Conclusions

We carried out studies on the chemical segregation during continuous induction melting of the materials of high-magnesia systems.

It was established that the relative length (size) of the zone of columnar grains can be used as a qualitative criterion for evaluating the degree of chemical segregation along the cross section of the ingots obtained by continuous induction melting. Consequently, it was possible to find wider application of induction melting. The applications include the possibility of studying the composition vs property diagrams of the high-temperature engineering systems.

Based on the theory of directional solidification and zone refining as applied to the technology of continuous IMCC process, we obtained the numerical values of the diffusion coefficient of the aluminum and chromium oxides and the impurities in molten magnesium oxide.

A well-founded method (approach) is suggested for selecting the additives that permit one to obtain chemically homogeneous ingots.
