Description of the invention (/) The present invention relates to continuous casting of metals. Especially with regard to foundries for the continuous casting of thin metal strips between two moving cooling surfaces, the M & A surface refers especially to those types known as A double-roller casters, and is very particular about the use of To close the side walls of its casting space. [Background of the Invention] To directly cast a thin metal strip with a thickness of several millimeters from liquid metal (for example, steel or copper), it can be obtained from a feed trough in a foundry called " double-roller cast iron " This is achieved by using a pouring nozzle to feed liquid metal. The caster includes a mold in which the inset space is surrounded by a pair of internally cooled rollers on its long sides, the internally cooled roller system having horizontal parallel axes and in opposite directions around its axis Spin. The short sides of the inner cooling roller are closed with a wall plate (called a side wall) made of refractory material and leaning against the flat end of the inner cooling roller. The liquid metal must be solidified only on the cooled cylindrical surface of the roller, and this is achieved by casting connected solidified flakes in the area of the roller gap (that is, the area that minimizes the separation distance of the roller surface). In order to continuously extract from the casting space to form a belt. The roller system can be replaced with a cooling belt with a curved shape for cooling movement. However, in practice, it is difficult to effectively prevent the appearance of a solidified body called an A parasitic solidified layer immediately adjacent to the roller, which is a solidified metal layer generated in a specific region of the side wall. This situation is due to the fact that the liquid metal system adjacent to these areas can exist in a temperature condition that is substantially lower than its nominal temperature, so it can make 4 when contacting the side wall (please read the precautions on the back before filling out this Page > ------ Order --------- Line — Printed by a member of the Intellectual Property Bureau of the Ministry of Economic Affairs, Consumer Cooperatives, Paper Size Applicable + National Standard (CNS) A4 Specification (2) 0 * 297 (Public love) 4 2 5 3 1 9 Α7 ____ Β7 Printed by the Intellectual Property Bureau of the Ministry of Economic Affairs, consumer cooperation Du printed 5. Description of the invention (2) Localized curing. This low temperature situation may be caused by the shadow of the cooling roller ' Either the liquid metal is not allowed to be sufficiently filled in these areas due to the influence of adverse hydrodynamic conditions, or the effect of insufficient side wall temperature due to insufficient pre-heating before casting β Of course, it is also possible It is caused by the combination of several factors mentioned above. Any parasitic solidified body that occurs on the adjacent side of the contact area between the roller and the side wall will cause the side to peel, and this situation will endanger the casting The sealed condition of the space. Then, the metal can penetrate between the side wall and the roller and solidify on it ', and this situation will accelerate the deterioration of the side wall. In most serious cases, the liquid metal is even Possible leakage from the machine, this result will not only harm the foundry itself, but also endanger the operators. In addition, 'when the solid metal derived from this parasitic solidified layer is brought to the bottom of the casting space, its It must pass between the rollers and add another layer of metal thickness β to the thickness in the normal direction of the product. The roller must then immediately absorb an additional force that will cause it to further temporarily separate in order to prevent its deterioration. Therefore, the The quality of the belt is thus adversely affected. The side wall can also be removed, but the attendant hazard is the loss of the foundry's seal. Usually, special injection nozzle structures are tried to limit the appearance of parasitic solidified bodies. These The method is implemented for the liquid metal in the casting space, and the conditions of its flow are assumed to ensure that The metal in the area where the parasitic solidified body is generated can be permanently replenished, for example, by moving the liquid metal leaving the nozzle directly to these areas. However, this situation may cause the amount of liquid metal fed to other parts of the casting space 5 (Please read the notes on the back before filling this page)

Description of the invention (7). As shown in FIG. 2, the outer contour of the coil 11 has a substantially triangular shape so as to conform to the periphery of the casting space defined by the cylindrical outer surface of the roller 1, Therefore, it is possible to prevent the effect of the electromagnetic flux from the coil 11 to heat the periphery of the roller 1. The function of the inductor is to heat and is achieved by the current induced by the electromagnetic flux generated by the coil 11. The heating object is a susceptor Π made of a highly conductive material of graphite. The susceptor 12 is fixed on the back side of the support plate 6 and transmits heat to the plate. The support plate 6 then transmits the heat To this The active part 5 of the side wall 3 is heated so as to reduce the risk of parasitic solidification of the liquid metal when the face of the liquid metal is turned towards the casting space. An insulating material 13 'as an intermediate layer such as a silicon dioxide The base fiber material is used to separate the coil 11 from the susceptor 12 and thus prevent the susceptor 12 from coming into contact with the coil 11 which is cooled by the internal circulating water as previously mentioned. As depicted, The size of the susceptor 12 does not need to be the same as that of the support plate 6 and the active part 5. The susceptor 12 only needs to be placed in the area where the active part 5 where parasitic curing is likely to occur, and the area can be heated preferentially. The copper pipe constituting the coil 11 is extended to the back side of the side wall 3 with two horizontal rigid branch pipes 14 and 15. Hollow bent wires 16 and 17 are fixed to the rigid branch pipes 14 and 15 to communicate with one The current is connected to the inductor device 18, and the inductor is cooled by the water supplied by the wires 16 and 17.

Explanation of the invention ((< =) The main components such as the bodies 9 and 10 and the support 8) are also heated by the electromagnetic flux from the line 11 of the inductor, which must be effective According to the present invention, it is provided with a magnetic field shielding mechanism and an electric field shielding mechanism. A stack of magnetic field screens made of ceramic iron magnets 19 is disposed directly behind the coil 11 to prevent the magnetic field flux from being projected to The coil 11 is arranged behind the coil 11 and transmits the magnetic field flux back to the susceptor 5. In this way, the performance of the device is improved. A cavity 20 is provided in the central region of the stacked ceramic ferromagnet 19 to leave the copper tube portions 21 and 22 with a channel connected to the horizontal rigid branch tubes 14 and 15. The ceramic ferromagnet 19 itself is fixed to a copper plate 23 which is not used to support the ceramic ferromagnet 19 and the coil 11 to provide an electric field screen of the device. The copper plate 23 also cools the back surface of the copper plate by circulating water in the pipe 24. The copper plate 23 is also provided with a cavity 25 through which the copper tube portions 21 and 22 pass. Preferably, as shown in the drawing, the end edge of the copper plate 23 is bent into a circle to form the inclusion. Components of the inductor and insulator 13. Of course, the ceramic ferromagnetic body 19 can also be replaced with any other material capable of achieving its magnetic field shielding function. The horizontal rigid branch pipes 14 and 15 of the copper pipe forming the coil 11 must also pass through the box 7. To this end, a cavity 26 is opened in the box 7. However, in order to prevent the surrounding metal from being heated, and to prevent the measurement data of the various inductors present in the device from being disturbed, it is also necessary to provide effective shielding for rigid branch pipes 14 and 15 of this level. For this purpose, a first copper sheath 27 can be installed in the cavity 26 provided inside the box 7, and in this copper 13 paper size, the Chinese National Standard (CNS) A4 specification (210 X 297 mm) (Please read the precautions on the reverse side before filling out this page) J ---! | Order · ------- _ Line — Intellectual Property Cooperation, Intellectual Property Bureau, Ministry of Economic Affairs, printed 425319 Α7 Β7 V. Description of the Invention (, 丨) {Please read the “Precautions on the back side before filling out this page”) The outer part of the sheath 27 is cooled by a water circulation coil 28. In addition, a second sheath 29 cooled by a coil 30 surrounds the entire portion of the bent wires 16 and 17; because if the shielding effect is reduced, the operation of the side wall 3 will also have a similar risk of interference. A copper ring 31 may be provided as a connection between the two sheaths 27 and 29. The copper ring 31 extends from the first sheath 27 and contacts the second sheath 29 through an articulated link. The articulated connecting rod system includes a ball and socket joint 32 surrounding the second sheath 29 to allow one of the sheaths to move laterally relative to the other sheath. The articulated link must also be able to ensure the electrical connection of the screen. This structure allows the screen to allow the bent wires 16 and 17 to have a degree of freedom of movement, that is, it is possible to cause the bent wires 16 and 17 to follow the movement exerted on the side wall 3 during casting. In order to further increase the degree of freedom of the movement, it is not necessary to surround the single wire-sheath 29 with the bent wires 16 and 17 only, but to connect a series of such sheaths with a hinged link to Surround.

If the susceptor 12 is made of a flammable material such as graphite, it is recommended to blow into the interface between the susceptor 12 and the insulating material 13 such as argon. gas. To this end, a conduit 33 leading to an argon supply and appearing in the interface can be constructed in the box 7. It is also possible to make grooves 34 on the surface of the insulating material 13 in contact with the susceptor 12, so as to improve the circulation effect of argon on the interface. Preferably, in order for the operation of the device to be properly controlled, the temperature of the susceptor 12 should be measured as much as possible. This can be achieved by performing high temperature observations at one or more points. In the example depicted, the Chinese national standard (CNS) A4 regulations (210 X 297 public love) are applied for the paper size 42b3 1 9 A7 ____B7 _ V. Description of the invention (Q) This purpose is in the box 7, The copper plate 23 and the insulating material 13 are made with perforations 35 and 36 so that, for example, optical fibers (not shown) connected to the pyrometer can pass through the perforations 35 and 36 ', which provide two accesses to the back of the sensor I2. The measurement using high-temperature measurement technology in each area can also be replaced by a thermocouple in contact with the susceptor 12, or the two measurement systems are compatible and used to complement the advantages and disadvantages between them. Because thermocouples are fragile, the operation of the pyrometer is susceptible to interference from the surrounding electromagnetic field. The embodiment of the invention depicted in Figure 3 (where common elements in Figures 1 and 2 are identified by the same reference numerals) is different from the previous one in that the sensor via the susceptor is no longer used here The method of heating the active part 5 of the side wall 3 is changed to heat the liquid metal appearing near the active part 5 instead. To achieve this, the susceptor 12 is compared with the versions as depicted in Figures 1 and 2 with perforations 35 and 36 for monitoring it at high temperature and for injecting argon gas. The mechanisms 33 and 34 in the interface between the susceptor 12 / insulating material 13 are omitted. In order for the magnetic field to reach the position of the liquid metal, the dimensions of various parts of the device and the operating parameters of the inductor must be appropriately selected. For this purpose, compared to the previous version, it is necessary to reduce the frequency of the current flowing through the inductor in order to increase the skin depth of the magnetic field; and to reduce the thickness of the insulating material 13 so that The coil 11 can be as close as possible to the liquid metal without endangering the mechanical strength of the refractory material of the side wall 3 while maintaining its thickness. The material used to make the support plate 6 and the active part 5 should have a magnetic field flux of 15 This paper size is applicable to China National Standard (CNS) A4 specifications (210 X 297 public love) (Please read the precautions on the back before filling (This page) Order --------- Line — Printed by the Intellectual Property Bureau of the Ministry of Economic Affairs for consumer cooperation Du printed -1 nt — n _ 4253 1 9 A7 Printed by the Consumers Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs printed B7 V. Invention Note (Q) is as transparent as possible. In general, the use of if refractories with a relatively high electrical conductivity, such as highly graphitized refractory materials or carbides such as carbides, should be avoided. By means of graduations, it can supply the coil 11 of the inductor with a frequency of 1 to 100 kHz at a voltage of 100 to 20,000 volts and a current intensity of 200 to 2000 amps (basically, if the side wall The active part 5 of 3 is heated by a susceptor 12 and has an alternating current of about 30 kHz). If a susceptor 12 is used, it must be heated to a temperature of about 1350 to 1500 ° C. Without departing from the scope of the present invention, modifications can be made to the device previously described in the present invention, but these modifications do not affect the applicability of the inductor by its winding wire 圏 active part 5 of the side wall 3 (at least its The parts that are most likely to be affected by parasitic curing) or the liquid metal itself near the side wall 3, because this situation does not interfere with the operation of other components of the device used to maintain and control the side wall 3. Therefore, it is conceivable to omit the supporting plate 6 so that the active part 5 of the side wall 3 directly contacts the susceptor 12 or the insulating material 13. Similarly, it is also possible to shorten the length of the rigid branch pipes 14 and 15 to a minimum, and to connect the curved wires 16 and 17 to those portions 21 and 22 of the copper coils of the inductor coil 11 extending almost directly. Therefore, it is possible to combine the two shielding sheaths 27 and 29 into a single article. The invention can also be applied in a foundry for casting thin strips located between two mobile cooling belts. 16 paper sizes are applicable to Chinese National Standard (CNS) A4 specifications (210 x 297 mm). ——— — — —-- II-乂 · IJ ί IIII ^-— 111 — — — · ---. {Q first read the notes on the back before filling out this page)
