Definitions

  • the invention is not applicable to the field of metallurgy and electricity, in particular to plasma-induction 5.
  • the low temperature of the slag in these prints is caused by the very principle of the operation of the furnace, in which the electrical unit is in- prised into the electric
  • slags are non-electrical materials, space is not allocated in them and their heating is due to the thermal stability.
  • a plasma arc When supplying food to a food outlet, a plasma arc is ignited between the plasma circuit board and a circuit board with an electronic food contact.
  • the area allocated by the arc does not depend on the density of the download, so that it contributes significantly to the process of melting lightweight.
  • Heating of the slag in such a furnace occurs mainly due to the emission of the arc, which allows it to be heated.
  • - 2 - a significant temperature and raise it above the temperature of the metal.
  • Heated, wide-varying arc slag results in a higher increase in activity, which results in a higher value of 5, which is more expensive.
  • the heated slag starts to actively interact with the fireproof crucible and reduces the service life of the crucible.
