Description of the invention (ί) The present invention relates to a method and device for continuously casting steel plates, especially thin steel plates, at a relatively high casting speed. An ingot mold that is oscillated periodically, and a belt guide is provided below the ingot mold and has rollers to guide and send out a cast strip, at least some of which are rolled. The son can be driven to rotate on the ground or individually. -In order to send out a casting strip from the ingot mold of a continuous casting facility, several rollers provided below the ingot mold are generally driven by an electric motor. The driving force of the motor must be large enough to ensure a preset uniform strip pull-off speed, taking into account all forces. The various forces related to the forces transmitted from the strip to the driven rollers are mainly the weight of the strip itself, the periodically changing frictional force oscillating in the ingot mold, and the rolling Friction in the sub-bearing, and (if a grill is provided under the ingot mold) the friction of a grill, and bending and bending of the ribbon from the vertical ribbon guide to the horizontal ribbon guide And the force used to overcome the bulging of the strip shell between the rollers. The accuracy of the roller alignment and the temperature of the strip shell (this temperature varies along the length of the strip) have an effect on the above forces. The temperature of the strip shell is particularly related to the casting speed and the temperature of the strip in the cooling chamber below the ingot mold. Related to cooling intensity. In the case of thin steel plate equipment with a funnel-shaped casting area of the ingot mold, the frictional force and the forces used to deform the strip shell in the ingot mold are also taken into consideration when the ingot mold moves up and down. consider. In addition, if the strip is to be reduced in thickness by adjusting the guide rollers, 3 ________ This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm). — ”—.----- installation -------- Order --------- (Please read the notes on the back before filling out this page) 4954〇A7 ______B7 ___ $, invention description (7) must overcome the larger Strength. The number of rolls that can be driven and the way they are set depend on the type of equipment and the concept of the equipment. In the case of traditional continuous casting equipment that has an arc shape and a strip thickness of about 150 to 25 mm, it is generally recognized In order to distribute several roller pairs with oppositely driven rollers over almost the entire arc range and the straight area at the exit of the machine, the pulling force of the strip can be evenly distributed over the length of the strip. The roller driver is designed so that a preset strip pull-off speed in a range can be maintained with the required accuracy and provided with fluctuations. It is used to produce thicknesses up to 150 mm (especially thicknesses of about 30 ~ 1Ό0 mm). Between) thin strip continuous casting equipment is designed in a typical way to The solidification of the strip is achieved in a vertical section that is several meters long, which is directly after the ingot mold. In this section, the strip is guided multiple times with undriven rollers And if necessary, a part of the length is guided through a support grid. To further reduce the thickness, the rollers can be shifted so that they strip the strip (it only solidifies into a shell on the outside, but there are still unsolidified The core) is pressed. At the end of this section (where the strip has completely solidified) there are driven rollers that pull the strip out of the device and bend it at the same time. There are other driven rollers at the end, by which the strip is bent to the horizontal plane and sent out. The oscillation of the ingot mold is an important part of the continuous metal casting process. It ensures that the lubricant (such as casting powder or oil) is required Lubrication, and therefore prevent the strip from sticking to the wall of the ingot mold. In the continuous casting of steel, the slag can be used as a lubricant in the ingot mold. It is caused by the melting of the casting powder, 4 ---. --- L ----- install -------- order --------- (Please read the back first Please pay attention to this page before filling in this page) This paper size is applicable to Chinese National Standard (CNS) A4 specification (210 X 297 mm) 495400 A7 _________B7____ 5. Description of the invention (5) The casting powder is placed on the molten liquid surface in an appropriate manner So that the casting powder always covers the molten liquid surface. (Please read the precautions on the back before filling this page) The simplest technical solution (they are also the mainstream of the background technology) is to use a continuous casting ingot mold The eccentric wheel driven by the motor causes an oscillating movement. In this way, the sinusoidal vibration form of the ingot mold is used, and its frequency and amplitude are preset using the speed of the motor and the eccentricity of the eccentric wheel. If we replace such a drive unit (consisting of a motor, a coupling, and an eccentric wheel) with one or more hydraulic cylinders, the non-sinusoidal waveform of the ingot mold vibration and the change of the stroke height can be used during the casting process. According to the standard affect the lubrication in the ingot mold. In order to allow the slag (as a lubricant) to continuously penetrate the gap between the "casting strip" and the wall of the ingot mold, in order to prevent the lubricant film from breaking, the amplitude and frequency of the ingot mold must be adjusted so that it As it moves downward, it periodically passes through the strip. A vibration period T [in this period, the maintenance process (tiberhole): V s > V. The time component Ts which occurs when the ingot mold moves downward] is generally called "negative! * Strip" and its 値 is: ^ -2 · 8ΐη ~ ι (-— ^ ——)

Description of the invention (ten) T Sn Γ healing = τ is equivalent to this "negative band". At this healing time, the lubricant is in the shell of the band and the The gap between the ingot mold walls is carried in the casting direction. It is known that the "negative band", the heating time, the amplitude and frequency of the oscillation of the ingot mold, and their combination (this combination is set in accordance with the current operating situation) are decisive for the quality of the cast product and must be adjusted To the properties of the molten material to be cast and the cast powder used. When optimizing the continuous casting process, the selection of the oscillation parameters is an important part 'and mainly lies in the selection of the optimal combination of amplitude and frequency. Here, the "negative band" must be within a certain limit, and generally between 15 ~ 40% of an oscillation period can achieve the desired healing time in the range of 40 ~ 200msec using the formula ( The relationship described in 1) and (2) states that 'if a certain healing time is to be achieved, it is impossible to arbitrarily combine the oscillation parameters regardless of the vibration trend of the ingot mold'. For continuous casting equipment with a low casting speed (0.8 to 1.5 m / min), the background art uses a sinusoidal ingot mold vibration, the stroke of which cannot be changed 'and its frequency varies proportionally with the casting speed. In this way, 'making the same distance between the oscillating marks irrespective of the manufacturing speed', this can suppress flaws on the surface of the cast product. Its disadvantages-the healing time varies with the casting speed-can be generally tolerated due to the small range of casting speeds used.

Description of the invention (<) The continuous casting of steel plates is typical), people have tried to make The conventional oscillation parameters known in the traditional continuous casting (Stranggufl) maintain the 'especially the healing time and the distance L between the oscillation marks, so that the traditional continuous casting powder can be used to ensure uniform lubrication and avoid slag and powder. The particles are pulled into the skin of the band formed. In order to prevent the distance between the oscillation marks from exceeding the critical threshold of about 20 sa, the oscillation frequency must be increased in proportion to the casting speed. Therefore, when the ingot mold makes a sinusoidal oscillation, the healing time is greatly reduced. As shown in the third row of Table 1, due to the use of a non-sinusoidal curve, despite the high frequency, sufficient healing time can be achieved. Consider: When the curve trend is different from the sinusoidal shape, the acceleration of the ingot mold must be tolerated much faster. If we increase the casting speed to more than 5 m / min, for example, 8 m / min, as shown in the fifth row of Table 1, the demand will be obtained according to the maximum allowable distance between the oscillation marks, and the frequency will be Causes great acceleration of the ingot mold, and when its mass is about 20 tons, it will cause excessive stress on the components of the equipment and make the entire continuous casting equipment unable to withstand vibration. Studies have shown that when the vibration acceleration of the ingot mold exceeds the gravity acceleration of 9.81 m / s2, due to the large vibration of the equipment and the problem of noise, it is almost impossible to make a casting operation. By using lower frequency mold vibration and larger stroke, the mold acceleration can be reduced. Here we use a state where the acceleration increases with the square of the amplitude and the square of the frequency. It can be clearly seen from the various sine wave vibration curves (Table 1, lines 5 and 6) that in this way, the acceptable acceleration a (below 5 m / s 2) can only use the frequency n 7 This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) I —.—.----- installation -------- order --------- * 511 ^ (Please read the notes on the back before filling in this page) 495400 Table 1 Comparison of oscillation parameters of various casting speeds A7 B7 V.

At these frequencies η, the distance between the oscillation marks L exceeds the critical threshold of about 20, so that it is no longer possible to ensure a uniform and flawless structure on the surface of the strip.

In order to achieve this goal, the method described in the first citation of the scope of the patent application, according to the present invention, will have at least one roller pair with two opposite rollers (the pair of roller pairs At least one of the rollers is driven. 8 This paper size is applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm). ---: ------------ install ------ --Order --------- (Please read the notes on the back before filling in this page) 495400 A7 ____ Β7 ___ V. At least that driven roller except the driven roller rotates In addition to motion, a kind of oscillation that overlaps with rotational motion. Other features of the method of the present invention are found in items 2 to 7 of the appendix to the scope of the patent application. It is particularly advantageous if the periodic up-and-down motion of the rollers is caused by the frequency of the spindle oscillation. In this case, the additional speed of the roller is used to increase the speed of the strip over a period of time (this period is equivalent to the vibration period of the ingot mold) in a period greater than the uniform strip speed, and in another Less than uniform strip velocity in the period. If we match this phase with the additional up-and-down movement of the rollers so that the time with the maximum down speed of the ingot and the time with the minimum stripping speed overlap, then we get a time period for maintenance (T ^ + ΛΤ) In the case of the same strip casting speed, it is larger than the healing time (T *) by one time (ΔT). If we start with the healing time (T required), the initial amplitude of the ingot mold vibration is reduced to be traceable due to the up and down movement of the rollers. This smaller amplitude indicates that the ingot mold speed is smaller. Thus, The acceleration of the mold can be reduced to non-critical. This method can also superimpose the speed of the roller's overlapping up and down movement and / or its amplitude at the same frequency as the speed of the up and down movement of the cycle of the mold or The amplitudes are different. In this way, it is possible to achieve a maximum healing time (T · *) for a preset frequency of the ingot mold oscillation and a preset limit for the acceleration of the strip and the ingot mold. Another feature of the present invention is that, in order to Automatically adjust the liquid level in the ingot mold. Use a signal to adjust the supply of molten iron into the ingot mold.

Description of the invention (also) Department and the The speed of the roller's periodic up and down movement is proportional In addition, the method can be supplemented with the following methods: that is, the speed and amplitude of the periodical up-and-down motion of the overlapping rollers are adjusted to arbitrarily correlate with the speed of the strip and / or the frequency of the spindle oscillation In accordance with the present invention, in an apparatus for carrying out the method, at least one driven roller having at least one roller pair with two opposite rollers (at least one of which is driven) and at least the driven roller and oil can be used. The driving device controlled by the pressure mode cooperates with 'to create a vibration that can overlap with the rotational movement of the driver. It is a particularly advantageous method to control the driving device with signals. These signals are generated by the electronic control means of the oscillation device of the spindle town. Regarding further technical features of the method of the present invention, the roller is connected to a roller holder or a roller bearing, and the roller holder or bearing is designed for a special periodic up and down movement user. If this is not the case, Mode, another mode of the present invention is to fix the roller holder on some parts of the device, and these parts are designed for users who move up and down periodically. The invention can also be applied to some continuous casting equipment, in which the strip changes its thickness by shifting one or more rollers of the roller guide.

Description of invention (β) (Please read the notes on the back before filling this page) Unsupported and support strips (4 ), The rollers (5) and (6) are located at the lower end of the guide, and are used to send out the "casting strip" (4) that has solidified in this area, wherein the roller (5) is driven by a motor. Followed by a section of curve guide (9), which has a plurality of individual and paired rollers (5 ') (5 ") (5"') and (6), which bend the cast bar The belt (4) is deflected from a vertical direction to an arc-shaped conveying direction, and then the belt is bent into a straight direction by the straightening unit (10) and further guided. If necessary, the roller pair, such as (5 '") (6'), can be equipped with a motor driver. A typical operating condition, the casting speed is 4 m / min. According to Figure 2, the oscillation of the ingot mold is shown Sinusoidal trend (10), this trend is caused by the oscillation frequency of 260 strokes / min and the amplitude of 3.4 legs. For this combination of oscillation parameters and casting speed, it results in a healing time of 56.3msec (T healing) and an oscillation mark The distance L between them is 15.4 mm. If we make the rollers (5) (6) do sinusoidal periodic up and down motion (8), the frequency is the frequency of the ingot mode oscillation (2), and the amplitude is 1.7 legs, then The speed trend of the strip is shown in (12). Using this speed trend, the healing time increased by 39%, from (T healing) = 56.3 msec to (T healing + ΔΤ) = 78 · 3 msec. Therefore, a significant advantage of the present invention can be seen from the following points: By synchronizing the rollers (5) and (6) with the ingot mold to periodically move up and down, the healing time is much longer. Thus, the article The lubricating effect of the belt (4) by the molten casting powder is improved to the extent that it can be traced out, so that it can be avoided The occurrence of flaws on the surface. Special emphasis should be placed on increasing the healing time to a traceable level (39% in this case). The rollers (5) and (6) are only applicable to Chinese paper standards on 12 paper sizes.

(Please read the precautions on the back before filling this page) This Another application of the invention is to greatly reduce the amplitude of the ingot mold oscillation when the rollers (5) and (6) oscillate, and to maintain the initial healing time T ☆. In the operating situation shown in Figure 2, By using rollers (5) and (6) to oscillate with an amplitude of 1.7 mm, the amplitude of the ingot mold oscillation can be reduced by 48.2% and from 3.4 mm to 1.76 mm without changing the healing time. At the same ratio The speed (13) and acceleration (16) of the ingot mold (1) and their maximum chirp are reduced. The maximum acceleration of the ingot mold (1) is reduced from 2.52 m / s2 to ι · 30m / s2 This reduction in acceleration can make it easier to build continuous casting equipment, or use a heavier ingot mold, as an example. It is very advantageous when using an electromagnetic brake. Figure 3 shows that at a casting speed of 8 meters / minute and a mold vibration of 448 strokes / minute, 'healing time (T ☆) = 28.3 msec, and the distance between the oscillating marks L = 17.8 mm, where the maximum acceleration of the ingot mold (1) and the bar is 4.0 m / s2 and 5.0 m / s2. If the roller (5) (6) is not driven ) Vibration, the above-mentioned healing time and the distance L between the oscillation mark and the distance between the oscillation mark may only be achieved with some ingot mold speeds. In this case, the maximum acceleration of the ingot mold is 7 · 9 M / s 2. This kind of acceleration will cause a large load on the equipment parts due to the huge mass of the continuous casting ingot mold (about 20 tons), making this casting operation practically impossible. In the example shown in the figure, the oscillation amplitude of the rollers (5) and (6) is 1.8 mm. For example, starting from a 5 ton strip weight, the maximum acceleration of the strip caused by it is 5.0 m / s2, which does not reach the critical threshold. (The strip weight is 13.

Description of the invention (y) • It is caused by a strip thickness of 50 mm, a strip width of 1300 mm and a strip length of 10,000 legs) ° (Please (Read the precautions on the back before filling this page.) The example in Figure 3 shows that the periodic up and down movement of the roller according to the present invention enables continuous casting operations to be performed at high casting speeds. Figure 4 shows that by using the rollers (5) and (6), the non-sinusoidal vibration trend of the periodic up-and-down movement can supplement the advantages of the third figure above due to the longer healing time. If we replace the sinusoidal speed trend of the rollers (5) (6) shown in Figure 3 with the trapezoidal speed trend shown in Figure 4, then the healing time is increased from 28.3 msec to 39.4 msec. That is to say, it is improved by 39%. According to this, another advantage of the present invention can be seen from the following point: 'With the periodic up and down movement of the rollers (5) and (6), a sufficiently long healing time can be achieved. A special advantage of the present invention is that the oscillation of the rollers (5) (6) does not cause the belt to move up and down. This can be seen from the strip movements shown in Figures 5 and 6, which can be traced back to the speed trends of the stripes shown in Figures 3 and 4. In both cases, the strips make an uninterrupted downward motion. 'This motion slows down and accelerates in synchronization with the oscillation of the ingot mold or roller. In addition, if we consider the ingot mold or roller (5) ( 6) The high oscillation frequency 'can eliminate the negative influence of roller oscillation on the stability of the tank level surface. 14 This paper size applies to China National Standard (CNS) A4 (210 X 297 mm)
