FIELD: continuous pouring of steel; manufacture of nose part of locking rod or insert of nozzle, protective coat of gate valve plate.
SUBSTANCE: proposed composition has first composition and second composition at section of surface which is in contact with molten metal. Second composition is formed from refractory mixture which contains refractory aggregate, resin-based hardened binder and chemically active metal. Refractory composition by bonded resin makes it possible to reduce deposition of inclusions on surface which is in contact with molten metal flow.
EFFECT: enhanced efficiency.
