Abstract
Description
Technical Field
[0001] This utility model relates to the field of temperature regulation technology, specifically to an adaptive temperature regulation device for molten steel ladles. Background Technology
[0002] The ladle is an important piece of equipment used to hold and transport molten steel in the steelmaking process. It has good high temperature resistance and corrosion resistance. In the steelmaking process, the temperature of the ladle can be adjusted to significantly improve production efficiency, product quality and process stability.
[0003] Current methods for temperature control of molten steel ladles mostly involve chemical heating or the addition of cold materials. While these methods can regulate the temperature of the molten steel ladle, they are not suitable for self-adaptive regulation. Furthermore, chemical heating may alter the composition of the molten steel, and the addition of cold materials may introduce more impurities into the molten steel. Although these methods can regulate the temperature of the molten steel inside the ladle, they all result in changes to the internal composition of the molten steel, leading to a decline in its quality. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this invention provides an adaptive temperature regulation device for molten steel ladles. It uses an infrared thermometer to measure the temperature of the molten steel inside the ladle, and employs heating or cooling components to heat or cool the ladle, thus achieving adaptive temperature regulation without the need for chemical or cooling agents, thereby ensuring the quality of the molten steel.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: a steel ladle adaptive temperature regulation device, comprising: a steel ladle body, and a protective barrel. An infrared thermometer is fixedly connected to the outer wall of the protective barrel. A heating component is fixedly connected to the outer wall of the protective barrel. A cooling component is fixedly connected to the outer wall of the heating component. The heating component includes a heat exchange box. An air inlet pipe is fixedly connected to the outer wall of the heat exchange box. A heat exchange tube is fixedly connected to the end of the air inlet pipe near the heat exchange box. A gas delivery pipe is fixedly connected to the end of the heat exchange tube away from the air inlet pipe. A burner is fixedly connected to the end of the gas delivery pipe away from the heat exchange box. Through the heat exchange box, natural gas can be preheated, allowing the heating device to perform heating operations more effectively.
[0008] Preferably, the burner nozzle penetrates the protective barrel, and the outer wall of the protective barrel is fixedly connected to the outer wall of the burner, which facilitates the heating of the molten steel ladle body by the burner.
[0009] Preferably, the cooling assembly includes a cooling box, a fan fixedly connected to the top of the cooling box, a first water pump fixedly connected to the outer wall of the cooling box, a water supply pipe fixedly connected to the outlet end of the first water pump, an annular pipe fixedly connected to the outlet end of the water supply pipe, a drain pipe fixedly connected to the end of the annular pipe away from the water supply pipe, the outlet end of the drain pipe penetrating the heat exchange box, a pumping pipe fixedly connected to the inner wall of the heat exchange box, a second water pump fixedly connected to the end of the pumping pipe away from the heat exchange box, and a spray pipe fixedly connected to the outlet end of the second water pump. The cooling assembly simplifies the cooling operation of the molten steel ladle body. Simultaneously, the combination of the spray pipe and the fan allows for rapid cooling of the hot water, promoting its recycling.
[0010] Preferably, the outer wall of the annular pipe is fixedly connected to the inner wall of the protective barrel, and the outer wall of the annular pipe is fixedly connected to the outer wall of the ladle body. After the cold water enters the annular pipe, due to the spiral arrangement of the annular pipe, the cold water will flow downward along the annular pipe and prolong the time for the cold water to absorb heat, so that the cold water cools the ladle body more fully.
[0011] Preferably, the drain pipe passes through the protective barrel, and the outer wall of the drain pipe is fixedly connected to the inner wall of the heat exchange box. The pumping end of the water pumping pipe passes through the heat exchange box, and the end of the water spraying pipe away from the second water pump passes through the cooling box and is connected to the inner wall of the cooling box. The cold water after absorbing heat becomes hot water, which increases the temperature of the heat exchange box after entering the heat exchange box, thus providing conditions for the heat exchange box to preheat the natural gas.
[0012] (III) Beneficial Effects
[0013] This invention provides a self-adaptive temperature control device for molten steel ladles. It has the following advantages:
[0014] (I) The adaptive temperature regulation device for molten steel ladle uses an infrared thermometer to measure the temperature of the molten steel inside the ladle. Based on the data from the infrared thermometer, it can activate the heating or cooling components to heat or cool the ladle, thereby achieving adaptive temperature regulation of the molten steel ladle. At the same time, it does not require the addition of chemicals or cold materials for temperature regulation, thus ensuring the quality of the molten steel.
[0015] (II) The steel ladle adaptive temperature regulation device, through the cooling component, allows hot water to enter the heat exchange box, thereby raising the temperature of the heat exchange box and preheating the natural gas. This realizes the recovery and utilization of waste heat, improves resource utilization, and allows the preheated natural gas to release more heat when burning, making the combustion more complete and enabling the heating component to perform better heating work.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-4 This utility model provides a technical solution: an adaptive temperature regulation device for molten steel ladle, comprising: a molten steel ladle body 1, and a protective barrel 2. An infrared thermometer 3 is fixedly connected to the outer wall of the protective barrel 2, a heating component 4 is fixedly connected to the outer wall of the protective barrel 2, and a cooling component 5 is fixedly connected to the outer wall of the heating component 4. The temperature of the molten steel ladle body 1 can be regulated through the heating component 4 and the cooling component 5, and the temperature of the molten steel inside the molten steel ladle body 1 can be further regulated, making the temperature regulation of the molten steel ladle simple.
[0023] The heating component 4 includes a heat exchange box 40. An air inlet pipe 41 is fixedly connected to the outer wall of the heat exchange box 40. A heat exchange tube 42 is fixedly connected to the end of the air inlet pipe 41 near the heat exchange box 40. An air supply pipe 43 is fixedly connected to the end of the heat exchange tube 42 away from the air inlet pipe 41. A burner 44 is fixedly connected to the end of the air supply pipe 43 away from the heat exchange box 40. The nozzle of the burner 44 penetrates through the protective tank 2. The outer wall of the protective tank 2 is fixedly connected to the outer wall of the burner 44. After absorbing heat, cold water flows into the heat exchange box 40, which raises the temperature inside the heat exchange box 40, thereby preheating the natural gas, realizing the recovery and utilization of waste heat, and improving resource utilization.
[0024] The cooling assembly 5 includes a cooling box 50. A fan 58 is fixedly connected to the top of the cooling box 50. A first water pump 51 is fixedly connected to the outer wall of the cooling box 50. A water supply pipe 52 is fixedly connected to the outlet end of the first water pump 51. An annular pipe 53 is fixedly connected to the outlet end of the water supply pipe 52. A drain pipe 54 is fixedly connected to the end of the annular pipe 53 away from the water supply pipe 52. The outlet end of the drain pipe 54 passes through a heat exchange box 40. A suction pipe 55 is fixedly connected to the inner wall of the heat exchange box 40. A second water pump 56 is fixedly connected to the end of the suction pipe 55 away from the heat exchange box 40. A spray pipe 57 is fixedly connected to the outlet end of the second water pump 56. The outer wall of the annular pipe 53 is connected to a protective... The inner wall of the barrel 2 is fixedly connected, the outer wall of the annular pipe 53 is fixedly connected to the outer wall of the ladle body 1, the drain pipe 54 passes through the protective barrel 2, the outer wall of the drain pipe 54 is fixedly connected to the inner wall of the heat exchange box 40, the pumping end of the water pumping pipe 55 passes through the heat exchange box 40, and the end of the spray pipe 57 away from the second water pump 56 passes through the cooling box 50 and is connected to the inner wall of the cooling box 50. Through the annular pipe 53, the time for cold water to absorb heat is increased, making the cooling effect of cold water on the ladle better. Hot water is sprayed out through the spray pipe 57, and with the fan 58, the hot water can be cooled quickly, promoting the recycling of hot water. At the same time, it makes the cooling work of the ladle simple.
[0025] Working principle: Observe the infrared thermometer 3 on the outer wall of the protective barrel 2. If the temperature of the molten steel inside the ladle body 1 is too high, the ladle can be cooled by the cooling component 5. If the temperature of the molten steel is too low, the ladle body 1 can be heated by the heating component 4. This completes the adaptive temperature regulation of the ladle body 1, making the temperature regulation of the ladle simple.
[0026] During use, if the infrared thermometer 3 indicates that the molten steel temperature is too high, the first water pump 51 is activated, drawing out the cold water inside the cooling tank 50 and sending it through the water pipe 52 into the annular pipe 53. This causes the cold water to flow downwards along the annular pipe 53, absorbing heat from the ladle body 1 and lowering its temperature. Consequently, the temperature of the molten steel inside the ladle body 1 decreases. The cooled water, having absorbed its heat, flows out from the drain pipe 54 and enters the heat exchanger 40, raising the temperature inside the heat exchanger 40. Then, the second water pump 56 is activated to... Hot water inside the heat exchange box 40 is sent to the spray pipe 57 through the pump pipe 55. The hot water is sprayed into the cooling box 50 by the nozzle at the bottom of the spray pipe 57, increasing the contact area between the hot water and the air, so that the hot water cools down quickly. Then the fan 58 is started to increase the air circulation speed between the inside of the cooling box 50 and the outside, further accelerating the cooling speed of the hot water and completing the recycling and reuse of cold water. This makes the cooling of the molten steel ladle simple. At the same time, the recycling and reuse of hot water improves the resource utilization rate and reduces the waste of resources.
[0027] If the temperature of the molten steel displayed by the infrared thermometer 3 is low, natural gas is first introduced into the air inlet pipe 41. When the natural gas passes through the heat exchange tube 42, it absorbs the heat inside the heat exchange box 40, causing the temperature of the natural gas inside the heat exchange tube 42 to rise, thus completing the preheating of the natural gas. Subsequently, the natural gas is sent to the burner 44 through the gas supply pipe 43 for combustion, heating the ladle body 1 and completing the heating of the ladle. Preheating the natural gas allows it to release more heat during combustion, improving the heating efficiency of the heating component 4 on the ladle body 1.
[0028] It is worth noting that the infrared thermometer 3 in the above embodiments can be an Optris CTlaser 3M, and the burner 44 can be an HRQ-80 high-speed gas burner. Both operate using methods commonly used in the prior art.
