- W1478485588 abstract "The first part of this work offers values for the density and thermal conductivity of silica investment materials as well as silica materials with zircon added. Typically the values range from 0.0010-0.0022 cal/sec cm °C for the silica, and 0.0010 cal/sec cm °C for the silica materials containing zircon. The densities for all materials were about 1.7-1.9 g/cc. The second part develops and analyzes a computer / • program designed to solve for a temperature profile in an investment wall considering mold preheat and metal super heat. It was found that increasing the superheat and preheat extends solidification times and that mold wall thickness determines the means by which heat is removed (i.e „, radiation, convection). Also it was found that the silica plus zircon mold material apparently extends the solidification time of a casting due to the attenuation of radiation through the wail. ' '" @default.
