Use of gas dynamic influence on the solidifiable metal of ingots and casts

The experimental findings confirm financial viability of working off the technological process of gas dynamic influence technical and on fusion in a form for casts. Developed and can be used different variants of serve of gas and construction of devices for his input. Physical and mathematical models of the metal hardening process in the sprue device system for gas input were developed. To adapt the model, data of experimental investigations of the process of form heating. The comparative analysis of physics and technological behaviors, and calculation of an amount of gas-making matters is reduced on the basis of lime carbonate and limiting hydrocarbons.
