ABSTRACT OF THE DISCLOSURE A process for casting an ingot from n 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 composi- tion being positioned in relation to the bonded flux composi- tion 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. Alterna- tively, 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. - 1 -
