolling products., increasing the best - not the most suitable for the last four The traditional system design of the machine, including the number of stands required to continuously configure several flats and rafts, is basically determined by the overall control to be achieved.兀1' curved system and fixed In addition to the basic concept of the curvature of the wheel, 2 different principles of action 'there are basically three other frame designs that affect the roller gap by the offset or tilt of the work wheel. s Hai and other designs are: plate edge, Edge orientation deflection technology m 6 • cvc-cvcplus technology • PC technology (perCross – tilting of the work wheel) Due to different technical standards, the deviation from the traditional system design (uniquely including 4 roller bases) and the design of the independent stand 6 Roller stands may be useful. In particular, in the case of higher strength levels, the implementation of a desired final thickness and the implementation of certain reduced distributions (by straight line design) are significantly affected by the diameter of the working roller. The effect is that when the diameter of the working roller is reduced, the required rolling force is also reduced because of the more favorable flattening behavior. The reduction of the diameter is limited by the transmission of the rotational moment and the deflection of the roller. If the profile of the journal is insufficient to transmit the drive torque, the work roller can be driven by the adjacent roller via the frictional contact. In the case of a four-roller base, heavy drive elements (motors, pinion drives, spindles) are required to drive the roller, making the system more expensive. In this case, each will be different. It is useful to use a six-roller base that is not equipped with a driving device with an intermediate roller. The vertical deflection and horizontal deflection of the working roller and the intermediate roller affect the board. The key factor of the flatness of the piece. The horizontal displacement at the center of the heart or the center of the heart is used to support the wheel set, thereby significantly reducing the horizontal deflection. (4) (4) Working it round ' Μ The order in the flatness and the roller door gap will be affected by the advance step, such as the Japanese patent 190 7°4Α for the four-roller frame. The 'each work roller or the intermediate roller will be located in parallel [S1 7 1324093 The common pivot point in the roll-to-spindle of the plane of the slab is inclined by the same amount toward each other. In addition, the six-wheel stand has an additional quick control element in the middle roller deflection. Together with the deflection of the working roller, the six roller housing has two control elements that are independent of the action on the roller gap. This will ensure that the roller gap can be quickly adapted to the slab profile rim entering the first frame to prevent flatness deflection. In the final frame, two control elements can be effectively used to adjust the flatness. Another criterion for the quality of the final product is the surface condition of the output sheet. The surface of the plate can be preset in a targeted manner via a roller having a specific structure (roughed) and being recorded. In order to prevent the transfer of the worn edges from causing traces on the final product or the difference in the relative speed across the entire width of the sheet creating a shadow on the surface of the sheet, it is advantageous to have the last stand of the tandem cold machine. The frame is configured as a six-roller. The special working roller is cylindrical or slightly raised. They do not shift during the spin-dry process. Due to the need for different roller geometries, the principles described in the previous section relate to individual stand designs. In the traditional cvc technology, as described in __ (4), the cylinder of the displaceable roller is always longer than the non-movable roller—the axial displacement of the roller can not be fixed. 2 under the roller cylinder. This prevents the surface from being damaged, leaving the trace roller to be supported by the middle or the support roller over its entire length. The rolling force exerted by the roller is transmitted to the entire working wheel. 1320403 === The ends of the work rolls that protrude laterally above the rolled material and therefore do not and are subjected to the rolling operation are deflected toward the rolling material by the applied force. The rolling section of the center of the rolling center is sufficiently rolled up by the upward bias, and the sheet area = the central sheet area is not rolled and the edge of the sheet is significantly rolled. These effects are particularly pronounced in the case of changing the roll during operation, ^, vi*; ... or when the width of the rolled sheet is different. Conversely, in the technique of directional displacement of the edge of the slab, the DE 22 06 912 C3 furnace and Hk four are used in the entire set of rollers. Here, 滚轮', one of the two in the edge region of the cylinder: the displacement of the roller system is designed with a corresponding geometry on the side of the T, and consumes the area to reduce the peak load that occurs locally. The principle of this action is based on the orientational displacement of the edge of the panel at the front, top, and edge of the edge of the panel. In particular, the displacement of the inter-roller under the support roller on the side of the six-wheel carriage means that the effect of the positive displacement of the work roller is affected in a targeted manner. However, in this method, the axial displacement of the rollers is detrimental to the load distribution in the various contact joints. When the thickness of the sheet is reduced, the distribution of the contact force is large, and the load peak value is significantly increased. The German patent application DE 36 24 241 C2 (Poetry Operation (4) Machine for Shame Rolling Plates) describes the mixing of the two methods. The purpose of the method is to stabilize the unfavorable deflection of the work roller under the influence of the rolling force over the entire width of the plate, and to increase the displacement distance to increase the effect of the roller deformation system without interruption The operation of the continuous rolling of the breast 1324093 is achieved by displacing the displacement of the edge of the sheet in the middle of a applied CVC wear zone and the working wheel. The cylindrical edges of the cvc rollers are positioned in the edge regions of the sheets. When the technique of directional displacement by the edge of the slab is used, the set of rollers includes rollers having the same length of the drum. For economic reasons, in order to reduce the cost of maintaining and replacing parts, each stand is strived to be designed to be the same. As a result, the rate trainer was previously designed to have a conventional system configuration or to use the described techniques in all aspects. SUMMARY OF THE INVENTION It is an object of the present invention to implement these techniques/operation modes via a stand design of a roller set having the same geometry, and the set of rollers is not limited to only six roller stands and intermediate rollers. According to this method, this object is achieved by the combination of the following features in the multi-stand tandem cold rolling mill technology by using the features of the scope of the patent application: • Using cvc/ with a higher level of CVC roller profile Cvcplus technology, each work roller or intermediate roller has a roller extended by the displacement stroke; • Using Per Cross (PC) technology, each work roller or intermediate roller can be rotated parallel to the plane of the plate; The edge of the sheet of the working roller or the intermediate roller is oriented displaced, each working roller or intermediate roller having a roller that is extended by the displacement stroke and comprising a cylindrical or raised wear region, and which is relative to the center of the housing The neutral displacement positions are symmetrically displaced toward each other by the same distance toward [S1 10 1324093 in the direction of the rotating main shaft. A system for carrying out the method is characterized by the features of item 5 of the scope of the patent application. The roller structure from the cVC/CVCplus technology is used as the base for the design of the six-roller or four-roller frame. The displaceable intermediate or working roller has a roller that is extended by the CVC displacement stroke and is symmetrically seated in the center of the housing for the neutral displacement position. The working roller or intermediate roller having a long and symmetrical cylinder is used in a cylindrical or raised wear zone during the blade edge guiding displacement process. The proper design of the wear zone in the edge region of the cylinder, together with the optimization of the width of the overlapping wear roller and the axial displacement position, allows the deformation behavior of the roller set and the deflection of the positive working roller (, The effect of the roller base is affected in a targeted manner and the gap of the roller can be optimally set. In addition, the roller area within the roller set is flowed from the force by means of the position of the working roller or the intermediate roller in a targeted manner: shape = reach: ideal seat principle, when, when In the negative direction, the load distribution occurring at each connection point increases due to the shorter contact length. Gap: The design of the base is modified in accordance with the present invention to effect displacement or tilting of the roller or intermediate roller. When another -, the falling control element is to be implemented in the frame _, in the case of a six-wheel stand is absolutely important two - for the contour and (four) for this purpose, two d - The degree of independent displacement system is a must. The system name configuration is mainly based on the requirements of the women's placement in the rolling process. The system configuration range is from the traditional tandem cold-rolling six-roller base including the four-wheeled machine base. 'Combination system and only six-wheel stand tandem cold rolling mill. For the implementation of the blade edge orientation 〇〇 4Al in a six-roller turret that does not include an intermediate roller and that is used exclusively in a roller set of the same shape, as described in German Patent DE 100 37 [Embodiment] Figures 1 and 2 show the geometry of the working roller or intermediate roller 11 in the area of the wear roller. 4, in Figure 1, the displaceable intermediate roller η with an elongated cylinder is symmetrically placed in the center γ_γ of the machine base and is seated in the turret roller ig and branch (4) in the vacant two-shift position Szw=G Take the round. In Fig. 2, the working roller 10 has an elongated roller. The working roller is also symmetrically placed in the C γ·γ in the frame and is seated in the neutral displacement position Saw^O. FIG. 3 is a single side wear area u a working roller or door; the wheel 1 1 A schematic view of the appearance and geometrical configuration in the edge region of the cylinder. The patent DE10〇37_Al has included a detailed description and a diagram of a single side wear region as used herein. * The length of the single side wear region d in the cylindrical edge region of the working roller 10 or the intermediate roller i is divided into two adjacent regions a, b. In the first region a, the wear region d is a pattern (1-X) + y-R' that conforms to a circle from the point d〇, and R is a radius of the wheel. A size d(x) of the wear region d can be obtained from the region a: Γ Γ - 1 10 1 12 1324093 Region a = (R2_(R_d) 2) 1/2 - d = d (x) = R - (R2_( I_x)2)i/2 If a specified minimum required diameter reduction of 2d depending on external edge conditions (rolling force and resulting roller deformation) is achieved, the wear region d will linearly extend to the edge of the cylinder, Region b will be generated: region b = la - d = d (x) = conversion between constant regions a and b can be designed by or without continuous differential transformation. The transformation of this wear zone can also be produced via a continuous reduction d of the dimensions resulting from the flattening effect according to previously set charts. For example, the wear zone d is thus more flat than the radius in the transition zone and steeper at the end. Due to the reasons associated with the grinding technique, the transition to the cylindrical portion must be designed by a relatively large step in the transition between a and b (about 2d). The reduction in diameter is determined by the wear zone so that the work roller 10 in a six roller carriage can freely deflect the amount of wear zone d of the intermediate roller raft without the risk of contact areas. In the four-wheel stand, the function of the wear zone d is only to reduce the peak load that occurs locally. Generally speaking, as shown in FIG. 4 and FIG. 5, the wear area of the single side is located on the working side bs" of the upper work roller 10 or the intermediate roller n and the lower working roller Η) or the intermediate roller u Drive the side of the heart. If the upper working roller 10 or the wear area of the "_ U is "skin" on the driving side AS and the lower working rolling age, the grinding wheel 10 or the middle roller 11 is positioned at work. On the side BS, the principle of the action of Putian does not change.

In Fig. 6a, the starting point of the wear region is located on the outer edge of the edge of the plate 13 ^ 4093 (m = +); in Figure 6b, the starting point d is located on the plate On the edge (m = 0); in Figure 6c 'the starting point d is located inside the edge of the sheet (m = -)', that is, already within the width of the sheet. The positioning occurs depending on the width of the sheet and the nature of the material. It is possible to adjust the elastic behavior of the roller set and the tilt of the forward working roller (six-wheel stand) in a targeted manner. Finally, Figures 7a to 7c show the edge displacement of the blade edge of the working roller 1〇 in the same manner as the intermediate roller 11 in Figures 6a to 6e. In different plate width regions, the displacement position is determined by an incremental linear step function, where the area is based on the different positions of the starting point d〇 of the wear region d relative to the edge of the sheet. A significant advantage of the described stand design is that both the cvc/cvcplus technology and the edge orientation of the plate can be implemented using a single, geometrically shaped set of rollers. Different wheel types are no longer needed. The only difference is the area of the wear roller used or the area of wear according to the specifications specified above. This also provides the ability to combine the two techniques with the tilt of the work or intermediate rollers in the plane of the slab.
