Definitions

  • the invention relates to a method of pouring liquid slag into a foaming bed for foaming the slag by foaming means, for example, water which rises up through jets from the floor of the foaming bed.
  • foaming means for example, water which rises up through jets from the floor of the foaming bed.
  • a troughlike intermediate container 3 is arranged, which extends over the whole width of the foaming bed and into which the slag is conveyed by means of a pouring ladle 4.
  • the intermediate Germany I over the length of the 2 container 3 can be tilted by means of a hand wheel 6. It rests at both ends on traveling mountings, which are displaceable along rails 1, l on the side walls of the pouring bed.
  • the intermediate container 3 On the pouring of the molten slag from the ladle 4 into the intermediate container 3, congealed parts of the slag and iron accompanying it are held back in the ladle. Before the slag can again partially solidify, the intermediate container 3 is rapidly emptied through tilting by means of the hand wheel 6 or of a mechanical impulsion. Since the overflow edge extends over the whole width of the foaming bed, the slag is poured in a wide and fiat stream on to the bed I, so that it distributes itself well over the bed. In order to produce an even quicker distribution, the intermediate container 3 is run on the rails l, pouring bed during the foaming.
  • the invention is however not limited to the intermediate container being displaceable in this manner, and it is also possible for the intermediate container not to extend over the whole width of the pouring bed but only over a part thereof.
  • the intermediate container instead of tilting the intermediate container this can be rapidly emptied in any other way in a wide stream, for example by opening valves. It is also within the ambit of the invention for the slag to be conveyed to the container 3 not by means-of a pouring ladle d but for example by direct discharge perhaps in a channel from the furnace.
  • the speed of tilting of the trough 3 may be regulated according to the viscosity of the slag to be poured.
  • a method of foaming liquid slag on a substantially horizontal foaming bed which comprises; accumulating the liquid slag in a container extending substantially the entire width of the foaming bed, rapidly discharging the container and pouring the liquid slag in a fiat stream over the foaming bed and supplying a foaming agent to the liquid slag through the bottom of the bed.
  • a method of foaming liquid slag on a substantially horizontal foaming bed which comprises; accumulating the liquid slag in a container extending substantially the entire width of the foaming bed, rapidly discharging the container and pouring the liquid slag in a fiat stream over the foaming bed while moving the container in the direction of the length of the bed during the said pouring, and supplying a foaming agent to l the liquid slag through the bottom of the bed.
