Description

A splash-proof slag baffle for metallurgical engineering furnace opening Technical Field

[0001] This utility model relates to the field of slag baffle technology, and in particular to a splash-proof slag baffle for metallurgical engineering furnace openings. Background Technology

[0002] Metallurgical engineering is a series of engineering and technical activities that involve extracting metals or metal compounds from resources such as ores and producing materials with good performance and economic value. Die-casting furnaces used in metallurgical engineering are important equipment for melting metal raw materials into a liquid state for die casting. Slag baffles are important auxiliary devices in the use of die-casting furnaces, mainly to facilitate the floating of non-metallic inclusions and control the slag within a specific area, thereby reducing the slag content in the molten liquid and improving product quality.

[0003] A search revealed that Chinese Patent Publication No. CN222043258U discloses a blast furnace slag baffle plate, which includes placing extension blocks installed on both sides of the slag baffle plate body into positioning grooves on both sides of the blast furnace body to prevent the slag baffle plate body from shaking on the blast furnace body, effectively blocking impurities and non-metallic debris in the molten liquid from flowing out from a specific area, thereby improving the quality of the cast billet.

[0004] In actual use, the aforementioned slag baffles are prone to oxidation, corrosion, or chemical erosion due to prolonged contact with high-temperature molten metal and slag, leading to a decrease in structural strength. However, if problems arise during use and the slag baffles are directly removed and replaced, the originally isolated molten slag may spread to the entire area of ​​the furnace opening, affecting the quality of solution extraction. If not removed in time, the slag baffles may warp, crack, or even break, resulting in the loss of their physical barrier function. Therefore, a splash-proof furnace opening slag baffle for metallurgical engineering is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above deficiencies, this utility model provides a splash-proof furnace mouth slag baffle for metallurgical engineering, which aims to improve the problem that existing slag baffles cannot be replaced in a timely manner when micro-cracks or surface peeling occur during use.

[0031] 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.

[0032] Referring to Figures 1-2, one embodiment of this utility model is provided: a splash-proof furnace opening baffle for metallurgical engineering, comprising a furnace body 1, with a baffle 2 installed above the furnace body 1. The baffle 2 can shield and protect the furnace opening of the furnace body 1 to prevent molten metal from splashing. When feeding, scooping molten metal, or pouring molten slag, high-temperature molten metal may splash accidentally due to operational vibration, excessive flow rate, or liquid surface fluctuation. The baffle 2, as a rigid barrier, can prevent molten metal from splashing into the operating area, avoiding burns to personnel or other injuries. The surrounding equipment includes a left baffle 3 and a right baffle 4 on the left and right sides of the enclosure 2. The surfaces of the left baffle 3 and the right baffle 4 that are close to each other are in contact with each other. The outer walls of the left baffle 3 and the right baffle 4 are in contact with the inner wall of the furnace body 1. The left baffle 3 and the right baffle 4 can be used in combination. When the left baffle 3 and the right baffle 4 are spliced ​​together, the furnace opening can be divided into two parts, front and back, to isolate the slag from the molten metal. This isolates the slag at the front of the furnace opening and prevents it from entering the mold with the molten metal.

[0033] A guide unit 5 is provided in the gap between the left baffle 3 and the right baffle 4. The guide unit 5 is used to guide and limit the installation of the left baffle 3 and the right baffle 4. The guide unit 5 includes a guide strip 51, which is fixedly connected to the left side surface of the right baffle 4. A guide groove 52 is provided on the right side surface of the left baffle 3. The guide strip 51 is inserted into the inside of the guide groove 52. When the left baffle 3 and the right baffle 4 are placed together into the furnace opening of the furnace body 1, the guide strip 51 can be inserted into the inside of the guide groove 52 to initially limit the left baffle 3 and the right baffle 4, so as to facilitate the installation of the left baffle 3 and the right baffle 4.

[0034] Referring to Figures 2-4, a fixing ring 9 is fixedly connected to the back of both the left baffle 3 and the right baffle 4. Workers can use tools such as hooks to move the left baffle 3 or the right baffle 4 with the fixing ring 9. The number of fixing rings 9 can be set multiple without affecting the scooping of molten liquid, so as to maintain the stable and limited movement of the left baffle 3 or the right baffle 4. A limiting cylinder 6 is fixedly connected to the upper surface of both the left baffle 3 and the right baffle 4. A limiting rod 7 is inserted into the inside of the limiting cylinder 6. The limiting rod 7 can move linearly in the left and right directions inside the limiting cylinder 6. The end of the limiting rod 7 near the inner wall of the enclosure 2 passes through the enclosure 2. When the limiting rod 7 moves away from the center of the enclosure 2, it can leave the inside of the limiting cylinder 6.

[0035] A moving unit 8 is provided on the outside of the limiting rod 7. The moving unit 8 includes a screw 81. The screw 81 is fixedly connected to one end of the limiting rod 7 near the inner wall of the enclosure 2. A handle 82 is fixedly connected to the end of the screw 81 away from the limiting rod 7. The operator can quickly rotate the screw 81 through the handle 82. A threaded cylinder 83 is threadedly connected to the outside of the screw 81. The end of the threaded cylinder 83 away from the handle 82 is fixedly connected to the outer wall of the enclosure 2. When the screw 81 rotates, it can move linearly in the left and right directions relative to the threaded cylinder 83.

[0036] Referring to Figures 2 and 5, a side plate 10 is fixedly connected to the outer side of the enclosure 2. When the enclosure 2 moves, the side plate 10 can move synchronously. A limiting hole 11 is opened on the upper surface of the side plate 10. A fixing rod 12 is fixedly connected to the upper surface of the furnace body 1. The fixing rod 12 is inserted into the limiting hole 11. Multiple side plates 10 can be arranged in a straight array on the outer side of the enclosure 2. Similarly, the number and position of the fixing rod 12 are adapted to the side plate 10. When installing the enclosure 2, the fixing rod 12 can be aligned with the limiting hole 11 and then the enclosure 2 can be moved down so that the fixing rod 12 is inserted into the corresponding limiting hole 11, thereby limiting the enclosure 2 and allowing the enclosure 2 to be placed stably. This prevents the enclosure 2 from shifting during splash protection, which would affect the use effect and the stable isolation of the left baffle 3 and the right baffle 4.

[0037] Working principle: First, place the enclosure 2 on the outside of the furnace opening of the furnace body 1, and insert the fixing rod 12 into the limiting hole 11 to limit the enclosure 2. After the enclosure 2 is stable, the operator can place the assembled left baffle 3 and right baffle 4 into the furnace opening. After the outer walls of the left baffle 3 and right baffle 4 are in contact with the inner wall of the furnace body 1, the operator can rotate the handles 82 on the left and right sides in sequence to drive the corresponding screws 81 to move towards the center of the furnace body 1 under the guidance and limitation of the threaded cylinder 83. At this time, the screws 81 can drive the limiting rods 7 to move synchronously, so that the limiting rods 7 on the left and right sides are inserted into the corresponding limiting cylinders 6 fixedly connected above the left baffle 3 and right baffle 4 in sequence, quickly limiting the left baffle 3 and right baffle 4, so that the left baffle 3 and right baffle 4 can be stably isolated.

[0038] When either the left baffle 3 or the right baffle 4 is damaged, taking the left baffle 3 as an example, a hook tool can be used in conjunction with the fixing ring 9 to hook and limit the left baffle 3. Then, the handle 82 on the corresponding side is turned to move the screw 81 outward, causing the limiting rod 7 to leave the inside of the limiting cylinder 6, thus releasing the limitation on the left baffle 3. At this time, the left baffle 3 can move linearly up and down, moving the new left baffle 3 above the damaged left baffle 3, so that the old and new left baffle 3 move down synchronously. During the movement, the guide strip 51 will directly insert into the new guide groove 52, ensuring that the right baffle 4 is further... The replacement process is seamless, ensuring effective slag isolation. Once the new left baffle 3 completely replaces the old one, turn the handle 82 again to insert the corresponding limiting rod 7 into the new limiting cylinder 6. This completes the replacement of the damaged left baffle 3. Simultaneously, slag isolation is ensured during the replacement process, preventing any impact on the scooping of molten metal. After replacement, the damaged left baffle 3 can be removed from the rear side of the furnace opening. The operation is simple. Furthermore, the separate design of the left baffle 3 and right baffle 4 allows for individual replacement when one side is damaged, eliminating the need to replace the entire baffle plate and reducing costs.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
