ABSTRACT:
The invention relates to the provision of an expendable inner lining (13) over the relatively permanent refractory lining (11) of a molten metal handling vessel (10), in which venting means (25) are provided to aid venting and drying of the slurry from which the expendable lining is formed.
Strips (12) of removable material are applied to the surface of the permanent lining (11) and the slurry is applied over the strips and over the remainder of the surface of the permanent lining. After drying of the slurry, the strips (12) are removed to leave vent channels (25).
The removable strips may be of heat-consumable material so that they are destroyed by heating. Alternatively they may be removable and re-usable.
