  • Sampling molten metal
    Patent number: 4296638
    Abstract: A ceramic body includes a disk-shaped mold cavity in its upper part and a slag retention chamber underneath; these chambers are interconnected by a duct extending downward from the bottom of the mold and being continued by a ceramic tube traversing centrally the retention chamber and ending near the bottom thereof. A reversal chamber is excentrically disposed under this tube end, and diametrally thereto ends the feed duct.

  • Device for sampling molten steel
    Patent number: 4291585
    Abstract: A device for sampling molten steel is provided with a mold cavity and an inlet path which includes a floatation-type slag separation chamber. A ceramic sieve is disposed at the outlet of the separation chamber to prevent large slag particles from passing through while trapping small slag droplets by adhesion.

  • Plug connection between a thermo feeler and a holder
    Patent number: 4165995
    Abstract: The connection involves particularly the ends of the leads of thermocouples which are run so that they may engage directly contacts on a socket at the end of a holder. One such lead ends hangs into a central bore of a contact carrier to make contact with a central socket pin. The other or others of the lead ends engage a contact, or contacts in different axial level, and hang out of the contact carrier in the appropriate positions explained in great detail.

  • Apparatus for sampling molten metal
    Patent number: 4148221
    Abstract: A ceramic body has an inlet duct, a mixing chamber for mixing the sampled steel with a steel killing agent; an outlet duct beginning next to the inlet duct port in the lower half of the mixing chamber, leads to a sampling chamber for a pin-shaped sample and is, in turn, connected to a vented chamber for a disk sample.

  • Sampling molten steel
    Patent number: 4102197
    Abstract: A single piece ceramic body has an inlet chamber, an inlet duct and a disc-shaped cavity, that latter cavity is, as far as the body is concerned, of open construction but the opening is closed by a plug. That plug may contain one or two thermo elements, and the inlet chamber may be constructed as an opening with a partitioning sheet or as a duct system with a lateral port and a slag trapping dome. The mold cavity has also venting opening.
