Abstract
The behavior of liquid metal flow and gas pressure of the evaporated styrofoam pattern decomposition by-products inside the mold and surrounding sand for ductile iron was investigated experimentally. A computer aided thermometric and pressure measurement technique was built to study the heat and pressure related processes in the lost foam casting. A complete pattern of temperature/pressure fluctuations is obtained during the rectangular bar casting. A relationship between liquid metal front velocity, mold filling rate, decomposed EPS gases pressure, distance from the gating and mass of decomposed EPS is found.
