FIELD: metallurgy.
SUBSTANCE: molten metal purifying and degassing unit has element open for action on molten metal being treated and device imparting rotary motion to molten metal around practically vertical axis. During operation of device, at least part of surface subjected to wear is kept in temporary or constant contact with molten metal. Contacting molten metal is kept in motion relative to surface subjected to wear. Surface subjected to wear is covered with refractory protective coat applied as emulsion which is hardened in heat-resistant binder, inorganic colloidal and/or polymer binder for protection of surface against erosion, oxidation and corrosion. Refractory material is selected from borides of titanium, zirconium, vanadium, tantalum, nickel, chromium, copper and iron or oxides of aluminum, silicon, titanium and other above-mentioned elements or their carbides.
EFFECT: enhanced efficiency.
