Definitions

  • the invention relates to a vessel for holding liquid steel or cast iron, which in consists essentially of a steel jacket and a lining made of refractory material, whereby at a defined location there is an opening provided for tapping, whereby um the opening provided for the tapping provided several gas-permeable flushing stones with the help of a gas that prevents hollow vortices when tapping the steel or Cast iron against the direction of flow of the steel or cast iron in the steel bath or Cast iron bath is inflatable, according to the preamble of claims 1 and 5.
  • outlet opening is frustoconical Taper the outlet opening away. This should improve the drainage of the steel become.
  • a single gas-permeable sink is concentric around this outlet opening provided around.
  • the invention is based, for pouring liquid steel from a task for the task suitable vessel to avoid the flow of slag particles.
  • the opening provided for tapping is according to claim 2 through a perforated brick educated.
  • 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 blocks When installed, sink blocks are oriented in their longitudinal direction so that this longitudinal direction intersects the central axis of the opening above this opening.
  • the gas emerges from the surface of the liquid steel or cast iron in the vessel. By blowing the gas, the formation of hollow vortices and the associated entrainment of contaminants can be largely avoided, too if the vessel is at least largely completely emptied.
  • 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 vessel for holding liquid steel or cast iron completely, which is a higher Spreading as previously equivalent to steel or cast iron. By completely idling the vessel still saves costs because there is no residual steel or cast iron more is dumped into the slag bucket.
  • the invention can in ladles, 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.
  • 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 stones 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.
