Abstract
An apparatus for detecting slag outflow when a molten metal covered by molten slag is poured from one vessel to another by receiving the thermal radiation energy at the microwave frequencies emitted from the pouring stream of the molten metal from said one vessel to another to measure a change in thermal radiation energy caused by the difference in the emissivity of the molten metal and of the molten slag is disclosed. The apparatus comprises; a microwave-focusing mechanism which has a focal point at the measuring target point; a waveguide means one end of which is connected to said microwave-focusing mechanism and which receives the thermal radiation energy from said microwave-focusing mechanism; and a radiometer connected to the other end of said waveguide means to measure the thermal radiation energy at microwave frequencies received through said waveguide means.
