VACUUM LADLE FOR MOLTEN METAL COLLECTION Russian patent published in 2018 - IPC B22D41/00 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy. Vacuum ladle for collecting molten metal contains metal body (1) lined with a refractory material, a lifting arm, removable cover (3) provided with device (4) for connecting the interior of the bucket to the vacuum line, and a device for collecting metal, made in the form of a removable siphon. Siphon consists of external suction pipe (5) and drain pipe (6) located inside the ladle. Drain pipe (6) in the place of contact with the removable cover is made with a spherical surface, and the removable cover in the place of contact with the spherical surface of the siphon is made with a conical surface. Vacuum ladle is equipped with a siphon fixation unit, made in the form of an eccentric clamp, located on a removable cover.

EFFECT: accuracy of the orientation of the suction pipe relative to the location of the metal intake in the cell and the multifunctionality of the bucket are ensured due to the possibility of interrupting the sampling of the metal in the ladle in two ways: overflowing the metal from the bucket through the drain tap and through the siphon.
