APPLICATION OF COMBINED DIE-CASTING PROCESS IN THE MANUFACTURE OF ALUMINUM WIRE FOR WAVEGUIDE SOLDERING

The study covers technical and technological features of a scheme for wire production from casting aluminum alloys designed for waveguide soldering using combined continuous non-ferrous metal die-casting. Dependencies were found that necessary and sufficient for the design of equipment structural elements and process modes ensuring conditions for a stable process of continuous molten metal feeding into the pass of the laboratory plant rotary crystallizer, metal solidification and extrusion into a die hole, the same as per Conform process. The cross section of a batcher hole for feeding molten metal into the crystallizer wheel pass was calculated. Conditions for ∅3 mm workpiece manufacturing at a laboratory continuous die-casting plant were described, with its subsequent processing to finite size by section rolling and drawing combined with intermediate annealing. A pilot batch of round and square wire made of AK12C10 and AK12C15 alloys in the amount of 3 kg was manufactured under this scheme and transferred to JSC «ISS» named after Academician M.F. Reshetnev for industrial tests in waveguide soldering.
