Description

Technical Field

[0001] The present application relates to the technical field of continuous casting equipment, and in particular to a copper slab continuous casting crystallizer device. Background Art

[0002] Copper alloys are widely used in industrial production due to their good mechanical properties. Continuous casting equipment is usually used to produce copper slabs. The crystallizer is one of the core components of the continuous casting equipment. It is mainly used to cool and crystallize the molten metal raw materials during the continuous casting process to solidify them into metal billets with a certain shape and strength.

[0003] An existing crystallizer usually has a graphite mold inside, and cooling plates made of a material with good thermal conductivity are arranged on both sides of the graphite mold. A cooling cavity is arranged outside the cooling plate. The cooling plate is cooled by injecting circulating cooling water into the cooling cavity, and then the cooling plate exchanges heat with the metal raw material entering the crystallizer through the graphite mold, thereby cooling the metal raw material.

[0004] In the process of cooling and crystallizing the molten copper alloy material into a copper slab by the above-mentioned crystallizer, since the cooling water easily forms convection between the water inlet pipe and the water outlet pipe, the cooling water cannot flow evenly to all parts of the cooling chamber, so that the cooling plate cannot be evenly cooled, which easily leads to a decrease in the cooling efficiency of the copper alloy material, and ultimately leads to a slow crystallization speed of the copper alloy material, thereby reducing the production efficiency of the copper slab. Summary of the invention

[0005] In order to improve the cooling efficiency of copper alloy materials, the present application provides a copper slab continuous casting crystallizer device.

[0006] The present application provides a copper slab continuous casting crystallizer device, which adopts the following technical solution: A copper slab continuous casting crystallizer device comprises a box body, a graphite mold, a cooling plate and a cooling assembly; the graphite mold is arranged inside the box body, and both the graphite mold and the box body are provided with forming grooves, and the graphite mold and the forming grooves on the box body are connected; two cooling plates are provided, and the cooling plates are fixedly arranged in the box body and respectively located on both sides of the graphite mold; a cooling cavity is formed between the cooling plate and the box body; a cooling assembly is provided on the box body, and the cooling assembly is used to inject circulating cooling water into the cooling cavity; a guide plate is fixedly provided on the cooling plate, and a plurality of guide plates are provided, and the guide plates are located in the cooling cavity, and the guide plates are used to guide the cooling water in the cooling cavity so that the cooling water flows in an S shape through various parts of the cooling cavity.

[0007] By adopting the above technical scheme, when the continuous casting production of copper slabs is carried out, the molten copper alloy melt flowing out of the continuous casting machine enters the forming tank, and the cooling assembly is used to inject circulating cooling water into the cooling wall. The cooling water contacts the cooling plate to cool the cooling plate, and then the cooling plate exchanges heat with the copper alloy melt through the graphite mold, so that the copper alloy melt is cooled and crystallized, and is shaped in the forming tank, and finally passes through the forming tank to form a copper slab. A guide plate is set in the cooling cavity to guide the cooling water in the cooling cavity, so that the cooling water flows along the S shape through various parts of the cooling cavity and fully contacts various parts of the cooling plate, so that the cooling plate can be evenly cooled, thereby improving the cooling efficiency of the copper alloy material.

[0008] , The cooling panel is connected with the cooling panel by the spring, and the cooling panel has two limit switches, which are respectively connected to the cooling panel and the cooling panel at two ends. The cooling panel has two limit switches, which are connected to the cooling panel at two ends. The cooling panel has two limit switches, which are respectively connected to the cooling panel and the cooling panel at two ends.

[0009] By adopting the above technical solution, after the continuous casting production continues for a certain period of time, scale is easily generated at the position where the surface of the cooling plate contacts the cooling water, and the scale will reduce the cooling efficiency of the cooling water on the cooling plate. At this time, the operator shuts down the continuous casting machine, and uses the driving component to drive the scraper and the slide plate to slide. When the scraper slides, it scrapes the surface of the cooling plate to make the scale attached to the surface of the cooling plate fall off, and then uses the driving component to drive the scraper to slide and reset, and the continuous casting production can continue. Using the scraping component, the operator can regularly scrape the scale on the cooling plate to prevent the attached scale from affecting the cooling efficiency of the cooling water on the cooling plate, thereby improving the cooling efficiency of the copper alloy material.

[0010] Optionally, two mounting grooves are provided on the side panel, the mounting grooves correspond to the cooling chamber one by one, and the mounting grooves are communicated with the cooling chamber; the driving components are provided in two groups and are respectively located on both sides of the scraper, and the driving components include a lead screw, a slider and a motor; the lead screw is rotatably provided in the mounting groove; the slider is slidably provided in the mounting groove and is threadedly connected to the lead screw, and the slider is fixedly connected to one end of the scraper; the motor is provided on the box, and the motor is used to drive the lead screw to rotate.

[0011] By adopting the above technical solution, when scraping the scale on the cooling plate, the motor is used to drive the lead screw to rotate, thereby driving the slider and the scraper to slide relative to each other.

[0012] Optionally, the two sides of the baffle are detachably connected to the two side panels respectively; a fixing component is provided on the box body, and the fixing component is used to fix the baffle and the side panels.

[0013] By adopting the above technical solution, when the graphite mold is worn or copper slabs of different sizes need to be produced, the operator can use the fixing assembly to cancel the fixing of the baffle and the side plate, and then remove the baffle from the side plate, and then take out the graphite mold for replacement. After the replacement is completed, the baffle and the side plate are fixed by the fixing assembly, and the continuous casting production of the copper slab can be continued. The detachable baffle and the fixing assembly are used to enable the operator to replace the graphite mold simply and efficiently, which is not only convenient for the production of copper slabs of different sizes, but also convenient for the maintenance of the graphite mold.

[0014] Optionally, the fixing assembly includes a dovetail bar and a fixing pin; dovetail grooves are provided on both sides of the baffle; two dovetail bars are provided, the dovetail bars correspond one-to-one to the side panels, the dovetail bars are slidably arranged in the dovetail grooves, and are fixedly connected to the side panels; limiting grooves are provided at both ends of the baffle, the limiting grooves are located at both ends of the dovetail groove in the length direction; two fixing pins are provided, and correspond one-to-one to the slide plates, the fixing pins are slidably arranged in the limiting grooves, and are fixedly connected to the slide plates.

[0015] By adopting the above technical solution, the baffle is limited by the dovetail bar and the dovetail groove, so that the baffle can only slide relative to the side plate, and then the two ends of the sliding direction of the baffle are limited by the fixing pin and the limiting groove, so that the baffle is fixed to the side plate. The fixing pin is fixedly connected to the slide plate. When the baffle needs to be disassembled, the scraper and the slide plate are driven to move away from the baffle by the motor, the lead screw and the slider, so that the fixing pin is away from the limiting groove, and the operator can slide the baffle upward relative to the dovetail bar to disassemble the baffle. When the baffle is fixed to the side plate, the self-locking force of the motor is used to fix the fixing pin in the limiting groove, so as to avoid accidental touch during continuous casting production, which may cause the slide plate to slide, thereby causing the baffle to slide relative to the side plate.

[0016] Optionally, a composite material with high thermal conductivity, good wear resistance and corrosion resistance is provided on the inner side wall of the graphite mold.

[0017] By adopting the above technical solution, a composite material with high thermal conductivity, good wear resistance and corrosion resistance is arranged on the inner wall of the graphite mold, that is, the side wall of the forming groove, which can effectively reduce thermal resistance and improve heat transfer efficiency, while enhancing the wear resistance and corrosion resistance of the graphite mold, thereby reducing the number of replacement times of the graphite mold, reducing the impact on continuous casting production, and improving continuous casting production output.

[0018] Optionally, two groups of cooling components are provided, and correspond one-to-one with the cooling chambers. The cooling components include a water inlet pipe and a water outlet pipe. Both the water inlet pipe and the water outlet pipe are connected to the cooling chamber, and the guide plates are located between the water inlet pipe and the water outlet pipe.

[0019] By adopting the above technical solution, during continuous casting production, the water inlet pipe and the water outlet pipe are both externally connected to a chiller for providing cooling water. The cooling water enters the cooling chamber through the water inlet pipe, and then flows back to the chiller through the water outlet pipe, thereby injecting circulating cooling water into the cooling chamber.

[0020] After the scale is scraped off, the operator can connect an external water source to the water inlet pipe and use the water to discharge the scale in the cooling chamber through the water outlet pipe.

[0021] Optionally, the guide plate is made of the same material as the cooling plate.

[0022] By adopting the above technical solution, the guide plate is also made of a material with good thermal conductivity, which can not only guide the cooling water, but also increase the heat transfer area between the cooling plate and the cooling water, further improving the cooling efficiency of the cooling plate, thereby improving the cooling efficiency of the copper alloy material.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: 1. By setting a guide plate in the cooling chamber, the cooling water in the cooling chamber is guided so that the cooling water flows along an S-shape through the cooling chamber and fully contacts the cooling plate, so that the cooling plate can be evenly cooled, thereby improving the cooling efficiency of the copper alloy material; 2. By setting up a scraping component, the operator can regularly scrape off the scale on the cooling plate to prevent the attached scale from affecting the cooling efficiency of the cooling water on the cooling plate, thereby improving the cooling efficiency of the copper alloy material; 3.

T-shaped blocks are fixedly provided on the top and bottom of the connecting plate 14, and the T-shaped blocks are slidably arranged in the T-shaped slots, so that the two slide plates 16 are slidably connected to the connecting plate 14. The side panels 13 , the connecting panels 14 , the baffles 15 and the slide plates 16 together form a closed box body 1 .

A molding groove 11 is also provided on the side plate 13, and the molding groove 11 on the graphite mold 2 is connected with the molding groove 11 on the side plate 13. A silicon nitride layer with high thermal conductivity, good wear resistance and corrosion resistance is provided on the inner wall of the graphite mold 2, that is, the side wall of the molding groove 11.

[0029] Reference Figure 2 and Figure 3 A cooling plate 3 is fixedly arranged inside the box 1. Two cooling plates 3 are arranged and are respectively located on the upper and lower sides of the graphite mold 2. The cooling plate 3 is made of aluminum alloy with good thermal conductivity. The graphite mold 2 is fixed in the box 1 under the abutment of the cooling plate 3, the baffle 15 and the connecting plate 14.

[0030] A cooling chamber 12 is formed between the cooling plate 3 and the slide plate 16 .

[0031] Reference Figure 4 The box body 1 is provided with a cooling assembly 4, and two groups of cooling assembly 4 are provided, and one-to-one correspondence is given to the cooling chamber 12. The cooling assembly 4 includes a water inlet pipe 41 and a water outlet pipe 42, and the water inlet pipe 41 and the water outlet pipe 42 are fixedly penetrated on the connecting plate 14 and communicated with the cooling chamber 12.

[0032] When in use, the water inlet pipe 41 and the water outlet pipe 42 are both externally connected to a chiller for providing cooling water. The cooling water enters the cooling chamber 12 through the water inlet pipe 41 and then flows back to the chiller through the water outlet pipe 42, injecting circulating cooling water into the cooling chamber 12.

[0033] During the continuous casting production of copper slabs, the copper alloy melt enters the forming tank 11, the cooling water cools the cooling plate 3, and then the cooling plate 3 exchanges heat with the copper alloy melt through the graphite mold 2, so that the copper alloy melt is cooled and crystallized. At the same time, under the action of the forming tank 11, it is formed into a copper slab and finally passes through the forming tank 11.

[0034] Reference Figure 3 and Figure 4 A guide plate 31 is fixedly provided on the cooling plate 3, and a plurality of guide plates 31 are provided. The guide plates 31 are located in the cooling chamber 12 and are all located between the water inlet pipe 41 and the water outlet pipe 42. The length direction of the guide plate 31 is the same as the relative sliding direction of the slide plate 16 and the connecting plate 14.

[0035] After the cooling water enters the cooling chamber 12, under the action of the guide plate 31, it flows in an S-shape in the cooling chamber 12, passes through various parts of the cooling chamber 12, contacts various parts of the cooling plate 3, and finally flows out from the water outlet pipe 42, so that the cooling water can cool the cooling plate 3 evenly, thereby improving the cooling efficiency of the cooling plate 3.

[0036] The guide plate 31 is also made of aluminum alloy with good thermal conductivity, and the two are made of one piece. The arrangement of the guide plate 31 increases the heat transfer area between the cooling water and the cooling plate 3, and further improves the cooling efficiency of the cooling plate 3.

[0037] Reference Figure 3 and Figure 4 , a scraping assembly 5 is provided on the box body 1, and two groups of scraping assemblies 5 are provided, and they correspond one to one with the cooling plate 3. The scraping assembly 5 includes a scraper 51 and a driving component 52. The scraper 51 is located in the cooling chamber 12, and the side of the scraper 51 close to the slide plate 16 is fixedly connected to the slide plate 16. A T-slot is provided on the side of the scraper 51 close to the cooling plate 3. A T-bar is fixedly provided on the top of the cooling plate 3, and the T-bar is adapted to the T-slot on the scraper 51. The T-bar on the top of the cooling plate 3 is inserted into the T-slot on the scraper 51, so that the scraper 51 is slidably connected to the cooling plate 3, and the sliding direction is the same as the sliding direction of the slide plate 16 relative to the connecting plate 14. A plurality of scraping grooves 511 are provided on the scraper 51, and the scraping grooves 511 correspond one to one with the guide plate 31, and the scraping grooves 511 are adapted to the guide plate 31.

[0038] Two mounting grooves 131 are provided on both side plates 13. The mounting grooves 131 are located on the side where the two side plates 13 are close to each other. The two mounting grooves 131 on the same side plate 13 correspond to the two cooling chambers 12 one by one, and the mounting grooves 131 are connected to the cooling chambers 12. Two groups of driving components 52 are provided, and are respectively located on both sides of the scraper 51. The driving components 52 correspond to the mounting grooves 131 one by one. The driving components 52 include a lead screw 521, a slider 522 and a motor 523. The lead screw 521 is rotatably arranged in the mounting groove 131, and the length direction of the lead screw 521 is the same as the sliding direction of the scraper 51. The slider 522 is slidably arranged in the mounting groove 131 and is bolted to the lead screw 521. The slider 522 is fixedly connected to one end of the scraper 51. The motor 523 is fixedly arranged on the connecting plate 14, and the output shaft of the motor 523 is coaxially fixedly connected to the lead screw 521.

[0039] After the continuous casting production continues for a certain period of time, scale is easily generated at the position where the cooling water contacts the cooling plate 3 and the guide plate 31, and the scale will reduce the cooling efficiency of the cooling water on the cooling plate 3. At this time, the operator shuts down the continuous casting machine and starts the motor 523. The motor 523 drives the lead screw 521 to rotate, and the lead screw 521 drives the slider 522 to slide in the installation groove 131, thereby driving the scraper 51 and the slide plate 16 to slide. The scraper 51 slides in the cooling chamber 12 to scrape the cooling plate 3 and the guide plate 31, so that the scale attached thereto falls off. Then the motor 523 is started to reverse, and the motor 523 drives the scraper 51 and the slide plate 16 to slide and reset through the lead screw 521 and the slider 522, and then water is injected into the cooling chamber 12 using the water inlet pipe 41, and the scale is discharged through the water outlet pipe 42 using the water.

[0040] In some other embodiments, the T-shaped bar on the top of the cooling plate 3 is also made of the same material as the cooling plate 3, which can further increase the heat transfer area between the cooling water and the cooling plate 3 and improve the cooling efficiency of the cooling plate 3. The scraper 51 can also scrape off the scale on the surface of the T-shaped bar.

[0041] Reference Figure 1 A fixing assembly 6 is provided on the box body 1 , and the fixing assembly 6 includes a dovetail bar 61 and a fixing pin 62 .

[0042] Reference Figure 4 , dovetail grooves 151 are vertically opened on both sides of the baffle 15. Two dovetail bars 61 are provided, and correspond to the side plates 13 and the dovetail grooves 151 one by one. The dovetail bars 61 are slidably arranged in the dovetail grooves 151 and are fixedly connected to the side plates 13.

[0043] Reference Figure 2 The top and bottom of the baffle 15 are provided with limiting grooves 152. Two fixing pins 62 are provided, and correspond to the slide plate 16 one by one. The fixing pins 62 are slidably arranged in the limiting grooves 152 and are fixedly connected to the slide plate 16.

[0044] When the graphite mold 2 is worn or copper billets of different sizes need to be produced, the operator uses the motor 523 to drive the slide plate 16 to slide away from the baffle 15 through the screw 521 and the slider 522, thereby driving the fixing pin 62 away from the limit groove 152. The operator then slides the baffle 15 upward relative to the dovetail bar 61, removes the baffle 15, and then takes the graphite mold 2 out of the box 1 and replaces it.

[0045] After the replacement is completed, the operator inserts the dovetail strip 61 into the dovetail groove 151, and limits the baffle 15 through the dovetail strip 61 and the dovetail groove 151, so that the baffle 15 can only slide up and down in the vertical direction relative to the side plate 13, and then uses the motor 523 to drive the slide plate 16 to drive the fixing pin 62 to reset, so that the fixing pin 62 slides into the limiting groove 152, and uses the fixing pins 62 respectively arranged at the upper and lower ends to limit the baffle 15 up and down, so that the baffle 15 and the side plate 13 are fixed.

[0046] The implementation principle of a copper slab continuous casting crystallizer device in the embodiment of the present application is: During the continuous casting of copper slabs, the molten copper alloy melt flowing out of the continuous casting machine enters the forming tank 11. At this time, the cooling water provided by the chiller enters the cooling chamber 12 through the water inlet pipe 41. Under the action of the guide plate 31, the cooling water flows in the cooling chamber 12 along an S-shape and passes through various parts of the cooling chamber 12. Then, the cooling water flows back to the chiller through the water outlet pipe 42, and the circulating cooling water is injected into the cooling chamber 12. When the cooling water flows in the cooling chamber 12, the cooling water contacts the cooling plate 3 to cool the cooling plate 3. Then, the cooling plate 3 exchanges heat with the copper alloy melt through the graphite mold 2, so that the copper alloy melt is cooled and crystallized. At the same time, under the action of the forming tank 11, the copper slab is formed and finally passes through the forming tank 11.

[0047] After the continuous casting production continues for a certain period of time, the operator shuts down the continuous casting machine and starts the motor 523. The motor 523 drives the lead screw 521 to rotate, and the lead screw 521 drives the slider 522 to slide in the installation groove 131, thereby driving the scraper 51 and the slide plate 16 to slide. The scraper 51 slides in the cooling chamber 12 to scrape the cooling plate 3 and the guide plate 31, so that the scale attached thereto falls off. Then the motor 523 is started to reverse, and the motor 523 drives the scraper 51 and the slide plate 16 to slide and reset through the lead screw 521 and the slider 522, and then water is injected into the cooling chamber 12 through the water inlet pipe 41, and the scale is discharged through the water outlet pipe 42 by the water.

[0048] When the graphite mold 2 is worn or copper billets of different sizes need to be produced, the operator uses the motor 523 to drive the slide plate 16 to slide away from the baffle 15 through the screw 521 and the slider 522, thereby driving the fixing pin 62 away from the limit groove 152. The operator then slides the baffle 15 upward relative to the dovetail bar 61, removes the slide plate 16, and then takes the graphite mold 2 out of the box 1 and replaces it.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
