Description

Technical Field

[0001] The continuous casting mold involved in the present invention particularly relates to an adaptive control system for a continuous casting mold applied in the field of continuous metal casting. Background Art

[0002] The continuous casting mold is the core component of a continuous casting machine and is known as the "heart" of continuous casting equipment. Its function is to quickly cool and solidify liquid steel into a billet of a specified shape and ensure the quality of the cast billet and the continuity of production. Its inner wall is usually made of a high thermal conductivity material (such as a copper-based alloy), and the outside is supported by structures such as a water tank and a frame, and is equipped with auxiliary devices such as a cooling water circuit and a lubrication system. However, during the application of existing continuous casting molds, due to uneven cooling of the cast billet, quality problems such as deformation and cracking are likely to occur, which directly affects the casting quality.

[0003] To solve the problem of uneven cooling, a certain continuous casting mold in the market adopts a design that increases the cooling contact area and has a certain market share.

[0004] The specification of Chinese invention patent CN109894585A discloses a continuous casting tube mold. The continuous casting tube mold includes a copper tube and a water jacket; the copper tube is rectangular, and the adjacent sides of the copper tube are smoothly connected through an arc portion; the water jacket is sleeved on the copper tube, and a water gap is formed between the water jacket and the copper tube; it also includes a copper strip arranged on the outer surface of the arc portion along the height direction of the copper tube, and the outer surface of the copper strip is an arc surface and fits closely with the inner surface of the water jacket. By arranging a copper strip on the outer surface of the arc portion of the copper tube along the height direction of the copper tube, on the one hand, the structural strength of the copper tube can be enhanced, and on the other hand, the copper strip can also be closely fitted with the water jacket, so the deformation amount in the middle of the copper tube can be significantly reduced, and the quality of the continuous casting billet produced and the service life of the mold can be improved.

[0005] The specification of Chinese invention patent application CN114939636A discloses a lead ingot continuous casting mold, belonging to the field of continuous casting, aiming to improve the crystallization stability of lead ingots and ensure the quality of lead ingots. It includes a crystallization wheel, and the crystallization wheel is made of a metal material with a thermal conductivity of 30W / mK - 54W / mK. The lead ingot continuous casting mold is made of a metal material with a thermal conductivity of 30W / mK - 54W / mK. Its thermal conductivity is small, and the rate of heat transfer during the crystallization process of lead ingots is reduced, thereby slowing down the cooling rate of lead ingots, making the heat dissipation uniformity better during the crystallization process of lead ingots, the crystallization more stable, effectively avoiding the generation of cracks, and ensuring the quality of lead ingots.

[0006] Although the prior art has alleviated to a certain extent the quality defects such as slab deformation and cracking caused by uneven cooling in the continuous casting mold, there are still the following technical limitations: First, due to the different requirements of casting process parameters and product specifications, the slab size and drawing speed are in a dynamic change state, while the current mold lacks the ability to adjust the cooling intensity and process parameters in real time. This not only weakens the control accuracy of the production process, but also makes it difficult to ensure the quality stability of products. Second, the existing continuous casting mold has not established an effective online monitoring mechanism for the cooling state, and cannot timely detect the abnormal cooling of the slab, resulting in the difficulty of identifying and correcting quality defects in the budding stage, ultimately leading to an increase in the scrap rate and production cost, and seriously restricting the economic benefits of continuous casting production. Summary of the Invention

[0007] In view of the above prior art, the technical problem to be solved by the present invention is the problem that the existing continuous casting mold lacks the dynamic regulation ability for the cooling intensity and key process parameters and has not established an effective online monitoring mechanism for the cooling state.

[0008] To solve the above problems, the present invention provides an adaptive control system for a continuous casting mold, which includes a mold body and a continuous casting mold controller.

A cooling monitoring assembly is arranged in the shaping cooling roller assembly; A cooling monitoring unit is carried in the continuous casting mold controller. The cooling monitoring unit includes a data analysis and processing module. The input end of the data analysis and processing module is connected with a cooling shaping feedback module.

On the other hand, a monitoring mechanism for the slab state can be constructed.

Specific embodiments

[0020] The following describes in detail two embodiments of the present application with reference to the accompanying drawings.

[0021] The first embodiment: Figure 1 - Figure 10 Show a continuous casting mold adaptive control system, including a mold body 1 and a continuous casting mold controller. Cooling circulation systems 2 are arranged at the left and right ends of the mold body 1. A plurality of die orifices 11 communicating with the mold body 1 are fixedly connected to the lower end of the mold body 1. Bending support frames 3 are arranged on the front and rear sides of the lower end of the die orifice 11. A plurality of corresponding sizing and cooling roll assemblies 4 are installed at the closer ends of the two bending support frames 3. A cooling monitoring assembly 6 is arranged inside the sizing and cooling roll assembly 4; The continuous casting crystallizer controller is equipped with a cooling monitoring unit. The cooling monitoring unit includes a data analysis and processing module. The input end of the data analysis and processing module is connected to a cooling shaping feedback module. The output end of the data analysis and processing module is connected to a cooling contact regulation module and a cooling cycle regulation module. The input end of the cooling shaping feedback module is signal-connected to a cooling monitoring component 6. The output end of the cooling contact regulation module is signal-connected to a shaping cooling roller assembly 4. The output end of the cooling cycle regulation module is signal-connected to a cooling cycle system 2. Through the coordinated action of the shaping cooling roller assembly 4, the cooling monitoring component 6, the cooling contact regulation module, and the cooling shaping feedback module, on the one hand, by real-time perceiving the actual state of the billet and dynamically adjusting the crystallization cooling process, the self-adaptive adjustment of the cooling intensity is realized, significantly improving the automation and intelligent level of the mold body 1, ensuring the process control accuracy and the product quality stability. On the other hand, a monitoring mechanism for the billet state can be constructed. By real-time collecting the action parameters of the mold body 1 and the hot state information of the billet, abnormal identification and process correction can be realized when the quality deviation first appears, thus effectively reducing the scrap rate and production cost and improving the economic benefits of the continuous casting production line.

[0022] It should be noted that the cooling cycle system 2 is an existing mechanical mechanism, and those skilled in the art can select it according to actual needs. Here it is directly cited without any change to its principle and structure. For example, the cooling cycle system 2 includes a water tank, a cooling pump group connected to the water tank in a connected manner, and a cooling circulation pipeline. The heat exchange cooling effect on the billet is realized through the cooling circulation pipeline. The cooling circulation pipeline can be preset inside the cooling sleeve 46 or between the cooling sleeve 46 and the support connecting plate 41, or can be arranged on the bending support frame 3, as long as the heat exchange effect can be achieved, and no more details will be described here.

[0023] Figure 3 - Figure 9 It is shown that the shaping cooling roller assembly 4 includes a support connecting plate 41 fixedly installed on the bending support frame 3. Both the left and right ends of the support connecting plate 41 are fixedly connected with telescopic support plates 43. A plurality of driving rollers 45 are connected between the two telescopic support plates 43, and the driving rollers 45 are located on the side of the support connecting plate 41 away from the bending support frame 3. A cooling sleeve 46 is sleeved outside the plurality of driving rollers 45. The cooling sleeve 46 is made of an elastic material and a plurality of copper sheets fixed on the outside of the elasticity, and the cooling sleeve 46 is sleeved outside the driving rollers 45 in an elastically expanded state; One end of the support connecting plate 41 close to the bending support frame 3 extends to the outside of the bending support frame 3 and is fixedly installed with a conveying motor mechanism 42. A driving wheel mechanism 44 cooperating with the conveying motor mechanism 42 is installed at the right end of the right telescopic support plate 43. The driving wheel mechanism 44 is cooperatively connected with the driving roller 45 located on the side close to the bending support frame 3; The output end of the data analysis and processing module is also connected to a driving auxiliary control module. The output end of the driving auxiliary control module is signal-connected to the conveying motor mechanism 42. The cooperation between the driving auxiliary control module and the cooling jacket 46 can, while cooling and shaping the billet, effectively convey the shaped billet, thereby enabling the subsequent adjustability of the cooling effect on the billet, and ensuring the quality of the billet during the cooling and crystallization process.

[0024] It should be noted that both the conveying motor mechanism 42 and the transmission wheel mechanism 44 are existing mechanical mechanisms, which can be selected by those skilled in the art according to actual needs. Here, they are directly cited without any changes to their principles and structures. For example, the conveying motor mechanism 42 includes a motor box fixedly installed on the support connecting plate 41 and the bending support frame 3. A driving motor is fixedly installed inside the motor box. The output end of the driving motor is connected to a bevel gear set, and the bevel gear set is rotatably installed inside the motor box. The transmission wheel mechanism 44 includes a transmission box fixedly installed on the fixed plate 431. A transmission wheel is rotatably connected inside the transmission box. The transmission wheel is fixedly connected to the right end of the transmission roller 45 on the side close to the bending support frame 3. The right end of the bevel gear set is fixedly connected to a driving wheel. A transmission belt is sleeved on the driving wheel and the transmission wheel, which can drive and transmit the transmission roller 45, realize the control of the transmission roller 45, and the rotation of the transmission roller 45 can drive the cooling jacket 46 to rotate outside the transmission roller 45, thereby realizing the conveying and auxiliary function for the billet.

[0025] Figure 5 and Figure 6 It is shown that the telescopic support plate 43 includes fixed plates 431 fixedly installed on the left and right sides of the support connecting plate 41. One end of the fixed plate 431 away from the bending support frame 3 is fixedly connected to a hydraulic telescopic sleeve 433. The hydraulic telescopic sleeve 433 is made of a corrugated elastic material. The deformation direction of the hydraulic telescopic sleeve 433 is perpendicular to the end face of the bending support frame 3. One end of the hydraulic telescopic sleeve 433 away from the bending support frame 3 is fixedly connected to a moving plate 432; One end of the hydraulic telescopic sleeve 433 close to the bending support frame 3 is fixedly connected to a hydraulic branch pipe 434 communicating with it, and one end of the hydraulic branch pipe 434 close to the bending support frame 3 extends outside the fixed plate 431. The output end of the cooling contact control module is signal-connected to the hydraulic mechanism, and the hydraulic mechanism is in a connected and cooperating state with the hydraulic branch pipe 434; The transmission roller 45 on the side close to the bending support frame 3 is rotatably installed between the two fixed plates 431. The transmission roller 45 on the side away from the bending support frame 3 is rotatably installed between the two moving plates 432. And the right end of the transmission roller 45 installed between the two fixed plates 431 extends into the transmission wheel mechanism 44 and is cooperated with the conveying motor mechanism 42 through the transmission wheel mechanism 44; The fixed plate 431 located at the right end is fixedly connected to the transmission wheel mechanism 44. The movable plate 432 located at the right end is in sliding fit with the transmission wheel mechanism 44 through a dovetail chute group. The dovetail chute group includes a dovetail chute opened at the left end of the transmission wheel mechanism 44. A dovetail slider that is in sliding fit with the dovetail chute is fixedly connected to the right end of the movable plate 432, which can realize the functions of limiting and guiding the wire of the movable plate 432 and supporting it. The cooperation between the cooling contact regulation module and the movable plate 432 can effectively realize the regulation of the clamping force exerted by the cooling sleeve 46 on the billet, and further can effectively realize the adaptive regulation of the billet cooling parameters. The cooling parameters of the billet are regulated in the direction of the cooling speed to ensure the quality of the billet. Moreover, during subsequent application processes, it can respectively form a three-party applicability synergy with the cooling temperature and the cooling contact area, further ensuring the self-adaptive regulation effect and improving the regulation effect during the billet cooling process, and promoting the stability of the billet quality.

[0026] It should be noted that the hydraulic mechanism is an existing mechanical mechanism, and those skilled in the art can select it according to actual needs. Here, it is directly cited without any change to its principle and structure. For example, the hydraulic mechanism includes a hydraulic oil tank, a hydraulic oil pump connected to the hydraulic oil tank, a shunt pipe connected to the output end of the hydraulic oil pump, an electric control valve arranged on the shunt pipe, the shunt pipe is connected to the hydraulic branch pipe 434, and the output end of the cooling contact regulation module is respectively in signal connection with the hydraulic oil pump and the electric control valve, which can realize the control of the oil volume in the hydraulic telescopic sleeve 433 and the regulation of the position of the front-side transmission roller 45.

[0027] Figure 7 - Figure 9 It is shown that the cooling monitoring component 6 includes a synchronous support plate 61 fixedly connected between the two movable plates 432, and the synchronous support plate 61 is located inside the cooling sleeve 46. An elastic induction plate 62 is fixedly connected to the side of the synchronous support plate 61 away from the bending support frame 3, and the elastic induction plate 62 abuts against the inner wall of the cooling sleeve 46. An elastic induction cavity is opened in the elastic induction plate 62. A plurality of trigger blocks 63 arranged in correspondence are fixedly connected to the inner walls of the elastic induction cavity on the side close to the bending support frame 3 and the side away from the bending support frame 3. The input end of the cooling and shaping feedback module is in signal connection with the trigger blocks 63. The cooperation between the cooling and shaping feedback module and the trigger blocks 63 can effectively establish a mechanism for monitoring the cooling state of the billet, effectively realize the data monitoring function in the initial stage of billet cooling, and then cooperate with the data analysis and processing module to identify abnormalities at the budding stage of billet cooling quality defects, as well as the subsequent timely and effective correction function, effectively reducing the rejection rate, reducing production costs, and promoting the economic benefits of continuous casting.

[0028] Figure 1 and Figure 2It is shown that the input end of the data analysis and processing module is also connected to a casting parameter acquisition module and an interactive instruction receiving module, and the input ends of the casting parameter acquisition module and the interactive instruction receiving module are both connected to the continuous casting control platform signal; The output end of the data analysis and processing module is also connected to the cooling crystallization data display module and the abnormal warning module. The output ends of the cooling data display module and the abnormal warning module are both connected to the continuous casting control platform signal. The output end of the abnormal warning module is also connected to the alarm signal set on the continuous casting crystallization controller. The cooperation of the casting parameter acquisition module, the interactive instruction receiving module, the cooling crystallization data display module and the abnormal warning module can further promote the cooling monitoring unit to act on the crystallizer body 1. The accuracy of the self-adaptive control of the ingot parameters, ensure the effectiveness of the self-adaptive control, promote the intelligent function of the crystallizer body 1, and can also effectively realize the interaction with technical personnel to ensure the controllability of the continuous casting process.

[0029] Figure 1 , Figure 2 and Figure 10 It is shown that a plurality of corresponding guide rollers 5 are installed at one end close to the two bending support frames 3, and the guide rollers 5 are spaced apart from the shaping cooling roller assembly 4. The input end of the data analysis and processing module is also connected to the crystallization conveying data acquisition module. The input end of the crystallization conveying data acquisition module is connected to the signal of the speed collector arranged in the guide roller 5. The cooperation between the crystallization conveying data acquisition unit and the guide roller 5 can, on the one hand, realize the continuous guiding effect on the ingot and ensure the effectiveness and accuracy of the cooling and transmission of the ingot, and on the other hand, can verify the control data of the shaping cooling roller assembly 4, and then can assist the data analysis and processing module to judge the effectiveness of the control execution and realize the self-checking effect of the execution of the control instruction, so as to ensure the effectiveness and reliability of the subsequent data control.

[0030] Figure 1 - Figure 10During the application process of the mold body 1, the casting parameter acquisition module in the cooling monitoring unit collects continuous casting parameters through the continuous casting control platform, and transmits the collected data to the data analysis and processing module after conversion. The continuous casting parameters include, but are not limited to, relevant parameters such as casting temperature, molten metal flow rate, billet size, cooling data, and casting properties. The interaction instruction receiving module receives the control instructions for continuous casting through the continuous casting control platform and then transmits them to the data analysis and processing module. After receiving the data transmitted by the casting parameter acquisition module and the interaction instruction receiving module, the data analysis and processing module controls the cooling circulation system 2 through the cooling circulation regulation module respectively, so that the cooling circulation system 2 starts to work and cools down the mold body 1. The conveying motor mechanism 42 is controlled through the driving auxiliary regulation module, so that the conveying motor mechanism 42 starts, and the driving roller 45 is driven to rotate through the transmission wheel mechanism 44, so that the cooling sleeve 46 rotates continuously and can effectively act on the billet. In addition, the hydraulic mechanism is controlled through the cooling contact regulation module. The hydraulic mechanism acts on the hydraulic telescopic sleeve 433 through the hydraulic branch pipe 434, and controls the internal pressure by inputting or outputting hydraulic oil. When a certain amount of hydraulic oil is input into the hydraulic telescopic sleeve 433, the length of the hydraulic telescopic sleeve 433 will be extended, so that the hydraulic telescopic sleeve 433 drives the moving plate 432 to move away from the bending support frame 3, thereby reducing the gap between the two corresponding retractable support plates 43. When a certain amount of hydraulic oil is output from the hydraulic telescopic sleeve 433, the length of the hydraulic telescopic sleeve 433 will be shortened, so that the hydraulic telescopic sleeve 433 drives the moving plate 432 to move closer to the bending support frame 3, thereby increasing the gap between the two corresponding retractable support plates 43. In this way, the regulation of the gap between the two corresponding cooling sleeves 46 is realized, which can effectively meet the cooling and shaping requirements of different billets.

[0031] The molten metal enters the die orifice 11 through the crystallizer body 1, and then flows to the lower side of the die orifice 11 after being preliminarily shaped by the crystallizer body 1 and the die orifice 11. Through the cooperation of the cooling sleeves 46 and the guide rollers 5 at two corresponding positions, the cooling and shaping effect on the billet is realized. And under the continuous conveying drive of the cooling sleeve 46, the billet is continuously cooled and shaped until it is completed and then conveyed to the next process. When the billet passes between the cooling sleeves 46 at two corresponding positions, while the billet is being cooled and conveyed by the cooling sleeve 46, due to the elastic effect of the cooling sleeve 46, a certain extrusion effect will be exerted on the elastic induction plate 62 located inside the cooling sleeve 46. The trigger block 63 in the elastic induction plate 62 is extruded to generate a contact trigger signal and transmit data to the cooling and shaping feedback module. The cooling and shaping feedback module transmits the trigger signal to the data analysis and processing module. The data analysis and processing module determines that the cooling and shaping effect of the billet at this time is effective and maintains the gap between the two corresponding positions. When the trigger block 63 in the elastic induction plate 62 is not extruded by the billet or the extrusion is uneven, the cooling and shaping feedback module does not receive the trigger signal of the trigger block 63 or the trigger block 63 is in an untriggered state, and this data is transmitted to the data analysis and processing module. The data analysis and processing module judges according to the received shaping feedback data that the shaping pressure of the cooling sleeve 46 acting on the billet at this time is small, that is, the gap between the cooling sleeves 46 at the two corresponding positions is large. When the gap is large, the billet cannot be effectively cooled and shaped, and the surface contact between the billet and the cooling sleeve 46 is incomplete, thereby reducing the cooling uniformity of the billet and resulting in a decline in the quality of the billet. Therefore, the data analysis and processing module adjusts the cooling contact control module according to the received data, so that the control hydraulic mechanism inputs hydraulic oil into the hydraulic telescopic sleeve 433 through the hydraulic branch pipe 434, causing the hydraulic telescopic sleeve 433 to move away from the bending support frame 3, reducing the gap between the cooling sleeves 46 at the two corresponding positions, ensuring the effectiveness of the contact surface with the billet, promoting the effectiveness of the cooling temperature transfer, ensuring the effectiveness of the cooling sleeve 46 in cooling and shaping the billet, and ensuring the quality of the billet. And after the gap between the cooling sleeves 46 at the two corresponding positions is reduced, the billet exerts an extrusion effect on the cooling sleeve 46, which in turn acts on the elastic induction plate 62, causing the trigger block 63 in the elastic induction plate 62 to be fully triggered. The cooling and shaping feedback module receives this data and then transmits it to the data analysis and processing module. The data analysis and processing module can judge the effectiveness of the action on the cooling contact control module according to the data transmitted by the cooling and shaping feedback module, and then maintain or continue to adjust the control command of the cooling contact control module according to the judgment of the effectiveness to ensure the effectiveness of the billet.

[0032] After the data analysis and processing module issues contact regulation to the cooling contact regulation module to regulate the gap between the cooling sleeves 46 at two corresponding positions, when the data analysis and processing module determines through the data transmitted by the cooling and shaping feedback module that the extrusion pressure exerted by the cooling sleeve 46 on the billet still has not reached the full trigger of the trigger block 63, while the data analysis and processing module continues to act on the cooling contact regulation module for regulation, it also issues a drive regulation instruction to the drive auxiliary regulation module to reduce the rotation speed of the conveying motor mechanism 42, thereby reducing the conveying speed of the billet, ensuring the formation of the billet thickness and the effectiveness of billet cooling. Through the dual regulation of the cooling gap and the conveying speed, the quality of the billet is ensured, the scrap rate is reduced, and the quality stability during continuous casting is ensured, promoting the economic benefits of continuous casting; Moreover, after the data analysis and processing module regulates the drive auxiliary regulation module, the rotation speed collector in the guide roller 5 can transmit the rotation data of the front and rear guide rollers 5 to the crystal conveying data acquisition module, enabling the data analysis and processing module to verify the effectiveness of the execution of the regulation instruction of the drive auxiliary regulation module based on the data transmitted by the crystal conveying data acquisition module, thereby realizing the verification of the effectiveness of the drive auxiliary regulation module and the conveying motor mechanism 42, and further avoiding the situation where the data analysis and processing module cannot detect in time when an abnormality occurs, resulting in continuous quality abnormalities of the billet.

[0033] The data analysis and processing module can independently regulate the gap between the cooling sleeves 46 at two corresponding positions at different positions. On the one hand, it can effectively achieve the adaptive regulation of the billet cooling and shaping effect, ensure the effective contact between the billet and the cooling sleeve 46, promote the cooling effect and uniformity of the billet, and ensure the billet quality. On the other hand, it can also judge the hydraulic regulation data that the hydraulic telescopic sleeves 433 can receive distributed in sequence according to the conveying direction of the billet, enabling the data analysis and processing module to conduct data verification and regulation on the overall billet cooling and shaping process, ensure the cooling and shaping quality of the billet, and can also promote the self-adaptive modification of the subsequent billet cooling and shaping parameters in a timely manner through the regulation of the cooling contact regulation module at the abnormal budding stage to ensure the effectiveness and functionality during the continuous cooling process of the billet, thereby reducing the scrap rate of the billet.

[0034] During the continuous operation of the crystallizer body 1, the data analysis and processing module transmits the cooling and shaping data and the status of the ingot during the operation of the crystallizer body 1 to the continuous casting control platform through the cooling and crystallization data display module, and when the cooling and shaping feedback module transmits the situation that the trigger block 63 is not triggered or triggered incompletely, the abnormal alarm data is transmitted to the continuous casting control platform through the abnormal alarm module, and the alarm set on the continuous casting crystallization controller is controlled to start, so that the technicians can observe the abnormal data and obtain the abnormal position. When the subsequent data analysis and processing module causes the abnormality to recover through the action of the cooling contact control module, the alarm is lifted. When the subsequent data analysis and processing module causes the abnormality to persist through the action of the cooling contact control module, the technicians will check the abnormality in time and take effective emergency measures to avoid economic losses caused by continuous operation.

[0035] Second implementation method: Figure 1 - Figure 10 The continuous casting crystallizer adaptive control system is shown, and the input end of the cooling and shaping feedback module is also connected to the top trigger acquisition module and the bottom trigger acquisition module. The input end of the top trigger acquisition module is connected to the trigger block 63 signal on the side close to the die opening 11, and the input end of the bottom trigger acquisition module is connected to the trigger block 63 signal on the side far away from the die opening 11. The setting of the top trigger acquisition module and the bottom trigger acquisition module can assist the cooling and shaping feedback module to effectively judge the trigger state of each trigger block 63 in the elastic sensing plate 62, and then effectively obtain the actual cooling state of the billet, and can make applicable adjustments in time and effectively when there is a trigger anomaly, so as to ensure the quality of the billet, effectively improve the accuracy of data transmission of the cooling and shaping feedback module, improve the accuracy of obtaining the cooling abnormal state, as well as the timeliness and effectiveness of the regulation, reduce the calculation burden and difficulty of the data analysis and processing module, thereby improving the response timeliness of the self-adaptive regulation of the crystallizer body 1, effectively reduce the scrap rate and production cost, and promote the economic benefits of continuous casting.

[0036] Figure 7 - Figure 9 It is shown that a plurality of elastic sleeves 64 are fixedly connected between the inner wall of the elastic sensing cavity close to the bending support frame 3 and the inner wall of the elastic sensing cavity away from the bending support frame 3, and the elastic sleeves 64 are sleeved on the outer sides of the corresponding trigger blocks 63. The setting of the elastic sleeves 64 can effectively promote the elastic effectiveness of the elastic sensing plate 62, the triggering accuracy of the trigger block 63, and the effectiveness of subsequent data feedback.

[0037] Figure 1 - Figure 10When the local trigger data of the trigger block 63 is received by the cooling and shaping feedback module, when the trigger block 63 near the die orifice 11 generates a trigger, it will transmit the signal of the top trigger to the top trigger acquisition module. When the trigger block 63 far from the die orifice 11 generates a trigger, it will transmit the signal of the bottom trigger to the bottom trigger acquisition module. The cooling and shaping feedback module judges the triggering situation of the trigger block 63 in the elastic induction plate 62 at this time by receiving the data of the bottom trigger acquisition module and the top trigger acquisition module, and transmits it to the data analysis and processing module. The data analysis and processing module can effectively judge the shape data of the billet and generate appropriate regulation instructions according to the shape of the billet; When receiving the signal that the trigger block 63 in the elastic induction plate 62 is triggered at the top and not triggered at the bottom, the data analysis and processing module judges that the billet is in a top accumulation state at this time. The conveying speed of the billet cannot effectively meet the flowing speed of the molten metal in the mold body 1, and the gap between the two corresponding cooling sleeves 46 is small. Furthermore, the data analysis and processing module regulates the drive auxiliary regulation module, making it increase the rotation speed of the conveying motor mechanism 42 to promote the movement of the billet, avoid the accumulation of molten metal, and cause problems with poor cooling quality of the billet. And it also controls the hydraulic mechanism through the cooling contact regulation module, outputs the hydraulic oil in the hydraulic telescopic sleeve 433, so that the hydraulic telescopic sleeve 433 drives the moving plate 432 to move closer to the bending support frame 3 under the action of its own elastic force, increasing the gap between the two corresponding cooling sleeves 46, and avoiding excessive extrusion of the cooling sleeve 46 on the billet, resulting in problems such as poor billet movement and subsequent decline in billet quality. The data analysis and processing module can realize the adaptive regulation of the abnormal cooling germination of the billet through the coordinated control of the drive auxiliary regulation module and the cooling contact regulation module; When receiving a signal that the trigger block 63 in the elastic induction plate 62 is not triggered at the top but triggered at the bottom, the data analysis and processing module determines that the billet is in a state of bottom accumulation at this time. The conveying speed of the billet cannot effectively meet the flow rate of the molten metal in the mold body 1, and the gap between two corresponding cooling sleeves 46 is relatively large. Furthermore, the data analysis and processing module exerts a regulatory effect on the drive auxiliary control module to increase the rotation speed of the conveying motor mechanism 42, promote the movement of the billet, avoid the accumulation of molten metal, and prevent problems such as poor cooling quality of the billet. Additionally, the cooling contact control module controls the hydraulic mechanism to input hydraulic oil into the hydraulic telescopic sleeve 433. Under the action of the hydraulic oil, the hydraulic telescopic sleeve 433 continues to undergo elongation deformation, driving the moving plate 432 to move away from the bending support frame 3, reducing the gap between two corresponding cooling sleeves 46, ensuring the contact area of the cooling sleeves 46 acting on the billet, ensuring the effectiveness of the cooling and shaping of the billet, and ensuring the quality of the billet. The data analysis and processing module can achieve the adaptive regulation effect on the budding of abnormal billet cooling through the coordinated control of the drive auxiliary control module and the cooling contact control module; When receiving signals that both the top and bottom of the trigger block 63 in the elastic induction plate 62 are triggered, and the cooling and shaping feedback module has not yet obtained the full-trigger data of the trigger block 63 in the elastic induction plate 62, or when receiving signals that neither the top nor the bottom of the trigger block 63 in the elastic induction plate 62 is triggered, and the cooling feedback module obtains data indicating that there is partial triggering of the trigger block 63 in the elastic induction plate 62, the data analysis and processing module determines that the billet is in an uneven state at this time, and the elastic effect of the cooling sleeve 46 is damaged, unable to effectively extrude the billet, thus causing uneven cooling and shaping of the billet. The data analysis and processing module transmits abnormal regulation data to the abnormal warning module, causing the abnormal warning module to transmit an abnormal signal of the cooling sleeve 46 to the continuous casting control platform and activate the alarm to issue an alarm reminder, enabling technicians to promptly obtain abnormal data and timely control the continuous casting process, and subsequently replace the damaged cooling sleeve 46 to ensure the quality of subsequent continuous casting.

Within the scope of knowledge possessed by those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of the present invention.
