    摘要： The invention relates to a means of purifying molten metal in a vessel, e.g. a tundish wherein an active inclusion-removing covering layer may be used in a more cost-effective manner. Accordingly, the invention provides a method of purifying molten metal in a molten metal handling vessel (10, 10'), the vessel having an inlet region (A, A') and an outlet region (C, C') for the molten metal, characterised in that the vessel (10, 10') is divided to include a cleaning region (B, B') between the inlet region (A, A') and the outlet region (C, C'), the molten metal (21, 21') is caused to flow from the inlet region (A, A') through the cleaning region (B, B') to the outlet region (C, C') and an active inclusion-removing covering layer (23, 23') is placed on the surface (22, 22') of the molten metal (21, 21') in the cleaning region (B, B').

    摘要： Method and device for opening the outlet of a molten metal handling vessel, comprising a valve (6) having relatively moveable valve parts (7, 9 and 8, 11) and a frangible tube (13) through which gas can be passed, the tube (13) extending through the valve parts (7, 9 and 8, 11) into the outlet (5a) of the vessel, whereby opening the valve (6) by relative movement of the valve parts (9, 11) breaks the tube so that it does not obstruct opening, the end of the tube (13) having a cup-shaped seating portion (13a) to mate with a similarly-shaped recess in or adjacent the valve (6).

    摘要： The invention relates to an improved expendable lining for a molten metal handling vessel and a method of lining the vessel.
    An expendable lining is sprayed inside the vessel and dried and an impregnant coating of greater refractoriness than the expendable lining is applied to the dried expendable lining whereby its permeability is reduced.

    摘要： The invention relates to the removal of unwanted contaminants from a stream of gas, e.g. flue gas.
    A method and an apparatus are provided in which a particulate medium which reacts physically and/or chemically with the contaminant can be introduced into a stream of gas containing the contaminant and the stream can then be passed through a rigid, porous ceramic filter (12) which traps the particulate medium, and with it the contaminant, on the surface of the filter.
