Definitions
- the invention relates to the treatment of liquid metal baths, and more particularly the dispensing devices, in these baths of liquid metals, additives in the form of son.
- the solid or filled wire is initially wound in cylindrical coils on a cylindrical mandrel. It is unwound as and when needed.
- the axis of symmetry of these coils can be either horizontal or vertical.
- a coil of wire is a continuous winding of superimposed layers of contiguous turns.
- the wire is thus wound around a mandrel (for example from left to right).
- the dimensions of this mandrel give the final coil its inside diameter and its width.
- a second layer of turns is wound in the opposite direction of the first bearing on it. The cycle continues until the desired outer diameter for the coil is obtained.
- the winding of the coil ends when the end of the thread of the last turn is on the same face as the origin (face where the winding started).
- the coil In order to maintain this arrangement of turns correctly in place, the coil is generally packaged in a frame, generally metallic.
- the packaging consists of a pallet on which the coil rests and a metal frame that traps the coil. Amounts, for example four in number, come into contact with the last row of outer turns. These are the amounts that hold up the turns of cored wire.
- the reels are unwound from the inside (small diameter) outwards by a reeling installation which initially receives the free end of the first turn wound on the mandrel, so the innermost turn.
- the coils are connected to each other by means of a length of free wire from the last coiled coil. In the case of vertical coils, the two ends are located on the same face to allow the connection, the last outer turn of one being mechanically connected to the first inner turn of the second.
- the unwinding takes place from top to bottom and then from bottom to top for a spool with a vertical axis, or from front to back and vice versa for a coil with a horizontal axis, in accordance with the winding direction of the windings described above.
- the successive unwinding of the rows of turns finally releases the row of outer turns. Once the outer end is reached, if it has been previously connected to the inner end of the next coil, the transition between the coils takes place without intervention. The use is therefore continuous.
- the object of the invention is to propose a solution to this problem of regularity of the unwinding of the last layer of turns of the coil of wire, so as to make reliable the operation of the wire distribution installation at the end of wire feeding. a coil and thus ensure the smooth running of the metallurgical treatment under controlled cost conditions.
- the subject of the invention is an armature for holding a coil of solid or cored wire with an external metal surface for carrying out the addition of substances in a bath of liquid metal by unwinding said coil in said bath , comprising studs enclosing said coil and whose inner faces come into contact with the outermost layer of turns of the wire constituting said coil, characterized in that said inner faces of said uprights comprise, at least over a portion of their length, means tending to intensify the contact between these amounts and the wire by increasing the adhesion between all or part of the turns of the last layer of turns of said wire and the amounts and / or maintenance of all or part of the turns of the last layer of turns of said wire in housings formed on said uprights.
- Said means can be constituted by a layer of material with a high coefficient of adhesion with metals, such as rubber.
- Said means may be constituted by a layer of malleable material deforming in contact with said wire so as to follow the undulations of the outer surface of said turns and thus to define housing for said turns.
- Said material can be selected from rubber, polystyrene, a synthetic foam, polyurethane.
- Said means tending to intensify the contact between the uprights and the wire may be formed by undulations formed on the inner walls of the uprights.
- Said means tending to intensify the contact between the uprights and the wire may be formed by pins provided on the inner walls of the uprights.
- Said means tending to intensify the contact between the uprights and the wire may be constituted by a roughness imparted to the inner walls of the uprights.
- the invention consists in providing on the uprights of the armature which traps the coil means tending to intensify the contact between these uprights and the wire, by increasing the adhesion between the wire and the uprights. and / or blocking said wire in housings formed on said uprights, so as to make it more difficult to lower the turns (for coils with a vertical axis) or the collapse of the turns (for the coils with a horizontal axis).
- This increase in adhesion can be obtained in various ways: by depositing on the surface of the uprights a layer of material increasing the coefficient of adhesion, in other words the friction, between the upright and the wire;
- a soft coating in which the last layer of wire turns can form housings where the wire is inserted during the caging of the coil; these housings then allow to maintain it in its initial position during the reeling;
- FIG. 1 shows a coil of cored wire trapped in its frame
- - Figure 2 which shows schematically in cross section a portion of the last layer of turns of a coil and the amount of a reinforcement according to the prior art in contact with which it is located
- - Figure 3 which shows schematically a first example of implementation of the invention
- FIG. 1 shows a coil 1 of solid or flux-cored wire with a vertical axis whose set of turns is, in addition, kept compact by several substantially longitudinal links surrounding the turns, called circles 2 after removal of the mandrel.
- the number and nature of these bells may vary depending on the type of wire spool.
- These rings guarantee the integrity of the coil winding during the phases of handling and transport of the coil. They are intended to be removed after the coil has been placed in its place of use.
- the wire which composes the coil is wound on a mandrel, during the manufacture of the coil, in several superimposed layers, from the inside to the outside, and each forming a series of turns 3, 4.
- the part initial 5 of the wire emerges from the central part of the coil 1, so as to allow its connection by mechanical means to the end portion of the wire of another coil. It is thus possible to ensure a continuity of the distribution of the wire when a coil has finished unfolding while the metallurgical treatment of the liquid metal is not completed.
- the lower face of the spool 1 rests on a pallet 6, from which four vertical uprights 7, generally metallic, surround the spool 1.
- An unwinding eye 8 permanently connected to the uprights 7 and enclosing the upper face of the coil 1, preferably completes the armature which maintains the coil 1.
- the wire passes through this eye 8 which is generally elliptical as shown, but sometimes circular.
- the eye 8 holds in place all the turns 3, 4 during the injection operations and thus avoids the driving of several turns 3, 4 at a time.
- the small diameter of the ellipse of the eye 8 corresponds to the diameter of the first internal turn.
- each turn 3, 4 is subject:
- Torsion forces are compensated for by the metal casing of the wire (in the case of a cored wire) and can be generally neglected.
- A1 must be equal in absolute value to P + R for the system to be in equilibrium.
- the coefficient of adhesion is of the order of 0.2, that is that is to say that the force A1 resulting from the adhesion between the wire and the amount 7 of the armature is equal to 0.2 x F.
- This is generally insufficient to avoid the collapse of the turns 3, 4 of the last layer of the reel 1 during reeling. In most cases, this collapse of turns causes their entanglement. The reeling must then be interrupted, thereby causing the cessation of the metallurgical treatment.
- the internal faces 9 of the uprights 7 of the armature are modified so as to increase very substantially the friction force A2 between the upright 7 and the turns 3, 4 which are in contact with it.
- the collapse of the turns 3, 4 of the last layer is braked or even completely prevented during their unwinding. They are thus assured of remaining substantially circular and in contact with the uprights 7, so that their unwinding conditions remain stable and that the incidents that have been mentioned can no longer occur.
- this modification of the internal faces 9 of the uprights 7 of the reinforcement consists in coating them with a layer 12 of a compound providing a coefficient of high friction with the metal constituting the outer part of the wire, for example a rubber.
- a coefficient of adhesion of about 1 is observed, or even considerably more. This is sufficient to obtain at least a very significant improvement in the behavior of the turns 3, 4 at the end of unwinding, or even the total suppression of the descent of the turns 3, 4, which maintains their relative provisions during the entire unwinding operation.
- the rubber layer may have a thickness of 0.5mm to 5mm, and the upright 7 may have a width of 10mm to 80mm so that the friction force is exerted on a sufficiently large contact line.
- the number of uprights 7 can be increased from 4 to 6.
- FIG. 4 Another embodiment of the invention, shown in FIG. 4, consists in replacing the relatively thin layer 12 of rubber or the other of the preceding variant with a thicker layer 13 of a malleable material, that is, capable of deforming to conform to the undulations of the surfaces of the turns 3, 4, so that during the conditioning of the coil in the armature, housings 14 for the turns 3, 4 are formed in said material 13 under the effect of the pressure F exerted by the uprights 7 on the coil 1.
- This variant of the invention therefore still more certainly than the previous to prevent the descent of the turns 3, 4, in particular by the fact that the coating-wire contact occurs on the larger areas than in the case of a non-deformable rubber layer.
- the material of the malleable layer may, in particular, be a rubber, or a material having mechanical characteristics similar to those of rubber, polystyrene, a synthetic foam, polyurethane or any other material having malleability properties, under the effect the pressure exerted by the wire and the amount 7, able to perform the functions required by the invention.
- this material also has a high coefficient of adhesion with the thread, so that we also find the features of the previous variant.
- a spool of wire 16mm in diameter having a metric weight of 605g / m, an inside diameter of 800mm, an outside diameter of 1400mm, a height of 1090mm, confined in a frame made of four U-shaped steel 40x20mm and 5mm thick, an EPD M polymer (ethylene-propylene diene rubber) with an acrylic adhesive on one side and features:
- Another variant of the invention is to provide corrugations or pins on the inner surface 9 of the uprights 7, to give it a configuration defining in advance housing for the turns of the wire, so comparable in principle to that it is found in the variant of Figure 4.
- This variant is possible in cases where it can ensure excellent regularity of the winding of the wire, so that the turns are always always facing the housing thus formed to enter without difficulty when setting up the amounts 7 on the pallet 6.
- the invention has been described and shown for the case of a coil 1 with a vertical axis during its unwinding. But it goes without saying that it is easily transposable to the case where the coils have their horizontal axis during their unwinding.
- One of the advantages of the invention is that its implementation does not require any modification to be made to the son known in terms of shapes and / or dimensions.
- the wire has a circular section, but the invention can also be adapted to cases where the wire has a section of other shape, for example, hexagonal or octagonal.
- the means tending to intensify the contact between the uprights 7 and the wire may be arranged on the entire surface of the uprights 7, or only over a portion of their length.
- arranging the means tending to intensify the contact between the uprights 7 and the wire over the entire length of the uprights 7 likely to face the coil 1 may make it possible to maintain the turns 3, 4 of the coil 1 at a distance of constant localization during the entire unwinding of the coil 1, which further ensures the success of the operation.
