The invention relates to non-ferrous metallurgy, to devices for introducing gas into the melt during the refining of metals.
The aim of the invention is to increase the efficiency of treatment of the melt with gases.
FIG. 1 shows the device, a general view; Fig, 2 rotor, vertical section; FIG. 3 is a section; L — A in FIG. 2.
The rotary device for melt processing holds gases with hollow drive shaft I and rotor 2. made in the form of a cylinder.
The rotor 2 is equipped with blades 3, installed symmetrically with its axis of rotation. In the body of the rotor 2, radial holes 4 of a circular section are connected connecting the cavity of the shaft i with the lateral surface of the cylinder of the rotor 2, and the outlet openings of the channels are located between the blades 3.
In the body of the rotor 2, the inclined channels 5 are also filled. The inlets of the rotor 2 are located on the upper or lower bases of the rotor 2, and the pinholes of the rotor 2 coincide with the outlet openings of the channels A.
The angle of inclination of the channels 5 to the horizontal is 10-60 °, and the diameter is 0.5-1.5 cm. The diameter of the radial channels 4 is 0.1-0.4 cm.
The ratio of the height of the rotor cylinder 2 and its diameter is 0.4.
The rotary device is installed, for example, in the casting ladle 6 with the clamp 7, divided into the input and output compartments 8 and 9, respectively. The bucket 6 is equipped with a pouring channel 10 and a filling channel I1,
