APPARATUS FOR DETECTING LEAKAGE OF MOLTEN METAL

PURPOSE:To detect the leakage of a molten metal, by arranging a fine pipe made of a low m.p. material to the leakage place of the molten metal and supplying gas having definite pressure to said pipe to detect the pressure or flow rate of said gas. CONSTITUTION:A detection apparatus 1 provided with a...

Zusammenfassung:	PURPOSE:To detect the leakage of a molten metal, by arranging a fine pipe made of a low m.p. material to the leakage place of the molten metal and supplying gas having definite pressure to said pipe to detect the pressure or flow rate of said gas. CONSTITUTION:A detection apparatus 1 provided with a sensor for detecting the change of the pressure or flow rate of gas is connected to a gas source 3 for supplying gas pressure by a small caliber pipe 2 made of a soft low m.p. material such as vinyl plastic or rubber. The gas having definite pressure is always supplied to the detection apparatus 1 from the gas source 3. When a molten metal leaks, the pipe 2 is fused to obtain an output signal P from the detection apparatus 1.
