FIELD: metallurgy.
SUBSTANCE: the invention is dealt with the field of metallurgy. The device for treatment of liquid metal contains a rotor (9) and is intended for treatment processing treatment of molten metals in a reactor (20) or any analogous device. A gas and-or solid particles are fed into metal mainly through the shaft (8) of the rotor through made in it holes (18) from cavity (16) of the rotor. The shaft (8) passes upward through the base of the reactor (20) with a capability of rotation inside a pipe (3) of a stator. The pipe passes upward from the base of the reactor. The shaft of the rotor and the pipe (3) of the stator are passing through a hole (21) in the lower part of the rotor (9) into a cavity (16) of the rotor. The shaft (8) is fused with the rotor (9) by a fastening tool (13) inside the cavity (16). The pipe (3) of the stator is ended in the cavity (16). The technical result is an increase of service life of the shaft of the rotor, reduction of price of the device.
EFFECT: the invention allows to increase the service life if the shaft if the rotor, to reduce price of the device.
