Abstract
A method and an apparatus for enhanced metallurgical processing of molten metal includes an enclosable ladle chamber (23) for reducing the escape of heat during transport of the ladle from a manufacturing vessel such as a furnace (13) to an intermediate processing (15) or refining station or during processing or transport to a receptacle vessel such as a tundish (17). The method comprises introducing a refractory body into the ladle chamber (23), the body having an adjusted specific gravity having a reduced steel ballast to refractory material ratio that is less than required for a specific gravity required to buoyantly support the body in the molten metal. Preferably, the ratio provides a specific gravity greater than the specific gravity required to buoyantly support the body entirely in the slag layer. The method includes enclosing the ladle (22) for example, with a lid (90) and maintaining said refractory body in said ladle until substantially termination of the discharge of the molten metal from the vessel. Preferably, the method also includes intermediate refining such as introducing a balancing composition to the ladle before enclosing. The ratio of steel ballast and refractory material used to achieve the preferred specific gravity may also be adjusted in conjunction with other temperature-resistant or corrosion-resistant changes to the refractory body. For example, high temperature alumina may be used as a refractory material in a higher degree than in previously known bodies, a high temperature cement may be used to join the refractory material and ballast components, and a non-wetting agent made of carbonaceous or siliceous material may reduce deterioration of the body during the extended period of steel and slag contact in the ladle.
