Abstract
Technical and process features of a flowsheet for fabricating the wire of casting aluminum alloys intended to solder waveguides with the use of the combined continuous casting–pressing of nonferrous metals are considered. The dependences necessary and sufficient to design the constructive elements of equipment and process modes providing the implementation of conditions for the stable run of processes of continuous supply of the metal melt into the stream of the carousel molding laboratory machine, its solidification, and extrusion into the die opening similarly to Conform technology are established. The magnitude of the cross section of the hole in the supply dispenser of the metal melt into the stream of the crystallizer wheel is calculated. The process modes of the continuous casting–pressing using a laboratory installation of a billet 3 mm in diameter and its subsequent treatment by high-quality rolling and drawing in combination with intermediate annealing procedures to the final sizes are presented. According to this flowsheet, a pilot batch of round and square wire of alloys AK12Ts10 and AK12Ts15 has been produced in the amount of 3 kg and delivered to the AO ISS enterprise for industrial test soldering of waveguides.
