MOLTEN METAL SAMPLERS FOR APPLICATIONS WITH HIGH AND LOW OXYGEN CONTENT Russian patent published in 2020 - IPC G01N1/10 G01N1/14 

FIELD: sampling.

SUBSTANCE: group of inventions relates to samplers for sampling from molten metal bath, in particular molten steel bath, for applications with high and low oxygen content. Sampler comprises a carrying tube having a submersible end; sampling chamber assembly located at the submersible end of the carrying tube; an inlet pipe; measuring head and deactivating material arranged along central axis of inlet branch pipe. Sampling chamber assembly comprises a closing plate and a body comprising a submerged end having an opening. Inlet pipe has the first end for reception of molten metal and the second end opposite to the first end, and the second end is interconnected with the specified hole, and the hole is made with possibility of reception of molten metal from the inlet connection pipe. Sampling chamber and the second end of the inlet pipe are at least partially located in the measuring head. At least a portion of the deacidifier material is located near the second end of the inlet branch pipe inside the measuring head. Inlet pipe comprises first connection means arranged at second end of inlet branch pipe, deactivating material contains the second connecting device for interaction with the first connecting facility on the inlet branch pipe with fastening of material-deacidifier in position along the central axis of the inlet connection pipe.

EFFECT: technical result consists in obtaining metal samples, which do not require additional preparation before further analysis, and from which accurate readings on carbon can be taken.
