V.N. Shlepakov, S.M. Naumejko

E.O. Paton Electric Welding Institute of the NASU 11 Kazymyr Malevych Str., 03150, Kyiv, Ukraine.

Abstract
Van-Laar theory and Melvin-Hughs methods were the basis to develop the procedure of evaluation of dynamic viscosity of three-component salt-oxide systems. The possibility of preliminary theoretical investigation of the viscosity of slag systems is demonstrated.
Keywords: viscosity, multicomponent slag systems, flux- cored wires, Van-Laar theory, Melvin-Hughs method, slag viscosity, non-associated liquids
