| 摘 要： | Based on the mathematical model of Fourier Heat Conductivity Equations, this paper firstchooses an alternating-direction-implicit (ADI) type of finite difference method as the numericalcalculation method which is absolutely convergent and stable for time steps of any size when usedto calculate the temperature field. Then, the generalized programs are designed with FORTRANlanguage which can be used to calculate two-dimensional temperature field of casting solidificationof cast steel or cast iron for any shape. The calculated results about their solidification tendencyobtained from the above programs are found in good agreement with the experimental ones. Inaddition, we have measured the thermal properties of the furane resin sand which is the mouldingmaterial to make steel ingot moulds.

| Abstract: | Based on the mathematical model of Fourier Heat Conductivity Equations, this paper first chooses an alternating-direction-implicit (ADI) type of finite difference method as the numerical calculation method which is absolutely convergent and stable for time steps of any size when used to calculate the temperature field. Then, the generalized programs are designed with FORTRAN language which can be used to calculate two-dimensional temperature field of casting solidification of cast steel or cast iron for any shape. The calculated results about their solidification tendency obtained from the above programs are found in good agreement with the experimental ones. In addition, we have measured the thermal properties of the furane resin sand which is the moulding material to make steel ingot moulds. |
