  • the principle of the present invention mainly consists in plunging an end portion of a metal tube of predetermined wall thickness to a certain depth into a bath of molten material.
  • the material forming the bath which may be cast iron, steel or even molten glass, will penetrate into the end portion of the tube due to the hydrostatic pressure acting onto the bath surface, and the material in the interior of the tube will be cooled off by heat exchange with the cool tube wall and thus solidify in the tube. If the wall thickness of the tube is sufficiently large, the tube end portion may be maintained in the bath without melting during a time sufiicient to permit the material which has penetrated into the interior of the tube to solidify.
  • the latter is withdrawn from the bath and the tube end portion with the material therein is out off in at least one or a plurality of longitudinally spaced transverse planes to obtain in this way one or a plurality of samples which are representative of the composition of the bath at different levels.

  • the tube according to the present invention may also be surrounded at the outer surface thereof by a sheath of insulating material in order to assure that the tube material is heated up mainly by the material in the bath penetrating into the interior of the tube and not by the bath material surrounding the tube. In this way, the cooling and the solidification of the material penetrated into the interior of the tube is expedited and the time necessary for obtaining a sample reduced so that a series of samples may be quickly anal zed.

  • the apparatus of the present invention provides also great advantages in that the apparatus may be integrated with automatic operations of a metallurgic process.
  • the means for operating a furnace may be properly correlated at the most opportune moments with the operation of taking samples. For instance it is possible to control the openings of port holes of a furnace in such a manner that the port holes are opened at the exact moment the tube is plunged into the bath so that the tube may be plunged through one of the opened port holes into the interior of the bath so that the time the port hole is opened is re claimed to a minimum.
