The device is to include a cylindrical carrier member for insertion into a tubular lance, also having an overhanging flange on the opposite side thereof being disposed a tapered electrode carrier either a cone with rounded apex or a symmetrical wedge with rounded apex and steep rounded sides.

Device for measuring the level of the interface between a slag layer and

The plug in U.S. Pat. No. 4,165,995 is improved as to the contact carrier by providing slots in an orientation so that thermocouple leads can be laterally inserted before hanging over ridges for contact-making with annular contacts of a socket member in the holder. The orientation of the slots permits lateral placement of the thermocouple leads through the ridges, but the leads will hang over them in a location azimuthally offset from the slot through the respective ridge.

Plug connection between a thermofeeler and a holder

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.

Sampling molten metal

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.

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.

Plug connection between a thermo feeler and a holder

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.

Apparatus for sampling molten metal

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.
