Abstract (en)
[origin: JPH0211261A] PURPOSE: To obtain a closure device, in which a driving element is not passed through molten metal and a vessel wall by constituting the the rotary and/or the reciprocating driving device as an electromagnetic driving device. CONSTITUTION: The closure device 2 is provided with a ceramic material-made refractory tube 3 as the fixed closure member, and the axis of this tube 3 is vertically stood to the bottom 1. The other ceramic material-made tube 5 is fitted as the movable closure member on the tube 3 and the upper part thereof is closed. Since the tube 5 is rotatably fitted so as not to leak molten metal around the axis of the tube 3, the notched part 4 of the tube 3 and the notched part 6 of the tube 5 are formed as a straight line under opening state of the closure device, and the notched part 6 is covered with the tube 3 at the closing position. The electromagnetic driving device 7 is provided as the rotary driving device for the tube 5. This driving device 7 is provided with magnetic cores 8 of one or plural permanent magnets and one or plural magnetic coils 9. The tube 5 is rotated by supplying the current into the magnetic coil 9 through a connecting lead wire 10.
