N2 - The filtration of Fe-Si-B melts through a loosely poured filter consisting of corundum granules of diameter 2-3 mm causes a four-fold reduction in the level of contamination from B2O3-SiO2 inclusions with a filter layer height of 2 cm. The refined metal contains almost no inclusions measuring >5 um. A three-fold reduction in the content of solid-phase inclusions of magnesia occurs with the use of a combined filter, consisting of granules and corundum foam filter, but the effectiveness of the melt purification in removing coarse inclusions in this case is low.
