Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical equipment, in particular to a molten iron ladle which is convenient for slag removal. Background Art

[0002] The ladle is an essential piece of equipment in metallurgical production, used to hold and transport high-temperature molten iron. The taphole of a traditional ladle is located at the top of the ladle. When casting materials such as industrial silicon, which contain both floating and sinking slag, the ladle's location at the top requires a steep tilt during the casting process. This allows the slag to easily flow into the mold along with the industrial silicon solution, potentially leading to impurities in the casting. This can negatively impact product quality and performance. Utility Model Content

[0003] The problem to be solved by the utility model is to provide a molten iron ladle which is convenient for slag removal. The molten iron ladle which is convenient for slag removal can effectively separate the molten iron slag from the molten iron, and is convenient for slag removal.

[0004] In order to solve the above technical problems, the technical solutions adopted by the present invention are as follows:

[0005] A molten iron ladle that is convenient for slag removal comprises a ladle body, the ladle body being provided with a slag-liquid separation chamber with an upward opening, and being characterized in that a tapping nozzle communicating with the slag-liquid separation chamber is provided in the middle portion of a side wall of the ladle body, a movable plug being installed in the tapping nozzle, and a blocking structure capable of preventing the movable plug from detaching outwards being provided on the outer side wall of the ladle body; and a sedimentation area is formed at the bottom of the slag-liquid separation chamber.

[0006] Usually, the space below the molten iron outlet in the slag-liquid separation chamber constitutes the slag sedimentation area.

[0007] Typically, a refractory casting shell is provided inside the ladle body, and the slag-liquid separation chamber is provided inside the refractory casting shell.

[0008] Because a slag zone forms at the bottom of the slag-liquid separation chamber, and the tapping nozzle is located in the middle of the ladle body's sidewall, it is elevated above the slag zone, preventing molten slag from being discharged through the tapping nozzle. Furthermore, when molten iron is injected into the ladle body's slag-liquid separation chamber, due to the different densities of the molten slag and molten iron (the density of the molten slag is greater than that of the molten iron), the molten slag will settle and naturally separate from the molten iron over time. The molten slag will concentrate in the slag zone at the bottom of the slag-liquid separation chamber, while the molten iron will be above the molten slag. When casting is required, the blocking structure on the movable plug is first released, and then the movable plug is pulled outward from the tapping nozzle. This allows the molten iron above the slag-liquid separation chamber to be discharged through the higher tapping nozzle, while the molten slag remains in the slag zone. Furthermore, molten iron typically contains a small amount of scum, which floats to the surface of the molten iron after standing. During production, simply controlling the molten iron level above the tapping nozzle prevents scum from being discharged with the molten iron. When slag needs to be discharged, the opening on the top of the ladle body is tilted downward to pour out the molten iron slag.

[0009] In a preferred embodiment, the diameter of the taphole gradually increases from the inside to the outside, and the movable plug is a frustum-shaped plug with a smaller inside and a larger outside, and the sidewall of the frustum-shaped plug is in close contact with the taphole. The diameter of the taphole gradually increases from the inside to the outside, so that the taphole forms a diversion slope that gradually slopes downward from the inside to the outside.

[0010] In a further preferred embodiment, a guide connecting plate is provided on the outer wall of the ladle body, the guide connecting plate being located below the iron tapping nozzle and being covered with a refractory material layer. The provision of the guide connecting plate facilitates diverting the molten iron flowing out of the iron tapping nozzle to other containers.

[0011] In one preferred embodiment, the blocking structure includes a bolt and a hook capable of retaining the bolt's movable end. The bolt's fixed end is hingedly mounted to the outer wall of the package body via a pin. The bolt is positioned outside the movable plug, and the bolt's movable end engages with the hook. The snap-fitting arrangement of the bolt and hook provides a simple and reliable structure, securely securing the movable plug and preventing it from accidentally falling off. The snap-fitting structure of the bolt and hook is simple and easy to operate. Simply release the bolt from the hook and swing it toward the movable plug to quickly and easily remove the movable plug from the tapping port.

[0012] In another preferred embodiment, the blocking structure includes a bolt and two positioning blocks capable of positioning the ends of the bolt, each of which is provided with a positioning through-hole through which the bolt passes, and both positioning blocks are mounted on the outer wall of the package body, with the molten iron outlet located between the two positioning blocks. A stop block is provided at one end of the bolt, and the other end of the bolt sequentially passes through the positioning through-holes of the two positioning blocks. The bolt is located outside the movable plug, and the stop block engages with one of the positioning blocks. After passing through the positioning through-hole, the bolt spans across the outer end face of the movable plug, and then the stop block at one end of the bolt engages with one of the positioning blocks, thereby limiting the bolt, enhancing the fixing effect of the movable plug, and providing greater safety and reliability.

[0013] In a further preferred embodiment, a connecting ear is provided at the center of the outer end surface of the movable plug. The connecting ear is provided with a connecting through-hole corresponding to the positioning through-hole. The other end of the bolt passes through the first positioning through-hole, the connecting through-hole, and the second positioning through-hole in sequence. After passing through the connecting through-holes, the bolt forms a single unit with the movable plug, enabling the bolt to better block the movable plug. Furthermore, a connecting ear is provided at the center of the outer end surface of the movable plug to facilitate removal of the movable plug by the operator.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] The utility model can effectively separate the molten iron slag from the molten iron, making it easy to remove the slag, and is provided with a blocking structure for blocking the movable plug from being separated outwards, thereby preventing the movable plug from accidentally falling off and ensuring the safety of the operator.

[0021] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1, as Figure 1-2As shown, the molten iron ladle for facilitating slag removal in this embodiment comprises a ladle body 1, the ladle body 1 is provided with a slag-liquid separation chamber 11 with an upward opening, a water outlet port 12 communicating with the slag-liquid separation chamber 11 is provided in the middle of the side wall of the ladle body 1, a movable plug 2 is installed in the iron outlet port 12, and a blocking structure 3 capable of preventing the movable plug 2 from detaching outward is provided on the outer side wall of the ladle body 1; a slag area 13 is formed at the bottom of the slag-liquid separation chamber 11.

[0023] Typically, the space below the molten iron outlet 12 in the slag-liquid separation chamber 11 constitutes a slag sedimentation area 13 .

[0024] Typically, a refractory casting shell 14 is provided inside the ladle body 1 , and the slag-liquid separation chamber 11 is provided inside the refractory casting shell 14 .

[0025] Because a slag zone 13 forms at the bottom of the slag-liquid separation chamber 11, and the tapping nozzle 12 is located in the middle of the sidewall of the ladle body 1, the tapping nozzle 12 is higher than the slag zone 13, preventing molten slag from being discharged from the tapping nozzle 12. Furthermore, when molten iron 4 is injected into the slag-liquid separation chamber 11 of the ladle body 1, due to the different densities of the molten slag 5 and the molten iron 4 (the density of the molten slag is greater than that of the molten iron), the molten slag 5 will gradually settle and naturally separate from the molten iron 4 over time. The molten slag 5 will concentrate in the slag zone 13 at the bottom of the slag-liquid separation chamber 11, while the molten iron 4 will be above the molten slag 5. When casting is required, the blocking structure 3 on the movable plug 2 is first released, and then the movable plug 2 is pulled outward from the tapping nozzle 12, allowing the molten iron above the slag-liquid separation chamber 11 to be discharged through the higher tapping nozzle 12, while the molten slag remains in the slag zone 13. In addition, the molten iron usually contains a small amount of slag, which floats on the molten iron surface after standing. During the production process, as long as the molten iron level is controlled to be higher than the iron tapping nozzle 12, the slag can be prevented from being discharged with the molten iron. When slag is required, the opening at the top of the ladle body 1 is tilted downward to pour out the molten iron slag.

[0026] The diameter of the tapping nozzle 12 gradually increases from the inside to the outside. The movable plug 2 is a truncated cone-shaped plug with a small inside and a large outside. The side wall of the truncated cone-shaped plug is in close contact with the tapping nozzle 12. The diameter of the tapping nozzle 12 gradually increases from the inside to the outside, so that the tapping nozzle 12 forms a diversion slope that gradually decreases from the inside to the outside.

[0027] The blocking structure 3 includes a bolt 31 and a hook 32 that can capture the movable end of the bolt 31. The fixed end of the bolt 31 is hingedly mounted to the outer wall of the package body 1 via a pin 33. The bolt 31 is located outside the movable plug 2, and the movable end of the bolt 31 snaps into engagement with the hook 32. The snap-fitting arrangement of the bolt 31 and the hook 32 creates a simple and reliable structure that securely secures the movable plug 2 and prevents it from accidentally falling off. The snap-fitting structure of the bolt 31 and the hook 32 is simple and easy to operate. Simply release the bolt 31 from the hook 32 and swing it to the side of the movable plug 2 to quickly and easily remove the movable plug 2 from the molten iron outlet 12.

[0028] Typically, in actual operation of the ladle, the bolt bar 31 is arranged in a transverse direction (e.g. Figure 2 As shown), the bolt 31 is placed across the outer end surface of the movable plug 2 to prevent the bolt 31 and the hook 32 from affecting the outflow of the molten iron in the tapping nozzle 12. Figure 1 、 Figure 3 、 Figure 4 The bolt strip 31 is vertically arranged, which is just for the convenience of drawing and for the convenience of drawing how the bolt strip 31 and the hook 32 are installed.

[0029] Example 2, as Figure 3 As shown, the difference between this embodiment and embodiment 1 is:

[0030] The blocking structure 3 includes a bolt 31 and two positioning blocks 34 that can position the ends of the bolt 31. The positioning blocks 34 are provided with positioning holes 341 for the bolt 31 to pass through. Both positioning blocks 34 are mounted on the outer wall of the cladding body 1, with the molten iron outlet 12 located between the two positioning blocks 34. A stopper 311 is provided at one end of the bolt 31, and the other end of the bolt 31 passes through the positioning holes 341 of the two positioning blocks 34 in sequence. The bolt 31 is located outside the movable plug 2, and the stopper 311 snaps into place with one of the positioning blocks 34. After passing through the positioning holes 341, the bolt 31 spans the outer end surface of the movable plug 2. The stopper 311 at one end of the bolt 31 snaps into place with one of the positioning blocks 34, thus limiting the bolt 31 and enhancing the fixation of the movable plug 2, providing greater safety and reliability.

[0031] Example 3, as Figure 4 As shown, the difference between this embodiment and embodiment 2 is:

[0032] A connecting ear 21 is provided at the center of the outer end surface of the movable plug 2. This ear 21 is provided with a connecting hole 211 corresponding to the positioning hole 341. The other end of the bolt 31 passes through the first positioning hole 341, the connecting hole 211, and the second positioning hole 341, in sequence. After passing through the connecting hole 211, the bolt 31 forms a single unit with the movable plug 2, effectively blocking the movable plug 2. Furthermore, the connecting ear 21 is provided at the center of the outer end surface of the movable plug to facilitate removal of the movable plug by the operator.

[0033] Example 4, as Figure 5 As shown, the difference between this embodiment and embodiment 1 is:

[0034] A guide connecting plate 6 is provided on the outer wall of the ladle body 1. The guide connecting plate 6 is located below the tapping nozzle 12 and is covered with a refractory layer 61. The arrangement of the guide connecting plate 6 facilitates diverting the molten iron flowing out of the tapping nozzle 12 to other containers.
