Description

Technical Field

[0001] The utility model relates to the technical field of converter equipment for reducing the tapping temperature, in particular to a converter equipment for reducing the tapping temperature. Background Art

[0002] The converter is the first step in steelmaking, and it's also where the transformation of iron into steel begins. Depending on where the gas (primarily oxygen) is blown into the converter, converters are categorized into top-blowing, bottom-blowing, and combined top-and-bottom blowing. Combined blowing is used by most steel mills. For example, after oxygen is blown from the top, argon is blown from the bottom. This allows the carbon content in the molten steel to reach 0.01%, which is particularly important for the smelting of automotive steel, thin plate steel, and electrical steel. Existing converters still have some drawbacks, such as:

[0003] For example, a converter device for reducing the steel tapping temperature with announcement number CN221479966U, when used, includes: a bottom plate, two support plates fixedly installed on both sides of the top of the bottom plate, and a rotating shaft fixedly installed on one side of the support plate. The utility model drives the converter body to rotate by rotating the rotating shaft, pouring out the molten steel inside the converter body, and the molten steel is guided by three guide plates to cool the molten steel. The molten steel is guided to the middle by two guide plates on both sides above the guide plate, so that the molten steel is cooled during the flow process. The stepped discharge of the three guide plates allows the molten steel to automatically fall and fully contact with the air, so as to facilitate cooling of the molten steel. Since the outer side of the guide plate is blocked by the support plate and the connecting plate, the guide plate presents a semi-enclosed structure, which slows down the cooling speed of the molten steel. There are some problems with the above device. Although the device can be used well to reduce the temperature of the steel tapping, it is cooled by multiple guide plates and fans during use. However, the heat loss is usually large during the heating process during use, which is not convenient for recovering the heat for secondary use, making it difficult for the use effect of the converter equipment to meet the established expectations. Therefore, we propose a converter equipment device for reducing the steel tapping temperature to solve the above problems. Utility Model Content

[0021] When in use, the raw materials are added to the furnace body 7 and heated. At this time, the push rod 9 is started to drive the first slider 10 to slide inside the frame 2. At this time, the first slider 10 drives the first support rod 11 to adjust. At the same time, the first support rod 11 drives the second support rod 12 to adjust through the hinge shaft. At this time, the second support rod 12 drives the second slider 13 to slide inside the furnace cover 14, driving the furnace cover 14 to be lowered, and the furnace body 7 is closed. During the heating process, the exhaust fan 19 inside the exhaust hole 18 can be used to remove the exhaust gas produced during the heating of the furnace body 7. After the excess heat is drawn into the exhaust pipe 20, it is input into the air supply pipe 21 through the exhaust pipe 20. At this time, the air supply pipe 21 heats the water inside the water tank 22, and then pumps the heated water through the water supply pipe 23. At this time, the hot water flows inside the water supply pipe 23 and then returns to the water tank 22. At the same time, the water supply pipe 23 preheats the oxygen inside the oxygen tank 17, and then injects the oxygen into the oxygen blowing head 15 through the oxygen supply pipe 16, and then enters the interior of the furnace body 7, thereby improving the combustion efficiency of the fuel in the furnace and making the combustion more complete. By increasing the oxygen supply, the temperature can be increased, the heat can be increased, and thus the smelting process can be accelerated. Since the oxygen is preheated in advance, the subsequent use effect is better.

At this time, the atomizing nozzles 27 on both sides of the frame 2 are used to spray atomized water mist to reduce the temperature of the molten steel. After the temperature is reduced, the worm 4 can be driven to rotate by the first motor 3. Since the worm 4 and the worm gear 5 are engaged, the worm gear 5 drives the rotating rod 6 to rotate. At the same time, the rotating rod 6 drives the furnace body 7 to adjust, so that after the angle of the furnace body 7 is tilted, the internal molten steel is discharged through the steel outlet on the surface.

[0022] An atomizing nozzle 27 is provided inside the frame 2, an infrared temperature sensor 24 is provided above the base 1, and a guide plate 25 and an exhaust fan 26 are provided inside the base 1;

When the temperature is too high, the exhaust fan 26 inside the base 1 is started to cool the molten steel flowing above the guide plate 25 for a second time.

[0024] Working principle: When using a converter device that reduces the tapping temperature, the raw materials are added to the furnace body 7 and heated. At this time, the push rod 9 is started to drive the first slider 10 to slide inside the frame 2. At this time, the first slider 10 drives the first support rod 11 to adjust. At the same time, the first support rod 11 drives the second support rod 12 to adjust through the hinge shaft. At this time, the second support rod 12 drives the second slider 13 to slide inside the furnace cover 14, and drives the furnace cover 14 to be lowered, closing the furnace body 7. During the heating process, the exhaust fan 19 inside the exhaust hole 18 can be used to exhaust air. After the excess heat generated during the heating process of the furnace body 7 is drawn into the exhaust pipe 20, it is input into the air supply pipe 21 through the exhaust pipe 20. At this time, the air supply pipe 21 heats the water inside the water tank 22, and then pumps the heated water through the water supply pipe 23. At this time, the hot water flows inside the water supply pipe 23 and then returns to the water tank 22. At the same time, the water supply pipe 23 preheats the oxygen inside the oxygen box 17, and then injects the oxygen into the oxygen blowing head 15 through the oxygen supply pipe 16, and then enters the interior of the furnace body 7, thereby improving the combustion efficiency of the fuel in the furnace and making the combustion more complete. By increasing the oxygen supply, the temperature can be increased, the heat can be increased, and the smelting process can be accelerated. Since the oxygen is preheated in advance, the subsequent use effect is better. When the heating is completed, the internal temperature is detected by the temperature detector 8 inside the furnace body 7. When the temperature is too high, the speed of the exhaust fan 19 is increased to quickly extract the internal heat. When the extraction efficiency of the exhaust fan 19 is low, the lifting mechanism is started to open the furnace cover 14. At this time, the atomizing nozzles 27 on both sides of the frame 2 spray atomized water mist to reduce the temperature of the molten steel. After the temperature is reduced, the worm 4 can be driven to rotate by the first motor 3. Since the worm 4 It meshes with the worm gear 5. At this time, the worm gear 5 drives the rotating rod 6 to rotate, and at the same time, the rotating rod 6 drives the furnace body 7 to adjust, so that after the angle of the furnace body 7 is tilted, the internal molten steel is discharged through the steel outlet on the surface. At this time, the molten steel is guided by the inclined guide plate 25 inside the base 1. At the same time, the infrared temperature sensor 24 detects the temperature of the molten steel discharged through the steel outlet. When the temperature is too high, the exhaust fan 26 inside the base 1 is started to perform secondary cooling on the molten steel flowing above the guide plate 25, thereby completing a series of tasks. The content not described in detail in this specification belongs to the existing technology known to professional and technical personnel in this field.
