Analysis of the possibilities of using complex technologies of gas dynamic influence on the melt in the foundry mold

The analysis of the results of theoretical and experimental works, existing technological developments on the use of blowing processes, vacuuming and the use of gas pressure to improve the quality of cast metal of large castings or ingots, showed the prospects of using the specified effects for processing the melt directly in the foundry mold. As a result of a contextual analysis of the operation of devices for squeezing out melt from the siphon pouring system of large castings and ingots and the implementation of intra-mold blowing, as well as the processes of vacuuming and gas dynamic pressure during the solidification of metal in the mold, specific options for their design and corresponding technological features of operation were determined.
