| Abstract: | An integrated and computerised kinetic database system, intellectualised database management system on kinetics of metallurgy (IDMSKM) is described in this report. IDMSKM has been designed using MS Windows and a Visual C++ and Foxpro hybrid coding technique. It consists of two packages. The ThermoPhysData package has been established for physical property data retrieval and prediction, and presented in a previous publication in steel research. The emphasis in the present paper is placed on the KineticApp package. KineticApp involves G/S, S/S' and G/L' modules for the kinetic prediction, evaluation and analysis of gas/solid, solid/solid and gas/liquid reactions respectively. The key consideration in the module design is to establish the links of the kinetic model and parameters of a reaction system with the system characterisation. Assessed kinetic parameters stored in the database files in KineticApp include the activation energies for some reduction and decomposition reactions, as well as the diffusion in solid oxide systems. Those data are necessary while dealing with the reaction kinetic prediction problems. Several examples regarding the reduction of wustite pellet, the decomposition of CaCO3 and the synthesis of SrTiO3 are illustrated to show the features and functions of G/S and S/S modules. |
