Abstract:
PCT No. PCT/EP88/00206 Sec. 371 Date Nov. 17, 1988 Sec. 102(e) Date Nov. 17, 1988 PCT Filed Mar. 16, 1988 PCT Pub. No. WO88/07197 PCT Pub. Date Sep. 22, 1988.A probe for immersion in a bath of liquid metal includes a gas supply pipe closed at its lower end by a stopper which melts in liquid metal, a gas collecting portion having a diaphragm which allows gas to pass but retains liquid metal for collecting the gas bubbling from the supply pipe through the metal, and a gas discharge pipe connected to the gas collecting portion. A gas circuit has one end connected to the gas supply pipe and another end connected to the gas discharge pipe. The circuit includes a gas detector and a pump mounted therein for moving the gas through the circuit. A lance through which the gas circuit extends, includes one portion of a two portion quick-acting coupling and the probe includes the other portion of the coupling. The gas is dried as it circulates in the circuit.
