Definitions

  • the invention relates to a device for grinding the surfaces of continuously cast slabs, also thin slabs and / or hot-rolled or hot-rolled strips, during their feed in the rolling mill to remove objectionable surface sections such as scale layers and / or texture defects or the like by means of rollers spanning slab surfaces.
  • Such a grinding device is e.g. B. become known from DE-OS 36 00 144.
  • one sanding roller is arranged at a right angle above and below the material to be sanded, the length of the sanding rollers exceeding the width of the sanded material.
  • the grinding rollers have a so-called CVC contour, so that the surface design of the material to be ground can be influenced by axially displacing the grinding rollers.
  • the grinding device must first and foremost remove material, and the possibility of influencing the surface shape takes a back seat.
  • the sanding roller is no longer sufficient to ensure removal. Since the grinding roller lies on the surface of the grinding material over a large area, it would only be able to achieve a corresponding material removal under considerable contact forces.
  • the rigid grinding roller - disregarding roller bending - primarily only reaches the most distant pieces of material to be ground will. If there are flaws to be ground out in small recesses, these flaws cannot be ground out with the rigid roller.
  • belt grinding machines have also already been proposed, with which smaller and deeper areas of the material to be grinded can also be processed, but with which, likewise, no sufficient grinding pressure is applied to the material Grinding material can be applied.
  • the invention is therefore based on the object of developing a grinding device of the generic type in such a way that all areas of the grinding material can be processed without problems and that a sufficiently high grinding pressure can be exerted on the grinding material.
  • the subdivision of the grinding roller into several grinding rollers means that the large, rigid support of the grinding wheel on the material to be ground is avoided.
  • the resilient lamellae in connection with the high speeds of the shaft carrying them, ensure that the outer contour of the grinding rollers corresponds to the usual roller crowns due to flying forces, but that the individual lamellae are able to adapt to the surfaces of the material to be grinded in the pressure area, so that they do not, as in the case of Generic rigid roller is first sanded the most protruding area of the material to be ground and only when this is ground, the not so protruding areas, but that all areas of the material to be ground can be ground simultaneously and material can be removed accordingly at all points.
  • the drive and the adjustment of the grinding rollers take place via the common shaft, so that a large-area, uniform grinding of the grinding material is possible with relatively little effort.
  • the lamellae according to claim 1 can be brushes or, as claimed in claim 2, so-called lamella grinding rollers, in which only the free end areas of the lamellae contribute to the grinding process. If, as claimed in claim 3, spacer elements are provided between adjacent fins, the individual fins can cool better in the air surrounding them. However, there is also the possibility, as generally proposed in claim 10, to provide coolant nozzles for the fins.
  • the grinding rollers In order to be able to reduce the contact forces and to stress the lamellae less, there is the possibility according to claim 4 to provide distances between the grinding rollers.
  • the grinding rollers must be periodically shifted axially in this case, taking care that the lamellas of the outer grinding rollers are not moved completely over the edge area of the grinding material, otherwise the grinding rollers will move back the flanks of which would be moved against the material to be ground, which could destroy the lamellae.
  • the axial displacement speed should be adapted to the feed speed of the material to be ground so that all areas of the material to be ground can actually be processed.
  • a further possibility for processing complete grinding material although there are gaps between the grinding rollers and no axial displacement of the rollers is required, is shown in claim 5, according to which a second shaft is arranged in the grinding material transport direction behind the first shaft, the However, grinding rollers of the second shaft are aligned with the spaces of the first shaft that are free of grinding rollers.
  • the grinding rollers have a certain service life, after which they have to be replaced. To ensure continuous operation of the To ensure grinding device, it is therefore proposed according to claim 6 to provide several shafts equipped with grinding rollers one after the other, so that the used grinding rollers can be exchanged with corresponding changing devices, while the grinding rollers arranged on the other shafts can be used and used for grinding.
  • suction nozzles arranged at least above the grinding material are proposed.
  • the material removed from the grinding rollers located below the material to be ground falls down due to gravity and can be collected with suitable means.
  • the waves are exposed to strong radiant heat, whereby the waves arranged above the material to be ground must also withstand strong convection heat. In addition, there is the heat which arises during grinding and is to be dissipated from the lamellae, so that it can be useful, as proposed in claim 11, to cool the shaft.
  • the shaft has an angle deviating from 90 ° to the longitudinal direction of movement of the grinding material.
  • FIG. 1 shows a thin slab coming from a continuous caster, not shown, as grinding material 1, which moves in the direction of arrow 2 in a rolling mill, not shown. Above and below the grinding material 1, grinding devices 3 to 3 '' '' are arranged. Corresponding grinding devices can of course also be provided on the edges of the grinding material 1.
  • the grinding device 3 to 3 '' '' have shafts 7 mounted on stands 4, 4 'and chocks 5, 5' in stands 6, 6 '.
  • the shafts 7 can be driven in rotation by motors 8.
  • the shafts 7 can be shifted periodically in the axial direction by means of a shifting device 9.
  • the shaft 7 can also be arranged in the axial direction, such as. B. shown in the grinding device 3 '.
  • the grinding device 3 has a multiplicity of grinding rollers 10, 10 ', 10'' Vietnamese arranged closely next to one another, which cover the entire surface of the grinding material 1. The entire surface of the grinding material 1 can thus be processed.
  • the grinder 3 therefore basically does not require a displacement drive 9.
  • the displacement drive 9 proposed here is only used to improve the uniformity of the grinding.
  • the grinding device 3 ' has grinding rollers 10, 10', 10 '' Vietnamese between which distances are provided. Cooling air for the grinding rollers can be blown in in the area of the distances.
  • a pump 11 is used, which is connected to the nozzles 13 via lines 12.
  • the grinding device 3 ' is assigned, for example, a suction nozzle 20 which is connected to a pump 21, by means of which the ground material particles can be suctioned off.
  • These cooling and / or suction devices can of course also be assigned to the other grinding devices.
  • the grinding device 3 ′′ also has distances between the individual grinding rolls 10, 10 ′, 10 ′′ ′′, the grinding rolls 10 of the grinding device 3 ′′ being aligned with the free spaces between the grinding rolls 10 of the grinding device 3 ′. Furthermore, the grinding device 3 ′′ shows a coolant pump 14, from which coolant can be supplied to the corresponding shafts 7 via corresponding lines. This cooling device can also be assigned to each of the other grinding devices.
  • the grinding device 3 '' ' shows that even with a few grinding rollers and a corresponding axial displacement, sufficient removal from the grinding material 1 is ensured.
  • the shaft 7 has further, adjustable bearings 15.
  • the grinding device 3 '''' has a shaft 7 which is arranged at an angle to the other shafts 7. Grinding roller arrangements can of course be provided on this inclined shaft 7, as shown in the grinding devices 3 to 3 '''. Cooling devices 11 to 15 can also be assigned to this grinding device 3 ''''. For continuous operation, several of the grinding devices 3 '''' can be arranged one behind the other, whereby the angle to the direction of travel of the grinding material 1 can be identical for all shafts 7 or can also be inclined differently or in opposite directions.
  • FIG. 2 shows a grinding roller 10, which consists of a hub body 16, from whose jacket 17 lamellae 18 extend. Spacers 19 are provided between the fins 18, which increase the spacing of the fins 16 from one another, so that better cooling of the individual fins 18 is possible.
