Abstract
The utility model relates to a high precision sheet and strip mill, which is used for the production of the sheet and strip materials. The lower part of the roller seat (5) is provided with a supporting element (2), a supporting element (3), and a sliding block (4). The spindle of the supporting roller (6) and a backing bearing on the spindle of the supporting roller are eccentrically arranged. Since the sliding block can be adjusted as the differences of the width of the rolling elements; the deformation of the supporting element can compensate the deformation of the bottom and the top of the rack, and accordingly, the shape of the seams of the working roller can basically not change as the change of the rolling pressure. Accordingly, the lateral thickness difference of the sheet and strip materials can be greatly reduced, and the shape of the sheet can not mutually interfere with the width control of the sheet. Since the roller shape is easy to be adjusted, the abrasion of the roller, the heat convexity, and the irregular feeding can be conveniently compensated. The high precision sheet and strip mill is especially suitable for the high-precision production of the wide sheet and strip materials.
Description
The utility model belongs to a kind of steel rolling equipment, relates in particular to a kind of band mill.
The normal milling train that uses of strip material production has two rollers, four rollers and multi-roll mill.For four-high mill, because screwdown gear is positioned at the roll neck place of roll, when rolling, working roll will inevitably produce bigger flexural deformation.Multi-roll mill adopts multi-point support to reduce the flexural deformation of roll, beam of uniform strength form is made at the bottom and the top of frame, increase the distortion of memorial archway limit portion artificially, eliminate the lateral thickness difference of stocking with part, yet the backing roll two ends will apply a harmful moment of flexure to working roll under the effect of draught pressure, make the working roll two ends produce bigger flexural deformation, thereby make the strip material produce lateral thickness difference.In addition, because the stress deformation of multi-roll mill frame itself is very complicated, the distortion of the beam of uniform strength at frame bottom and top is difficult to and the straight desired distortion of assurance roll gap matches, in case and the frame completion of processing, it is made amendment is impossible.
The flexural deformation that not only will as far as possible reduce roll during actual production also should constantly be adjusted roll shape according to billet size, roller heat convex degree learning and roll wear situation flexibly to the harmful effect that strip material lateral thickness difference produces.The effective method of adjusting the multi-roll mill working roller is the roll shape adjustment of moving axially of band tapering intermediate calender rolls and backing roll, moving axially of band tapering intermediate calender rolls can cause roller to press the rapid increase of power at the intermediate calender rolls back indirectly, the wearing and tearing of intermediate calender rolls back and work roll surface contact position are accelerated, also can cause working roll roll surface indentation when serious, even influence the surface quality of stocking.The backing roll roll shape guiding mechanism that special fair 1-53126 of Japan Patent and special fair 2-18163 announce utilizes eccentric rotation to come certain part of center roller to apply bending force, because the composite bending modulus of backing roll axle is very big, it is also very big to make it produce strain institute externally applied forces, is very difficult so roll gap is effectively adjusted; In addition, the roll shape guiding mechanism be to be installed, must be in the bottom and the top boring of frame, this to the rigidity of frame particularly its intensity will have a negative impact undoubtedly.
Task of the present utility model is: provide a kind of can the made with high precision width easy to adjust, the work roll gap of very big strip material, roll profile do not change, and can make control of plate shape and thickness of slab control separate stiff mill with draught pressure.
For finish above-mentioned task, the technical scheme that the utility model adopted: supporting member is set below roller seat; The slide block that can move along body of roll direction is set on roller seat or supporting member; The axle of back lining bearing and backing roll is arranged off-centre.
The supporting member that is provided with below roller seat can be made up of the different wedge of several thickness, also can be several screw thread tunable arrangements.
Supporting member (screwdown gear) can be arranged in pairs or groups with the roll shape adjusting device of other form, and is same, and the roll shape adjusting device also can be arranged in pairs or groups with the screwdown gear of other form.
For narrow boards band and strip rolling mill or the little milling train of strip material wide variety slide block can be set.
Because adopt technique scheme, the utility model can be produced the very big strip material of width, in addition, because of the bottom and the top of frame need not boring, therefore, the milling train rigidity is very big.
Because roller seat or supporting member are provided with the slide block that can regulate according to the rolled piece width, in the operation of rolling, the deformation energy compensation frame bottom of supporting member and the distortion at top, so the bending of work roll distortion does not change with the variation of draught pressure basically, keep straight when rolling thereby make working roll be sewn on, the lateral thickness difference of strip material is greatly reduced, and thickness of slab control and the control of plate shape are not disturbed mutually.
Because back lining bearing and roll axle are arranged off-centre, the adjustment of roll shape only needs mandrel and needn't apply moment of flexure to the very big axle of composite bending modulus, so the roll shape adjustment is very easy.
Because the bending of work roll distortion does not change with the variation of draught pressure substantially, the wearing and tearing of roll and the variation of hot convexity can be compensated by adjusting backing roll roll shape adjusting device easily, therefore, the control of the design of roll original roller type and the roll shape in the operation of rolling becomes very easy.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is used for the front view of twelve high mill for the utility model.
Fig. 2 is used for the side view of twelve high mill for the utility model.
The appearance profile curve synoptic diagram of backing roll when Fig. 3 is three for back lining bearing in the utility model.
The appearance profile curve synoptic diagram of backing roll when Fig. 4 is five for back lining bearing in the utility model.
As Fig. 1, shown in 2, the milling train that the utility model provides is by working roll (8), intermediate calender rolls (7), backing roll (6), roller seat (5) and (10), supporting member (2), (3) and slide block compositions such as (4), backing roll is bearing on roller seat (5) and (10) with the form of multiple spot beam, roller seat (5) can move up and down by moving horizontally of supporting member (2), thereby realize the adjustment of roll gap, be provided with slide block (4) in the below of roller seat (5), on all or part of backing roll (6), be provided with the roll shape guiding mechanism, its structure is that several all or part of back lining bearings (12) that is arranged off-centre with respect to axle are installed on backing roll axle (11), by adjusting the corner of axle, the appearance profile of backing roll can be controlled to as Fig. 3, shape shown in Figure 4 is to control template and lateral thickness difference effectively.
