Description

(54) DEVICE FOR COLORED ALLOYS REFINING

This invention relates to the metallurgy of non-ferrous metals and their alloys, in the refinement process.

A device for expanding the molten metal in a ladle is known. The device includes a frame, a hopper with a chute, a rod with a rotating and lifting mechanism, and a gaseous oxidizing agent supply unit. The hollow rod is equipped with a mixing head with rods, and the rotation mechanism is implemented in the form of a reversing frame with three {i-adial protrusions connected with the eccentric drive Cl3.

The disadvantage of this device is the impossibility of refining the melt with flnzh, mixing is not carried out throughout the volume.

It is also known a device for refining non-ferrous alloys, which is a working body rotating in a horizontal plane in the form of a two or three-bladed screw or screw.

hot melt, on which having put a layer of flux 2}.

The disadvantages of the known device include the refining of the noeepXHOCT layer of the melt and the spraying of the flux with a screw.

The purpose of the invention is to increase the efficiency of refining.

This goal is achieved by the fact that in a device for refining vsi & f10 alloys, including a tank for refining the melt, a working member, a drive of the operating member, the latter is filled in the form of two shafts with controllable axes of rotation between each other, a working member of the seasfee flax on shafts through crankshafts with clips.

Fig. 1 shows a device for refining non-ferrous alloys, a common

20 species; in fig. 2 - the same plan view.

On the trolley 1 there is an actuator 2 with a gearbox 3, connected to a persher shaft 4, which is kinematically connected

with the secondary shaft 5 transmission 6. The shafts are installed in the bearings of the uprights 7 and connected to the working body 8 through two cranks 9 and bearings 10. The working body 8 is fixed on the cranks 9c

using clamps 11. The blade of the working body by lowering the crucible 12. The device is protected by a casing 13, under which the time machine 14 is installed for

set refining time.

I The device works as follows.

The working member is lowered into the melt to a predetermined depth and secured with latches. When the drive is operating, the cranks convert the rotational movement into a return postulate and rotational movement of the working member in a vertical plane. With the help of a working body, the flux is kneaded into the entire volume of the melt than 1, the surface of the flux contact with the melt rises, hence the efficiency of refining.
