    摘要: Molten steel pouring from a ladle into a tundish is surrounded by a vessel which is pressurized to maintain an excess pressure of an inert gas and/or a gas or vapor of a material that treats the steel, e.g., for deoxidizing, desulfurizing and/or other cleansing action. The excess pressure per se inhibits any reoxidation. Reactant material is fed to the chamber at a rate to maintain the excess pressure and/or to ensure sufficient presence of reacting material commensurate with the amount of steel passing through.

    摘要: The particular pipe is provided with a system of blind bores being gas conductively interconnected and an inert gas is fed to this duct and channel system to traverse the gas permeable material of which the pipe is made to emerge particularly from surfaces in contact with molten steel to thereby prevent the precipitation of deposits, particularly on the inside of the pipe, but also on the outside surface thereof where being submerged in the bath of molten steel.

    摘要: An immersion nozzle (2) for metallurgical recipients, in particular for a reservoir arranged upstream of a continuous casting ingot mould, has an interchangeable discharge pipe (2) which can be attached in a leakproof manner on or in a perforated brick (1). To improve the flow conditions and hence the efficiency of the casting, the inlet side of the nozzle comprises an upper elongated section (12) in the form of a tubular shaft (11) which expands conically downward to a given plane and which is narrow in a plane perpendicular to the given plane. A second elongate section (13) ends in an elongated transverse flow section of given dimensions.
