In addition, in the following description, give identical Reference numeral for identical parts.Their title and function are also identical.Thereby, do not repeat detailed explanation about them.
Fig. 1 is the figure of the relevant multiple roll type multi-stage rolling mill 1 of the present invention of expression (following also have the situation that singly is called multi-stage rolling mill), is 12 grades of milling trains.
Multi-stage rolling mill 1 be with homogenous material such as stainless steel or along the thickness of slab direction stacked the rolling equipment that is processed as thin plate such as foil of the stockings such as stacked material 2 of two or more different materials, have the working roll 3 of a pair of configuration up and down.
Each working roll 3 is subjected to 4 supportings of a plurality of (two) intermediate calender rolls, and intermediate calender rolls 4 is positioned at 5 supportings of outermost a plurality of (3) backing roll.In other words, as shown in Figure 1, it is center configuration (multiple roll type) with fan cut as grape cluster that intermediate calender rolls 4 and backing roll 5 have been made with working roll 3,3.In addition, said here outermost is meant and is in apart from working roll 3 position farthest.
Stocking 2 passes through to be rolled on its thickness direction between the above-mentioned a pair of working roll 3,3 towards downstream (right side of Fig. 1) from upstream side (left side of Fig. 1).Go into side and go out side to be respectively equipped with and to be used for guiding smoothly the band guide mechanism 8 of stocking 2 at working roll 3 along rolling bus.
In addition, in the multiple roll type multi-stage rolling mill 1 of present embodiment, possess for working roll 3,3 is gone up in the direction (situation that the Dan Jizuo horizontal direction is also arranged later on) along the rolling direction of stocking 2 and move and make the roller offsetting mechanism 10 of backing roll 5 along continuous straight runs displacement.
As shown in Figure 1, roller offsetting mechanism 10 is equipped on the backing roll 5a.This backing roll 5a is the outermost backing roll that is positioned at the downside of stocking 2, is the roller that is positioned at upstream side along rolling direction.Equally, on the backing roll 5b in downstream, also be equipped with roller offsetting mechanism 10.
Be configured to, so that each roller offsetting mechanism 10 links, make backing roll 5a, 5b to equidirectional displacement by controlling.That is, in Fig. 1, with backing roll 5a, the 5b horizontal shift under the effect of roller offsetting mechanism 10 at "+" expression center.
In Fig. 2, represent to make the roller offsetting mechanism 10 of the backing roll 5a action of upstream side three-dimensionally.Part under the paper left side of Fig. 2 is oblique is the front of this mechanism, is the part that presents among Fig. 1.
As shown in the drawing, backing roll 5a is bearing on the 1st supporting mass 11 via 6 rotations of axle support freely with the form along the 1st supporting mass 11 of strip.The rear side of the 1st supporting mass 11 (with backing roll 5a opposition side) has been made along the inclined plane 12 of the axis direction of backing roll 5a.Separate predetermined distance with this inclined plane 12, be equipped with to form rectangular tabular and be fixed on the 2nd supporting mass 13 on the rolling-mill housing 7.Between the 1st supporting mass 11 (inclined plane 12 of the 1st supporting mass 11) and the 2nd supporting mass 13, the wedge parts 14 that are wedge shape along its length are free to advance or retreat along the axis direction of backing roll 5a.
Drive division 15 advance and retreat that wedge parts 14 are located at its base end side drive, if wedge parts 14 enter (being inserted between the supporting mass 11,13), then open in the gap of the 1st supporting mass 11 and the 2nd supporting mass 13, and then backing roll 5a moves to arrow A side (rolling direction downstream).If wedge parts 14 withdraw from (by extracting) between supporting mass 11,13, the then gap smaller of the 1st supporting mass 11 and the 2nd supporting mass 13, and then backing roll 5a moves to arrow B side (rolling direction upstream side).
In addition,, also can adopt other structures, also the axle support 6 of backing roll 5a, 5b can be constituted with moving horizontally, this support 6 be moved by hydraulic cylinder etc. as roller offsetting mechanism 10.In addition, also can use in the special fair 7-12483 of above-mentioned Japan number, disclose such, be equipped in the roller eccentric (convex surface quantity regulating device) on the backing roll 5.That is, if the offset of the eccentric hoop in making a support 6 (saddle) makes backing roll 5a, 5b rotation after all identical, then backing roll 5a, 5b along continuous straight runs displacement ormal weight.
As shown in Figure 3, if use above-mentioned pair of rolls offsetting mechanism 10 that the backing roll 5a of upstream side and the backing roll 5b in downstream are shifted to equidirectional (for example upstream side), then carry intermediate calender rolls 4 side shifting upstream on outermost backing roll 5a, with its interlock, carry working roll 3 side shifting upstream on intermediate calender rolls 4.This be the position of round unsawn timber of the situation lower and upper that move horizontally with the round unsawn timber that in the round unsawn timber that chevron is piled up, makes lower layer side and its interlock and mobile be identical situation.
The side-play amount of working roll 3, in other words, the amount of moving horizontally of outermost backing roll 5a, 5b is according to the material (being single material or stacked material) of stocking 2, the cross sectional shape (whether being odd-shaped cross section) of stocking 2, lubricated situation etc. and different.For example, be that lower floor extends and the stacked material of the difficult elongation in upper strata easily, multi-stage rolling mill 1 go out side (downstream) upwards under the situation of the such plate bending status of warpage, if the backing roll 5 that many situations make downside upstream lateral deviation move then can access preferred result.
Current disclosed embodiment all is illustration and should not be considered to restrictive aspect all.Scope of the present invention is not by above-mentioned explanation but represented by claims, thinks to comprise the meaning that is equal to claims and all changes in the technical scope.
For example, in embodiment, illustration pair of rolls offsetting mechanism 10 is installed in multi-stage rolling mill 1 on backing roll 5a, the 5b of the lower side that is positioned at stocking 2, but be not limited to this.Also can be configured in than stocking 2 and lean on the backing roll 5 of upper side, backing roll 5c, the 5d along continuous straight runs of note work " x " among Fig. 1 are moved.Also roller offsetting mechanism 10 can be installed in than stocking 2 by backing roll 5a, the 5b of lower side with by on backing roll 5c, the 5d of upper side.
In addition, also can replace note among Fig. 1 to make backing roll 5a, the 5b of "+" and make backing roll 5e (note is made the roller of △) the along continuous straight runs displacement that is not positioned at upstream side or downstream.
As shown in Figure 4, also can in 20 grades, 14 grades, 6 grades multiple roll type multi-stage rolling mill, the roller offsetting mechanism be set and adopt technology of the present invention.In the case, can make centre mark have "+" and/or " * " backing roll along continuous straight runs displacement, make the working roll along continuous straight runs skew of downside and/or upside.
In addition, about with working roll 3 along continuous straight runs of the present invention skew, if be accompanied by some above-below directions (thickness of slab direction) move or the skew of above-below direction also without any problem.
The difficulty that the application of the multi-stage rolling mill that technology of the present invention is not equipped with the multiple roll type to backing roll and working roll (for example backing roll and working roll generally perpendicularly are equipped with milling train) is thought.
, as shown in Figure 5, also can use relevant pair of rolls offsetting mechanism 10 of the present invention, the backing roll 5b that makes the backing roll 5a of upstream side and downstream in the horizontal direction and mutually round about (direction of closing or away from direction) is shifted.
For example, if make outermost backing roll 5a towards the downstream horizontal shift, and make outermost backing roll 5b towards upstream side horizontal shift same amount, intermediate calender rolls 4 side shifting upward then, carry the working roll on the intermediate calender rolls 43 upward (with the direction of the rolling direction approximate vertical of stocking on to upside) move.
On the contrary, if make outermost backing roll 5a towards the upstream side horizontal shift, and make outermost backing roll 5b towards downstream horizontal shift same amount, then intermediate calender rolls 4 moves to the lower side, and the working roll 3 of carrying on intermediate calender rolls 4 moves downwards.
By making pair of rolls offsetting mechanism 10 move horizontally same amount round about simultaneously, working roll 3 knee-actions can be made like this, thickness of slab control can be carried out.
The action of roller offsetting mechanism 10 is that moving up and down preferably of working roll 3 carried out in rolling, but also can carry out before rolling beginning.In addition, the moving horizontally preferably of working roll 3 of utilizing roller offsetting mechanism 10 to carry out carried out before rolling beginning, but also can carry out in rolling.
In addition, roller offsetting mechanism 10 can be installed on backing roll 5a, the 5b, and be installed in the lower side of downside backing roll 5e and/or the upper side of upside backing roll, and can knee-action by making backing roll 5e, also realized the knee-action of the working roll 3 of intention thickness of slab control.
