Definitions

  • the invention relates to a vessel for holding liquid steel or cast iron, which in essentially consists of a steel jacket and a lining made of refractory material, an opening provided for tapping is provided at a defined location, according to the preamble of claim 1 and a method for tapping liquid steel or cast iron from a vessel for holding liquid steel or Cast iron according to the preamble of claim 8.
  • the invention has for its object when pouring liquid steel from a suitable container to avoid the flow of slag particles.
  • the opening provided for tapping through a perforated brick be formed.
  • Another embodiment of the invention is that as a means for initiating the Gas-permeable purging stones are arranged in the steel bath.
  • Another embodiment of the invention is that the gas-permeable sinks in Perforated brick itself are arranged.
  • the gas-permeable sink stones around the Perforated stone are arranged around.
  • the perforated stone is offset four from one another by 90 ° Has sink stones.
  • the sink stones are frustoconical.
  • this object is achieved according to the invention by a method according to claim 8, after which at least when falling below a certain remaining amount of liquid steel or Cast iron in the gas vessel against the direction of flow of the liquid steel or cast iron is blown into the vessel.
  • the advantages achieved with the invention consist essentially in that when tapping of liquid steel or cast iron from a suitable vessel does not follow Slag from the steel bath takes place in products intended for further processing, for example billets during continuous casting, mold products. This results in a Quality improvement of the steel or cast iron products produced in this way. Besides, that can Empty the receptacle for holding liquid steel or cast iron higher output than previously with steel or cast iron. Through the complete If the vessel is empty, there is still a cost saving because there is no residual steel or remaining cast iron is dumped into the slag bucket.
  • the invention can Ladles, used in a converter or, for example, in an electric oven.
  • the invention can also be part of sliding closures known per se, in particular in the case of Ladles.
  • frustoconical gas-permeable flushing stones 2 are provided. You have in In the direction of the vessel bottom, connections 6, which are connected, for example, via a ring line 7 can be, which is connected via a connection 8 to the gas supply; - as a gas a gas which is neutral for the steel bath, for example argon, is used.
  • each of the sink stones with a separate connection for the supply must be provided with gas under pressure. It turns out to be advantageous that approximately the same amount of gas flows through all the purging stones, so that a particularly uniform rinsing and therefore a particularly uniform flow of the Steel or cast iron results in racking. If the sink with a ring line pressurized gas can be supplied due to different porosities of the individual sink stones to larger differences in the through the individual sink stones flowing gas quantities come, so that under certain circumstances a more uneven Rinsing results. It has been shown that the gas, for example, advantageously under one Pressure can be from about 10 to 12 bar to achieve an advantageous result.
  • the invention is not limited to the processing of liquid steel; also when parting off cast iron, the invention can be used.
