Definitions

  • ABSTRACT Apparatus for loading hot topping slabs onto a device for placing them in an ingot mold includes a base, a moveable slab carrier and means forlocating the base and device to allow transfer of a slab from the slab carrier on to the hot topping device.
  • All types of automatic hot topping apparatus have holding means on them for holding slabs of refractory heat insulating material in position.
  • Suitable holding means are clips, hooks and lugs.
  • apparatus for loading slabs of refractory heat-insulating material onto hot topping apparatus which loading apparatus comprises a base, a slab carrier moveable on the base into and out of co-operation with holding means on the hot topping apparatus, means for locating the hot topping apparatus in fixed position relative to the base, and means for moving a slab on said slab carrier into engagement with the holding means on the hot topping apparatus when the slab carrier is in a cooperating position with respect to the holding means.
  • the preferred form of holding means on the hot topping apparatus is one or more cylindrical projecting lugs.
  • the slab carrier may include one or more rods, each of which passes through a suitable aperture in each of a load of hot topping slabs, the rod engaging axially with the lug when the slab carrier is brought into co-operation with the holding means. Each slab is then slid axially along the slab carrier rod(s) and onto the projecting lugs.
  • each rod on the slab carrier may terminate in a tapered pin which engages with a corresponding aperture in the end of each lug.
  • the present invention provides a method of hot topping which comprises loading a plurality of slabs of refractory heat-insulating material into a magazine, dispersing slabs one-by-one from the magazine, automatically applying the slabs to hot topping apparatus, locating the hot topping apparatus within an ingot mould or ingot mould headbox and transferring the slabs from the hot topping apparatus onto the wall of the ingot mould or ingot mould head box.
  • the present invention also provides a method of loading slabs of refractory heat insulating material onto hot topping apparatus, which method comprises the steps of locating the hot topping apparatus in a fixed position relative to loading apparatus as set forth 'above, advancing a slab carrier into cooperation with the hot topping apparatus, transferring a slab from the slab carrier to the hot topping apparatus automatically to locate it in position thereon and subsequently with drawing the slab carrier.
  • Automatic hot topping apparatus generally comprises a frame of the same general shape as the ingot mould or head box cavity, and this is thus usually of rectangular section. It is thus necessary to load a slab onto each wall of the hot topping apparatus and this may be done either by using a separate loading apparatus'for each wall and moving the hot topping apparatus each time, or preferably using a plurality of loading apparatus.
  • a particularly preferred arrangement for rectangular section apparatus is to use two loading apparatus, each of which loads a long slab onto two adjacent walls thereof.
  • each slab may be provided with one or more notches to permit the slab to bend around the corner of the hot topping apparatus and means may be provided on the loading apparatus to engage the free end of a slab, after one end has been engaged on one wall of the hot topping apparatus, to bend the free end round into engagement with an adjacent wall of the hot topping apparatus.
  • FIG. 1 is a perspective view of the loading apparatus
  • FIG. 2 is a plan view of the apparatus of FIG. I and showinghot topping apparatus in position
  • FIG. 3 is a side elevation of the apparatus-of FIG. 2.
  • the arm 22 carries at its extremity a vertically extending rod 25.
  • a hydraulic piston/cylinder 29 extends between the roller carriage l2 and a cross member 30 attachedto the tracks 11.
  • a hot topping apparatus 31 is shown very diagrammatically as a frame of generally rectangular cross-section and including spring operated latches 32 on each face.
  • the apparatus 31 also carries projecting pins 33 having recesses (not shown) for the reception of the pins 15 of the device.
  • each slab is of a length such that it forms two side walls 36 and a corner 37, the three members being interconnected by suitable hinge means which may be a flexiblebacking strip on the slab or a thinner section of the material of the slab itself, made by providing grooves 38 in the slabs.
  • the apparatus 31- is then placed in the correct position, i.e., as shown in FIG. 2 by lowering it into a suitable cradle or locating means and piston/cylinder 29 is then operated to move the roller carriage 12 forward so that the pins 15 engage in the recesses in the pins 33.
  • Piston/cylinder .19 is then operated to move the cross-member l7 and push the slabs 35 along the rods 13 until thefront slab engages over pins 33.
  • latch 32 is now in position to engage the front slab and prevent its removal from apparatus 31.
  • the slab, located on the pins 33, has by now moved sufficiently forward to free end 40 from the end of the lower support rod 21, and, by virtue of the weight of the slab and notches 38, the end 40 swings freely to the position indicated by 40a.
  • Piston/cylinder 24 is then actuated to its contracted position so that when the shaft 25 contacts the back face of the slab and pushes end 40a round until the slab contacts the adjacent wall of the apparatus 31, and isheld by latch 32.
  • a guide face 42 is provided on the cradle supporting the apparatus 31.
  • Piston/cylinder 24 is then extended and piston/cylinders l9 and 29 retracted to leave the L-shaped slab held in position by the latches 32 and extending around two adjacent side walls of the apparatus 31.
  • the other two side walls of apparatus 31 may be lined simultaneously by the use of a second loading apparatus acting on these two walls or alternatively the apparatus 31 may be lifted, rotated through 180 and the same loading device used to line the other two walls.
  • the slabs are preferably assembled in packs of suitable size, with the slabs pre-aligned, preferably, by rods passing through the holes in the slabs.
  • These rods may have an aperture in their ends so that they can be engaged over pins 15 and the whole pack of slabs slid off the packing rods and onto rods 13.
  • a hot topping apparatus having means ,for holding slabs of refractory heatinsulating material in position for subsequent placing in a mould or head box, apparatus for loading said slabs of refractory heat-insulating material onto said hot topping apparatus, said loading apparatus comprising a base, a slab carrier moveable on the base into and out of cooperation with said holding means on the hot topping apparatus, means for locating the hot topping apparatus in fixed position relative to the base, and means for moving a slab on said slab carrier into engagement with the holding means on the hot topping apparatus when the slab carrier is in a cooperating position with respect to the holding means.
  • the slab carrier includes at least one rod which passes through a suitable aperture in each of a load of hot topping slabs, the rod engaging axially with a cylindrical projecting lug on the hot topping apparatus when the slab on the slab carrier terminates in a tapered pin adaptedto engage a corresponding aperture in the end of each lug on the hot topping apparatus.
