Definitions

  • the invention relates to a device for pouring cast iron into ingot molds, comprising in a ingot casting machine with ingot casting molds equipped endless conveyor belt for transporting the ingot molds from a pouring station to an ingot emptying station, and vice versa, wherein each ingot mold in the casting station as it passes through the casting device is filled with molten metal pointing upwards with molten metal from a transport container via a guide element, introduced into the mold troughs becomes.
  • Liquid pig iron is known to be either fed to a steel mill after tapping in the blast furnace using pans or, if it cannot be processed immediately, in the form of Ingots, the so-called ingots, for storage or further transport cast iron pig pots have according to the intended use different weights, usually one pig is about 6 kg heavy.
  • Generic casting machines are used for the production of pig iron to use.
  • a pig casting machine which consists of a Casting station, at least one endless conveyor belt and an emptying station for the solidified pigs at the deflection point of the endless belt.
  • On each endless conveyor belt there are several ingot molds or Molds attached. After pouring molten material into the Ingot mold is transported to the emptying station, usually in Upward direction, by means of a feeder.
  • each ingot casting mold is emptied automatically, and the solidified ingot in suitable containers or on a conveyor belt collected.
  • Document DE-A 2 850 563 describes the technology of a casting process with a ladle and the mechanization of the casting process.
  • the invention has for its object a device for pouring Cast iron, the type mentioned in the preamble of claim 1 to improve and to design that the aforementioned disadvantages, difficulties and Limits of technology are overcome, the design of the device should be so uncomplicated and clear that it can be used on any existing Pig casting machine can be used. Furthermore, the device according to the invention the highest safety requirements during operation correspond to a pig casting machine.
  • liquid iron becomes from a transport trolley first in a trough-like part of a distributor for collecting of the stream of molten metal, the distributor being poured through a siphon-like wall is divided into two parts, namely a collecting part for the jet of molten metal from the transport container, in which turbulent Current conditions prevail, being in the front part, the one tubular Pour has a soothing of the melt pool occurs.
  • the one in Bottom of this part existing tubular spout can be so close every single ingot recess of the mold can be guided like this the mold edges allow.
  • the device according to the invention is used for Pouring molten metal known construction principles in the Continuous casting of steel like known distribution troughs with adaptation to the special circumstances with a pig casting machine.
  • the device for pouring cast iron in Ingot casting molds 1 comprises in an ingot casting machine one with ingot casting molds 1 equipped endless conveyor belt 2 for transporting the ingot molds from a pouring station 3 to an ingot emptying station, and vice versa, each ingot mold 1 in the casting station 3 as it passes through the casting device with the mold cavity pointing upwards with molten metal is filled from a transport container 4 with a pouring jet 5 over a Guide is introduced into the mold troughs.
  • the guide element is a distributor 6 with a trough-like part 7 for collection the beam 5 of the molten metal from the transport container 4 with formation a storage amount 8, and with a casting 9 with at least one tubular Spout 10 formed, with the release of a communicating lower connection opening 11 in a common siphon-like partition 12 are assigned to each other.
  • the distributor 6 is with its spout 10 at a comparatively short distance arranged above the mold cavity of the ingot casting molds 1. This will make a Spraying of liquid cast iron and thus contamination and damage of the endless conveyor belt 2 of the ingot casting machine avoided.
  • the distributor 6 has a storage amount 8 of liquid metal, in particular Cast iron, must contain, for example, during a change of the transport container 4 or in the event of a fault in the ingot casting machine, a temporary interruption the escape of molten metal from the spout 10 and occasionally an interruption of the metal beam 5 may also be possible.
  • a closure member 13 To this Purpose is associated with the tubular spout 10, a closure member 13. The Closure member 13 has one from above through the melt pool 14 on the Spout opening 10 plug which can be placed on, with a remote control Tripping device 15 is operatively connected.
  • the triggering device 15 is controlled by a control device 16 for monitoring the operation controlled, so that in the event of a business interruption automatically closes the spout 10.
  • the ingot casting machine can preferably have an operational monitoring unit 17, which are associated with the control device 16 of the casting station 3 interacts in such a way that when there is a change or malfunction in the operating state the ingot casting machine a corresponding change in the operation of the Pouring station is initiated.
  • an operational monitoring unit 17 which are associated with the control device 16 of the casting station 3 interacts in such a way that when there is a change or malfunction in the operating state the ingot casting machine a corresponding change in the operation of the Pouring station is initiated.
  • an operational monitoring unit 17 can change the transport speed of the endless conveyor belt 2 a change in the bath height or Storage amount 8 of liquid metal can be set in the distributor 6.
  • the distributor 6 is a device 18 for undisturbed operation assigned to monitor the height of the melt pool 8, which at Exceeding or falling below a predetermined height margin the inclination of the Transport container 4 corrected accordingly. This will make the outflow Cast steel 5 or the amount of molten metal flowing out.
  • 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 used Pouring tubes 10 and the shape of the distributor 6 or its trough-like Part 7 and casting part 9.
  • the device can 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, works.
  • the use of the invention Pouring device is in view of the development of new high performance ingot casting machines essential.
