摘要：
Research, related to possibility of substitution of Al2O3 for SiO2 in metal electroslag remelting, are carried out. the dependence of structure features of melts of the CaF2-Al2O3 and CaF2-SiO2 on composition is studied in the model experiment. The latter is executed by the Monte-Carlo molecular-statistical method. The computations are performed by the semi-empirical quantum-chemical method of MNTOL (modified method of neglect of two-atomic differential overlapping). It is found that the polymerization processes in the CaF2-SiO2 system are intensified at SiO2 content more that 65 molar %.
