An improved integrated system is provided for horizontally-longitudinally cast-forming a continuous length of metal ingot. An ablative material is fed lengthwise and introduced as a lining on a continuous, forwardly moving, heat-resistant flexible belt. The ablative material and the belt are shaped into a composite, forwardly moving, open top, trough-like shape into which molten metal is introduced by a ladle that is rotated at a desired supplying rate. The ablative is charred by the molten metal to provide an initial cooling action on the metal as received and to thereafter protect it and the belt while the composite and the metal are forwardly advanced along a channel-shaped, longitudinally extending, metal ingot-forming, casting station. Molten metal is introduced through a refractory nozzle that is positioned in a spaced relation with respect to the ablative lining of the composite, and back flow of the metal is prevented by a second, backwardly spaced nozzle that is also carried in a spaced relation with respect to the ablative and through which air or a suitable inert gas is supplied under pressure behind the molten metal supply nozzle. Metal is introduced into the nozzle from a pouring ladle which is carried on a turntable-like cradle in such a manner that the rate of pouring can be controlled by turning movement of the ladle. A monitor unit having a roller adapted to engage an upper surface of the metal, as at least partially solidified, has an electrical control for the cradle to select and maintain the feed of the molten metal to provide a desired thickness of the ingot being formed.
