Abstract
The apparatus includes a generally cylindrical windscreen member attached to the bottom of a ladle with its axis generally vertical and concentric with a tap hole in the bottom of the ladle through which molten metal flows when released by a valve. An apertured cover plate is telescopically fitted over the windscreen. The cover plate is supported by a wire harness assembly coupled to the underside of the ladle for suspending the cover plate in a hanging relationship beneath the ladle. Lift line apparatus is provided for changing the elevation of the cover plate with respect to the ladle and windscreen in response to changes in the application of tension to the lift line. The cover plate is configured to rest upon, and form a seal with, the upper rim of an ingot mold when the cover plate is lowered while positioned above and aligned with the ingot mold. The windscreen and cover plate are made from a fibrous ceramic low density material to facilitate manual handling.
