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.
  • the plasma arc emits the crucible, which further reduces the loss of service life of the crucible.
  • the main part of the crucible is - 3 - in the form of a cooled metal ring.
  • Plasma-induction furnace is, according to the invention, is characterized by a high output due to the increase in the input through the exhaust gas.
  • the invention is further explained by the description of a consumer electronic variant and the accompanying design, which results in a plasma-induced in- duction.
  • the last part of the crucible I, in the vicinity of the disposal of the slag belt 7, is made in the form of a lower metal ring 8.
  • the 8th part is free of the disconnect.
  • a two-way switch is used with the contacts and 8 ” and “ b ” . Cooling the ring of 8 can be freezing, - 4 - Liquid, air or liquid.
  • the ring component is copper, steel, or other metal, which is char- acterized by high heat resistance, and also by low chemical activity.
  • source 9 of food is available, however, alternatively, source 4 and 9 of food are supplied as a single source.
  • the thermistor I is equipped with a hood 10. Otherwise, in the crucible wall I there is a drain II.
  • Plasma-induction furnace operates the following way.
  • alloy 13 is drained through answer II. Intended use
  • Plasma-induction furnace is intended for the smelting of black and non-ferrous metals and alloys.
