Fig. 1 is the figure representing about multiple roll type multi-stage rolling mill 1 of the present invention (also having below the situation that is singly called multi-stage rolling mill), is 12 grades of milling trains.
Multi-stage rolling mill 1 be by the homogenous materials such as stainless steel or along thickness of slab direction stacked stocking 2 rollings such as stacked material of two or more different materials be processed as the equipment of the thin plates such as foil, there is the working roll 3 of upper and lower a pair of configuration.
Each working roll 3 is supported by multiple (two) intermediate calender rolls 4, and intermediate calender rolls 4 is positioned at outermost multiple (3) backing roll 5 and supports.In other words, as shown in Figure 1, intermediate calender rolls 4 and backing roll 5 have been made the configuration with fan cut (multiple roll type) as grape cluster centered by working roll 3,3.In addition, said outermost refers in apart from working roll 3 position farthest here.
Stocking 2 passes through, between above-mentioned a pair of working roll 3,3, on its thickness direction, to be rolled towards downstream (right side of Fig. 1) from upstream side (left side of Fig. 1).Enter side and go out side to be respectively equipped with the band guide mechanism 8 for guide smoothly stocking 2 along rolling bus at working roll 3.
In addition, in the multiple roll type multi-stage rolling mill 1 of present embodiment, possesses the roller offsetting mechanism 10 that makes backing roll 5 along continuous straight runs displacements in order to make upper movement of working roll 3,3 directions in the rolling direction along stocking 2 (also having the situation that is singly denoted as horizontal direction) later.
As shown in Figure 1, roller offsetting mechanism 10 is equipped on 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, be also 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.,, in Fig. 1, represent backing roll 5a, the 5b horizontal shift under the effect of roller offsetting mechanism 10 at center with "+".
In Fig. 2, three-dimensionally represent the roller offsetting mechanism 10 of the backing roll 5a action that makes upstream side.The front of the left part Shi Gai mechanism under tiltedly of the paper of Fig. 2 is the part presenting in Fig. 1.
As shown in the drawing, backing roll 5a rotates and is bearing in freely on the 1st supporting mass 11 via axle support 6 with the form of the 1st supporting mass 11 along strip.The rear side (with backing roll 5a opposition side) of the 1st supporting mass 11 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 and be formed as rectangular tabular and be fixed on the 2nd supporting mass 13 in 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 along its length wedge shape 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 supporting mass 11,13), open in the gap of the 1st supporting mass 11 and the 2nd supporting mass 13, and then backing roll 5a is mobile to arrow A side (rolling direction downstream).If wedge parts 14 exit (by extracting between supporting mass 11,13), the gap smaller of the 1st supporting mass 11 and the 2nd supporting mass 13, and then backing roll 5a is mobile to arrow B side (rolling direction upstream side).
In addition, as roller offsetting mechanism 10, also can adopt other structures, also the axle support 6 of backing roll 5a, 5b can be formed with moving horizontally, by hydraulic cylinder etc., this axle support 6 be moved.In addition, also can use in No. 7-12483, above-mentioned Japanese Patent Publication, disclose such, be equipped in the roller eccentric (convex surface quantity regulating device) on backing roll 5.That is, if make backing roll 5a, 5b rotation after the offset that makes the eccentric hoop in axle support 6 (saddle) is all identical, 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 for example, are shifted to equidirectional (upstream side), carry the upstream side shifting of intermediate calender rolls 4 on outermost backing roll 5a, with its interlock, carry the upstream side shifting of working roll 3 on intermediate calender rolls 4.This is that movement is identical situation with making the position of round unsawn timber of the situation lower and upper that the round unsawn timber of lower layer side moves horizontally and its interlock in the round unsawn timber of piling up in chevron.
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 cross sectional shape (whether being odd-shaped cross section), the lubricated situation etc. of the material of stocking 2 (being single material or stacked material), stocking 2 and different.For example, that lower floor easily extends and the difficult stacked material extending in upper strata, in going out the upturned such plate bending status of side (downstream) of multi-stage rolling mill 1, if the backing roll 5 that many situations make downside upstream lateral deviation move; could obtain preferred result.
Current disclosed embodiment is all to illustrate and should not be considered to restrictive aspect all.Scope of the present invention is not by above-mentioned explanation but is represented by claims, thinks and comprises all changes in meaning and the technical scope being equal to claims.
For example, in embodiment, exemplified with the multi-stage rolling mill 1 pair of rolls offsetting mechanism 10 being arranged 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, make to be denoted as in Fig. 1 the backing roll 5c of " x ", 5d along continuous straight runs to move.Also roller offsetting mechanism 10 can be arranged on than stocking 2 on the lower side backing roll 5a, 5b and by backing roll 5c, the 5d of upper side.
In addition, also can replace the backing roll 5a, the 5b that are denoted as "+" in Fig. 1 and make not to be positioned at backing roll 5e (being denoted as the roller of △) the along continuous straight runs displacement in upstream side or downstream.
As shown in Figure 4, also can in the multiple roll type multi-stage rolling mill of 20 grades, 14 grades, 6 grades, roller offsetting mechanism be set and adopt technology of the present invention.In the case, can make have the backing roll along continuous straight runs of "+" and/or "×" to be shifted, to make the working roll along continuous straight runs skew of downside and/or upside in centre mark.
In addition, about by working roll of the present invention 3 along continuous straight runs skews, if be accompanied by the movement of some above-below directions (thickness of slab direction) or the skew of above-below direction also without any problem.
It is more difficult that the application of the multi-stage rolling mill (milling train that for example backing roll and working roll are generally perpendicularly equipped with) that technology of the present invention is not equipped with multiple roll type to backing roll and working roll is thought.
, as shown in Figure 5, also can use relevant pair of rolls offsetting mechanism 10 of the present invention, make the backing roll 5a of upstream side and the backing roll 5b in downstream in the horizontal direction and mutually round about (direction of closing or away from direction) be shifted.
For example, if make outermost backing roll 5a towards downstream horizontal shift, and make outermost backing roll 5b towards upstream side horizontal shift same amount, intermediate calender rolls 4 side shifting upward, carry working roll 3 on intermediate calender rolls 4 upward (in the direction substantially vertical with the rolling direction of stocking to upside) mobile.
On the contrary, if make outermost backing roll 5a towards upstream side horizontal shift, and make outermost backing roll 5b towards downstream horizontal shift same amount, 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 round about same amount, can make working roll 3 knee-actions like this, can carry out thickness of slab control simultaneously.
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 before rolling starts, carry out.In addition, utilize the moving horizontally preferably of working roll 3 that roller offsetting mechanism 10 carries out to carry out before rolling starts, but also can in rolling, carry out.
In addition, roller offsetting mechanism 10 can be arranged on backing roll 5a, 5b, and be arranged on the lower side of downside backing roll 5e and/or the upper side of upside backing roll, by making the backing roll 5e can knee-action, also realize the knee-action of the working roll 3 of intention thickness of slab control.
