PURPOSE:To prevent collision of cast pieces with each other, by a method wherein, from a detecting signal for the tail end of a preceding cast piece and a detecting signal for the tip of a subsequent cast piece, a distance between the cast pieces is calculated, and by means of the distance amount, the stop of the subsequent casting piece is controlled. CONSTITUTION:The tail end of a preceding cast piece 2 is detected by an optical detector 19, the tip of a subsequent cast piece 3 is detected by a photoelectric detector 18, and a distance l4 between the two cast pieces 2 and 3 is calculated. The distance l4 is compared with an estimated moving distance l5 between the cast pieces 2 and 3 during a time between output of a stop instruction to a motor 9 and the stop of a roller table 5. When l5 is equal to or longer than l4, the subsequent cast piece 3 is stopped, and when l4 is longer than l5, the cast piece 3 is conveyed as it is. This constitution enables prevention of collision of the cast pieces with each other.
