Thermal Properties of Molds Using Various Sands

 · These apparent thermal properties of the dry molds using silica, zircon and chromite sand obtained by pouring steel were much higher than those by aluminum. However, those of the dry olivine sand mold were not influenced by the pouring metal. The thermal conductivity decreased on heating up to about 600°C, but increased at higher temperatures.
