Definitions

  • the inventive invention is not available in the area of metals, but in particular it is in the case of devices for the processing of gas and by-products that are not hazardous to small metals.
  • the invention is the most suitable for use in the smelting industry and have become smelted and electrically smelted.
  • the invention may also be found in non-ferrous metals.
  • the device has a "mold lock", which is conveniently secured by the "loading" of the filling machine.
  • Other industrial equipment 'the unit is commissioned with a filling machine with a partial discharge of the discharge of liquid metal.
  • the well-known device ensures a sufficiently high technological indicators of the interaction process.
  • - 2 - a convenient product with a liquid metal is only at a low intensity of the feed rate, which is up to 140 kg / min and longer.
  • the task has been set up to create such devices for the treatment of liquid metal with gases and non-compliant materials.
  • Essential inventions are made in that the process for the processing of liquid metal is used in steelmaking gasses and by-products
  • connection line It is preferable to dispose of a uniform line for the connection through the connection line.
  • the gap between the good outcomes should always be more than 2 sizes, in order to exclude the mutual taxation of the outgoing gas circuits to the other.
  • the angle of impact of the off-gas gas line with the liquid metal ( ⁇ ) will be 40 °.
