| Abstract: | Comparing with other sand molds,limestone-sand mold is characterized by its severe thermochemical reactions at metal/mold interface in casting process.The importance of looking through the thermal properties of limestone-sand mold is e-mphasized In various respects including casting quality,casting defects and measuring system itself.Using pouring method and singleplate microprocessor for data collection,an experimental installation has been set up and a numerical model d-eveloped for calculating the thermal conductivity k(T)and thermal diffusivity c(T)of limestone sand mold.The calculated results got from present work coincide essentially with the experimental data and this work has not been available so far in literature. |
