Abstract

The shut-off device includes (1) a stopper capable of blocking a stream of melt flowing in the guide conduit which introduces the melt from a furnace into a tundish therethrough, if the occasion arises, and (2) a receiving plate disposed below a cooling mold so as to receive a leakage melt and having a heat sensor, the heat sensor being adapted to detect the heat of the leakage melt and communicating with a converter for transmitting an operation signals to the stopper. In such a specially designed structure, if the melt breaks out of the cooling mold, the leaked melt is received by the receiving plate and its heat is detected by the heat sensor. According to the detection of the heat, corresponding electric signals are instantly transmitted from the converter to the stopper and thereby the stopper is actuated so as to block the melt flow in the guide conduit.
