Definitions

  • the invention relates to a method for casting a metal belt close to its final dimensions onto a belt casting device provided with a melt receptacle and a conveyor belt, in which a metal melt, in particular made of steel, via a closable, pressurizable pouring chamber and connected via a siphon to a pressurizable main chamber a pouring nozzle flows out.
  • a metal melt in particular made of steel
  • a closable, pressurizable pouring chamber and connected via a siphon to a pressurizable main chamber a pouring nozzle flows out.
  • the invention has set itself the goal of demonstrating a method and the necessary device with which a safe displacement of the air is ensured during the start-up phase.
  • the invention achieves this aim with the features of claims 1 and 4, respectively.
  • the pouring nozzle is filled with liquid melt up to the shut-off located in the area of the mouth.
  • Shut-off devices which allow controlled opening are used, in such a way that at the beginning of the opening there is a slot across the entire width of the pouring nozzle.
  • the casting pressure is chosen so that the melt emerges at high speed during this first slit-shaped opening of the mouth of the pouring channel.
  • the air below the barrier is entrained. This entrainment of the extremely small amounts of air in the region of the mouth of the pouring nozzle is further promoted by the trumpet-like design of the inside of the pouring nozzle facing away from the metal receptacle.
  • the pressure resistance at the mouth of the nozzle increased by obstacles.
  • the elements used for this are preferably self-consuming so that they can later Do not hinder the casting operation.
  • Figure 1 shows schematically the start-up phase.
  • the casting vessel having a main chamber 11 and a pouring chamber 12 is empty, a shut-off element 21 in the pouring nozzle 14 is closed, and the conveyor belt 31 is stationary.
  • the main chamber 11 and the pouring chamber 12 are separated by a wall 13.
  • the casting vessel is filled with melt in such a way that the melt level in the pouring chamber 12 is raised by negative pressure P o and a differential melting level of ⁇ h A is set in the main chamber.
  • the differential level ⁇ h refers to the liquid metal level H that occurs during the casting operation on the conveyor belt or to the inside 16 of the pouring nozzle 14 inclined towards the conveyor belt 31.
  • the conveyor belt 31 is put into operation and the shut-off element 21 is opened in the form of a slot.
  • the liquid metal M emerges from the casting nozzle and is formed into a casting strand 5.
  • the shut-off element 21 is continuously opened during this start-up phase.
  • the differential melting level ⁇ h is reduced until it is brought to the operating level height ⁇ h G.
  • FIGS. 2 to 4 show the lower section of the pouring nozzle 14 with differently configured shut-off elements 21. Shown in section are the mouth 15 of the wall 17 facing away from the main chamber and of the wall 18 inclined towards the main chamber.
  • the inside 16 of the wall 17 is designed like a trumpet. It has a radius R that connects the approximately 45 ° inclined pouring nozzle to the side inclined parallel to the conveyor belt 31.
  • an element 41 is arranged on the wall 17. The element 41 serves to increase the pressure resistance and projects into the space between the conveyor belt 31 and the inside 16.
  • the shut-off element 21 is a knife gate valve 22 designed, which can be moved via a drive 29 is. In the closed position of the knife gate valve 22 this leans against a level 19 in the wall 18.
  • the shut-off element 21 is designed as a flap 23. This leans against a step 19 in the wall 18 in the closed position. In the open position, the flap 23 is pivoted into the wall 17 via a drive (not shown in further detail) such that a plate side forms a plane with the inside 16.
  • a shaft 24 is provided as the shut-off element 21, which has a recess 25 which, according to the rotational position of the shaft 24, releases the pouring nozzle unhindered.
  • the walls 17 and 18 are for thermal purposes Adjust the same wall thickness.
