Abstract
In the continuous casting of molten metal, the invention describes a refractory article for reducing deposition of inclusions on a surface contacting the stream of molten metal. The article comprises a first composition and a second composition on at least a portion of the contacting surface. The second composition includes a resin-bonded refractory composition comprising a refractory aggregate and a reactive metal. The resin-bonded refractory composition reduces deposition of inclusions relative to standard carbon-bonded or castable refractories. The second composition is particularly effective as a nose of a stopper rod or a liner for a nozzle, shroud or slide gate plate.
