ABSTRACT:
A process for casting an ingot from a molten metal by bottom pouring molten metal into an ingot mould is described in which there is located in the ingot mould a bonded flux composition comprising one or more fluxing agents, together with a bonded refractory composition comprising particulate refractory material and fibrous material, the bonded refractory composition being positioned in relation to the bonded flux composition to protect the latter from the initial upsurge of molten metal when pouring commences. The bonded flux composition and the bonded refractory composition can be formed together as a laminate, or the bonded flux composition can be formed with an insert of the bonded refractory composition. Alternatively, the bonded flux composition can be placed on the base of the ingot mould while the bonded refractory composition is placed as a striker pad in a recessed basin in the bottom plate of the mould.
