Metallurgy Calculation Of The Thermodynamic Calculation Software Program Development

Thermodynamic calculation and analysis are the most widely used researchtechniques in metallurgical process as the thermodynamic study needs a lot of data andcomplex thermodynamics calculation. The researchers need to spend a lot of time andenergy to read, collect and organize the relevant data. It provides a basis for thethermodynamic calculation and analysis. Computer can deal with the works which aretedious and relatively simple, so the metallurgy thermodynamics calculation software hasbeen developed for this purpose.The software which is based on the data of thermodynamic data handbook is writtenby process and object oriented programming language Visual c++. The modularmethod has been selected to develop the software. The software which comes with theChinese character environment has a friendly user interface, powerful functions, simpleoperation.. The content of the research includes the following:The software has a built-in thermodynamic database whose data come frominorganic thermodynamic data handbook and the credibility of data can be guaranteed.1)According to the requirements of metallurgical thermodynamics calculation itdetermines the content of the thermodynamic basic data, writing format, effective digitalexpression as well as the unit of measurement, etc and implements the function of addingquering, modifing, and deleting for thermodynamic basic data.2)It designed the material thermodynamics parameter calculation module andintroduced the calculation formula of thermodynamic parameters:enthalpy, entropy, heatcapacity and gibbs free energy. At the same time, the material thermodynamicsparameters calculation processes was determined.3)Chemical reaction thermodynamics calculation module in the standard state wasdesigned. It introduced the thermodynamic parameters of chemical reaction andcalculation formula. The chemical reaction thermodynamics calculation process wasdetermined and it calculated the approximate linear equations between G、lnK and temperature T. At the same time, the corresponding graphics was presented.4)Based on the development and writing of metallurgical thermodynamicscalculation software, the thermodynamics problems in metallurgical process had beenunderstood deeply. It layed a solid theoretical basis for the further development ofmetallurgical thermodynamics calculation software.
