Abstract
A method for retaining slag in a ladle or similar vessel containing molten metal such as used in the steel industry. Lumps of a highly refractory material having a density between the density of the molten metal and the density of the slag are added to the vessel. As the molten metal is drained from the vessel, the lumps agglomerate around the drain orifice and block the discharge of the slag from the vessel.
