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.
Claims14
A refractory article for use in the casting of molten metal comprising a first refractory composition comprising a non-resin bonded material and a contacting surface adapted to contact a stream of molten metal, at least a portion of the contacting surface comprising a second refractory composition formed from a resin bonded refractory mixture comprising at least one refractory aggregate, a curable resin binder and a reactive metal selected from the group consisting of aluminum, magnesium, silicon, titanium, and mixtures and alloys thereof, wherein the article has a design ratio of less than eighty percent.
A refractory article for use in the casting of molten metal comprising a first refractory composition comprising a non-resin bonded material and a contacting surface adapted to contact a stream of molten metal, at least a portion of the contacting surface comprising a resin-bonded second refractory composition comprising at least one refractory aggregate and a reactive metal present in sufficient quantity to scavenge oxygen during casting of molten metal.
