Definitions
- the present invention relates to the continuous casting of flat metal products, in particular steel. More particularly, the invention relates to the management of the circulation movements of the liquid metal cast in the casting mold by implementing electromagnetic forces in order to improve the quality of the cast products and / or the productivity of the castings. the casting installation.
- flat products are understood to mean slabs, bramettes, thin slabs ... or any other "elongated" cross-sectional format, that is to say the width of which is at least twice that of thickness.
- the ingot molds with which the flat products are cast conventionally comprise two large faces (or walls) of copper or copper alloy, vigorously cooled by circulation of water at their contact, and disposed opposite each other to a distance defining the thickness of the cast product. These full face walls are completed at the end by two small side walls so as to form a sealed casting space reproducing the desired rectangular section.
- a cooling system of the walls, including water chambers and cooling channels, is provided to ensure, via these walls, a heat extraction out of the cast metal sufficient.
- the free surface of the metal cast in the mold (surface which will be designated later by the term "meniscus”, commonly accepted for convenience of language) is generally covered by a slag cover.
- the casting is then carried out using a submerged nozzle, plunging a few tens of centimeters below the meniscus in the mold, and provided at its outlet end lateral openings through which the liquid metal gushes in the direction of small faces of the mold.
- the electromagnetic stirring thus implemented can be done already at the level of the mold itself and / or at the level of the secondary cooling zone of the casting machine.
- a first type (see for example JP 1 228 645 or EP 0750958) consists of a gyratory movement of the molten metal at the meniscus around the casting axis, in order to improve the quality of the surface of the cast products.
- horizontally sliding magnetic fields are applied in the region of the meniscus along the entire width of the large faces of the mold and whose direction of sliding is reversed between a large face and the other.
- a pair of polyphase inductors of planar structure, of the "asynchronous linear motor stator" type is mounted in the upper part of the mold, each inductor developing over the entire width of the large face.
- a second type of stirring recommended is to position the inductors approximately halfway up the mold in order to be able to apply, at the outlet openings of the nozzle immersed this time, a magnetic field sliding along the half-widths of large faces.
- This field is produced by polyphase planar inductors mounted facing the large faces of the mold, this time with two pairs of inductors, one pair per large face, the inductors forming a pair being arranged symmetrically on both sides of the casting axis defined by the nozzle and each covering approximately half a width of the large face.
- the assembly formed by these four inductors is connected to one or more polyphase electrical power supplies that drive everything in coherence.
- the magnetic field produced slides in the opposite direction on the two inductors of the same pair and in the same direction on the inductors of the different faces arranged facing one another on both sides of the cast product.
- EMLA molten metal arriving in the mold by the gills of the nozzle.
- the primary purpose in this case is to promote, or stabilize, a configuration called “double loop” circulation of liquid steel in the mold.
- a “double loop” configuration is particularly favorable for a regular intake of calories in the meniscus region, which naturally tends to cool by heat loss during casting despite the presence of cover slag.
- the magnetic field slides this time inwards, small side faces towards the nozzle therefore, namely against the current of metal jets arriving in the mold.
- the purpose in this case is to "slow down" the metal jets so as to reduce their vigor in order to reduce the meniscus level fluctuations and vortices caused by a too great flow rate.
- the object of the invention is to regulate the electromagnetic stirring mode of the liquid metal over the height of a continuous casting mold of flat metallic products with immersed nozzle with lateral outlet openings directed towards the small walls of the mold, said mold being equipped, on each of its large faces, with a pair of polyphase linear magnetic field inductors sliding horizontally along the width of said large face and disposed on either side of the casting axis; defined by the nozzle, each inductor being connected to a power supply which controls all four inductors coherently, characterized setting
- the inductors being slidably mounted according to the height of the mold, a vertical operating position PB, acting at the outlet openings of the casting nozzle, is passed through vertical translation of said inductors, in which the direction of sliding of the field is reversed between the inductors of the same pair and kept between the two inductors opposite one another on two different pairs, at a high functional position PH, acting at the meniscus of the liquid metal in the mold, in which the field slides in the same direction on the inductors of the same pair and in opposite directions between the two pairs, and vice versa; and in that, during the transition from one functional position to the other, the direction of sliding of the magnetic field of only one of the two inductors of the same pair as well as that of the two inductors is reversed.
- the invention consists, on the basis of an electromagnetic equipment conventionally formed by four horizontal sliding field inductors arranged on either side of the casting axis on each of the large faces of the mold, to be provided
- a mobile assembly of this equipment in the vertical direction that is to say according to the height of the mold (using, for example, worm gear, hydraulic cylinders, rack-and-pinion gears, or any other adapted way)
- a current flipping means at the power supply that makes it possible to reverse the direction of sliding of the magnetic field produced by at least two of the four inductors, one of which is chosen on a large face, the other being then chosen on the other large face in symmetrical position with respect to the casting axis.
- the invention also relates to an electromagnetic stirring equipment for continuous casting mold of flat metal products for the implementation of this method comprising:
- At least one polyphase power supply supplying said inductors and provided with an inverter for at least two of the four inductors;
- FIG. 1 is a general schematic elevational profile of a mold for continuous casting steel slabs equipped with the means according to the invention
- FIG. 2 shows schematically, in a median vertical plane passing through the casting axis and parallel to the large faces of the mold, the two high PH and low PB functional positions of the mobile inductor battery according to the height of the mold. ;
- FIG. 4 is a schematic diagram showing, seen from above the mold, the mode of action of the sliding magnetic field inductors when they are in the high operating position PH;
- FIGS. 5a and 5b respectively show, in a view similar to FIG. 4, the mode of action of the sliding magnetic field inductors when they are in the low functional position PB.
- the implementation of the invention is to allow the inductors to slide vertically along the large face of the mold by changing, at the same time, some of their connections to the power supply to change their brewing action depending on where they are located.
- FIG. 1, representing a mold 1 for the casting of steel slabs 2, generally illustrates the means for implementing the invention.
- this mold comprises two pairs of plates (two large plates 3 and two small 4) copper, or copper alloy, cooled by a vigorous flow of water against their outer surface from a water inlet chamber bottom 20 to an upper water discharge chamber 21.
- the joined and sealed assembly of all of these four plates defines the casting space, elongated rectangular shape.
- An "elongated" shape will be termed a geometry of the casting format whose long sides have a length at least twice that of the short sides.
- the casting space of the mold is supplied with liquid metal by a submerged nozzle 5 centered on the casting axis A and whose upper end is sealed to the bottom opening of a distributor (not shown) placed above at short distance.
- a distributor not shown
- the free low end of the nozzle is provided Lateral outlet openings 17 directed towards the small faces 4. This end conventionally plunges into the mold at a depth of about 15 to 30 cm below the free surface 9 (or meniscus) of molten metal in the mold, or about 25 at 40 centimeters below the upper edge of the copper plates.
- this brewing unit is mounted facing the large faces 3 of the mold. More specifically, this brewing unit is mounted in the niche usually left available between the upper water chamber 21 and the lower water inlet chamber 20, both chambers are in the form of boxes, about twenty cm high each, placed just behind the end portions of the large plates 3.
- the power supply 7 incorporates a converter in order to be able to vary the frequency of the current. It is indeed by the choice of the frequency of the excitation current of the inductors that the sliding speed of the magnetic field produced is fixed. Adjusting the intensity of this current makes it possible to adjust the intensity of the magnetic field.
- the electromagnetic stirring unit 6 comprises a battery of four linear inductors (10a, 10b, and 11a, Hb), preferably identical, of structure of the "asynchronous linear motor stator" type. These are inductors, preferably planes, of conventional technology, with protruding magnetic poles wound vertically elongated and arranged parallel to each other depending on the length of the inductor, which is determined so as to cover approximately one half width of the large plates 3 of the mold.
- the coils surrounding the magnetic poles are advantageously formed by hollow conductors cooled by internal circulation of a cooling fluid, preferably treated water. They thus have their own cooling circuit, independently of that of the ingot mold that accommodates them.
- inductors are about 200 to 300 mm high with regard to their active part (pole faces of the poles), or between 400 and 500 mm overall, given the coil heads that protrude from either side of the poles. .
- the four inductors are grouped pairs by pairs 10 and 11, one pair of inductors for each large face 3 of the mold.
- the inductors of a pair are arranged on either side of the nozzle 5, and the two pairs face each other on either side of the cast product 2.
- the inductors of the same pair are connected remotely one to another (about ten cm) by fasteners 19 to form a mechanically rigid assembly.
- the inductors are movably mounted in vertical translation on the mold.
- conventional displacement means heavy loads, such as hydraulic cylinders, rack and pinion system, mechanical cylinders such as motorized worm 16, etc ... is perfectly possible and even recommended.
- Their amplitude of operation must however be able to allow the displacement of the battery of inductors 6 on 10 or 20 cm, hardly more.
- this relatively low clearance height was sufficient to allow the means of the invention to act with the selectivity required on the liquid metal in the mold as will be seen in more detail later.
- This unit 14 is connected to the power supply 7 to activate the rocker 8 during these translations and thus ensure the necessary reversals of the connections of the windings of the inductors to the phases of the power supply.
- Each inductor producing in effect a magnetic field sliding horizontally over a half width, and only one, of the large faces 3 of the mold, depending on how its electrical connection is arranged, this field will move either outwardly ( from the nozzle to the small face), or inwards (from the small face to the nozzle).
- FIGS. 2 to 5 For the following, reference will be made to FIGS. 2 to 5 in order to have a more complete approach of the means implemented for carrying out the invention.
- a current mold for continuous casting of steel slabs has a length around 900 mm. Its upper 21 and lower 20 water boxes are about 200 mm high. The niche available between them is 500 mm. If the inductors are 400 mm high, this niche is of sufficient size to receive and allow their travel height in a distance of about ten cm.
- the stirring configuration is in the high operating position PH.
- the reference point, middle of the active parts comes to be placed at a height dimension noted PH.
- this active part of the inductors is necessarily shifted downwards relative to the level of the meniscus 9, where the stirring action is then sought, in the high functional position PH, this action is nevertheless effectively felt in the region of the meniscus.
- the inductors (shown in bold dashed lines in FIG. 2) are then connected to the power supply to generate a gyratory movement on the surface of the molten metal around the casting axis A.
- the two inductors 10a, 10b of the same pair 10 generate a sliding field in the same direction (from left to right in Figure 4), so having a uniform brewing effect over the entire width of the associated large face.
- the direction of sliding of the field is reversed from the pair 10 to the other pair 11 on the other large face of the mold.
- the battery of inductors is lowered by 10 or 15 cm downwards, so approximately halfway up the mold or even as far as against the lower box 20 (see Fig. 3a)
- the brewing configuration is in the low functional position PB.
- the electromagnetic stirring is strongly felt at the outlets 17 of the nozzle 5, where it is then sought, although the active part of the inductors is also shifted downwards relative to this level. .
- the inductors are then connected to the power supply 7 so as to generate magnetic fields sliding co-current (FIG 5a) or against the current (FIG 5b) metal jets 18 leaving the gills in the direction of small faces 4 of the mold.
- co-current configuration is synonymous with jet acceleration (EMLA type)
- EMLS type is synonymous with "braking" of the jets.
- the control unit 14 acts on the rocker 8 to invert the electrical phase connection of any two inductors located in axial symmetry with respect to each other. to the nozzle 5, each on a large face 3 of the mold, so as to reverse the direction of sliding of the magnetic field they generate. To do so, it suffices to swap any two phases on all three of a three-phase power supply, or to reverse the direction of the current of a phase in the case of a two-phase power supply.
- the transition from the low position PB to the high position PH sets up a stirring generating an axial rotational movement of the liquid metal in the upper part of the mold.
- the transition from the high position PH to the low position PB gives the operator the choice of assistance with the fresh metal jets from the nozzle, by magnetic linear stirring, the action of which can be carried out in accelerator. jets (Fig. 5a) or jet braking (Fig. 5b).
- the power supply 7 makes it possible to deliver current intensities and adjustable frequencies to values chosen in advance.
- the control unit 14, which is connected to it, can manage this possibility so as to vary the intensity of the applied force.
- EMLA type it is advantageous for the four inductors to exert on the metal a similar force, this configuration is not always desirable for the gyratory movement at the meniscus.
- the two inductors whose field slides against the flow of liquid metal it may be advantageous for the two inductors whose field slides against the flow of liquid metal to provide a greater magnetic force than the others.
- a single drive motor system with chain and sprockets mounted at the end of the screw jacks 12 can replace the described system with individual motors by jacks.
- the electrical conductors forming the coils of the inductors can be full.
- the thermal maintenance of the inductors can in this case be provided by immersion of each pair of inductors in a sealed chamber traversed by a circulation of coolant.
- the invention can be implemented of course, both during the same casting and between two successive castings.
