Description

TECHNICAL FIELD

[0001] The present application relates to the slab continuous casting process automation technology, more particularly, to a kind of automatic sealing method of slab continuous casting machine crystallizer. BACKGROUND

[0002] At present, the sealing process operation of the crystallizer of slab continuous casting machine at home and abroad is still the traditional manual operation mode, which includes the following basic operations: preparation: dummy head preparation, crystallizer inspection, dummy bar insertion; sealing operation: dummy head position and angle adjustment, gap filling between crystallizer and dummy head, protective material placement, cooling material placement, iron scrap addition, etc. Although various sealing process methods have been developed due to the improvement of the dummy head and some specific conditions on site, such as the improvement of the crystallizer sealing method and the corresponding improvement of the process after the partial improvement of the dummy head to realize automatic dummy removal; to solve the continuous casting start-up leakage, the sealing preform is improved based on the original sealing scheme, and the sealing method of other casting machines at home and abroad is also used for reference, and the application of spring ring and other cooling materials is increased; the crystallizer sealing assembly is developed to simplify the sealing operation, etc. However, the crystallizer sealing operation still has the following characteristics:

[0003] (1) Two people are needed to perform the sealing operation at the same time, the process labor intensity is high, and the standardization requirement is high;

[0004] (2) Fiber materials are used to fill the gap between the crystallizer copper plate and the dummy head during sealing;

[0005] (3) The size adjustment of the dummy head and the insertion centering operation of the dummy bar require excessive manual participation and confirmation.

[0006] These three characteristics make the crystallizer sealing operation a difficult point in the current continuous casting automation operation process. Therefore, through technical means, the operation simplification and automation of the entire process of the crystallizer sealing of slab continuous casting are the goals that every continuous casting person always pursues, which are to reduce the labor intensity of on-site operators, eliminate the safety hazards of crystallizer sealing operation on personnel in complex environment, match the personnel allocation problem after the continuous advancement of continuous casting automation process, and eliminate the adverse effects of non-standard manual operation in traditional sealing method on subsequent production and quality control.

[0007] The existing crystallizer preparation and related sealing operation process:

[0008] The continuous casting crystallizer start-up preparation belongs to the work before continuous casting, and at present, manual operation is basically adopted at home and abroad, which is a labor-intensive operation, and the basic process is as follows:

[0009] 1) Dummy head size adjustment: according to the process standard of subsequent pouring, the size of the dummy head is adjusted (adjusting block) or replaced (the adjustment of the dummy head under the same thickness specification is mainly to ensure the matching of the dovetail groove width and the pouring width).

[0010] 2) Mold cleaning, inspection and confirmation: after the final pouring of a CAST, the copper plate of the mold must be cleaned (surface and corner gap), the copper plate surface condition (including gap size) is inspected, the nozzle is inspected (mainly including the water spraying condition of the front three zone secondary cooling water); the width and taper of the mold are adjusted and measured; the corner sealing glue is protected, the mold surface is oiled (lubricant, part of the caster is first opened to the maximum width of the mold, and then the width taper of the mold is adjusted after the dummy bar is inserted); the mold copper plate protection plate is placed.

[0011] 3) Dummy bar insertion: the dummy bar trolley is driven to the side of the mold, and then the core is adjusted, centered and confirmed, and then the dummy bar is inserted into the mold in the insertion mode. Before the insertion hook of the dummy bar conveying chain is unhooked, the related driving rollers are stopped, and the driving rollers are started to complete the unhooking of the dummy bar after the clamping effect is confirmed by the driving rollers. During the whole process of conveying the dummy bar, due to the gap between the dummy bar links and the position deviation of the conveying chain, in order to prevent the interference between the dummy head and the short side copper plate or the left and right position deviation of the dummy head in the mold, manual dynamic adjustment is required to correct the deviation, so that the dummy bar is in the middle position when it enters the mold, and a certain gap is left around. Then the driving rollers are started manually (automatically) to continue feeding the dummy bar into the mold. When the dummy head is completely inserted into the mold, the dummy bar trolley can be withdrawn to the winch standby position. The dummy bar continues to be fed down, and stops when the upper edge of the dummy head reaches the specified height (this height is fixed, and a custom scale is generally used for measurement. If it is less than or exceeds the specified height, a small amount of adjustment can be made through the pinch roller). After the dummy bar is inserted in place, the associated driving rollers can be locked, the mold vibration position can be kept unchanged, and the height of the dummy head can be kept unchanged by selecting the retention mode.

[0012] 4) Mold sealing operation: after the dummy bar is inserted in place, two people in each flow 2 perform sealing operation, and the basic steps are to first align the dummy head, place the pre-prepared fiber sealing strip into the mold gap and tamp it in turn, place the protective material, place the cooling material, and add iron filings.

[0013] Based on the above, there are several problems in the whole mold sealing process:

[0014] 1) The whole process from the preparation of the dummy head to the completion of the mold sealing is a hard work, and during the sealing process, the operation personnel cannot wear a safety helmet, which poses a certain risk to the operation safety;

[0015] 2) Dummy bar insertion, mold sealing and other operations are a more stringent specification work, in which the dummy bar size does not match, the dummy bar skew is not confirmed easily leading to the damage of the short side copper plate of the mold and the width adjusting cylinder; poor mold sealing easily leads to the accidents of opening pouring leakage, failure of stripping, and separation of the dummy head and the head of the cast slab in the caster;

[0016] 3) The materials for sealing include sealing strips and iron nail scraps, which are partially detached during the opening pouring process, causing pollution to the inside of the caster, in which most of the detached iron nail scraps are washed away by the secondary cooling water, but a part of them will cause pollution to the nozzle, and the detached sealing strips will stay in the roller gap for a long time, affecting the secondary cooling effect of the nozzle. SUMMARY

[0055] In order to better understand the above technical solutions of the present application, the technical solutions of the present application are further explained below in combination with the drawings and examples.

[0056] The present application provides an automatic sealing method for a slab continuous casting machine crystallizer, comprising:

[0057] 1. The dummy bar head is set as an adjustable structure;

[0058] 2. The crystallizer preparation and confirmation work is adjusted as an automatic operation;

[0059] 3. The insertion work of the dummy bar rod is adjusted as an automatic operation;

[0060] 4. The dummy bar head is automatically sealed by using a sealing prefabricated part.

[0061] In the above first aspect, the dummy bar head is divided into two parts, including a movable structure 100 located in the upper half and a fixed structure 200 located in the lower half.

[0062] The movable structure 100 and the fixed structure 200 are connected through a clamping groove and a clamping buckle, and are further fixed through a mortise and tenon structure.

[0063] In combination with Figure 1 (a) shown, the movable structure 100 includes a left half of the steel-facing surface 101, a right half of the steel-facing surface 102, and a plurality of segmented blocks 103 arranged between the left half of the steel-facing surface 101 and the right half of the steel-facing surface 102.

[0064] By arranging different numbers of segmented blocks 103 between the left half of the steel-facing surface 101 and the right half of the steel-facing surface 102, the size of the dummy bar head can be adjusted.

[0065] In combination with Figure 1 (b) shown, the movable structure 100 includes a left half of the steel-facing surface 101, a right half of the steel-facing surface 102, and a telescopic mechanism 103 arranged between the left half of the steel-facing surface 101, the right half of the steel-facing surface 102, and the fixed structure.

[0066] In combination with Figure 1 (c) shown, the telescopic mechanism 103 includes an upper guide rail arranged on the left half of the steel-facing surface 101 and the right half of the steel-facing surface 102, an upper rack 104 arranged on the upper guide rail, a lower guide rail arranged on the fixed structure, a lower rack 105 arranged on the lower guide rail, and a gear 106 engaged with the upper rack 104 and the lower rack 105.

[0067] Gear 106 is driven by motor, rotating to drive the upper rack 104, lower rack 105 movement, so that the movable structure 100 conveniently to both sides of the telescopic, while the mobile after the middle part of the vacancy is filled by a special filler block (with both sides of the movable part has similar mortise and tenon structure positioning) and other related mechanical equipment, so that the dummy head from the mechanical structure to do telescopic adjustment function, thus eliminating the operation of changing the dummy head, quickly realize the size of the dummy head adjustment.

[0068] In the above-mentioned second aspect, the integrated cleaning tool and the integrated oiling tool are used for the cleaning of the crystallizer copper plate, the clearance between the corners, the inspection of the copper plate surface, the inspection of the two cooling water of the 0# section, the adjustment of the width taper of the crystallizer, the use of sealing glue, the lubricant coating on the copper plate surface, and the placement of the crystallizer protection plate.

[0069] In the above-mentioned third aspect, a guide device is arranged between the dummy head 1 and the dummy bar trolley 2.

[0070] In combination with Figure 2 As shown in (a), the guide device comprises guide rollers 3 arranged on both sides of the dummy head 1 and a correction plate arranged at the entrance of the crystallizer; each of the two guide rollers 3 comprises a guide roller body and a central shaft arranged in the guide roller body; the lower ends of the two central shafts are connected by an extension tooth.

[0071] The dummy head 1 needs to be adjusted in position before entering the crystallizer. At present, after the dummy head 1 enters the crystallizer, it must be manually adjusted by a pry bar to the left and right position, and the gap between the two sides is basically uniform (when the dummy bar is inserted into the crystallizer, there is often a slight deviation to the left and right, which is ultimately caused by the relationship between the side guide and the position of the conveying chain during the recovery process of the dummy bar, resulting in that the insertion hook is not in the center position of the dummy bar or the deviation of the width of the two sides when the crystallizer is prepared) In this case, the adjustment only plays a role in maintaining the seal, and too small a gap on one side can easily cause the dummy head to squeeze the crystallizer and the foot roller when passing through the lower opening and the side foot roller of the crystallizer after the pouring, resulting in taper alarm and other phenomena (to achieve better results, the dummy head is finally adjusted by a pry bar while being lowered into the crystallizer, otherwise there will be some risks, but this dynamic adjustment work poses certain safety problems for humans).

[0072] In combination with Figure 2 As shown in (b), the guide device comprises a guide frame 3 arranged outside the dummy bar trolley 2, a guide corner 4 arranged on the guide frame 3, and a guide groove 5 arranged on the dummy head 1 and matched with the guide corner 4.

[0073] The guide groove 5 behind the dummy head 1 and the guide frame 3 of the front drum of the dummy bar trolley 2 are mainly used for guiding the offset position of the dummy head 1 in the left and right directions before entering the crystallizer, and the movable guide of the front baffle of the dummy bar trolley 2 is mainly used for correcting the front and rear offset of the dummy head 1.

[0074] Based on the ingot head 1 each time in the entry of the mold always need to ensure the central position, therefore through the guide device can in the ingot rod conveying process to the ingot head 1 for the offset amount self-adjusting, using the ingot rod trolley 2 end installation chamfer, front baffle installation movable guide wheel, and the ingot head 1 sets up the adjusting groove, and the guide frame 3 and so on multiple ways to the offset amount of ingot head is corrected. Ensure the accuracy of the ingot head entering position.

[0075] The guide frame 3 will be placed above the mold, the ingot head 1 can be more accurate position in the transition to the mold, and ensure that after entering the mold can always keep in the middle position, play the role of guide and gradually correct the ingot head position, the guide frame 3 can be removed after the ingot completely enters the mold.

[0076] After the ingot completely enters the mold, it is necessary to pry the ingot head 1 with a pry bar on the outer arc side of the copper plate of the mold, and to push the ingot head 1 to the inner arc direction to eliminate the verticality defects of the ingot head caused by the gap of the anti-falling device (to prevent the ingot head from being straightened after starting due to the effect of the blank force, which leads to sealing failure and stress concentration at the corner, which is one of the important reasons for causing casting leakage); the improvement of this operation will be an important measure to avoid casting leakage, which is inspired from long-term operation.

[0077] The front baffle of the ingot rod trolley 2 is changed into a movable elastic baffle, but when the ingot head 1 passes through this position (the ingot head is thick), it is automatically swung to the inner arc side direction under the action of the baffle elastic force, realizing the automatic adjustment of the attitude of the ingot head 1.

[0078] In the preparation of the mold, the cleaning work of the residual protective slag of the mold cover plate is carried out by the dust collector (to prevent dust from being blown by water and air and to prevent the nozzle from being contaminated after entering the casting machine).

[0079] Combined Figure 4 As shown in the above-mentioned fourth aspect, the sealing preform includes a corner sealing piece 10, an outer piece 11 and a dovetail groove sealing piece 12, which are all made of tinplate material and have a protective function for the surface of the ingot head 1. The sealing preform can be customized or pressed on site (the corresponding mold equipment must be provided). At the same time, the sealing preform should consider the corner wrapping effect (i.e. the sealing preform is divided into several parts, one piece for each of the two short sides, one or two pieces for the inner arc, one piece for the outer arc dovetail groove corner, and one piece for the middle). The thickness of the sealing preform is more than 1 mm, the depth of the gap between the ingot head and the copper plate is kept at 10-15 cm, the part above the upper part of the ingot head is more than 30 cm, and it is ensured to be close to the copper plate. The width of the folded and placed part on the side of the ingot head should be different according to different positions (the dovetail groove part is relatively special).

[0080] The corner seal 10 is arranged at the corner position of the outer side of the dummy head; the outer part 11 is arranged at the length direction position of the outer side of the dummy head; and the dovetail groove seal 12 is arranged at the width direction position of the outer side of the dummy head.

[0081] After the insertion of the sealing preform, iron filings with a thickness of 1-2 cm are spread at the folding position (corner) of the sealing preform (the iron filings are used to prevent the direct impact of the open pouring molten steel on the preform into the copper plate of the crystallizer and the dummy head, causing abnormal open pouring resistance.

[0082] Finally, the integrated tensioning rib and cooling block are placed above the dovetail groove.

[0083] The working principle of the present application is as follows:

[0084] The automatic sealing solution aims to integrate all manual sealing steps and is designed by using automatic control and online monitoring methods, and combined with manual intervention measures to develop a new type of full-automatic crystallizer automatic sealing device. This device can realize the functions of replacing manual sealing and online monitoring and confirming the integrity of the sealing. The mechanism can be unaffected by the factors of design and process requirements of the caster, and can realize automatic sealing of the caster without personnel operation, automatic and high-precision full crystallizer open pouring sealing operation, to solve the influence of the result error caused by the operation of human factors, reduce the labor intensity of the site operation, improve the automation degree and reliability of the continuous casting machine and other problems.

[0085] In view of the limitations of the existing crystallizer sealing tool and the high intensity of manual operation, the fullness and convenience of the crystallizer sealing cannot be met, therefore, the present application provides an automatic sealing method for a slab continuous casting machine crystallizer. The automatic sealing method of the present application can be unaffected by the factors of design and process requirements of the caster, based on the imitation of manual operation steps, forms an independent and branched combined device, and considering the convenience of receiving operation, without affecting the requirements of the device itself, the corresponding improvement scheme is used.

[0086] The automatic sealing method of the present application fully integrates automatic control operation into the multifunctional manipulator to replace the manual sealing operation, and combines the simulation system control and online monitoring technology to achieve the completeness of the crystallizer sealing.

[0087] The multifunctional manipulator to replace the manual sealing realizes the following functions:

[0088] Mode 1 (cleaning): the inner surface of the crystallizer 15 is cleaned, the motor 16 drives the rolling shaft 17 (wrapped with cleaning cotton) to automatically clean, the inner end of the shaft is provided with a dust suction device 18, and the cleaned sundries are sucked into a dust storage bag, as shown in Figure 5 .

[0089] Mode 2 (oiling): after mode 1, start the oil pump 19 to deliver lubricating oil to the oil nozzle 21 through the oil delivery pipe 20, and the oil nozzle 21 sprays lubricating oil in the crystallizer, as shown in Figure 6 . .

[0090] Mode 3 (entry height of dummy bar): insert the embedded integrated monitoring eye module and turn it on, measure the height between the dummy bar head 23 and the entrance of the crystallizer 24 by using the laser range finder 22, feed the measurement data to the display panel, remotely and automatically control the speed of the crystallizer, and accurately adjust the height of the dummy bar head (according to the data parameters of different continuous casting machines, the height parameter can be freely adjusted), as shown in Figure 7 . .

[0091] Mode 4 (adjusting the position of the dummy bar head): automatically insert the mechanical pry bar 25 to the center position outside the dummy bar head 23, and correct and adjust the dummy bar head 23 (the direction is from the outer arc to the inner arc), and automatically recover the mechanical pry bar 25 after the end, as shown in Figure 8 . .

[0092] Mode 5 (slab sealing): after the adjustment of the dummy bar is completed, enter the sealing stage, according to the measured three-dimensional data of the crystallizer, automatically place the tinplate prefabricated part, and use the lifting hand to place the tinplate prefabricated part around the dummy bar head, and fill the gap between the dummy bar head and the crystallizer. .

[0093] Mode 6 (mechanical expansion and cutting): first, after the position sensor confirms and feeds back the position in the crystallizer, the spring pressure rod 26 expands, pushes against the copper plate around the crystallizer, and presses down until the crystallizer and the dummy bar head are completely filled around, and the spring pressure rod 26 is recovered, as shown in Figure 9 . .

[0094] Second, use the embedded integrated monitoring eye module for secondary imaging to detect the sealing state of the crystallizer. .

[0095] As shown in Figure 10 , the embedded integrated monitoring eye module includes a light source emitter 27 (including a laser range finder), a signal receiving panel 28, and a metal contact point 29. .

[0096] Mode 7 (laying of nail scrap): automatically and uniformly spread the nail scrap on the surface of the dummy bar head, and automatically turn off after one cycle, the thickness of the corner laying is 15-30 mm, and the thickness of the plane laying is 5-10 mm, as shown in Figure 11 . .

[0097] Mode 8 (laying of reinforcing ribs according to position): according to the position of the dummy bar head, automatically lower the reinforcing ribs, and recover the lowering hook. .

[0098] Mobile design concept: .

[0099] This stage is the solution of the automatic sealing technology of continuous casting crystallizer, wherein two movable schemes can be implemented:

[0100] The dummy bar is used to supply power and the multifunctional manipulator is designed on the head of the dummy bar.

[0101] A separate movable trolley is designed to perform subsequent automatic sealing operation after the dummy bar is removed.

[0102] The two schemes have different advantages and disadvantages. The multifunctional manipulator integrated with the dummy bar can improve the utilization of space and can be externally connected to the dummy bar to supply power as a drive. The independent movable trolley is driven by a portable lithium battery without power supply. The scheme can be combined with the integrated facilities to have greater expandability.

[0103] Crystallizer sealing state imaging technology:

[0104] The online visual monitoring device is used to remotely confirm the sealing state. The current imaging technology has reached this standard level.

[0105] Based on the application of the imaging technology, a crystallizer sealing monitoring system is developed to automatically identify the collected sealing state data and automatically warn and adjust when an abnormality occurs.

[0106] The application of the multifunctional manipulator will be initially set and adjusted in the development software according to different parameter conditions of the crystallizer, so that the automatic sealing is more suitable for different continuous casting crystallizers.

[0107] In the present invention, the collection of real imaging data will use remote data transmission technology to realize the real-time observation of the state of the automatic sealing of the crystallizer in the field and the central control linkage, and can timely control the operation in the form of manual intervention to make up for the emergency measures of the automatic sealing control after an abnormality occurs.

[0108] In the second design scheme, the movable independent trolley is humanized to consider convenience and expandability, and will be combined with the functional base area linkage technology and integrated with the embedded monitoring technology. In the same scene, multiple continuous casting machines can use the same movable trolley to complete the sealing work.

[0109] This scheme will be a breakthrough in the automatic sealing technology of continuous casting crystallizer, which will greatly avoid the disadvantages of manual sealing operation, greatly reduce the labor intensity of sealing operation, improve the convenience, reliability and accuracy of the sealing of the continuous casting crystallizer, and is specially designed to improve the detection accuracy of the sealing operation of the crystallizer.

[0110] The present application firstly re-modifies the crystallizer sealing piece in the industry, and evolves as the main process of the sealing scheme, the theoretical basis is mature, and the on-site experiment effect is effectively verified. And expand to the whole crystallizer sealing operation with automation, device, humanization change, the system scheme intervenes many improvement and improvement measures, integrates many advanced methods in the industry including automatic detection, automatic adjustment, automatic operation, real-time monitoring, accident warning, etc. The sealing operation of similar occasions of continuous casting machine has high application value. It can be popularized and used in domestic large steel enterprises, and has very broad application prospect.

[0111] The present application is used for realizing the automatic sealing process control and operation of the slab continuous casting crystallizer in the unmanned and few people state, reduces the labor operation intensity under the current intelligent promotion and complex operation environment, and avoids the adverse effects of the instability of the labor operation of this link on the casting subsequent production accident wages and the control of the slab quality.

[0112] Those skilled in the art in the technical field should recognize that the above embodiments are only used to illustrate the present application, and are not used as the limitation of the present application, as long as the changes and modifications of the above described embodiments are within the spirit and principle of the present application.
