Definitions

  • the subject of the invention is an apparatus for removing burrs formed at the ends of the sections of a continuous casting product, during cutting with a torch, comprising at least one knife applied by jacks or equivalent means against the face of the cast product. on which are the burrs and means for ensuring the relative movements of the knife and the sections of cast product.
  • An apparatus of this type is described in French patent 82.05918.
  • the knife has the shape of a very open V, the point of which is situated approximately on the midline of the face of the cast product and its cutting edge is situated in a plane parallel to the face of the cast product on which lie the burrs.
  • the cast product has a large width (slabs)
  • the object of the present invention is to remedy this drawback and to ensure good deburring of the cast product over its entire width, despite the bulging of the face to be deburred.
  • the deburring device which is the subject of the invention is characterized in that the plane defined by the cutting edge of the V-shaped knife is inclined relative to the theoretical plane of the face of the cast product to be deburred so that the tip of the V is farther from this plane than the ends of the wings of the V.
  • the angle of inclination which is small, is determined by tests. Means can be provided to adjust this tilt. We can, for example, adjust the position of the beam carrying the knife relative to the supports to which are fixed its ends.
  • the knife will be formed from blades with rectangular section, the four edges of which can be used successively as a cutting edge which will considerably lengthen their service life.
  • the blades will be fixed on their support so that the angles formed by their faces with the theoretical plane of the face of the cast product to be deburred are all greater than that formed with this same plane by the plane of the cutting edge of the knife, so that the knife does not come. in contact with the cast product only along its cutting edge.
  • the deburring device shown in the drawings is placed on the discharge conveyor of a continuous slab casting machine, downstream of the flame cutting zone, and intended to remove the burrs which form at the ends of the sections. slab, on their underside, when cutting the product poured using a blowtorch.
  • This device comprises a frame 10 formed of two lateral flanges, arranged vertically and braced by horizontal beams.
  • the flanges are cut to form three pairs of vertical slides, open at their upper end.
  • the middle slides receive the bearings of two rollers 12 and 14 placed one above the other; the bearings of the lower roller 12 rest on the bottom of the slides, possibly with interposition of shims, and the bearings of the upper roller 14 are suspended from the rods of the pistons of two hydraulic cylinders 16 mounted on caps 18 fixed on the frame and closing the upper end of these slides.
  • the lateral slides receive chocks 20 on which are fixed the ends of two beams 22 carrying the knives 24. These chocks are suspended from the caps 18 by means of hydraulic cylinders 26.
  • each knife is formed of two blades 24a and 24b arranged in a very open V whose tip is located in the plane of symmetry of the device. These blades have a rectangular section and are fixed by screws to the beam 22.
  • the plane defined by the cutting edges 28 of the two blades is inclined at an angle Y, relative to the theoretical plane ZZ of the face of the slab to be deburred, which coincides with the bearing plane of the rollers of the discharge conveyor , so that the tip of the V formed by the edges 28 is located away from and below the plane ZZ when the ends of the wings of the V are in this plane.
  • the blades 24a and 24b are inclined relative to the plane ZZ by an angle X greater than the angle Y to prevent them coming close behind the slab and thus have the certainty that they are in contact with it only along their cutting edge.
  • FIGS. 4a, 4b and 4c are, respectively, a plan representation of the cutting edge 28 of the knife 24, a view in elevation along arrow F and a view in elevation of a knife blade.
  • FIGS. 4a, 4b and 4c are, respectively, a plan representation of the cutting edge 28 of the knife 24, a view in elevation along arrow F and a view in elevation of a knife blade.
  • the V-shaped arrangement of the blades has been accentuated.
  • the angle of the V is close to 180 °, as seen in Figure 2.
  • the fixing of the knife-carrying beams 22 on the chocks 20 is provided to allow the tilting of the knives to be adjusted, that is to say the value of the angles X and Y.
