Definitions
- the invention relates to a grinding device for grinding a metallic product, in particular a continuously cast slab, a billet or a block.
- Continuously cast products in particular slabs, are usually subjected to surface treatment by grinding after the continuous casting in order to achieve a sufficient quality in the further processing of the product.
- the slab is usually reciprocated longitudinally in a reversing motion under a grinder. At the end of each reversing movement, the grinder performs a stepwise cross-feed motion until the entire slab surface is ground.
- the slab is stored on a grinding table lying on its long broad side.
- the grinding performance can be increased by increasing the width of the grinding wheel, if at the same time the drive power of the motor is increased (eg from 315 kW to 630 kW with a doubling of the grinding wheel width); there- with the specific engine power can be kept the same size based on the grinding wheel width.
- the width of the grinding wheel is limited by the manufacturing process of the grinding wheel and the strength of the binder of the grinding wheel; in practice, no grinding wheels more than 150 mm wide are used.
- the disadvantage is the following: During grinding, the contact zone between the grinding wheel and the grinding material travels across the width of the grinding wheel, specifically the contact zone periodically reciprocates due to the reversing of the slab from the respective outer edge of the grinding wheel to the center of the grinding wheel. Broadening of the contact zone and an increase in the drive power therefore do not necessarily lead to the desired increase in the Abschliff amalgam, but possibly only to the fact that increases the service life of the grinding wheel (s).
- the invention is therefore an object of the invention to provide a grinding device in which said increase in drive power leads directly to an increase in the Abfiffrfrate. Accordingly, the economics of the grinding process when grinding metallic products such as slabs, billets and blocks to be improved.
- the grinding device has at least two grinding units, each grinding unit having a holder for a grinding unit, wherein a grinding unit has at least one driven grinding wheel and wherein the grinding wheels are arranged so that their axes of rotation parallel to each other.
- Each holder is preferably pivotally mounted about an axis which is parallel to the axis of rotation of the grinding wheel and at a distance therefrom.
- means may be present with which the distance between the pivot axis of the holder of the axis of rotation of the grinding wheel can be adjusted.
- These means for adjusting the distance can be advantageously designed as an eccentric.
- each holder comprises a linear guide with which the grinding wheel can be moved perpendicular to the axis of rotation of the grinding wheel and preferably horizontally.
- Each grinding unit may further comprise a loading device for applying a defined pressure force of the grinding wheel on the metallic product, wherein the loading device comprises in particular a grinding pressure cylinder-piston system.
- the grinding units may be pivotable together about an axis which is arranged perpendicular to the axis of rotation of the grinding wheels and vertically, wherein the pivot axis is preferably in the region of the grinding wheels, in particular between the grinding wheels of the two grinding units.
- the grinding wheels of the grinding units are preferably arranged directly next to one another. They can have different grain and / or structure.
- the grinding wheel can preferably be directly driven by the drive motor without the interposition of a transmission or other elements.
- Fig. 1 shows schematically the side view of a grinding unit of a grinding device
- FIG. 2 schematically shows the view "X" of the grinding unit according to FIG. 1;
- Fig. 3 shows schematically the top view of a grinding device with two grinding units
- Fig. 4 is an enlarged view of the area of the grinding wheels of
- a grinding unit 3, 4 is shown, which is part of a grinding device 1, which can be seen in Fig. 3.
- the grinding unit 3, 4 has a holder 5, 6, which is designed as a pendulum bracket with counterweight 19.
- the holder 5, 6 is pivotally mounted about a pivot axis C, D.
- the grinding unit 3, 4 has a grinding unit 7, 8 and has a mounted grinding wheel 9, 10 which is driven directly by a drive motor 11, 12.
- the grinding wheel rotates about a rotation axis A, B.
- an only indicated loading device 14, for. B. designed as a piston-cylinder system provided.
- means 13 with which the distance between the pivot axis C, D and the axis of rotation A, B can be changed.
- the axis of rotation A, B can be adjusted or adjusted relative to the pivot axis C, D in the horizontal direction H by means of an eccentric.
- the material to be ground d. H.
- the metallic product 2 is oscillated back and forth under the grinding wheel 9, 10, which is indicated by the direction of movement G of the product 2.
- Fig. 3 the entire grinding device 1 is shown, wherein again the direction of movement G, which executes the product 2 during a grinding stroke, is located.
- the two holders 5, 6, ie the two pendulum brackets are arranged parallel to one another and a respective grinding unit 7, 8 with a grinding wheel 9, 10 is arranged in its end region.
- the position of the grinding wheel 9, 10 are changed in the horizontal direction; ie, the distance a or b between the pivot axis C and D of the holder 5, 6 to the rotation axis A and B of the grinding wheel 9, 10 can be slightly changed.
- the displacement in the horizontal direction H produced by the eccentric 14 is entered with ei or with ⁇ 2 .
- the entire grinding device 1 can pivot about an axis E, which extends in the vertical direction V.
- the pivoting angle to the longitudinal axis (perpendicular to the pivot axis C, D and in this case pointing in the horizontal direction H), is marked with ⁇ and here is 90 °.
- the pivot point E is located between the two grinding wheels 9, 10th
- Fig. 4 it can be seen that the aim is to place the two grinding wheels 9, 10 as close to each other as possible.
- the grinding wheels 9, 10 are each received on a grinding wheel receiving 15 and 16.
- the fixing of the grinding wheels 9, 10 takes place by means of a fastening ring 17 or 18. Between the two fastening rings 7, 18 there is only a small gap. Accordingly, there is a minimum distance between the two grinding wheels 9, 10, which is limited only by the width of the mounting rings 17, 18 and by a small clearance between them.
- the two grinding wheels 9, 10 in succession grind each with separate contact zones to the product. 2
- the larger / coarser grit wheel may first perform a rough grinding operation followed by a finishing operation performed by the finer grit wheel.
- the direct drive of the grinding wheel which is mounted on the drive shaft of the (electric or hydraulic) drive motor, as it were. But it can also be provided that the drive via transmission, V-belt, spindles, etc. takes place indirectly.
- a grinding unit with its own drive motor is preferably provided for each grinding unit. If the said indirect drive mode is provided, it is also conceivable that a single drive motor drives the at least two grinding wheels.
- Each of the grinding units 7, 8 can be equipped with more than one grinding wheel 9, 10.
