The position of the high temperature portion in the circumferential direction of the pipe is detected, and the cooling fluid supply device is controlled based on the detection result, so that a large amount of cooling fluid is supplied to the cooling chamber of the cooling device corresponding to the high temperature portion of the cast pipe. 1. A horizontal continuous casting device for metal tubes, comprising a control device for controlling the metal tube.
