Description

Technical Field

[0001] The present invention relates to the technical field of continuous casting equipment, and particularly to a mold with a high cooling heat exchange rate. Background Art

[0002] During the production and manufacturing of copper ingots, molten copper is poured into a mold, and at the same time, the molten copper in the mold is cooled to solidify the molten copper. Then, a stretching or telescopic device is used to carry and pull the solidified copper ingot at the bottom opening of the mold to realize the process of continuously casting copper water into a copper ingot; most of the cooling water in the mold adopts a closed-loop circulation. The cooling water is pressurized by a water pump and supplied to the mold. The return water enters the heat exchanger for cooling by residual pressure and then is pressurized by the pump for recycling.

[0003] The traditional coolant delivery method is continuous at a certain rate. And since the coolant is always in a flowing state during the delivery process, the cooling liquid at the inlet end is continuously heated during the movement, resulting in the gradual increase of its temperature as the liquid flows. By the time it moves to the outlet end, the cooling effect of the liquid drops significantly, causing uneven cooling efficiency at the inlet and outlet ends of the mold, resulting in inconsistent cooling effects for the continuous parts between the molten copper liquids in the casting during solidification, with a large temperature difference, affecting the cooling and forming of the copper ingot and the quality of the finished copper ingot.

[0004] Domestic related research has achieved efficient cooling of the casting liquid by placing the cooling device inside the mold. Among them, the patent document publication number is: CN106180604B, which discloses a mold structure and a cooling method inside the mold. It places the cooling device inside the mold and transports the cooling liquid through the inlet pipe, the intermediate connecting pipe, and the outlet pipe to achieve the cooling process from the inside to the outside; however, in the above method, the cooling liquid still continuously flows in the cooling device, and the cooling liquid gradually warms up during the flowing process. After the cooling liquid warms up, it is impossible to achieve a predetermined consistent cooling effect, which also leads to inconsistent heat dissipation effects at the inlet and outlet ends of the cooling device and a large temperature gradient, and it is impossible to achieve uniform cooling of each part of the casting liquid. Summary of the Invention

[0005] In view of the above problems, the present invention provides a mold with a high cooling heat exchange rate, and the invention solves the problems of how to improve the heat exchange rate of the mold and ensure relatively consistent cooling rates for the upper, lower, and surrounding parts of the mold.

[0006] To solve the above problems, the technical solution adopted by the present invention is:

The opening corresponds to the first cooling pipe and the second cooling pipe and is connected at both ends. The water channel control component controls the alternating opening and closing of the first cooling pipe and the second cooling pipe to complete the rapid delivery of the cooling liquid. By setting the first cooling pipe and the second cooling pipe, the first cooling pipe is closed to absorb heat while the second cooling pipe quickly replaces the cooling liquid to prepare for subsequent cooling. The two are continuously alternated, ensuring that the cooling rate of different positions of the copper liquid is consistent, and the cooling rate can also be guaranteed to meet the requirements, thereby ensuring the quality of the copper ingot after forming; simply accelerating the delivery rate of the liquid in one pipe to achieve cooling, the delivery rate of the liquid is difficult to adjust according to actual conditions, which will cause the coolant at the end to be discharged from the pipeline before fully realizing heat exchange; if the liquid is delivered too slowly, the cooling liquid will flow to the end and the cooling effect will decrease. The above-mentioned setting method and control method can effectively solve the above-mentioned problems.

[0008] Preferably, the cross-sections of the first cooling pipe and the second cooling pipe are both flat and close to the outer surface of the crystallizer body. By setting the pipes in the above shape, the heat absorption area can be increased, the heat exchange rate can be further improved, and the cooling effect can be ensured.

[0009] Preferably, the cooling pipes are arranged in two groups, and the two groups of cooling pipes are arranged in the cooling channel. The liquid inlet ends of the two groups of cooling pipes are respectively arranged at the upper and lower ends. By arranging the above components, the cooling rates of the upper and lower ends of the crystallizer body are further guaranteed to be consistent, and the consistency of the overall cooling rate of the copper ingot during the cooling process is guaranteed, thereby ensuring the quality of the finished copper ingot.

[0010] Preferably, the waterway control assembly includes a control block, a control chamber is formed on the inner wall of the control block, two delivery ports are arranged on the inner wall of the first side of the control chamber, the two delivery ports are respectively communicated with the first cooling pipe and the second cooling pipe, the waterway control interface is communicated with the second side of the control chamber, a control baffle is hermetically and slidably connected in the control chamber, a control opening is formed on the surface of the control baffle, and by adjusting the control opening to be in different positions, the connection of the first cooling pipe or the second cooling pipe can be realized. The above control assembly can effectively control the waterway, and the above setting method can withstand the high-temperature environment around the mold and can work stably and efficiently for a long time.

[0011] Preferably, the two waterway control assemblies are both located on the same side, and a driving assembly is arranged between the two waterway control assemblies for driving the two control baffles to move synchronously.

[0012] Preferably, the driving assembly includes a driving pipe, a driving piston is slidably connected to the inner wall of the driving pipe, driving rods are fixedly connected to both side walls of the driving piston, the ends of the driving rods penetrate through the driving pipe and are fixedly connected to the control baffle, and the driving piston divides the driving pipe into a first driving chamber and a second driving chamber. By controlling the pressure in the first driving chamber and the second driving chamber, the driving piston can be controlled to be in different positions.

[0013] Preferably, both the first driving chamber and the second driving chamber are communicated with an oil control pipeline, and the oil control pipeline is externally connected to an oil control device.

[0014] Preferably, the first driving chamber is communicated with the first cooling pipe through a first connecting pipe, and the second driving chamber is communicated with the second cooling pipe through a second connecting pipe. By setting the above connection method, automatic position change of the driving piston during the heat exchange process is realized, and automatic control is achieved.

[0015] Preferably, a limiting element is fixedly connected to the side wall of the side baffle, and two limiting protrusions adapted to the limiting element are arranged on the outer wall of the driving rod. Through the above setting method, the driving piston can drive the control baffle to quickly change positions, realizing the quick position change of the waterways of the first cooling pipe and the second cooling pipe, and ensuring the heat exchange efficiency.

[0016] Preferably, a limiting channel is formed on the side wall of the side baffle, the waterway control interface is fixedly installed outside the limiting channel through a first installation workpiece, and the driving assembly is fixedly installed outside the limiting channel through a second installation workpiece.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. By arranging the first cooling pipeline and the second cooling pipeline in the cooling channel and controlling the intermittent opening and closing of the first cooling pipeline and the second cooling pipeline through the waterway control component, the cooling liquid can quickly enter the first cooling pipeline and the second cooling pipeline to cool the copper ingot. Compared with the traditional single pipeline continuously inputting the cooling liquid, due to the rapid intermittent input of the cooling liquid, the cooling effects on the four sides and the upper and lower ends of the copper ingot tend to be consistent, ensuring the consistency and stability of the cooling effect of the copper ingot. While the first cooling pipeline is closed to absorb heat, the second cooling pipeline quickly replaces the cooling liquid to prepare for subsequent cooling. The two processes alternate continuously, ensuring that the cooling rates at different positions of the copper liquid are consistent and that the cooling rate meets the requirements, guaranteeing the quality of the copper ingot after forming; the first cooling pipeline and the second cooling pipeline are arranged in flat plate shapes, which can increase the heat absorption area of the cooling pipeline and achieve better heat dissipation and cooling effects; by setting high-pressure water flow into the cooling pipeline, when the first cooling pipeline and the second cooling pipeline with intermittent opening and closing are subjected to a suddenly increased water flow pressure, the water flow rate suddenly increases, which can carry away the sediment in the flat pipeline and avoid pipeline blockage, ensuring the stability of the cooling water transportation.

[0019] 2. By arranging components such as the waterway control component and the control baffle, the intermittent opening and closing of the first cooling pipeline and the second cooling pipeline can be controlled efficiently and stably. By arranging the driving component, the two control baffles can be driven to move synchronously, realizing the closing of both ends of the first cooling pipeline or the second cooling pipeline. And by arranging the first driving chamber and the second driving chamber to communicate with the first cooling pipeline and the second cooling pipeline respectively, the position of the driving piston can be automatically controlled according to the temperature in the water pipe, ensuring the timeliness and stability of the cooling water transportation and realizing an automatic control process, which is automatic and efficient.

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] Refer to Figure 1-7 , a mould with a high cooling heat exchange rate, comprising a mould body 1. The top of the mould body 1 is provided with a top plate 101. A vertically arranged crystallization channel 103 is formed between the top plate 101 and the mould body 1. During the casting process, the molten copper passes through the crystallization channel 103 to be cooled and formed. The molten copper at the bottom end of the crystallization channel 103 solidifies into a copper ingot, moves downward at a predetermined rate, and the upper end continuously casts molten copper, finally completing the production and processing of strip-shaped copper ingots; a side baffle 102 fixedly connected to the top plate 101 is arranged outside the mould body 1. A cooling channel 104 is formed between the side baffle 102 and the mould body 1. A cooling pipeline is arranged in the cooling channel 104. The cooling pipeline is externally connected to a liquid pumping device to continuously transport the cooling water through the cooling pipeline. When the cooling liquid is transported into the cooling channel 104, it can absorb the surrounding heat, thereby realizing the cooling and temperature reduction of the molten copper, accelerating the cooling and hardening of the molten copper, and speeding up the production rate of the copper ingot.

[0030] The cooling pipes include the serpentine first cooling pipe 201 and the serpentine second cooling pipe 202. A waterway control interface is fixedly installed on the side wall of the side baffle 102. The waterway control interface includes a first water pipe interface 301 and a second water pipe interface 302. The first ends of the first cooling pipe 201 and the second cooling pipe 202 are communicated with the first water pipe interface 301, and the second ends of the first cooling pipe 201 and the second cooling pipe 202 are communicated with the second water pipe interface 302. Cooling water enters from one end of the first water pipe interface 301 or the second water pipe interface 302, is transported through the first cooling pipe 201 and the second cooling pipe 202, fills the pipes, and finally the cooling liquid is discharged from the other end to realize the circulating transportation of the cooling liquid. A waterway control component 5 is arranged on one side of the side baffle 102. By controlling the intermittent conduction of the first cooling pipe 201 and the second cooling pipe 202 through the waterway control component 5, the high-pressure cooling water externally connected to the waterway control interface can quickly fill the first cooling pipe 201 or the second cooling pipe 202, realize the replacement of the heated cooling liquid inside, and ensure the relative consistency of the cooling rate around and on the upper and lower sides of the mold body 1.

[0031] There are two groups of waterway control components 5. The two groups of waterway control components 5 correspond to the first water pipe interface 301 and the second water pipe interface 302 respectively and are connected to both ends of the first cooling pipe 201 and the second cooling pipe 202. By controlling the alternate opening and closing of the first cooling pipe 201 and the second cooling pipe 202 through the waterway control component 5, the rapid transportation of the cooling liquid is completed. Since the first cooling pipe 201 and the second cooling pipe 202 are externally connected to a high-pressure pump water device, when the first cooling pipe 201 is in the conducting state and the second cooling pipe 202 is in the closed state, at this time, the high-pressure water flow quickly fills the first cooling pipe 201, and can quickly replace the residual heated liquid in the first cooling pipe 201. The cooling liquid quickly fills the entire first cooling pipe 201. Compared with the traditional continuous transportation of the cooling liquid, it can make the cooling liquid at the end of the first cooling pipe 201 still have sufficient cooling capacity to ensure the relatively consistent cooling rate around and at the upper and lower ends of the mold body 1, maintain a higher heat exchange rate, ensure the rapid cooling of the copper ingot, and ensure the quality of the finished copper ingot.

[0032] And because the rate of the input water source is large, the rate of the cooling water transported in the pipes is large. When sediment substances are generated after the liquid in the pipes is heated, the high-speed flowing liquid can timely transport and carry away the generated sediment substances, avoiding blockage in the pipes, ensuring the normal flow rate of the water flow, ensuring the stable cooling of the cooling water, and also improving the quality of the finished copper ingot.

[0033] As one of the preferred ways of the cooling pipeline, the cross-sections of the first cooling pipeline 201 and the second cooling pipeline 202 are both flat. The first cooling pipeline 201 and the second cooling pipeline 202 are closely attached to the outer surface of the crystallizer body 1. The flat shape can be set as a rectangle, and the side with a larger area of the rectangular pipeline faces the crystallizer body 1, which can increase the heat absorption area, further improve the heat exchange rate, and ensure the cooling effect.

[0034] There are two groups of cooling pipelines, and both groups of cooling pipelines are arranged in the cooling channel 104. The liquid inlet ends of the two groups of cooling pipelines are respectively arranged at the upper and lower ends. By setting two groups of cooling pipelines, whose liquid inlet ends are located at the upper and lower ends of the crystallizer body 1, it further ensures the consistency of the cooling rates at the upper and lower ends of the crystallizer body 1, ensures the consistency of the overall cooling rate of the copper ingot during the cooling process, and ensures the quality of the finished copper ingot.

[0035] As one of the optional control methods, the waterway control component 5 includes a control block 501. There is a control chamber 502 opened on the inner wall of the control block 501. Two delivery ports 503 are arranged on the inner wall of the first side of the control chamber 502. The two delivery ports 503 are respectively communicated with the first cooling pipeline 201 and the second cooling pipeline 202. The waterway control interface is communicated with the second side of the control chamber 502. A control baffle 505 is hermetically and slidably connected in the control chamber 502. The end of the control baffle 505 penetrates through the control chamber 502 and is hermetically slidable therewith. The two sides of the first cooling pipeline 201, the second cooling pipeline 202 and the waterway control interface can be relatively sealed by the control baffle 505. The control baffle 505 functions as a baffle to block the flow of the cooling liquid; a control opening 504 is opened on the surface of the control baffle 505. By adjusting the control opening 504 to different positions, the connection of the first cooling pipeline 201 or the second cooling pipeline 202 can be realized. By adjusting the control baffle 505 to different positions, making the control opening 504 face one of the delivery ports 503, the corresponding pipeline is in a conducting state after facing each other, and the control of the cooling water can be realized to ensure the normal flow of the cooling water.

[0036] Both of the two waterway control components 5 are located on the same side. A driving component 4 is arranged between the two waterway control components 5 to drive the two control baffles 505 to move synchronously. By driving the two control baffles 505 to move synchronously through the driving component 4, efficient and stable control can be realized. The two ends of the first cooling pipeline 201 or the second cooling pipeline 202 can be partitioned and blocked by the control baffle 505, making the corresponding pipeline in a closed state, allowing the cooling liquid to stay for a while, and realizing the rapid absorption of the heat around the crystallizer body 1 and at the upper and lower ends.

[0037] As an optional driving element, the driving assembly 4 includes a driving tube 401. A driving piston 402 is slidably connected to the inner wall of the driving tube 401. Driving rods 403 are fixedly connected to both side walls of the driving piston 402. The ends of the driving rods 403 penetrate through the driving tube 401 and are fixedly connected to the control baffle 505. The driving piston 402 divides the driving tube 401 into a first driving chamber and a second driving chamber. By controlling the pressure in the first driving chamber and the second driving chamber, the driving piston 402 is controlled to be in different positions. By controlling the pressure in the corresponding chamber, the driving piston 402 and the driving rods 403 are pushed to be in different positions, so as to control the position of the control baffle 505 and achieve an efficient control process.

[0038] As an optional driving method, both the first driving chamber and the second driving chamber are connected to oil control pipelines. The oil control pipelines are externally connected to oil control equipment. By controlling the oil pressure in the first driving chamber and the second driving chamber through the oil control equipment, the position of the driving piston 402 can be controlled efficiently and accurately, so as to complete accurate and efficient waterway control and ensure normal heat exchange.

[0039] As another optional driving method, the first driving chamber is connected to the first cooling pipeline 201 through a first connecting pipeline, and the second driving chamber is connected to the second cooling pipeline 202 through a second connecting pipeline. When the first cooling pipeline 201 is in a conducting state and the second cooling pipeline 202 is in a closed state, the cooling liquid in the first cooling pipeline 201 expands when heated, and its internal pressure increases, which can increase the pressure in the first driving chamber. At this time, the second driving chamber is in communication with the second cooling pipeline 202, and the second cooling pipeline 202 is in a connected state. The liquid in the second driving chamber can flow freely, thereby pushing the driving piston 402 to move from the first position to the second position. At this time, the control baffle 505 is repositioned, realizing that the first cooling pipeline 201 is in a conducting state, and the internal cooling liquid can be quickly replaced. After repositioning, the second cooling pipeline 202 is in a closed state, and the subsequent working process is cycled, realizing the automatic repositioning of the driving piston 402 during the heat exchange process and achieving automatic control. A limiting element 404 is fixedly connected to the side wall of the side baffle 102. Two limiting protrusions adapted to the limiting element 404 are arranged on the outer wall of the driving rod 403. The limiting element 404 and the limiting protrusions can be relatively matched to limit the position of the driving rod 403. Only when a sufficient force acts can the driving rod 403 be pushed to break away from the restriction of the limiting element 404 and achieve repositioning; through the above setting method, the driving piston 402 can drive the control baffle 505 to quickly reposition, realizing the quick repositioning of the waterways of the first cooling pipeline 201 and the second cooling pipeline 202, ensuring the heat exchange efficiency. The above limiting element 404 belongs to the prior art and does not involve improvements, so it will not be elaborated here.

[0040] A limiting channel 1021 is opened on the side wall of the side baffle 102. Components such as the first cooling pipe 201 and the second cooling pipe 202 can enter and exit through the limiting channel 1021 to achieve rapid installation. Among them, the waterway control interface is installed and fixed on the outside of the limiting channel 1021 through the first installation workpiece 303, and the driving component 4 is installed and fixed on the outside of the limiting channel 1021 through the second installation workpiece 405, ensuring the stability of the two, realizing the normal control process, and being convenient for installation and fixation, improving the installation efficiency.

[0041] During the working process of the present invention, the cast molten copper is poured into the crystallization channel 103 to be cooled, and it solidifies to form a copper ingot. The solid copper ingot moves downward at a certain rate, and the molten copper at the upper end gradually solidifies to form a continuous copper ingot.

[0042] The cooling pipes are arranged outside the crystallizer body 1 to complete the cooling of the molten copper and make it solidify to form a copper ingot. During the water cooling process, by controlling the reciprocating movement of the driving piston 402, it can drive the control baffles 505 on both sides to reciprocate. By controlling the regular cyclic reciprocating movement of the driving piston 402, the control openings 504 on the control baffles 505 are adjusted to be in different positions, respectively opposite to the two conveying ports 503, to control the opening and closing of the first cooling pipe 201 or the second cooling pipe 202.

[0043] When the first cooling pipe 201 is in a conducting state and the second cooling pipe 202 is in a closed state, at this time, high-pressure cooling water can be quickly injected into the first cooling pipe 201 to displace the heated cooling liquid in the first cooling pipe 201. And after the displacement process ends, the cooling liquid in the second cooling pipe 202 is heated synchronously. When it reaches the predetermined temperature, at this time, the second cooling pipe 202 is controlled to be in a conducting state, and the first cooling pipe 201 is in a closed state at this time. Similarly, at this time, the cooling liquid in the first cooling pipe 201 cools down the crystallizer body 1, and the heated cooling liquid in the second cooling pipe 202 is quickly displaced.

[0044] The above process is a rapid circulation process during the copper casting process, which can achieve rapid cooling of the upper and lower ends and the periphery of the crystallizer body 1, ensure the consistency of the cooling rate of the copper ingot during the copper casting process, and ensure the quality of the copper ingot finished product.

[0045] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
