Description of the invention (B) Detailed description The present invention relates to a method for vibrating an ingot mold in a continuous casting equipment, especially a hydraulically driven stroke (reciprocating) device. The mold vibration device is an important component in the continuous metal casting method. It ensures the lubricating effect of the required lubricants, such as foundry powder or oil, and therefore prevents the casting strips from sticking to the ingot mold wall. When the steel is continuously cast, the slag is passed as a lubricant 'through the ingot mold. They are produced by melting the foundry powder, and the method of adding the foundry powder to the tank level surface, so that the foundry powder always covers the tank level surface. The simplest technical solution (which also features the main technical background at the same time) consists in vibrating a continuous casting ingot mold with an eccentric driven by a motor. As a result, the frequency and amplitude of the sinusoidal swing form of the ingot mold can be preset by changing the speed of the motor and the eccentricity of the eccentric wheel. In order for the slag as a lubricant to continuously penetrate the gap between the ingot mold walls of the casting strip and prevent the lubricating film from breaking, the amplitude and frequency of the ingot mold must be adjusted so that the ingot mold moves downwards.

When optimizing the continuous casting process, the selection of vibration parameters is an important part, and it is mainly to choose the best combination of amplitude and frequency. The negative pull must be within a certain limit, generally between 15 and 40%. between. Insignia I --- I--*-----«-1 1 ml In ane n ^ i (Please read the note on the back before filling this page) Use the formula ( The relationship shown in 1) (2) shows that when the ingot mold is vibrating in a sinusoidal waveform, the vibration parameters cannot be arbitrarily combined. The reason for the concept of non-sinusoidal ingot mold movement is to try to make these vibration parameters independent of each other 'so as to influence the process of continuous casting of ingot mold to suit the target. German patent DE 3704793 C2 mentions a travel package ________4_ This paper size is applicable to the China Solid Furniture Standard (CNS) A4 specification (210 × 297 mm) Printed by the Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs 41BB75 V. Description of the invention ( j), with two eccentric shafts, which can be driven to rotate on one stroke of the continuous casting ingot mold or directly pivoted on the stroke. At least one joint shaft (universal joint) is inserted into the rotary drive and eccentric For the joint between shafts, the universal joint meets at least one of the following two conditions: a) the joint head facing away from the eccentric shaft is set in a variable position manner, and D) the joint head is set in a rotatable manner. A non-sinusoidal movement of the ingot mold is caused by a known application of the Kardanfelikr error, which occurs when the cardan joint is misaligned and inserted between the shafts. The non-sinusoidal motion of the ingot mold can be changed by changing the height and moving the rotary drive sideways. In addition, it is mentioned in the specification of German patent DE 3704793 C2 that, on the one hand, the negative pull must be kept as small as possible in order to obtain a stripe-free surface of the stripe. On the other hand, it is advantageous if the strip pull-off curve is tangent to the speed curve of the ingot mold in the region where its slope decreases, which means isotropic time (the time in which the continuous casting ingot mold and the strip move in the same direction) is very good short. However, this causes a long negative pull, which is very unfavorable because it will form a shock mark. The European patent EP 0 1 2 1 6 2 2 B 1 mentions a continuous casting method using an ingot mold supported in a truss frame, which uses an electric hydraulic pressure servo to vibrate. This vibration generating device operates at a frequency (which is higher than the natural frequency of the vibration device itself) based on a preselected vibration amplitude signal generated by a function generator. European patent EP 0 6 1 8 0 2 3 A 1 discloses a continuous casting method in which a paper size of 5 papers with longer side walls and narrower cross walls is used in accordance with Chinese national standard (CNS > A4 size (210 Father 297 mm > ^ — ^ 1 ^^^ 1 ^^^ 1 ^^^ 1 1 ^^ — ^^^ 1 ^^^ 1 ^^^ 1 € JR · ^^^ 1 nn HI an nn \ 1 (Please read the notes on the back before filling out this page) Printed by the Central Bureau of Standards, Ministry of Economic Affairs, Shellfish Consumer Cooperative Co., Ltd. 416375 V. Description of the invention In a certain period of time (during this stage, the difference between the speed of the ingot mold and the strip pull-off speed exceeds a predetermined 将), the side wall of the ingot mold is pulled away from the casting strip by a small lateral distance ', and at the rest of the time (here During the time, the speed of the strip and the ingot mold is about the same.) Then the side wall is brought closer to the casting strip. As this method of alternately widening and narrowing the ingot mold, the amount of tensile force and forging pressure on the strip shell will be 'Reduction' therefore the depth of the vibration mark is reduced and the depth of its corrugated grooves is smaller. EP0618023 also proposes a no-pulling In this case, the slag can intrude into the gap between the strip and the wall of the ingot mold because the ingot mold is alternately widened and narrowed. This is a known sinusoidal and non-sinusoidal velocity. An important point of the trend is that at a predetermined vibration frequency and amplitude, the ingot mold is in each cycle (this period is equivalent to the time between the two times when the strip is pulled by the ingot mold when the ingot wedge moves downward) Have the same speed trend and path trend. "For a thin steel plate program with a steel thickness less than 10 Omm, the casting speed is usually greater than 4 m / min. According to formula (1), the frequency of the reciprocating stroke of the ingot mold is correspondingly high. This frequency reaches the general 値 of negative pull: 40 0 ~ 4 50 strokes / minute. At this high frequency, because of the short period of time, only 0.1 3 ~ 0.1 5 seconds / 7 vibration, so the vibration curve 偏离 sinusoidal shape deviates The degree has almost no effect on the lubricating properties in the ingot mold and the formation of the strip shell. Therefore it is impossible to improve the surface properties of the cast product. The test castings have confirmed this. Therefore, the disadvantages of the conventional non-sinusoidal curve are: Use this The curve can only affect the lubricant _______6 in the range of the low setting speed and low vibration frequency of the ingot mold. ^ _ ^ 1 ^^^ 1 H 1 ^ 1 m 1 ^ 1 m ί \ J (Please read first Note on the back, please fill out this page again) This paper size is applicable to Chinese National Standard (CNS) A4 specification (210X297 gong) Printed by the Central Bureau of Standards of the Ministry of Economic Affairs, Shellfish Consumer Cooperative, 416375 Five 'Invention Description ($) Nature and banding The formation of the shell to improve the quality of the casting product. Therefore, when using the high ingot mold strip pulling speed and vibration frequency for the casting process (such as in the thin steel plate process), a new way must be found. The present invention is directed to this background technology, and its purpose is to use a continuous motion of a casting ingot mold (which is different from all hitherto used), which can be equivalent to a simple sinusoidal or sinusoidal vibration at a comparable frequency and The amplitude controls the thermal transition in the ingot mold and the formation of the strip shell, and improves the quality of the casting product according to the standard. This purpose, a method in the citation of item 1 of the scope of patent application, is achieved by arranging the zero amplitude line of the ingot mold relative to the groove during the casting process at any preset strip pull-off speed. The level is moved up and / or down. By using the present invention, the vibration pattern, frequency, and amplitude of a continuous casting ingot mold can be changed within a wide range in an advantageous manner, or the negative pull and the recovery time and frequency can be optimally adjusted. One feature of the present invention is that when a series of successive ingot molds vibrate, the zero line of the ingot mold is periodically moved upward and downward relative to the position of the mold liquid level surface in the ingot mold. In this way, on the one hand, a sufficiently high pulling frequency can be used to ensure a reliable lubrication effect; on the other hand, a vibration component with a much lower frequency can be introduced into the system "strip of a mold". Amplitude and form, due to the sufficient time, can affect and control the melting ratio of the casting powder, the thermal transition in the area of the tank level surface, and the formation of the strip shell, and greatly improve the quality of the casting product and improve the safety of the operation Sex. According to the present invention, the pull-off speed of the strip is preset in several successive phases. _7_ The paper scale is applicable to the Chinese national standard (CNS ΰ4 specification (210X2? 7mm) I 1 Ϊ-·-I ^ -1.1-^^ 1 ^^ 1---(Please read the note ^^ on the back before filling in this book) Printed by Shellfish Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs 416875 V. Description of the invention ([7) In the individual vibration, the speed trend of the ingot mold is continuously changed to move the zero line of the ingot mold speed. These individual vibrations each correspond to the movement of the ingot mold from one dead point to another dead point and back. A feature of the method of the present invention is to use The superposition of at least two independent vibrations causes the ingot mold to vibrate, and the two vibration systems are distinguished only by using one or a combination of both the velocity trend or the frequency, or the combination of both and the amplitude. In another feature of the present invention The frequency of at least two successive vibrations of the ingot mold is lower than the frequency of pulling the strip when the ingot mold moves downwards. This method can be advantageously more easily implemented in the following manner: Different speed movements and inflows or frequencies and / or The overlapable vibration of the frame 'supports the recording mold in a frame, and sets the frame on the lifter, and the frame and the lifter can be excited to make independent vibrations. This method can be used at least in casting It is used in one and / or several inlaying sections of the process. In this way, the thermal transition in the ingot mold and the formation of the strip shell can be controlled with extreme changes, so the quality of the cast product can be improved according to the standard.

At a vibration frequency of 3 60 strokes / min and amplitude + 3.2 mm, one additional periodical displacement of the zero line of the die mold + 0.8 mm is achieved in the following way: the moment of the maximum speed of the ingot mold is the period when it moves downward In the following two successive vibrations, each decreases by 10 degrees, and in the following two successive vibrations, each increases by ten degrees. Since the example made shows that a small change in the trend of the ingot mold speed (and the effect on the negative pull is not significant) is enough to move the zero line of an ingot mold vibration sufficiently, this displacement is related to its amplitude and The impact of the procedure is traceable. The second to sixth figures show the movement of the ingot mold which can cause almost infinite change, which can be caused by the overlapping of at least two independent vibrations with different vibration parameters. The two upper fields each show two independent vibration parameters, where the trend in the right field is three times more frequent than the trend in the left field. The overlap of these two independent curves results in a path and velocity curve with the underlying field.

Description of the invention (left) In addition, the slag can have a greater cooling effect by overlapping vibrations' In this way, thermal transitions to the ingot mold wall are reduced. The use of these two advantageous effects can avoid the occurrence of depressions on the surface of the strip when casting the stainless Voss field paddle. When using the casting speed and frequency f of 3.8 ~ 4.2 m / min, in 2 4 0 ~ 2 7 0 strokes / min, f 2 2 fi / e = 4 2 ~ 4 5 When testing and casting at 5 strokes / min, the situation of longitudinal depression in the strip can be completely avoided. The signal analysis of the thermal element in the ingot template shows that when the vibration curve of the present invention is used, the heat exchange effect in the area of the tank level surface is much more stable at a lower level. The sixth figure shows another embodiment of the vibration curve of the present invention. This vibration curve has the result that the two parabolic motion trends of the associated amplitude A 1 and person 2 and frequency f: and ί 2 = ί 1/8 overlap. In this case, the speed trend consists of straight sections. The advantage of this curve is that in addition to the above-mentioned positive effects on the quality of the cast product, the measurement is performed by a much smaller number of measurement points, and correspondingly, the programming of the control algorithm takes less effort. -I I ......
