Definitions

  • the invention relates to a device for metered introduction of pouring aids, in particular mold powder, in a continuous casting mold, one on the broad side of the Continuous casting mold arranged several over the continuous casting mold has end spouts, at least a funding in the distribution channel the pouring aid promotes steadily to the outlet nozzle, each outlet nozzle has a grant assigned to it that the pouring aid through a discharge opening of the spout promotes in the continuous casting mold.
  • DE 30 44 591 A1 has already disclosed a device for metering Introducing mold powder into a continuous casting mold with the help of a gaseous medium Casting powder storage containers connected over the continuous casting mold ending spout proposed.
  • a control device for the gaseous medium provided a meterable pourable powder discharge allowed.
  • FR-A-2 463 397 discloses a metering device Introducing powder into a mold, one above the Mold-arranged distribution channel several over the mold ending spout with upstream pockets for admission of the powder.
  • the powder in the distribution channel promotes to the pockets. Every spout is angled towards the assigned pocket and has one Nozzle, which is supplied with compressed air via a line.
  • the respective line is pressurized with compressed air, which empties the outlet nozzle. In this way the powder should be targeted at a specific dose Areas of the bath in the mold are abandoned. An exact portioning of the powder is possible with this device however not possible.
  • the invention is based on this prior art the task underlying the continuous casting mold over its full Width with small, precisely dosed portions of the pouring aid to supply as needed and the discharge of the casting aids to the casting width and the thickness of the Adapt the continuous casting mold, in particular to adapt it to requirements Add pouring aids to several places on the mold level can.
  • each outlet nozzle from a T-shaped tube with two horizontal sections and a vertical section is formed, wherein a horizontal section below the distribution channel runs in the direction of the continuous casting mold, the opposite horizontal section a dosing cylinder for conveying the pouring aid takes up and the vertical section the Distribution channel with the horizontal sections of the T-shaped Rohres connects.
  • the discharge nozzle designed according to the main claim has a dosing cylinder for conveying in portions and the Pouring aids, preferably from a valve-controlled Air cylinder is operated.
  • the T-shaped tube forms together with the dosing cylinder a dosing chamber, which over the vertical section of the T-shaped pipe from the distribution channel is filled.
  • the Dosing cylinder a delivery stroke and conveys the casting aid from the dosing chamber towards the discharge opening of the spout.
  • casting aids largely depends on the type of steel, the composition of the pouring aid and the Temperature of the tundish. Casting aids become dependent on consumption automatically updated in sufficient quantity.
  • the motor-driven are used as cross conveyors in the distribution channel Continuous conveyor, for example a conveyor belt (Spoon belt) or a screw conveyor.
  • the the Funding allocated to outlet spouts can be individually or can be controlled in groups. This measure can the casting surface is specifically supplied with casting aids become.
  • the one running in the direction of the continuous casting mold opens horizontal section of the T-shaped tube at the end into the side of a funnel with the discharge opening on its underside having.
  • the feed for the starting powder usefully opens into the top opening of this funnel.
  • the feeder can be used as a plate be formed with a heating device that the starting powder preheats.
  • the starting powder is, for example, with a driven by a valve-controlled air cylinder Slider on the plate conveyed in the direction of the funnel.
  • the device according to the invention can be space-saving below of the mold feeder (tundish) Arrange.
  • the device can be moved, in particular movable in the direction of the broad side of the continuous casting mold be trained.
  • the distribution channel can be used to loosen up the pouring aids have a gas supply.
  • the feeders expediently Control valves on.
  • the distribution channel of the device according to the invention over at least one line with one regularly above of the distribution channel arranged storage container for the Casting aids connected.
  • a gas supply can be in the line and / or a heater can be installed. This also serves Gas supply of the loosening and the heating of the preheating of the Mold powder.
  • the line can have shut-off devices, to interrupt the supply of pouring aids.
  • the device designated as 1 for metering The introduction of casting powder is on the broad side of a continuous casting mold 2 arranged. It essentially consists of one Distribution channel 3, several above the continuous casting mold 2 ending spouts 4 has. The below the Tundishs 5 arranged device 1 is laterally in over 2 the distribution channel 3 opening lines 6 from one in the Figures not shown storage container with pouring aids provided.
  • the discharge nozzle designated overall by 4, is, in particular 3 shows the sectional view, from a T-shaped tube with 2 horizontal sections 7, 8 and a vertical section 9 is formed.
  • the horizontal one Section 8 runs in the direction of the continuous casting mold 2, while the opposite horizontal section 7 one Dosing cylinder 11 for conveying what is schematically indicated in Figure 3 Pouring aid 12 picks up.
  • the metering cylinder 11 has two piston heads 13, 14 which together with the vertical section 9 a metering chamber 15 form.
  • the pouring aid 12 By moving the metering cylinder 11 along the Stroke 16, the pouring aid 12 in portions Direction of an end of the vertical section 8 arranged Supported funnel 17. Points at its bottom the funnel 17 has a discharge opening 18 through which the Pouring aid 12 is placed in the continuous casting mold 2.
  • the dosing cylinder 11 is actuated with a compressed air cylinder 19, which is aligned with the horizontal section 7 on the Outlet connection 4 is flanged.
  • the funnel 17 there is a total of 21 Feeder arranged with starting powder. It consists of a heatable plate 22, the end face in a above chute 27 opening into the upper opening 23 of the funnel 17 transforms.
  • the detailed view of the lines 6 arranged on both sides of the distribution channel 3 in FIG. 5 shows two gas feeds 25 and three heating rods 26 protruding into the free cross section of the line 6.
