Strip casting

In a method of casting metal strip by introducing molten metal between a pair of parallel casting rolls of a twin roll caster via a metal delivery apparatus to form a casting pool of molten metal supported above the nip between the rolls and rotating the rolls so as to cast a solidified strip delivered downwardly from the nip,

• the improvement comprising terminating casting of strip by stopping the flow of metal to the metal delivery apparatus and allowing the quantity of molten metal in the caster to run down to a reduced quantity at which there is still molten metal in the casting pool and continuous strip continues to be cast and then increasing the gap between the casting rolls at the nip by moving at least one of the casting rolls laterally sufficient to interrupt the formation of the strip and to allow downward discharge of said reduced quantity of molten metal through the increased gap between the rolls.
