Gas Pressure Effect on Sand Collapse in Kinetic Zone of Lost-Foam Casting

Figure 7

Gas pressure at the kinetic zone and temperature in the cast specimen during mold filling. The eight numbers in circles indicate the section between the thermocouple; (a) casting after the actual casting experiment; (b) gas pressure in the kinetic zone; and (c) gas pressure and temperature in the cast specimen during the actual casting experiment.
