Аннотация
The interaction of exogenous nanoparticles of refractory compounds Al2O3 and MgAl2O4 with model iron melts containing sulfur as a surfactant is studied. The choice of these nanoparticles and possible variants of sulfur removal from the melt in the form of S2, SO2, and H2S are confirmed by thermodynamic calculations. The dependences of the degree of sulfur removal in the course of the heterophase interaction on the size factors (duration of isothermal storage after the addition of nanoparticles), the type of added nanoparticles, and the sulfur concentration in the model melts are studied. The degree of sulfur removal is 17–32 and 16–35 rel. % upon the introduction of Al2O3 and MgAl2O4 nanoparticles, respectively.
