Description

Technical Field

[0001] This invention relates to the field of steelmaking furnace mouth cleaning technology, and more specifically to a high-efficiency furnace cleaning and tamping device for solidified slag at the steelmaking furnace mouth. Background Technology

[0002] During steelmaking, the furnace mouth area of ​​steelmaking furnaces (such as converters and electric furnaces) is constantly exposed to high temperatures, splashes, and dust. Molten steel slag or splashes easily solidify on the inner wall and end face of the furnace mouth, forming a hard, highly adhesive solidified slag layer. As the number of smelting furnaces increases, the solidified slag accumulates and thickens, leading to a reduction in the effective diameter of the furnace mouth, affecting the efficiency of adding molten iron, scrap steel, and flue gas emissions. In severe cases, it can even cause furnace mouth blockage, forcing the production line to shut down for cleaning. Currently, common cleaning methods include manual hammering with long chisels or sledgehammers, simple mechanical impact crushing, and using a furnace tamping machine to push the top. However, manual hammering is extremely labor-intensive and inefficient, and the high temperature radiation and slag splashes at the furnace mouth pose serious safety hazards. Simple mechanical impact often only breaks up parts of the slag, making it difficult to evenly peel off the entire ring of solidified slag. Often, some areas have detached while the roots remain firmly stuck together, requiring repeated operations and causing additional mechanical damage to the furnace mouth itself. Although the tamping machine can provide a large thrust, when directly pushing the entire solidified slag, due to the high overall strength of the slag layer and the large adhesion area with the furnace mouth substrate, it often requires a great force, which can easily lead to furnace mouth deformation or cracking of refractory materials.

[0003] To address the aforementioned issues, existing technologies attempt to use a unidirectional rotary cutting tool to cut the slag layer at the furnace mouth. However, in actual working conditions, the solidified slag at the furnace mouth typically presents as an irregular ring-shaped accumulation, distributed on the inner wall, outer wall, and end face, with significant differences in slag layer thickness and hardness in different areas. A single circumferential cutting method can only create a few annular grooves on the slag layer surface, failing to sever the overall bond between the slag layer and the furnace mouth. In particular, the longitudinal bonding force along the furnace mouth axial direction remains, requiring considerable external force to detach the slag after cutting. Furthermore, large fragments are easily generated during detachment, potentially injuring equipment below or operators. In addition, existing cutting and hammering processes are often separated, with one set of equipment first making the cut and then switching to another set of tools for hammering. This not only increases equipment costs and operating time but also makes it difficult to guarantee the alignment accuracy of the two operations, often resulting in the hammering point deviating from the cut position and leading to unsatisfactory peeling results.

[0004] Therefore, there is an urgent need for a furnace tamping device that can efficiently and safely clean solidified slag at the furnace mouth of steelmaking furnaces. It should be able to simultaneously perform multi-directional and uniform depth cutting operations, and smoothly transition to the slag removal process by hammering without changing tools. Furthermore, it should maintain transmission reliability and synchronization throughout the radial adjustment of the cutting wheel, thereby completely solving the problems of low efficiency, damage to the furnace mouth, and incomplete slag removal of existing cleaning methods.

The cross-sectional dimensions of the rotating circular groove and the diagonal cross-sectional dimensions of the convex limiting block are clearance-fitted.

[0015] The technical effects and advantages of this invention are as follows: 1. In cleaning the solidified slag at the furnace mouth of a steelmaking furnace, the present invention first inserts a transmission positioning shaft into the furnace mouth, then drives a rotating shaft to rotate via a fourth servo motor, which in turn drives a second transmission wheel and a first bevel gear to rotate. The second bevel gear rotates through the engagement between the transmission positioning block and the connecting transmission groove, thereby causing the connecting column and the cutting wheel to rotate. Then, all the cutting wheels rotate through the transmission belt and guide. Simultaneously, the first servo motor drives the transmission positioning shaft to rotate, which in turn drives the push plate assembly and the solidified slag cleaning assembly to rotate synchronously. Then, the third servo motor drives the transmission gear to rotate, and the meshing of the transmission gear and the transmission teeth drives the push plate body to rotate relative to the guide plate assembly. The arc-shaped push groove pushes the solidified slag cleaning assembly to spread outward under the guidance of the first guide groove and the first guide rod, cutting the surface of the solidified slag at the furnace mouth. Cutting is then performed at intervals at the furnace mouth, and annular grooves are uniformly cut into the surface of the solidified slag at the furnace mouth, facilitating the subsequent knocking of the solidified slag off the furnace mouth. 2. In this invention, the second servo motor drives the third U-shaped positioning plate to rotate 90 degrees, so that the teeth on the outer side of the second bevel gear mesh with the teeth on the outer side of the first bevel gear. Then, the fourth servo motor drives the cutting wheel to rotate, and the third servo motor drives the transmission gear to rotate. The meshing of the transmission gear and the transmission teeth drives the circular plate body to rotate. The arc-shaped pushing groove pushes the solidified slag cleaning component to spread outward under the guidance of the first guide groove and the first guide rod. Then, the hydraulic rod drives the furnace mouth cleaning device to rise and fall, so as to longitudinally cut the solidified slag at the furnace mouth of the steelmaking furnace, which facilitates the subsequent knocking down of the solidified slag at the furnace mouth. 3. After the slit cutting work is completed on the solidified slag at the furnace mouth of the present invention, the user pulls the handle upward, causing the convex limiting block to slide inside the convex sliding groove until the convex limiting block slides into the rotating circular groove. Then, the user rotates the handle, causing the handle and the striking positioning post to rotate 90 degrees along the convex limiting block and be locked in the rotating positioning groove. Then, the first bevel gear rotates, driving the cutting wheel to rotate, which in turn drives the handle to rotate and strike the solidified slag at the furnace mouth of the steelmaking furnace, thereby causing the solidified slag at the furnace mouth of the steelmaking furnace to fall off. Since the surface of the solidified slag at the furnace mouth of the steelmaking furnace has been cut with cracks, the solidified slag at the furnace mouth of the steelmaking furnace can fall off quickly during the process of striking by pulling the handle. 4. When the circular plate body is rotated and the solidified slag cleaning component moves outward, the spring is stretched under the pull of the transmission belt, which in turn drives the first sliding cylinder to slide outside the second guide rod. As the solidified slag cleaning component spreads outward, the first sliding cylinder will spread outward synchronously, which makes it easier to ensure that the transmission belt effectively transmits power to the second transmission wheel.

When cleaning the solidified slag at the furnace mouth of a steelmaking furnace, the moving positioning shaft 502 is first extended... The material enters the furnace mouth of the steelmaking furnace, and then the fourth servo motor 509 drives the rotating shaft 5055 to rotate, which in turn drives the second transmission wheel 5056 and the first bevel gear 5059 to rotate. Through the cooperation between the transmission positioning block 50511 and the connecting transmission groove 505810, the second bevel gear 50583 is driven to rotate, thereby causing the connecting column 50582 and the cutting wheel 50585 to rotate. Then, through the transmission belt 506 and the guide 3039, all the cutting wheels 50585 are driven to rotate. At the same time, the first servo motor 501 drives the transmission positioning shaft 502 to rotate, which in turn drives the pusher plate assembly 504 and the solidified slag. The cleaning component 505 rotates synchronously, and then the third servo motor 507 drives the transmission gear 508 to rotate. The transmission gear 508 meshes with the transmission teeth 5044 to drive the circular plate body 5041 to rotate relative to the guide circular plate assembly 503. The arc-shaped pushing groove 5042 pushes the solidified slag cleaning component 505 to spread outward under the guidance of the first guide groove 5033 and the first guide rod 5035, cutting the surface of the solidified slag at the furnace mouth of the steelmaking furnace.

When the circular plate body 5041 is rotated to push the coagulated slag cleaning component 505 to move outward, the spring 5037 is stretched under the pull of the transmission belt 506, which in turn drives the first sliding cylinder 5038 to slide outside the second guide rod 5036. As the coagulated slag cleaning component 505 spreads outward, the first sliding cylinder 5038 will spread outward synchronously, which makes it easier to ensure that the transmission belt 506 effectively transmits power to the second transmission wheel 5056.

[0028] The working principle of this invention is as follows: When cleaning the solidified slag at the furnace mouth of a steelmaking furnace, the transmission positioning shaft 502 is first inserted into the furnace mouth. Then, the fourth servo motor 509 drives the rotating shaft 5055 to rotate, which in turn drives the second transmission wheel 5056 and the first bevel gear 5059 to rotate. Through the cooperation between the transmission positioning block 50511 and the connecting transmission groove 505810, the second bevel gear 50583 is driven to rotate, thereby causing the connecting column 50582 and the cutting wheel 50585 to rotate. Then, through the transmission belt 506 and the guide 3039, all the cutting wheels 50585 are driven to rotate. At the same time, the first servo motor 501 drives the transmission positioning shaft 502 to rotate. The rotation then drives the circular plate assembly 504 and the solidified slag cleaning assembly 505 to rotate synchronously. Then, the third servo motor 507 drives the transmission gear 508 to rotate. The transmission gear 508 and the transmission teeth 5044 mesh with each other, driving the circular plate body 5041 to rotate relative to the guide circular plate assembly 503. The arc-shaped pushing groove 5042 pushes the solidified slag cleaning assembly 505 to spread outward under the guidance of the first guide groove 5033 and the first guide rod 5035, cutting the surface of the solidified slag at the furnace mouth of the steelmaking furnace. Then, the cutting is carried out at intervals at the furnace mouth of the steelmaking furnace, and annular grooves are evenly cut on the surface of the solidified slag at the furnace mouth of the steelmaking furnace, which facilitates the subsequent knocking of the solidified slag at the furnace mouth of the steelmaking furnace to fall. The second servo motor 505812 drives the third U-shaped positioning plate 50581 to rotate 90 degrees, so that the outer teeth of the second bevel gear 50583 mesh with the outer teeth of the first bevel gear 5059. Then, the fourth servo motor 509 drives the cutting wheel 50585 to rotate. Then, the third servo motor 507 drives the transmission gear 508 to rotate. The transmission gear 508 meshes with the transmission teeth 5044 to drive the circular plate body 5041 to rotate. The arc-shaped pushing groove 5042 pushes the solidified slag cleaning component 505 to spread outward under the guidance of the first guide groove 5033 and the first guide rod 5035. Then, the hydraulic rod 2 drives the furnace mouth cleaning device 5 to lift and lower, so as to longitudinally cut the solidified slag at the furnace mouth of the steelmaking furnace, which is convenient for the subsequent knocking down of the solidified slag at the furnace mouth. After the slit cutting work is completed on the solidified slag at the furnace mouth of the steelmaking furnace, the user pulls the handle 50588 upwards, causing the convex limiting block 50587 to slide inside the convex sliding groove 505811 until the convex limiting block 50587 slides down to the inside of the rotating circular groove 50589. Then, the user rotates the handle 50588, causing the handle 50588 and the striking positioning post 50584 to rotate 90 degrees along the convex limiting block 50587 and be stuck in the rotating positioning groove 50586. Then, the first bevel gear 5059 rotates, driving the cutting wheel 50585 to rotate, which in turn drives the handle 50588 to rotate and strike the solidified slag at the furnace mouth of the steelmaking furnace, causing the solidified slag at the furnace mouth to fall off. Since the surface of the solidified slag at the furnace mouth of the steelmaking furnace has been cut with cracks, the solidified slag at the furnace mouth of the steelmaking furnace can fall off quickly during the striking process of the handle 50588. When the circular plate body 5041 is rotated to push the solidified slag cleaning component 505 to move outward, the spring 5037 is stretched under the pull of the transmission belt 506, which in turn drives the first sliding cylinder 5038 to slide outside the second guide rod 5036. As the solidified slag cleaning component 505 spreads outward, the first sliding cylinder 5038 will spread outward synchronously, which makes it easier to ensure that the transmission belt 506 effectively transmits power to the second transmission wheel 5056.
