    This invention relates to the metallurgy of light metals, in particular to processing equipment for the purpose of refining a stream of molten aluminum, magnesium or alloys based on them.
    The purpose of the invention is to increase the purity of the resulting metal and ease of maintenance.
    Figure 1 shows the device, a general view; figure 2 is the same, a longitudinal vertical section; fig.Z the same, a front view with a partial cut; in fig. 4 - treatment agent spreader.
    A device for treating a stream of molten metal or an alloy based on aluminum or magnesium contains platform 1 with set screws 2 for adjusting its horizontal position. The bucket 3 is fixed to the beams 4 by means of i supports 5. The beams 4 are hinged on the supporting elements 6 for rotation around a horizontal axis 7 passing through the drain toe 8 of the bucket 3, and the supporting elements 6 are hinged for turning the frame 9 around the horizon; the dry axis 10. The frame 9 is rigidly fixed on the platform .1.
    The rotation of the beams 4 around the axis 7 and the supporting elements 6 around the axis 10 is carried out by a system of power cylinders 11 and 12 independently of the circle.
    The bucket 3 is made in the form of a metal casing 13 and the lining 14 from the inside, which is in contact with the housing assembly 13, is made of a material with a low heat. conductivity - and the outer part in contact with the melt, of refractory material that does not interact with the melt. The basket 3 is provided with a partition 15 of a mat) with a high thermal conductivity, for example, silicon carbide. Preferably, the partition 15 is removable. The partition 15 divides the capacity of the bucket 3 into two compartments 16 and 17, one of which (compartment 1.6) is connected to the drain toe 8, and the other (compartment
    17) - with chute 18 for supplying liquid metal. The partition 15 is provided with a channel 19 for the flow of metal from compartment 17 to compartment 16.
    The bucket 3 is provided with a removable blade 20,
    made in the form of a metal frame and lining. The part 21 of the lid 20 is hinged to another part 22, in which a hole 23 is made to introduce the atomizer 24 to the treating agent (solid, liquid or gaseous) or a removable thermoelement 25.
    The hinged part 21 of the crust 20 is disposed above, separating 17 the bucket 3 and serves to facilitate access to the surface of the processed melt, for example, when removing slag. Krshka 20 is equipped with a seal 26, which provides sealing of the worker
    spaces so that the gaseous products of refining are removed only through the chute 8 for the supply of liquid metal, which facilitates their trapping.

    Claims (6)
    [1]
     20 is mounted on a bracket 27 connected to a mechanical or hydraulic lifting mechanism (not shown) located in a rack 28 mounted on platform 1. 312 The spreading agent 24 of the processing agent is produced, for example, in the form of a hollow shaft 29 with a fixed on its end {a motor 30 with blades 31, with radial channels 32 connected to the cavity of the shaft 29 and opening an imis between the blades 31, as well as with inclined channels 33, connecting the bottom plane of the rotor 30 with the outlet openings of the channels 32, the Spreader 24 is fixed to the bracket 34 mounted on the stand 35 with the possibility of vertical movement and rotation around the axis of the stand 35. The bracket 34 is symmetrical relative to the stand 35, and on the other A thermoelement 25 is fixed to its end. Racks 28 and 35 are connected by a detachable horizontal beam 36. A device for processing a stream of molten metal or a liquid alloy based on aluminum or magnesium works as follows. The draft metal or unrefined alloy in the form of a melt is fed into the chute 18 either continuously from a smelting furnace or from an intermediate ladle (not shown). After filling the ladle 3 with the melt, if necessary, it is heated by a thermoelement 25, immersing it in. the melt through the opening 23 of the lid 20. Then the thermoelement 25 is lifted on the bracket 34, the latter is turned so that the sprayer 24 of the treating agent appears above the hole 23 of the lid 20. The atomizer 24 is immersed in the melt, lowering it in the bracket 34 as it moves along the rack 35. After immersion of the atomizer 24, the rotation of the rotor 30 is turned on and a refining agent is fed through the cavity of shaft 29. For example, when refining aluminum alloys from hydrogen, such a refining agent can be a mixture of argon with 5% chlorine. As the rotor 30 rotates, the melt is centrifugally sucked into the inclined channels 33 of the rotor 30 and in the outlet openings of the radial channels 32 is mixed with a refining agent. Blades 31 contribute to more intensive dispersion and mixing of the refining agent with the melt. The refined melt is fed either continuously through a drain sock 5-8 for pouring by gravity or, if a portion of the melt is refined, also through the drain sock 8 the melt is poured into the trough of a casting unit (not shown) when the bucket 3 is tilted. a pair of power cylinders 11 around axis 7 (FIG. 2, dashed lines). In this case, Krish 20 is in a raised position (Fig. 3, dash-dotted lines). If it is necessary to clean the bucket 3, repair the lining 14 or replace the partition 15, then the pair of power cylinders 12 rotate the supporting elements 6 around the axis 10. In this case, the bucket 3 takes the position shown by the dash-dotted line (figure 2). If during the refining process it is necessary to remove the slag from the surface of the melt, then part 21 of the crushing unit 20 is raised and the slag is removed with a simple scraper tool. Making a partition 15 of silicon carbide (thermally conductive material) effectively heats the melt with thermoelement 25 in both compartments 16 and 17. The execution of the processing device according to the invention improves the purity of the metal produced (the hydrogen content in the refined aluminum alloy A02104 is 0.10 cm / 100 g of metal). The convenience of maintenance also increases, since the device allows you to quickly and completely drain the melt from the ladle 3. Cleaning and repairs can be carried out outside the casting area (Fig. 2), and slag removal is also facilitated. Claim 1. Device for processing a stream of molten metal or, a liquid alloy based on aluminum or magnesium, containing a ladle with a metal casing and a refractory lining, a partition dividing the ladle into two interconnecting compartments, one of which is made with a chute for supplying liquid metal, and another with an outlet sock with an axis that coincides with the axis of the bucket, means for heating the liquid metal, a sprayer of the treating agent and means for supporting the bucket, distinguishing it from the fact that the purity of the metal and serviceability; the means for supporting the bucket are made in the form of a plate with a frame installed on it and a hinge pivotally connected to one of the frame pillars; the bucket is fixed on the beam with the possibility of rotation around the horizontal axis passing through the outlet sock, moreover, the frame is connected to the platform through the support element with the possibility of rotation around a horizontal axis passing through the support element,
