A mathematical model and software based on it have been developed to predict the composition and total content of various types of nonmetallic oxide inclusions (NIs) in steel during secondary steel processing. To create the software, the C++ programming language is used in the Visual Studio environment. As a result, the total oxygen content, the characteristic types of oxide NIs, and their content in metal samples taken at various stages of processing in a ladle–furnace unit (LFU) are determined. To validate the developed mathematical model and software, samples of IF-BH steel, K56, 09G2S, and KEI-55 pipe steels, and austenitic corrosion-resistant 08Kh18N10T steel are studied by fractional gas analysis (FGA) and scanning electron microscopy with electron-probe microanalysis. The agreement between the calculated and experimental FGA data is satisfactory, which indicates an adequacy of the proposed mathematical model of NI formation. [ABSTRACT FROM AUTHOR] |
