Measurement of thermal properties of sand molds has become the obstacle of developing casting CAD.In this paper,a method of measuring apparent thermal properties of sand molds was provided by pouring method. In order to make the obtained thermal properties more suitable for the purpose of numerical simulation of casting solidification, solidification simulation software was used for the calibration of the thermal properties by sample interpolation method.Finally,the paper showed that the numerical results by...

In order to make the obtained thermal properties more suitable for the purpose of numerical simulation of casting solidification, solidification simulation software was used for the calibration of the thermal properties by sample interpolation method.Finally,the paper showed that the numerical results by using the thermal properties obtained in this method can coincide well with the experimental results.

The corrosion experiments of carbon steels in water at different temperatures in autoclave were performed. Surface analyses with electronic probe and X diffraction were carried out, total iron concentration was measured. All the results show that corrosive rate of carbon steel increases with the raising of temperature of the water. The oxidation rate of iron is less than its dissolve rate in water at 150~250℃. When the temperature is at 250~360℃, the oxidation rate of iron is higher than its dissolve rate in...
