Definitions

  • the invention relates to a device for pouring molten metal, in particular cast iron, into ingot casting molds, comprising in a ingot casting machine an endless conveyor belt equipped with ingot casting molds for transporting the ingot casting molds from a casting station to an ingot emptying station, and vice versa, each ingot casting mold in the casting station as it passes through the casting device is filled with molten metal with the mold cavity pointing upwards, which is introduced into the mold cavities from a transport container via a guide element.
  • Pig casting machines are known. It is known that liquid pig iron is either fed into a steel mill after tapping in a blast furnace or, if it cannot be processed immediately, cast in the form of ingots, the so-called ingots, for storage or further transport. Pig iron pigs have different weights depending on the intended use, usually a pig weighs around 6 kg.
  • Generic casting machines are used for the production of pig iron.
  • a ingot casting machine which is composed of a casting station, at least one endless conveyor belt and an emptying station for the solidified ingots at the deflection point of the endless belt.
  • Several ingot molds or molds are attached to each endless conveyor belt. After pouring molten material into the ingot mold, it is transported to the emptying station, usually in an upward direction, by means of an inclined conveyor.
  • each ingot casting mold is automatically removed empties, and the solidified ingot is collected in suitable containers or on a conveyor belt.
  • the molten pig iron to be cast is poured from a transport vessel, for example a so-called torpedo car, into a fire-resistant, lined gutter which is slightly inclined towards the casting machine.
  • This channel ends over the molds running around the machine's casting belt.
  • the molten pig iron running through the channel falls freely into the mold over the end edge of the channel.
  • the height of this edge above the mold is relatively large.
  • the pouring jet strikes the full width of the mold, and therefore also the webs between the actual depressions for the ingots, the so-called mold troughs. This leads to iron being sprayed away, as a result of which the casting belt of the machine is continuously contaminated by adhering iron splashes and is ultimately impaired in its function, which necessitates undesired maintenance.
  • the thickness of the refractory layer at the bottom of the trough and its outer cladding made of sheet steel increases the drop height of the liquid iron into the mold and in this way increases the tendency to splash and overflow the mold.
  • the front edge of the channel is subject to considerable wear, so that the point of discharge of the liquid iron shifts disadvantageously in the horizontal and vertical during operation.
  • the trough has no storage capacity for liquid iron, so that on the one hand irregularities in the iron supply from the transport barrel, e.g. due to wear of the refractory material in the transport vessel, cannot be compensated for, and on the other hand bath movements in the melt, which are caused by a comparatively large fall of the iron from the transport vessel, cannot be dampened and apart from the conditions in the mold punch through.
  • the invention has for its object to improve and design a device for pouring molten metal, in particular cast iron, of the type mentioned in the preamble of claim 1 such that the aforementioned disadvantages, difficulties and limitations of the technology are overcome, the design of the device being such It should be uncomplicated and clear that it can be used on any existing casting machine, and this use is expressly not intended to be exclusively linked to pig iron as the material to be cast. Furthermore, the device according to the invention should meet the highest safety requirements when operating a casting machine.
  • the guide member as a distributor with a trough-like part for collecting the molten metal from the transport container to form a Amount of memory, as well as with a casting with at least one tubular spout, which are assigned to each other while leaving a communicating lower connection opening in a common siphon-like partition.
  • liquid iron is first poured from a transport trolley into a trough-like part of a distributor for collecting the jet of the molten metal, the distributor being divided into two parts by a siphon-like wall, namely into a collecting part for the jet of the molten metal from the transport container , in which turbulent flow conditions prevail, whereby in the front part, which is a tubular has a shaped spout, a calming of the melt bath occurs.
  • the tubular spout present in the bottom of this part can be guided as close to each individual ingot recess of the mold as the shaped edges allow.
  • the device according to the invention for pouring molten metal uses known construction principles in the continuous casting of steel, such as known distributor channels, while adapting to the special circumstances in a casting machine.
  • the spouts are subject to comparatively little wear and tear, the point of application in each mold trough changes only negligibly during operation.
  • the point of application of the liquid iron can be brought closer to the mold than with a channel construction.
  • the tendency to spray is reduced.
  • the cast part of the distributor at the top with a predeterminable amount of cast iron ensures a steady and even inflow of liquid metal.
  • the amount of memory in the distributor can bridge the times required for a change to a new transport container without the system having to be stopped in its function.
  • the principle of operation of the pouring device according to the invention is independent of the exact number of pouring tubes used and the shape of the distributor.
  • the device can therefore be used on any casting machine for liquid metal, which works on the principle of a pig casting machine for pig iron or other liquid metal.
  • the device for pouring molten metal, in particular cast iron, into ingot casting molds 1 comprises, in an ingot casting machine, an endless conveyor belt 2 equipped with ingot casting molds 1 for transporting the ingot casting molds from a casting station 3 to an ingot emptying station, and vice versa, each ingot casting mold 1 in the casting station 3 as it passes through Pouring device with the mold cavity facing upwards is filled with molten metal, which is introduced from a transport container 4 with a pouring jet 5 via a guide element into the mold cavities.
  • the guide element is designed as a distributor 6 with a trough-like part 7 for collecting the beam 5 of the molten metal from the transport container 4 to form a storage quantity 8, and with a casting 9 with at least one tubular spout 10, which leaves a communicating lower connection opening 11 free are assigned to each other in a common siphon-like partition wall 12.
  • the distributor 6 is arranged with its spout 10 at a comparatively short distance above the mold cavity of the casting molds l. This avoids splashing of liquid cast iron and thus contamination and damage to the endless conveyor belt 2 of the ingot casting machine. Because the distributor 6 contains a storage quantity 8 of liquid metal, in particular cast iron, it is necessary, for example, during a change of the transport container 4 or in the event of a fault in the ingot casting machine, to temporarily interrupt the escape of molten metal from the spout 10 and, in some cases, to interrupt the metal jet 5 may be possible.
  • a closure member 13 is associated with the tubular spout 10. The closure member 13 has a closure plug which can be placed from above through the molten bath 14 onto the pouring opening 10 and which is operatively connected to a remote-controlled trigger device 15.
  • the triggering device 15 is controlled by a control device 16 for monitoring the operation, such that it automatically closes the spout 10 in the event of an interruption in operation.
  • an operation monitoring unit 17 can preferably be assigned to the casting machine, which cooperates with the control device 16 of the casting station 3 in such a way that a corresponding change in the operation of the casting station is initiated when the operating condition of the casting machine changes or is disrupted.
  • a change in the bath height or the storage quantity 8 of liquid metal in the distributor 6 can be set.
  • the distributor 6 is assigned a device 18 for monitoring the height of the melt pool 8, which corrects the inclination of the transport container 4 accordingly if a predetermined height margin is exceeded or undershot. As a result, the outflowing cast steel 5 or the amount of outflowing molten metal is influenced.
  • the principle according to the invention of the casting device for molten metal, in particular cast iron, in ingot casting molds is independent of the number of casting tubes 10 used and of the shape of the distributor 6 or its trough-like part 7 and casting part 9.
  • the device can be used on any casting machine for liquid metal can be used, which works on the principle of a pig casting machine, for example for pig iron.
  • the use of the casting device according to the invention is of essential importance with regard to the development of new high-performance pig casting machines.
