Thermal Deformation Simulation of Boron Steel Square Sheet in Fluid Cooling Process

The present study was numerically and experimentally investigated on thermal deformation of AC7A and AC4C aluminum alloy used as a casting material for manufacturing automobile tire mold. In this study, temperature distributions of AC7A and AC4C casting material were numerically calculated by finite element analysis (FEA). In order to compare and verify results calculated by numerical analysis, the experiment was carried out on the same condition of numerical analysis. The temperature distribution numerical analysis result revealed that the cooling patterns were predicted almost similar results during cooling process of two casting material. Also, the thermal deformation was calculated from the temperature distribution results. The thermal deformation was closely related to the temperature difference between the surface and inside of the casting.

Although sections of frozen salt solutions have been used as standards for x-ray microanalysis, such solutions are less useful when analysed in the bulk form. They are poor thermal and electrical conductors and severe phase separation occurs during the cooling process. Following a suggestion by Whitecross et al we have made up a series of salt solutions containing a small amount of graphite to improve the sample conductivity. In addition, we have incorporated a polymer to ensure the formation of microcrystalline ice and a consequent homogenity of salt dispersion within the frozen matrix. The mixtures have been used to standardize the analytical procedures applied to frozen hydrated bulk specimens based on the peak/background analytical method and to measure the absolute concentration of elements in developing roots.
