Definitions

  • the rotation of the liquid metal in the ingot mold has certain advantages compared to static casting, in particular that of making a favorable modification to the solidification structure by eliminating the basaltic zone in favor of a finer solidification structure.
  • the Fi g. non-limitingly represents a section through a possible embodiment of the system according to the invention.
  • tundish 0 filled with liquid metal and whose tap hole with its adjustable shutter 20 and with its nozzle 8 is located above a mold 1 for continuous casting.
  • the metal M and S. slag to avoid driving past there is provided a nozzle 12 whose ex - Tremite less immersed in the metal M.
  • the ingot mold 1 is provided according to the state of the art with a device 10 for continuously measuring the level of the metal.
  • a device 10 for continuously measuring the level of the metal may conform to that which the applicant has described, for example in his Luxembourg patent LU 80,410.
  • the command 110 which influences the action of the inductor or inductors 11 and 9 is connected, on the one hand, to the control system 100 of a device 10 for determining the level in the ingot mold and, on the other hand, to the metal flow control system 120, i.e. the shutter position adjustment 20.
  • the procedure is as follows: An electromagnetic field is created in the nozzles 12 and possibly 8 with a frequency and a direction of rotation such that the harmful effect of the vortex in the ingot mold is effectively counteracted. The optimal frequency of rotation leading to the desired effect is determined using tests. The direction of rotation of the electromagnetic field in the nozzles is obviously opposite to that of the metal in the mold.
  • the system 100 receives and interprets the data relating to the position of the level of the metal in the ingot mold and transmits them to a unit 200. This unit takes care of the decision whether or not to change the metal feed rate i.e. if it is necessary to change the position of the shutter 20.
  • the unit 200 acts in the affirmative on the control system 120.
  • the unit 200 transmits a signal to the control system 110 which varies the operation of the inductor 11 and possibly inductor 9.
  • This variation in operation can result in an increase in the power and / or the frequency applied to the inductors 9, 11.
  • One of the possibilities for obtaining a quick cleaning is to superimpose the currents d normal supply of inductors for variable duration current pulses.
  • the unit 200 transmits to the system I10 the instruction to resume its mode normal operation.
