专利摘要:
This invention relates to the refining of aluminum alloys from magnesium with chlorine-containing agents. The purpose of the invention is to increase productivity and reduce maintenance costs. The bucket includes a metal casing 1, a refractory lining 2, an inlet chute 3, | Output chute 4, an internal vertical partition 6 dividing the bucket into the loading compartment 8 and the processing compartment 9, in which the injector 10 is installed. The processing compartment is closed at the base with a horizontal wall 13 The horizontal wall 13 has a hole 14 at its center, the axis of which is aligned with the axis of the injector 10. When the device is operating, the metal from the loading compartment 8 enters the processing section 9 through the hole and there in mixed flow with chlorine iruyuschim gas supplied to injector 10, is purified by magnesium. The ladle allows continuous or intermittent casting. Lightweight refining. There are no restrictions on the choice of injector type.

专利说明:

The invention relates to the metallurgy of aluminum alloys and is aimed at removing magnesium from aluminum alloys by treating the melt with chlorine-containing compounds.
The purpose of the invention is to increase productivity and reduce maintenance costs.
The drawing shows the proposed bucket, a vertical section along the middle longitudinal plane.
The bucket for the chlorination of aluminum alloys has an outer metal body 1, an internal refractory lining 2, an inlet groove 3, an output groove 4 of the metal to be processed 5, an internal vertical partition 6 constituting with the bottom of the bucket a space 7 for metal circulation and separating a bucket on the compartment loading 8 and processing 9. In the latter, a rotor 10 is mounted, driven in rotation by a shaft 11 connected to an engine (not shown) mounted above the shaft 12. The processing section 9 is closed at its base of the horizontal wall 13, which reaches the level of the lower part of the partition and has in its center a hole 14, the axis of which is aligned with the axis of the rotor
In operation, the metal passes into the hole 14 along the trajectory m 15 in the mixed flow mode with the trajectories of gases 16 radially supplied by the rotor. Under the action of a chlorinated gas, magnesium reacts to form liquid magnesium chloride, which collects on the surface of the expanded metal bath, forming a layer 40 at the lower level of the partition, and 17, while the purified metal,
flows out through the outlet chute 4.
Example. A bucket with a usable height of 1 m, having a loading compartment with 1 x 0.15 m dimensions and a machining compartment with 1 x 1 m useful dimensions and equipped with an inlet and outlet grooves allowing operation with: a metal height of 0.80 m Equipped with a horizontal wall with a distance of 0 from the bottom of 0.05 m, made with a central round hole with a diameter of 0.32 m. A rotor with a diameter of 0.32 m, height 0.275 m,. equipped with 136 hole diameters
the wall is with a central hole aligned with the axis of rotation of the rotor.
2. BUCKET POP.1, distinguished by 45 W and with the fact that the cross-sectional area
The holes in the horizontal wall constitute the horizontal section areas of the processing compartment.
3. KoBnf POP.1, characterized in that the horizontal section area of the rotor is approximately equal to the section of the hole in the horizontal wall.
; 6j0015.M and rotating with a speed of 25P rpm, set at a distance of 0.03 m from the wall along the axis of the hole.
An aluminum alloy is continuously fed into this bucket at a temperature that allows it to hold a temperature of 750-80 ° C in the processing compartment.
The results with respect to costs, initial and final contents of magnesium, chlorine consumption and performance are shown in the table.
Consequently, using the proposed bucket with a capacity of about 1 m, it is possible to achieve a processing capacity of the order of 20 tons / hour with an appropriate magnesium removal rate.
