Definitions
- the invention is available for the purposes of the fire of metals and is intended for the manufacture of metals of a given chemical quantity.
- the most convenient way to heat the metal is by blowing the metal alloy in the furnace bath with various gases, often in the air.
- the process is usually divided into two stages. The first is the reduction of the metal alloy by blowing with the oxidizer for a long time. On the other hand - restoration of the converted metal by the owner. Otherwise, the removal of slags, as well as the restoration, as well as after, is carried out.
- This method is divided into the supply of oxidizing gases for the conversion of the alloy and the internal alloy. The release of the reagent inside the melt is simpler, but much more effective.
- Gas is supplied either through the side of the furnace - below the level of the melt, or through the submerged bodies that supply gas to the bottom of the bath.
- This achieves a more intensive stirring, which goes into the market and more intensive delivery of the molecules of the disperser throughout the whole of the alloy.
- the metal can be delivered through the mix. From the tank with alloy, the metal is supplied to the recess of the tray - 2. The tray is made wide - for the width of the camera.
- the objective of the invention is the fastest delivery of distributors and exporters to a maximum number of recoverable metals.
- the main reason for this is the most complete removal of the available impurities from the metal alloy.
- the main condition for the stability of the proposed process is the thermodynamic equilibrium in the chamber of the angry distillation. Delivered dischargers and solvents should not be heated, but heated, they should be switched off to prevent unnecessary discharging.
- the sum of the heat received with the introduced material and the heat from the oxidation should be no less than the sum of the heat spent during this time.
- the temperature of the material is not less than the temperature of the melting of the refined metal.
- the process of separation is easy to install due to the use of side fume with a variable mode of blowing. Moreover, the pressure in the feeds can also be changed.
