Description
The present invention relates to the method that a kind of method of operation that makes each rolling support in the lap siding cold-rolling mill combines, in 4 rolling system supports, respectively comprise a pair of working roll and backing roll, and subsidiaryly in 6 rolling system supports also have a pair of intermediate calender rolls, wherein working roll and intermediate calender rolls and be used for axially movable device acting in conjunction at least.
The quality requirement about thickness of slab tolerance, accessible final thickness, strip profile, band flatness and surface or the like aspect of past for cold rolling strap improving always.The diversity of product also causes having produced the more and more multiple various relevant material property and the product line of physical dimension aspect on the cold-reduced sheet market.Because making in the lap siding cold-rolling mill, this development becomes more and more stronger according to the hope of the equipment design and the method for operation (being matched with the rolling final products of wanting best) more flexibly.
Traditional equipment design of lap siding cold-rolling mill is that a plurality of 4 rolling system supports are connected to each other.Required support quantity is mainly determined by the whole drafts and the final thickness that will reach.Except the basic design scheme of roll crown of using bending system and fixing as the adjustment means of intervening roll gap, mainly also have other three kinds of rolling support schemes, they or moving or additionally intervene roll gap based on different action principles by working roll by swing.
These are:
● with the technology that moves of belt edge orientation
● CVC/CVC
+-technology
● PC-technology (Per Cross (by intersecting)--working roll swing)
Because different process criterias may reasonably be: be different from traditional equipment design (including only 4 rolling system supports) and each rolling support is made 6 rolling system supports.
The drafts that reaches desirable final thickness and realize determining distributes (rolling shedule design), especially is subjected to the influence of work roll diameter when the fine and close quality of height to a great extent.Along with work roll diameter reduce reduce owing to more favourable pressing performance makes required roll-force.The reducing of diameter considers still that from the transmission of torque the bending of roll all has qualification.If the roll neck cross section is fewer than the transmission driving torque, working roll can and be driven by adjacent rollers by the friction connection so.If a kind of 4 rolling system supports must have heavy driving element (motor, double helical gearing, axle) to be used to realize that backing roll drives certainly, these elements make the expense of equipment become expensive.Reasonably single rolling support (majority is the front) is designed to have 6 rolling system supports of intermediate calender rolls driving mechanism in addition.
Except vertical bending, the horizontal curvature of working roll and intermediate calender rolls also plays an important role for the flatness of band.With the supporting that has realized complete roll that moves horizontally in the rolling support mid-plane, this reduces horizontal curvature greatly by working roll/intermediate calender rolls.
The additional influence of the operation of rolling is the swing of working roll about flatness and roll gap aspect, wherein as among JP 57 190 704 A for described the 4 rolling system supports, working roll/intermediate calender rolls is parallel to the band plane around common point of rotation and respectively swings identical amount mutually simultaneously in the middle of roll shaft.
This external intermediate calender rolls of 6 rolling system supports also has an additional member of adjustment fast when crooked.Combine with working roller bending, this 6 rolling system support just has two and independently adjusting member aspect the roll gap effect.Therefore guaranteed in the first rolling support that roll gap adapts to the strip profile section that enters apace to avoid the defective of flatness.In last rolling support, can in the planarity adjustment system, use two adjustment means effectively.
Another criterion of end product quality is the surface characteristic of outlet band.Because the systematism of roll processing (hacking) and chromium plating can advantageously preestablish the surface of band.For fear of moving or, reasonably be that the last rolling support with the lap siding cold-rolling mill is designed to 6 rolling system supports on the final products because wearing and tearing limit covering owing to exporting on the width of band and the mark that relative speed difference causes occurs on the belt surface.Working roll is columniform or little convexity is arranged.They do not move in the operation of rolling.
For above-mentioned action principle, be meant rolling support scheme separately, because need different roll geometries.In traditional CVC-technology, described in EP 0 049 798B1, the barrel length of removable roll always will grow than roll fixing, that do not move and axially shift out stroke as it.Therefore just can making movably, roll is not to move under fixing roll barrel with its body of roll edge.Therefore avoided surface damage/formation sign.Working roll generally all is supported on intermediate calender rolls or the backing roll on its whole length.So just the roll-force that is applied by backing roll is delivered on the whole length of working roll.This has caused: the side protrude in rolled parts and the working roll end that therefore in the operation of rolling, do not participate in since act on above it roll-force and on the direction of rolled parts, produce crooked.Because this infringement bending of working roll has caused the bending of roll intermediate section.It has caused that the centre of band is very little rolling and belt edge is all rolling strongly.This effect especially is suitable for when when work, rolling condition changed and during the band at rolling different in width.
By comparison, in the directed technology that moves, as disclosed in DE 22 06 912 C3, in whole complete roll, used roll with identical barrel length with belt edge.Removable roll one side makes corresponding geometry and an anti-mill district is arranged in body of roll edge, in order to reduce the local load peaks that occurs.Action principle based on body of roll edge with replenish the moving of belt edge orientation, perhaps before belt edge, on or even until after the belt edge.Especially intermediate calender rolls moves to the validity that has just caused under the backing roll for positive working roller bending and produces favorable influence when 6 rolling system supports.Certainly in this method, moving axially for the load in contact seam separately of roll distribute to produce disadvantageous effect.Along with diminishing of bandwidth, the load peaks that the maximum that contact force distributes occurs just increases greatly.
(being used to drive the method that band is rolled in the milling train manufacturing) in patent specification DE 36 24 241 C2 mutually combines two kinds of methods.Purpose is: make working roll disadvantageous bending under the roll-force effect on whole bandwidth series evenly, and under the situation that shortens shift motion, strengthen the validity of roll bending system, and needn't interrupt continuous rolling operation.This target is added with the intermediate calender rolls of CVC-grinding or reaching with moving of belt edge orientation of working roll by having one.The body of roll edge of CVC roll is positioned in the belt edge position.As when the technology that moves of belt edge orientation, complete roll is made up of the roller of identical barrel length.
Owing to the economy reason, it is identical that people make every effort to that all rolling supports are made, so that reduce the expense of maintenance and spare part.Therefore the lap siding cold-rolling mill just designs or designs by described technology without exception by traditional equipment in the past.
Task of the present invention is to realize this technology/move mode by the rolling support scheme with the identical complete roll of geometry, and this complete roll is not restricted to 6 rolling system supports, and is not restricted to intermediate calender rolls.
Being proposed of task, solves by use following technology in combination in the lap siding cold-rolling mill of multimachine seat by the described characteristic features of claim 1 according to method:
● use the CVC/CVC of the rolling profile of CVC with higher level
+Technology, wherein each working roll/intermediate calender rolls has a body of roll that prolongs shift motion;
● by intersecting (PC) technology, wherein each working roll/intermediate calender rolls can be parallel to the band plane rocking;
● use the moving with the belt edge orientation of working roll/intermediate calender rolls, wherein each working roll/intermediate calender rolls has the body of roll of the shift motion that extended, the body of roll has cylindrical or spherical grinding area, and make they with respect to the shift position of neutrality in the middle of rolling support symmetrically on its rotation direction mutually separately mobile phase with amount.
The equipment that is used to implement this method is characterised in that the described feature of claim 5.
As the basis of rolling support scheme, for 6 rolling system supports or 4 rolling system supports, used CVC/CVC
+Roll configuration in the technology.Movably intermediate calender rolls or working roll have one and add the body of roll that grows the CVC shift motion, and it is symmetrically located in the middle of the rolling support for the shift position of neutrality.
Working roll/intermediate calender rolls with long symmetrical body of roll is used with belt edge orientation mobile the time, the body of roll or have a kind of columniform or spherical grinding area.By compatibly implementing a kind of anti-mill in body of roll edge, in conjunction with overlapping roller grinding area with depend on bandwidth the optimization that moves axially the position can be advantageously exerted one's influence and set up roll gap best the validity of complete roll deformation performance and positive working roller bending (6 rolling system support).
In addition, the optimization of the shift position by working roll/intermediate calender rolls advantageously makes body of roll position withdraw from power stream within the complete roll.The distortion that plays negative interaction that draws thus has been reduced, because near the principle of " desirable rolling support ".Certainly since contact length reduce distribute and improved contacting the load that occurs in the seam separately.
Described rolling support scheme is made amendment like this according to the present invention, makes or moving or influence roll gap by swing by working roll/intermediate calender rolls.A kind of 6 rolling system supports are to force essentially in each case, will insert a kind of adjustment means of the subsidiary edge penalty that influences band (Edge Drop) this moment in rolling support.For this reason must two separate mobile systems that are used for profile and flatness.The equipment configuration is mainly determined by these criterions.Depend on the requirement that is proposed, the combination of the various equipment configuration of traditional lap siding cold-rolling mill that comprises 4 rolling system supports by equipment, comprise that 4/6 rolling system support is once much of that until a lap siding cold-rolling mill of being made up of 6 rolling system supports the operation of rolling.Use under the situation of the identical complete roll of a kind of geometry,, be used for realizing having done detailed description at DE 100 37 004 A1 with the basic skills of the shift strategy of belt edge orientation except intermediate calender rolls and except in 6 rolling system supports.
Other advantage of the present invention, details and feature are visible following to some explanations that embodiment did shown in simple and clear in the accompanying drawings.For the sake of clarity identical roll adopts identical Reference numeral.
Accompanying drawing is depicted as:
Fig. 1: the geometry that in one 6 rolling system support, does not have the intermediate calender rolls of roll dressing;
Fig. 2: the geometry that in one 4 rolling system support, does not have the working roll of roll dressing;

In Fig. 1 and 2, represented not have the geometry of the intermediate calender rolls/ working roll 11,10 of roll dressing.The removable intermediate calender rolls 11 of the body of roll that in Fig. 1, is provided with lengthening between working roll 10 and backing roll 12 at the shift position of neutrality s
ZWBe symmetrically located at rolling support center Y-Y on=0.Working roll 10 has the body of roll of lengthening in Fig. 2.It is also at the shift position of neutrality s
AWBe symmetrically located at rolling support center Y-Y on=0.
Profile and the geometry of one-sided anti-mill amount d in the body of roll edge of working roll/ intermediate calender rolls 10,11 represented in summary in Fig. 3.In DE 100 37 004 A1, described a kind of one-sided anti-mill district in detail, as it is applied herein, and be shown in the accompanying drawing.
The length l of one-sided stock removal d is divided into two position a and b that are close to mutually in the body of roll edge of working roll/intermediate calender rolls 10,11.In the first position a of inside, at d
0The beginning of some place, anti-mill amount d is according to equation of a circle (l-x)
2+ Y
2=R
2, R is a roller radius.The amount d (x) that draws anti-mill d for a of position is:
Position a:=(R
2-(R-d)
2)
1/2 d=d (x)=R-(R
2-(l-x)
2)
1/2
Reduce 2d if reached a minimum essential diameter that depends on the regulation of external boundary condition (roll-force and consequent roll deformation), so anti-mill amount d is linear to be extended until body of roll edge, draws for the b of position thus.
Position b:=l-a d=d (x)=constant
Transition between position a and b can make the changeover portion that has or all do not have continuously differentiable to divide.Anti-in addition this transition of grinding also can be carried out the order feedback with this size d that is obtained by the pressing amount according to a form of being tried to achieve in the past and obtain.So anti-mill amount d is for example milder than radius in transition region, and is much then steep in the end.Be located to the transition portion of column part owing to the reason of grinding technique aspect (approximately 2d) on the corresponding bigger step of transition portion between a and the b.
Stipulate like this to reduce 2d, make the anti-mill amount d that in a kind of 6 rolling system supports working roll 10 can freely crooked intermediate calender rolls 11, and needn't worry in the b position, contact is arranged owing to the diameter that anti-mill causes.Anti-mill amount d only is used for the local load peaks that is occurred that reduces in 4 rolling system supports.
Under normal circumstances the one-sided anti-mill amount d on top working roll/ intermediate calender rolls 10,11 is positioned at and handles side BS, drives side AS and then be positioned on bottom working roll/ intermediate calender rolls 10,11, shown in Figure 4 and 5.If anti-mill amount d is set on the contrary, on top working roll/ intermediate calender rolls 10,11, be positioned at driving side AS, handle side BS and on bottom working roll/ intermediate calender rolls 10,11, then be positioned at, action principle there is no change so.
Represented that in Fig. 6 a to 6c intermediate calender rolls 11 moves axially a shift motion m.The beginning d of anti-mill amount d in Fig. 6 a
0Be positioned (m=+) beyond the belt edge, in Fig. 6 b, be positioned (m=0) on the belt edge, and in Fig. 6 c, be positioned belt edge, that is to say within bandwidth with interior (m=-).Depend on that bandwidth and material property position, therefore can on purpose set the validity of the elastic performance of complete roll and positive working roller bending (6 rolling system support).
In Fig. 7 a to 7c, represented at last with moving with the belt edge orientation as the working roll of in Fig. 6 a to 6c, intermediate calender rolls 11 identical modes being implemented 10.
Stipulate by piece-wise linear membership function (Ansatz-funktion) that in different bandwidth ranges they are based upon the beginning d of anti-mill district d
0On the basis with respect to the diverse location of belt edge.
The major advantage of described rolling support scheme is: only just can realize CVC/CVC with the identical complete roll of a kind of geometry
+Technology and with the moving process of belt edge orientation.No longer needed different roll types.Difference only also is according to the added roll dressing of the setting value that forms above or anti-mill.Can also with the swing of working roll/intermediate calender rolls in the band plane two kinds of technologies be mutually combined by way of parenthesis simultaneously.
