Purpose of the development: DHA is designed to : · Concentrate significant energy electric arc in a relatively small volume ; · Achieving a more complete recovery elements compared to conventional technologies in electric arc furnaces ; · Implement the regenerative processes in the presence of iron or its oxides , increases the degree of extraction of useful components and increases the effectiveness of the technology . · Recycle and dispose waste metallurgical relatively poor content of basic components for deoxidation purposes , refining, and micro-alloying metal.

Recommended application field: Metallurgy. Scope of DHA: · Refining and modification of iron and steel; · The saturation of iron-(and other) melts restored elements; · Recovery of valuable elements (manganese, chromium, silicon, vanadium, etc.) to dump slag and metallurgical slag whose disposal by conventional technologies is technically difficult.

Technical characteristic:

Advantages over analogues: The main advantages of DHA caused the exception of technological cycle of metal energy and material ferroalloy production, and also allows combine two important final stages of secondary treatment process - refining (deoxidation, alloying) and heating.

The development stage readiness: Ready for application

Description of the development:
()
DEEP RECOVERY arc useful components from STEEL WASTE AND SECONDARY MATERIALS FOR REFINING AND MELT LEGIROVANIYAMETALLICHESKIH .. Technological process of DHA (" arc deep restoration" ) is carrying out the reduction of oxides of elements in the area of plasma arc in the depth of the melt and saturation ( or refining ) restored its elements. Restoring items occurs directly in the depth of the melt processed . Of material in which there are required elements useful (slag , sludge, etc. Refractory bout ) preparing a mixture of ore and reducing consumables and form blocks , fitted to the current supply electrodes . Current is supplied to the electrode and create an electric arc . Doug " burns " in the end of the block cavern configuration close to the hemisphere . The block together with the arc dipped into the melt. Arc gas release zone provides gas-insulated electrode and prevents its closure on the metal. On the surface of the cavity reduction reactions occur . Unit and electrode synchronously spent. recovered items go directly to the metal.
