-10- ABSTRACT Method of Pouring a Metallic Melt Molten metal is poured from an intermediate vessel 1 into an ingot mound 5 via a sliding gate valve 2 whose sliding plate 6 is moved in the opening or closing direction to maintain the level of the melt in the mould at a predetermined level 9. If there is a partial blockage of the flow passage 3,4, as indicated by the sliding plate 6 performing an opening movement the sliding plate is first moved in the closing direction to throttle the flow of metal through it and thereby reduce the metal level in the mould and is then substantially fully opened to produce a surge of metal through the flow passage to remove the obstruction. Thereafter the valve is again controlled in response to the level of the metal within the mould.
